1. Burning pot

The plain pot is a mud tile pot. It is the most commonly used plant container. It can be divided into two types: red and gray pots.There are various specifications, the smallest diameter is about 10 cm, generally 14_33 cm, and the larger is 39 59 cm.The water and exhaust drainage performance of the plain pot is good, which is conducive to plant growth. It is widely used in the cultivation of seedlings and the cultivation of seedlings.This kind of Flower pot is not enough. It is rough. When cultivating finished seedlings, you should try to use a small pot as much as possible so that you can place it in a slightly larger pot when displaying decoration indoors to make up for the shortcomings.

2. Zisha pot

Various flowers and plants are engraved on the purple sand basin, with a variety of styles, harmonious colors, simple and elegant, and antique beauty. It is more suitable for small leaf species for small leaf species on the indoor countertop.The disadvantage of this basin is that the water permeability of the water is slightly worse, and the appropriate species must be selected when used.

3. Plastic basin

Plastic pots are one of the commonly used plant containers for indoor leaf -viewing plants. They can be divided into hard plastic pots and soft -holding plastic basins.Hard plastic basins are generally small in size, light and beautiful, colorful, and are mostly used for viewing and cultivation, but their ventilation is poor and not conducive to growth. Therefore, it is not suitable for long -term planting.It is only used, and it must be loose, ventilated and drained multi -porous substrates with good ventilation and drainage performance.The soft plastic basin is only used for the nursery of indoor leaf -viewing plants, and is generally not used for ornamental cultivation.Can plastic Flower pots raise flowers & gt; & gt;

4, glaze basin

The glaze pot is strong and gorgeous, but the drainage ventilation performance is poor.It is often used as a pelvan, which can also be used directly to cultivate large leaf -viewing plants, but it must be equipped with loose porosity matrix, otherwise the plant growth is poor.

5. Wooden basin

The wooden basin is used to cultivate large leaf -viewing plants and can also be used to cultivate some fleshy.Its specifications can be determined according to actual needs.This kind of inside and outside of the pot can paint different colors to improve the service life and coordinate with the color of the plant.It has a light scenery, good breathability, strong water and Fertilizer, low cost, and low cost. It is suitable for planting of various flowers. In addition, it can also be determined and processed according to the shape, size and cultivation of flowers according to the shape, size and cultivation of flowers.This pot is easily rotted by the erosion of water, Fertilizer, and microorganisms, and has a short service life.

6. Cement basin

Cement Flower pot is usedCementPlaced it.It is simple, with different shapes, and moderate weight, but it is suitable for garden and balcony greening.

7. glass basin

The glass flower is not breathable and cannot be watered.The glass is transparent and you can see the internal moisture.In summer, the glass flower must be placed in a cool place.Put the water layer with a glass flower, you can use pottery grains or large light stones. This individual is casual.The glass flower is suitable for leaf insertion.

8.Porcelain basin

Porcelain pots are fired with porcelain soil, which is the best in the ceramic basin.It is bright in color, beautiful in appearance, and many varieties of color, but it has poor breathability and water seepage. It is difficult to master the wet and wetness of the pot soil with this pot.It is best not to plant flowers directly, only suitable for flowers for flowers.

precautions

In addition, there are all kinds of materials for decorative materials, such as glass tanks, vine products, stainless steel clads, etc. This type of pot is beautiful and generous, which can add a gorgeous and colorful atmosphere.But for display, not cultivation.

1. Obstacle lighting

Install the lighting on the building for obstacles.Such as the flying obstacle logo on the top of the high -rise building, the navigation obstacle logo lamp installed on the buildings on both sides of the channel.Obstacle lighting should use lamps that can transmit red light. When installing obstacles, the following requirements should be met:

(1) General high -rise buildings only install obstacle lighting at the top, buildings with large horizontal area or intensive high -rise buildings, in addition to installing obstacles at its highest top, but also equipped with obstacle Lights on the top of its outside corner.Items

(2) The height of the chimney is more than 100m. In addition to installing obstacles at the top, an obstacle light should also be installed at a height of one -half.In order to reduce the degree of pollution of the barrier light at the top of the chimney, the obstacle light can be set lower than the 4-5m of the chimney mouth.In order to ensure reliability, the three obstacle Lights are generally installed into an equivalent triangle so that one of the obstacles can still see the light from the direction of the direction.

2. What are the aviation barriers

Aviation obstacles are special lamps that identify obstacles.The light -strong aviation obstacle light is Changliang. The mid -light strong aviation obstacle light and high -light strong aviation obstacle light are flashing. The flash frequency is not less than 20 times per minute and 70 times per minute.

Aviation obstacle Lights are generally divided into three types: low light, strong light, and high light strong. The vertical and horizontal distance between the aviation obstacle Lights is greater than 45 meters and its facilities. The three obstacle logo Lights can be used with each other.

A clear warning effect.

3. Under what circumstances must set up aviation barrier Lights

Aviation obstacles are special lamps that identify obstacles.The function is to show the outline of the structure, enabling the aircraft operator to judge the height and outline of the obstacles, and play a lamp in a warning function installed on the obstacle.

In order to distinguish the lighting Lights of general uses, the aviation barrier Lights are not often on but shiny. The low -light and strong aviation obstacle Lights are often on.It is less than 20 times per minute, not more than 70 times per minute.

Aviation obstacle Lights are generally divided into three types: low light, strong light, and high light strong. The vertical and horizontal distance between the aviation obstacle Lights is greater than 45 meters and its facilities. The three obstacle logo Lights can be used with each other.

A clear warning effect.

Situation 1: The high -protection of the airport is high or the ultra -high buildings and structures should be set up. All aviation obstacles and signs should be set up.

Situation 2: For artificial and natural obstacles that affect the safety of flight safety on the route and the flight area, aviation obstacles and signs should be set up.

Situation three: For the tall, tall buildings and facilities that may affect the safety of the flight, you should set up an aviation obstacle light and logo and pay attention to maintaining normal working conditions.

Fourth, setting distribution of aviation barriers

1. Obstacles The highest point and edge of the obstacle to the setting of the obstacle light (ie, the height and the width) of the obstacle.

2. If the top of the object is more than 45 meters above the ground on the ground, an obstacle light must be added to the middle layer.Consider the intermediate layer to add obstacles).When the building is equipped with an intermediate barrier light near the urban and residential areas, it should be considered to avoid making residents feel uncomfortable.It is generally required to see the light from the ground.

3. The obstacle lamps set up by the vast building complex should be seen from all aspects of the outline of the object. The horizontal direction can also be set at a distance of about 45 meters.

4. For 105 meters of ultra -high objects, facilities, or pull towers, roof tower, etc., the light -strong A -type obstacle light at the top should be set on its top, and the white flash should be set.lamp.

5. Ultra -high objects above 150 meters (such as radio and television tower, large crossing cable bridge, etc.) shall be set up at the top of the highlights and strong A -type obstacle Lights, and it should be used in conjunction with the middle and high -light strong obstacles.

6. The tower of the ultra -high voltage transmission wire should be set up with a high -light strong B -type barriers and a three -layer synchronous flash.The position of the tower is the minimum drooping point and the middle position of the two, and it needs to be located along the direction of the cable.

7. For chimneys or other similar buildings, the top obstacle light must be between 1.5-3 meters at the top. Considering the pollution of the chimney to the lamp, the obstacle light can be installed in the area below 4-6 meters (detailsSee the National Standard Festival).

8. Regardless of the obstacle light, the number and arrangement of the obstacles of the obstacles at different heights should be seen from the outline of the object or object group from all directions, and the synchronous flashes of the obstacle light should be considered to achieve an obvious warning effect.

Solving fish seedlings bait good methods common fish fry opening bait

Directly increasing rotor worms in the pond is an effective way to solve the bait of fish seedlings, reduce production costs, and improve the survival rate of fish seedlings.

The rollerworm in the drainage and clear ponds rely on the dormant eggs in the bottom mud to re -germinate.According to determination, in the bottom mud of fish farming ponds, there are more than 10 million rotor eggs per cubic meter per cubic meter. They are "seeds" of wheelglin breeding the following year.The drainage can increase the heat of the dormant eggs in the bottom mud. The Qingtang can remove the enemy's enemy damage and replace the new water itself a benign stimulus.

Tests related to Organic fertilizer show that every 667 Square meters of ponds invest about 26 kg of cow dung or human feces urine to meet the food needs of wheel worms.

Soon after the control of the enemy's pond wheel worms, the water flea also started, because both used bacteria, crumbs and algae as the food, and the filtering ability of the water flea was stronger than that of the wheel worm.Worms are suppressed due to lack of food.Kill the flea with appropriate potions and retain the wheels.

When the new water is applied to the environmental conditions, the wheel worm breeds very quickly. It is 1-2 days after the peak, and hypoxia is prone to occur. Therefore, new water should be added.

In order to ensure the survival rate of fry, in the early stages of breeding, it is often necessary to provide palatable, rich, and nutritious open bait.At present, several commonly used bait in the cultivation of seedlings are egg yolk, soy milk, wheels, algae and aquatic micro -ecological preparations.

1. Egg yolk

Egg yolk is a commonly used fish -opening bait. In the production, the egg yolk can be filtered by 80 measuring silk to make the egg yolk particles smaller, so that it is evenly distributed in the water in the water, which can keep the suspended time around 1h.The amount of bait is within the appropriate range, and the egg yolk can be eaten by the fry better.However, it should be noted that this kind of bait is easily settled and lost, and the water quality is easily corrupted after entering the water, resulting in the slow growth of the fry and the low survival rate.

2. Soymilk

Soy milk is rich in protein and can meet the nutritional needs of fish fry, but soy milk has low nutritional value, is not easy to digest and absorbs, and it is easy to form suspension in water, affecting soluble oxygen, and easily fermented.Promote the rapid reproduction and growth of floats in water bodies, and indirectly provide bait for fish fry.

Three, wheel worms

The size of the wheel worm is 166 m* 230 m. It has good palatability, the highest crude protein content, and the crude fat content is second only to egg yolk, and contains unsaturated fatty acids necessary for a large amount of fish fry, with high nutritional value.The swimming speed is less than 0.02cm / s, and the distribution in the water layer is relatively uniform.Wheels can grow and reproduce in the seedling water body, which not only maintains the stability of its nutrients, but also contaminates the water quality of seedlings.In addition, the research of wheel worm cultivation methods is very rich, and the cultivation technology is relatively mature, which can ensure that the wheel worms have sufficient sources. Therefore, wheelglintes are effective ways to solve the bait of fish seedlings, reduce production costs, improve the survival rate of fish seedlings and quality.

Four, algae

Algae individuals are smaller than wheel worms, and are suitable for use in the early days of the fry opening.With the growth of the fry, the split mouth widen, and wheel worms have become its most suitable bait.The two can complement each other.

5. Aquatic micro -ecological preparation

Aquatic micro -ecological preparations are small, non -toxic side effects, non -pollution and residues, can effectively improve the ecological environment of the breeding, improve immune capacity, inhibit pathogenic microorganisms, and greatly increase the growth rate and survival rate of fish fry.For example, optical bacteria are a nutrient -rich and highly nutritious bacteria. The bacteria are rich in amino acids, folic acid, B vitamins, especially vitamin B12 and biotin content, and physiological activated substance q Q.The volume is 1/20 of the small ball algae. When the organs such as fishes, shrimp, shellfish and other digestive systems that are just hatched are not fully differentiated, optical bacteria can be sucked into the body through gills, so that the fishes have not been completely absorbed in the yolk sac that have not been completely absorbed completelyAt the same time, you can take the bait from the outside to make up for the lack of endogenous nutrition.

1. How does the Fish rod card festival cause

In the process of fishing, we should be able to encounter this phenomenon: the fishing rod is closed when the fishing rod is collected, and how can we not collect it hard.The main reason for the fishing rod card festival is the following reasons:

1. Water at the interface or rain wet caused a local vacuum of the fishing rod.

2. During the fishing rod, the festival of the fishing rod was not tightened, and the tightening was tightened when it was suddenly stressed.

3. The pole section is too tight, and the stuck phenomenon caused by the foreign body when the fish hook is hung at the bottom of the water for a long time.

2. How to solve the fishing rod festival

You can try the following methods when you encounter a fishing rod card festival:

Method 1:If the fishing rod is stuck, the fishing rod is broken away, removes the card festival, and finds two flat places or stones on the two sections, puts a few thin layers of thin cloth, and holds the stuck two sections tightly with your hands.Hold on the ground or stones _ a few times, pay special attention to_The pole body vertical, the part of the fishing rod will be released.

Method two:Put the stuck fishing rod on the table in two sections, and use a hair dryer to blow repeatedly at the place where the card festival (coarse section). When you feel that the fishing rod card is a bit hot, you can rotate it gently.Unscrew.

Method three:Pour on the rough joints of the stuck part with boiling water, but do not pour it on the details, then dry it and then rotate with two poles to loosen it.

Method 4:Poin the two sections of the fishing rod, the thin part is upward, the thick part is down, and the sewing motor oil (oil, kerosene can be available) drip on the dry Tube wall to let it slowly penetrate, and then the then will be penetrated.Place the fishing rod and wait patiently for a day or two, wrap the card with a cloth, and gently rotate and loosen it with a few times, which can basically be separated.
