1. How big is the size of the fishing and suede umbrella?

From the perspective of the diameter of the umbrella surface, the main size of 1.8 meters, 2 meters, and 2.2 meters is mainly based on the diameter of the umbrella surface.When choosing a fishing umbrella, the fishing umbrella can buy an umbrella surface for two meters in diameter. Too young will not cover the rain. If it is too large, the trunk will not be put.The shape of the fishing umbrella is a combination of transforming from the beach umbrella and the British Tent. Its materials used are aluminum alloy and fiber. Using fishing umbrellas during fishing can not only block rainwater, but also block the sun.

2. How to install the fishing umbrella

1. First of all, insert the iron fork at the bottom of the fishing sun umbrella into the soil. The edge of the fishing pond is generally the soil structure that can be easily inserted.

2. Then connect the support rod (generally equipped with a rotatable screw) to the iron fork.

3. Open the fishing Solar umbrella and insert the upper bayonet of the hardcore. Some bayonet design has a direction adjustment, which can adjust the direction, and some can not adjust the direction.

4. After inserting, the lock port is completed and the installation is complete.

Third, precautions for fishing umbrellas

1. The fishing Parasol you buy back must be installed and unloaded for the sunshade when used. Be careful, pay attention to putting it lightly, do not throw it at will.

2. When using a Parasol, check whether the screws of the intersection are tightened, and check whether the bracket is bent or deformed.If such a situation occurs, the Parasol should be taken to repair.

3. Pay attention to windproofing for Outdoor fishing. Otherwise, the Parasol is likely to be overturned, especially when the guardian leaves, pay attention to drop the Parasol's foot to the first section.

4. The new umbrella should not be put on hold for a long time, so as not to store long for a long time.Do not fold it with water after the umbrella is used. You should hold the umbrella. Use a soft cloth to wipe the inner and outer umbrella rods and umbrella surfaces, hang it upside down to dry it in the ventilated place, and then close the umbrella and collect it.In order to prepare for the next time, the life of the umbrella can be prolonged, it will not rust and corrodes, and it is also convenient for future use.

5. In addition, the Solar umbrella should be wiped and dried after the room temperature, and then put it away. If you ca nt get hot, you can put it away.

4. How to buy fishing umbrella

1. When choosing a fishing umbrella, you can touch the fabric of the umbrella surface. The fabric of the fishing umbrella surface is thicker than the ordinary umbrella.You can also pull the fabrics with both hands. See if the position of its stitching is strong and firm, and look at whether the surface of the fabric is delicate, uniform, and shiny. Because the fishing umbrella is often exposed to the sun, the fabric must be strong.

2. When choosing a fishing umbrella, you should also test the toughness of the umbrella Bone.experience with both hands, tough tough testing of fishing umbrella bones, twist the umbrella Bone into a bow shape to see if it can be restored. If it can be restored, it means that its umbrella Bone is better, then the wind resistance ability is better.Essence

Sweet potato planting

planting technology

1. Soil

It is advisable to be deep, loose, well -drained, organic with more organic matter, and a certain Fertilizer.This kind of soil is loose, with good breathability, short -shaped shapes, neat, bright Skin, good food, high out of rate, and good storage resistance.

2. color

Seecn beds should be selected from the sun, high terrain, good drainage, convenient management, and fertile soil. It is best to be new seedlings. Old seedlings are often infected with dark spots and nematode diseases.Flink the seedlings of the seedlings once before planting potato, so that the soil grains are fine, the soil is loose, the farming layer is deep, and the chart is raised and raised.The seedlings are determined, generally no more than 6 meters.

3. Select planting

Select healthy potato species with this variety characteristics, distinctive Skin color, strong living power, moderate size (0.15-0.25 kg/piece), strictly eliminate the dark Skin color, cold damage, softened potato pieces, too much water loss, too much water loss, too much water loss, excessive water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water loss, too much water lossMore, and tetanus potato pieces with 70%methyltotobadin 300 times liquid before sowing for 10 minutes to disinfect, the effect is better.

4, density

Plant density varies from season, variety, use, etc.spring and summer potatoes are 3,000-5000 plants per mu, and autumn and winter potatoes are 4,000-6000 per acre.Strive for the leaf area index in the heyday of stems and leaves reached 3-4.5.Due to the continuous cutting of stems and leaves, the feed sweet potatoes can be encrypted to 6000-8000 plants per mu under the condition of multiple Fertilizers.

5. Temperature

The higher the temperature in the range of 16-35 C, the faster and more sprouts.16 C is the minimum temperature of the potato blocks, and the most suitable temperature range is 29-32 C.When the potato block is above 35 C for a long time, due to the great breathing intensity of the potato blocks, the consumption of nutrients, it is prone to "bran heart".When the temperature reaches above 40 C, it is prone to damage to hot and rotten potato.

Diseases and insect prevention

The main diseases of Sweet potato are Sweet potato black spots, Sweet potato stem neck disease, Sweet potato soft rot, potato plague, Sweet potato sore disease, Sweet potato vine disease, Sweet potato root wirling disease, Sweet potato rot, Sweet potato virus disease, Sweet potato purple patternYu Diseases and so on.The main pests of sweet potatoes include nasal insects, crickets, golden Turtles, ground tigers, and Sweet potato moth oblique night moths.The prevention and control of Sweet potato diseases and insect pests should adhere to the principles of preventing and comprehensive prevention.

Mainly controlling diseases and insect pests:

1. Choose a variety of disease resistance, pay attention to the disease quarantine of potato and seedlings.

2. Cultivate disease -free and strong seedlings, choose disease -free potatoes and seedlings from no library areas, or use decontamination seedlings.

3. Use a 50%bacterial or 50%methyltotobadin 500 times liquid to soak the Sweet potato vine for more than 2 minutes, and plant it after cooling.

4. Datian found that the diseased strain should be removed immediately and burned, and sprayed with a 50%fungus spirit 1000 times liquid. According to the situation, it can be sprayed once every 7 consecutive days until the root is eliminated.

5. Thoroughly clean up the diseased plants during harvest, pay attention to the rotation of water and drought, strengthen the management of water and Fertilizer, pay attention to drainage and ventilation, and appropriately appropriately appropriately apply plant ash and lime to make the plants grow strong and strengthen the disease resistance.

6. The main pest control of sweet potatoes can be used with pesticides such as the fear of enemy, killing pine, polyester pesticides, etc. According to the correct explanation, it is usually sprayed in the afternoon.

Potato planting

planting technology

1. Select the plot

The plot suitable for cultivating potatoes should be loose, good for soil, good permeability, rich organic matter, flat terrain, close to water, and convenient discharge irrigation.

2. Reasonable rotation

Potatoes should not be continuous, because the continuous work can increase the pests and pests of the soil, which can easily cause serious lack of certain elements in the soil. The natural balance of the soil microorganism is destroyed, the accumulation of harmful substances secreted by the root system will affect the yield and quality of potato.The previous crop can be rice, corn, green onion and garlic, melon, etc.

3. Reasonable fertilization

It is best to use balanced fertilization (formula fertilization).The Fertilizer of potato is fertilized. Tests have proved that when the tuber produced per mu is 1,000 kg, it is necessary to absorb 5.6 kg of nitrogen from the soil, 2.2 kg of phosphorus, and 10.2 kg of potassium.Potatoes need the most potassium for Fertilizer three elements, the secondary nitrogen, and less phosphorus.

yam planting

planting technology

1. Put the buds of yam seeds into the soil. The interval between lines and lines is about 1 meter, and about 10,000 pieces per acre of land are planted.

2. The growth process of plants such as yam needs to keep the surrounding environment high temperature and dryness, and do not like frost.About 35 days is enough to see Chang Miao.

3. Because the rhizomes of yam are relatively weak, they need to grow upward after emergence, otherwise it will easily wither.

4. Dorodes once a month for half a month, until about half of the shelf height, and then just remove the weeds.

5. Apply Fertilizer at the appropriate time and inhibit the growth of the ground. During the flowering period, fertilization can also be used to increase yield.

6. Properly increase some irrigation. Although yam is a drought environment, it is necessary to water in moderation in continuous drought weather. In the case of continuous heavy rain, it is necessary to drain it in time.

taro planting

planting technology

1. Temperature

taro requires high-temperature and humid environmental conditions. The bulb of the taro at 13-15 C began to germinate.The moderate growth temperature during the seedling period is 20 to 25 degrees, and the temperature growing temperature is 20 to 30 degrees.

2. Water

Whether it is a taro or a riru, it likes moist natural environment conditions.In particular, the leaf is strong and the period of the galvan stems is large. The amount of water requires a large amount of water.

3. Light

taro is more resistant to weak light, and the intensity of light is not very strict. The formation and expansion of the ball stems require short -day conditions.

4. Soil

taro is a happy crop, and its ball stem is formed in the underground soil layer. Therefore, it should be selected to be rich in loam or clay loam with rich organic matter and deep soil layers.

Cassava planting

planting technology

1. Origin environment

Edible cassava generally needs to be planted in areas with a frost -free period and an average annual temperature of 18 C and above.The origin environment of non -rigorous cultivation of cassava should meet the requirements of DB45/T410.

2. Selection and rectification

It should be selected to plant flat or mild sloped sand soil. For example, the planting site needs to be rotated by 2 years, 3 years, etc. The rotation crops are preferably crops such as peanuts, corn, soybeans and mung beans.The whole land is carried out in about one month before planting. Generally, it is two plows and two rakes. It is advisable to be a cultivated land depth of 30-40cm, making the soil flat and loose.3. Variety selection

The varieties of excellent characteristics such as low hydrocyanic acid content (below 100 mg/kg), high yield, high -yield, disease -resistant pests, and strong anti -inverse characteristics.my country mainly has a variety of cassava varieties such as Cutchota, South China No. 9, South China 6068, No. 12 South China, and GR891.

4. planting

The suitable planting time of cassava in my country is from February to April. It is advisable to choose the main stems of full maturity, 2-4cm of stem and diameter, dense section, stem Skin and buds, and disease-free pests. Stems, cut it into 15-20cm in length.The planting method can adopt four methods: flat, oblique insertion, and direct insertion and peaceful insertion. It is better to adopt a ridge covering membrane to plant or take a ridge dewdo plane.1M 0.8m is better.

Prevention and treatment of pests and insect pests

In my country, there are fewer cassava Diseases and diseases. Pests and insect pest control must adopt the principles of prevention -oriented and comprehensive prevention. agricultural prevention and control must be used to prohibit the use of pesticides and mixed preparations for the use of countries.When there is no large area of diseases and insect pests, the method of artificial removal should be used and destroyed in time;Secondly, measures such as weeding and soil cultivation can be created to create ecological conditions that are not conducive to the occurrence of pests and insect pests, but it is beneficial to or not hinder the growth of cassava growth.If the area of disease and insect pests is large, high -efficiency, low toxic, and low -residue pesticide varieties need to be selected for prevention and treatment.Cotenato grass damage is recommended to use artificial, machinery and cultivation techniques to prevent removal, such as ground film covering weeding technology, plowing Fertilizer and soil technology, and setting.

1. The role of football leg protection board

The leg protection plate is to protect the tibia of the calf, which is also known as the tibial plate.Due to the high confrontation of football games, the probability of players to be kicked to the calf is very high, so it is necessary to wear the tibia that suits your legs to protect your tibia in the game.From a physics point of view, the leg protection board is decentralized and buffer originally applied to the impact force on the calf.The gap between the leg protection board and the legs can play a buffer, and the flesh between the leg Bone and the legs also has a buffer effect to prevent fractures.

If the player does not wear the leg protection board, it is likely that tibial or fibula fractures are likely to occur when they have a strong force on the calf. In severe cases, they may even cause a thigh Bone fracture or knee cross ligament to tear.

It is clearly pointed out in the FIFA regulations: football players must wear sufficient protection to provide a certain protection. The leg protection board made of similar materials such as plastic and rubber, and the leg guard board must be completely covered by football socks.

2. How to choose a leg protection board

Generally speaking, the leg guard board is divided into two types based on the type of wearing: one is a traditional plug -in type, and the other is a sheet with socks.For example: Nike's Mercurial Blade Hinge, Adidas's F50 Adizero, and Puma's Evopower.Traditional plug-in boards such as SELECT, G-Form, Youzbao GMBH, etc.

From the shape of the leg protection board, we can simply divide it: big board and small board.The small board is relatively lightweight and relatively comfortable. Generally, the frontcourt players who like to break through the plate will choose small boards. Of course, the protection effect it can play is relatively poor.And many large leg protection plates with ankle -wrapped ankles at the same time. The same large plates are also worse in terms of flexibility and comfort. Generally, most of them are in the middle and backcourt defensive players tend to choose this type of leg protection board.

Be sure to choose a qualified product when choosing the leg protection board, a product that makes you feel comfortable.

Comfort can be considered through size, weight, thickness, fit, sweating not stuffy, and whether it will be challenging.For appearance, it is set in socks anyway, you can do not consider it.

3. How to bring football leg protection board

1. First of all, we need to put on football socks, but do not pull the ball socks to the knees.

2. Then, look for the calf parts protected by the leg protection board (usually a little bit lower in the middle of the calf), and insert the leg guard plate into the shoe socks.

3. Press the leg guard board, pull football socks to the knee, and complete the wear of the legs.

Note:

1. football leg protection boards include large plates, small boards, standard boards, etc., you can buy it according to your preference.

2. L is left, R is the right, and the leg guard board is generally marked. Remember not to wear it.

Having a sailing boat means to have a city -state that lives independently and freely at sea; with a sailboat, you can enter a port of any port on the sea ...Some people who get up are not an excessive price.However, so far, the sailboat is still a game that is only played by a small number of people in Mainland China.

1. Sailing equipment

As the so -called work is good, we must first benefit its instrument.When it was really going to sea, there was no professional sailing equipment.Due to its special environment, the sailing movement needs to be armed throughout the body.Sailing clothes, ropes, sunscreens,Sunglasses... Every detail may affect your progress of learning to control sailing.Therefore, don't forget to check the equipment before boarding the Ship.

Voyage

The weather on the sea is easier to change than the shore, so it is very important to wear and equipment correctly in this sport.You don't have to spend a lot of money on the equipment. Here is some simple guidance for your basic equipment:

Wear loose clothes.It takes a lot of movements to operate the sailing boat, so wearing can give you enough clothes for you

Carry extra clothes in luggage Bags.In order to add clothes or wet water when cold, you can change your clothes.

Wear light and breathable clothes in hot days.It is best to wear light -colored clothes. The clothes you lead can protect your neck from exposed to sunlight. The clothes with long sleeves can protect your arms from exposed to sunlight.

Use sunscreen (SFP15 or higher) to protect your Skin, and even so on a cloudy day, it is best to apply it frequently.

Wear a hat to protect your eyes and make your head from being shined with sunlight.In cold days, wearing a hat can warm the head.

Wear Sunglasses (at least 90%).Polarized mirrors can greatly reduce the dazzling feeling of water.

You must wear anti -slip shoes.In order to stand on the slippery deck.tennis shoes that are not broken sole will be a good choice. Of course, sailing shoes are the best choices, because the soles of the sole

The rubbing force is very large and dry very fast.Don't wear sandals or other toe shoes, sooner or later you will hurt your toes.

waterproof navigation boots will keep your feet warm and dry in cold days.

Daihang sea gloves can prevent your hands from being scratched and increase friction.It is best to wear waterproof gloves in cold days.

Lifeline is a must -have equipment for navigation.The life jacket should be fitted and has quality assurance.

Wear a few more layers in cold days.When you feel cold, your operation skills will be greatly affected, so wearing a few more clothes is a wise choice.Avoid wearing cotton clothing, wear

Clothes that can still keep warm after wet, such as cortex or polyester fiber clothing.Dedicated cold prevention clothing, dedicated cold -proof clothing can keep you warm and dry in bad weather.There are several styles to choose from:

Standard two -piece set, including a waterproof jacket with a hat pocket and an independent suspender pants.

Conjusational clothes will make you more dry, but you cannot take off your shirt or pants alone to adapt to changes in temperature.

On some particularly humid ships, crew members often wear wet warm clothes similar to divers.

Dry -style warm clothing is a suit that allows you to isolate water. They seal your neck, wrist and ankle tightly.They can prevent water and keep warm.

Safety equipment

In addition, there should be complete safety equipment on the sailing.Safety equipment not only protects Ship equipment, but also protects individuals. The crew must know the location and correct use of these equipment in order to prevent accidents during the movement.Sailing needs to prepare the following safety equipment on sailing on the shore:

Safe vests -Each person must have a qualified life -saving vest, and children must prepare special size life vests for them.

Life Rings -placed on the Ship that is easy to get on the boat, and once someone falls into the water, it can quickly throw it into the water fall.

FIRST AID Kit -Applicable first -aid drugs and items.

Bilge pump -manual or electric pump, which can quickly discharge the chamber water.

Bucket (bucket) -The rope of about two meters can be used urgently when the cabin is in water.

In addition to the above, if you want to travel long, you can also prepare excess anchor cables, waterproof flashlights, fire extinguishers, Gangpu, Haitu, signal bullets, wide -leaf short paddle, drainage equipment, horn, compass, sufficient water, knife, pliers, pliers, Screws, rolls and other tools to prepare from time to time.

First boarding

For the first time to board the Ship, pay attention to boarding etiquette. First of all, the captain's consent can only be boarded, just like invited to enter the house of others.When boarding the Ship, you should be very careful, especially when you are low tide, use a ladder or connect to the large boat by a small boat or a small boat. When crossing the side cable, you should cross the back to maintain the center of gravity of the body.Proper locations and prevent the hull of the hull may move into the water.

The sailing club often keeps tilting or suddenly unpredictable, especially for beginners who are not accustomed to activities on the tilted Ship.The string cable, the top pole of the cabin, or any fixed devices on the Ship can help you stand firm.When walking around, the body is slightly bent and walks, keeping the center of gravity, and be careful not to hit the horizontal pole or let it hit you.Walk on the deck to keep on the upper side for safety.

2. Small boat site and instructions

1. Former sail (jib): sail used in front of the main mast.

2. HeadStay or Forestay: The top of the mast can be pulled forward to the front boat, and the steel cable on the front sail can be buckled.

3. SHEET: The main control of the rope can be released or tightened and fixed. This picture refers to the front sail.

4. Mainsail: The largest sail that is raised after the main mast is also the source of the main power of the entire sailing boat.

5. Battens: The flat bars inserted from the back edge of the sail, in order to maintain a good sail shape.

6. MainSheet: Rope to control the angle of the main sail.

7. Boom: elongated, used to fix the bottom of the main sail.

8. BOOMVANG: The cable tightened or supported by the sail truss to prevent the sailing truffle up.

9. Mast (MAST): The long rods made of wood or aluminum are supported by steel cables for lifting and stretching sails.

10. SHRouds: The tension used to fix the side of the mast.

11. Centerboard: Under the hull, you can adjust the depth of water (mainly axis -based heart, front and rear lift).

12. Rudder: The device used to control the Ship in the direction.

13. Boat (BOW): The front of the hull.

14. Stern: The last part of the hull.

15. Hull: The shell of the Ship.

3. Preparation before playing sailing

1. Operation basis

(1) Look at the basic knowledge of sailing, understand what the sailboat is driving, and see the relationship between the wind, sail and boat in all directions, see the basic chapter of the sailboat in the forum technology post.

(2) Keep in mind the basic guidance and safety reminder of the teacher before launching. Sailing is a sports Tool with safety knowledge, including wearing a life jacket to understand the use of safety equipment. Pay attention to the difference between the boat and the big boat from the preparation of the Ship on the dock.To control the balance of the boat and your own center of gravity, it is generally necessary to quickly move the Ship to move the center of gravity to the center of the Ship to avoid the boat cover.Check whether each rope is in normal state.

(3) After boarding the Ship, pay attention to lift the sails because of the cooperation, and the boat can generally rise on the shore.

(4) After sailing, safely leave the dock.To judge the direction of the wind first, you can generally judge through the wind direction indicator on the boat or the wind line tied to the side branches. Generally, the range of 45 degrees in the direction of the wind is the range of 45 degrees.Sailing, of course, to adjust the angle of sails from the perspective of wind.

(5) After a period of familiarity, we can master the basic operation of the former sails, and start learning how to take the helm. The boat we learn is the rudder of the pushing rod. It is more sensitive than the rudder wheel.Basic driving in turn to understand the relationship between wind, front sail, main sail, main sail, Ship's order and rudder's sense of rudder, and can basically understand the basic essentials and feelings.

2. Important angle

(1) Wind direction angle: The term for sailing motion sailing, refers to the angle between the wind between the end of the same sailing boat.The motivation of the sailing Ship mainly depends on wind power.And the size of the wind direction to the promotion of sailing is very important.Athletes must correctly grasp the wind direction and angle in order to fully use the wind to drive sailing.

(2) Different wind direction angle divide the degree

The wind direction angle of the top wind is between 0 degrees and 30 degrees; the wind direction angle of the front wind is between 30 degrees and 60 degrees;At 80 degrees 1 100

Between degree; The wind direction angle of the Smooth wind is between 100 degrees and 170 degrees; The wind direction angle of the tail wind is between 170 degrees and 180 degrees.

3. Sailing knot

Since ancient times, skilled use of knots is one of the very important sailing skills, because it will save the life of the crew.Different use cables use different materials.Due to the high tensile strength, nylon rope can be used as anchor rope or a boat rope.Dakun has little resistance and can be used as a flag rope or main sail.Polypropylene can float and can generally be used as a tie rope.

(1) Single knot.The wide range of uses can prevent loosening.

(2) Lilac knot.It is not a very strong way of knotting, which can be used as a short -term link.

(3) 8 -character knot.Used for the top of the flag rope or main sail.

(4) Rolling knot.Used to connect with coarse cables.

(5) Horn knot.Used to connect the cable angle of the same system.

(6) Two halves.Used for the same column, ring, etc.

It is also important to exercise the skills to handle cables.First of all, take the cable carefully.Before handing, the disk is divided into two parts.When throwing the smaller part of the cable, you need to keep the hand shape so that the other half of the cable is naturally pulled out in the other hand.
