1. What are the inorganic Fertilizers

Inorganic Fertilizer is also known as "Chemical Fertilizer".Fertilizers composed of inorganic matter.It mainly includes single -quality Fertilizers and composite Fertilizers such as nitrogen fertilizer, phosphorus Fertilizer, Potassium fertilizer, and trace element Fertilizers.

1. nitrogen fertilizer

Inorganic Fertilizer contains nitrogen fertilizer, of which nitrogen Fertilizers contain ammonia, ammonium bicarbonate, ammonium chloride, ammonium sulfate and other Fertilizers. Ammonia water has a strong smell and has strong corrosiveness in the soil.The production of vegetables is increased, and ammonium chloride can inhibit the nitrification of rice fields and can make rice form fiber.

2. Phosphorus Fertilizer

Inorganic Fertilizer mainly includes phosphorus Fertilizer. Among them, the more common ones are calcium phosphate, phosphate powder, calcium and magnesium phosphate Fertilizer, etc. The phosphorus Fertilizer developed after using sulfate to decompose phosphate mines.There are two types of colors: gray and brown, which is suitable for use in acidic soil as base Fertilizers.

3. Potassium fertilizer

Inorganic Fertilizer mainly includes potassium Fertilizers, mainly including potassium chloride, potassium sulfate, plant ash, potassium diarrhea salt, and perple phosphate (potassium dihydrogen phosphate).Most of them can be dissolved in water, and the Fertilizer effect is fast.It can be absorbed by the soil and is not easy to lose.When applying an appropriate amount of potassium Fertilizers, the stems of the crop can grow strong, prevent falling, promote blooming and strong, and enhance the ability of drought resistance, cold, and disease -resistant pests.

4. Compound fertilizer

Inorganic Fertilizer contains compound Fertilizers, which are common potassium dihydrogen phosphate, ammonium phosphate, ammonium ammonium, potassium nitrate, etc. Potassium dihydrogen phosphate is often used as high -efficiency nitrogen phosphate Compound fertilizer.The shape is granules or powder, which is suitable for soil with a pH of 7.5.

5. Trace element Fertilizer

Inorganic Fertilizers include trace element Fertilizers, and more common ones are copper Fertilizer, boron Fertilizer, molybdenum Fertilizer, zinc Fertilizer, manganese Fertilizer, etc. The trace element Fertilizer plays an important role in the growth and development of plants.At the same time, the growth of crops is accelerated.

2. The difference between Organic fertilizer and inorganic Fertilizers

1. Different sources

Organic fertilizerThe raw materials are rotten animal and plant corpses, animal feces, and animal hair, etc.Including human dung, Fertilizer, compost, green Fertilizer, cake Fertilizer, biogas Fertilizer, etc.People also call it "green Fertilizer" or "farmhouse Fertilizer". Its source is relatively wide, which is relatively easy to collect.

Increasing Fertilizer refers to Fertilizers produced by chemical synthesis, including nitrogen, phosphorus, potassium, and Compound fertilizer.

2. Different effects

The ingredients of Organic fertilizer are relatively complicated, and it is not easy to master its dosage. It often leads to excess nutrition in some places, and there are some places to remove Fertilizer.After the use of organic Fertilizers, its decomposition speed is relatively slow, so it is relatively late, but the fertility is eased and lasting.The amount of Organic fertilizer is large and the operation is tedious, which is why many farmers' friends are unwilling to use it.

Inorganic Fertilizer, its visibility is relatively fast, the ingredients are pure, easy to grasp the amount, it saves effort and time, and it is very convenient for transportation and storage. However, its cost is not comprehensive.Excessive dosage will pollute water resources.

3. The impact on the land is different

The nutritional elements contained in organic Fertilizers are mostly organic. It is difficult to use crops directly. It must slowly release a variety of nutrient elements through microorganisms in order to supply nutrients.

When using inorganic Fertilizer, be sure not to do too much, because too much use of inorganic Fertilizer will imbalance the nutritional components of the soil, make the phenomenon of the land of the land more serious, and the minerals containing will also be accelerated, so that the soil will be even moreBarren, resulting in low productivity of the land.It is best to cooperate with each other, mainly Organic fertilizer, and inorganic Fertilizer as aid. This can not only improve the growth rate of crops and improve the growth environment.

1. What are the use of sea poles

1. Open it by sectionSea pole, Align the coils, and on a straight line, the connections of each section should be slightly tightened.Cross coils should be a quasi -winding wheel card.

2. The baying wheel, the winding wheels will be on the card seat, fix it to death with a nut,

Dial the winding wheel to the reverse position, pull the wire head, pull out the fishing line, and then pass through the coil one by one until passing through the tip of the pole.Then use the connecting ring to hang the aconite and bomb bait to prepare for throwing.

3. Dial the inverse switch back to the positive rotation position and adjust the drainage device, which is very important.Too tight, the resistance of the qualifying is too large, and it is easy to break the line when encountering a big fish; too loose, the line resistance is too small, and the line is too fast when encountering the big fish.Usually pull the fishing line by hand, you can pull the fishing line.

4. Rotate the rotation wheels to make the bait ball from the tip of the pole 30 ~ 40 cm.Then hold the pole at the rod of the rim, and the middle finger and the ring finger are sandwiched to the back of the wire. The first joint of the index finger hooks the fishing line and flip the line ring.

5. After the aconite falls into the water, immediately remove the circular ring and shake the wound wheel handle to close the line. When the closing line is retracted, the fishing line is still relaxed, and the sea pole is placed on the bracket.It should be larger than the ground), that is, it should be steep.Generally speaking, the greater the elevation angle, the higher the sensitivity; otherwise, the slower.It is the right standard to judge whether the elevation angle is suitable for the angle between the Fishing rods and the fishing line. When the angle is closer to 90 , the more sensitive the response.Therefore, this angle is the core of the response sensitivity.After the sea pole was supported, a small bell was then pinched on the tip of the pole.

6. If you encounter heavy winds, the corners will make the fishing rod easily influenced by the wind.In order to enhance the anti -wind resistance capacity, the elevation angle can be reduced, but it cannot be too small, which will reduce the sensitivity of the pole tip. In addition, the sea pole can be recovered several sections, which can reduce the pole to the high and reduce the impact of the wind;Or lie on the side of the sea pole on the shore, but pay attention to the angle between the fishing rod and the fishing line, so that it is close to 90

7. After the sea pole is supported, you can see the reaction, or listen to the ring, or look at the tip of the pole.When you see the sharp swing or ringtone, you can turn a loser to raise the pole after holding the pole, and then quickly close the line. After receiving a few meters line, you have to raise it once again.fish lips.

8. After the bait enters the water, there is still no response after 20 ~ 30 minutes. At this time, you should start and change the bait.Because the bait will spread out shortly after entering the water. After half an hour, the bait will be eaten by small fish, and it will take time in vain without changing the bait.

2. What are the precautions for the use of sea poles

1. Do not forget to turn on the line when throwing.The adverse consequences caused by the implementation of the throwing action without opening the online file are obvious.Some bomb hooks have become "Sky Girls Sanhua", and some are broken and broken.

2. Do not stay for too long.The drooping line refers to the distance from the section of the pass from the tip of the sea pole to the bomb hook.The drooping line is generally about 30 cm. Too long down the line will seriously restrict the throwing movement of the sea pole.Weeds and the like.Therefore, even if the hooks and bomb hooks are used together at the same time, it must not exceed 40 cm.

3. Do not twist the fishing line wheel too tightly.Turn it too tightly and let go of it.The drainage of the fishing line wheel is twisted too tightly, and when the fish is hooked, there will be a danger of Fishing rods.

4. Don't meet people and fish prematurely or copy the fish prematurely.Early, the big fish pulled the big fish near the shore and exposed the water, and the fish would struggle desperately. At this time, the struggle would be much greater than when it was hooked.The correct approach should be to harvest the wires, repeatedly catfish, until the big fish belly turns white and copied fish into the net.But be careful not to get fish in the waters of the barrier.

5. When choosing a fishing position, try to avoid weeds, peanuts, branches and the like in front of this waters, because these obstacles will affect your catfish.

6. Do not buckle from top to bottom when copying fish, because there are still hooks and wires in the fish mouth, copy from top to bottom, no matter how to copy the fish.The correct way should be the left hand holding the rod, the right hand holding the net, and the direction of the left hand, and the right hand sinks the net under the big fish in a timely manner.When the left hand is walked to the net port and sinking the fish head, at this time, the right hand holding the net is quickly copied and copied the big fish into the net.

3. How should the sea pole be maintained

1. If there is a sea rod with a bottom cover, open the back cover and pull out all the sea rods. Don't pull too tightly.Dry or dry in a ventilated place.

2. The sea pole without the back cover is pulled out of three -quarters of each section. Put it in a ventilated place to dry or dry, so that the water evaporates from the gap between the two sections.Dry.

3. If it is rainy weather, the humidity in the air is very large, which is not conducive to the evaporation of water.You can pull out half of the sea rod and heat it flat on the electric Mattress to evaporate the moisture.

4. When the sea pole falls in the sea, it is necessary to fully wash it with water in time, and then dry it, because the seawater is more corrosive to the fishing rod.The wheels must also be cleaned with water, because the seawater is more corrosive to metal.

1. Outdoor folding knife or straight knife

1. The advantages and disadvantages of straight knives

The knife, as the name suggests, is a knife that will not be folded.Therefore, the straight knife is different from the folding knife. It does not have a connection point, and the handle is integrated with the blade.It is for this reason that the straight knife is much stronger than the folding knife, especially the whole keel's straight knife.

The connection point on the folding knife greatly weakens the solid of the Tool.The sturdy straight knife can be used for Outdoor tasks such as knocking, fire, leverage, hammering.However, in terms of carrying, the straight knife has the advantage of folding knives.Straight knife requires a strong and reliable scabbard to store tools.Another disadvantage of a straight knife is that they are heavier than folding knives.

2. The advantages and disadvantages of folding knife

The blade of the folding knife can be folded into the handle so that the folding knife can be carried in the pocket.This method reduces the size of the Tool and hides a sharp blade.However, the main axis link point in the folding knife also has disadvantages. When the pressure applied is too large, it may break.That is, why can't you use the folding knife for any reason in the wild.

The main advantage of the folding knife is that it is easy to carry and use comprehensive use.However, if it is Outdoor survival, it is not recommended to use a folding knife.Because the folding knife is not strong enough and reliable, it cannot become the main survival Tool.

Therefore, for daily use, a small fold is good.For Outdoor use, remember to use a straight knife, straight knife is always a safer and stronger choice.

2. How to choose Outdoor survival knives

1. Size selection

A straight knife suitable for Outdoor survival should be 10-15 cm in length.The size of the Outdoor knife should not be too large.The too long knife will lead to the overall weight of the knife. It takes physical strength to take it in the hand and occupy the space in the bag. It is not flexible and laborious to use. It is not conducive to long -distance Outdoor survival adventures.Not too small.Although the palm knife is easy to carry, it is not very useful.Cutting branches and cutting ropes are more laborious. It is easy to break accidentally, and it is very ribs.In comparison, medium -length knives can do some relatively fine tasks, but also be competent for some heavy tasks.

2, knife type selection

A whole keel's straight knife is the best choice for Outdoor knives.The knife of the folding knife can be folded into the handle, which is more safe and easy to carry.But this biggest advantage is the biggest disadvantage for Outdoor survival use.As we all know, as long as it is stitching, it will be more likely to cause damage.The folding knife's hollow handle and folding shaft are obviously weak parts that are easy to break.There is no integrated knife body for activity components, which is obviously more suitable for Outdoor survival.The straight knife of the keels is better resistant, can withstand greater use intensity, the overall force is more balanced, and it can withstand high -intensity use.

3. Blade selection

It is best to choose a bladeless blade.Although there is a jagged blade, although it looks very cool, this design is very bad for Outdoor knives.Although the tooth blade can help a little on the cutting rope, but in addition, this design is very "dragging the legs": if the tooth blade is blunt, you need to use a specific grinding Tool to polish, one groove, and a groove.It is very troublesome; at the same time, the Outdoor knife with a tooth blade has also been greatly reduced, because the tooth blade cannot do anything else except cutting the rope.

4. Handle selection

For the choice of the handle, remember two words: non -slip, comfortable.The anti -skid of the Outdoor knife handle is very important. This allows you no matter what kind of environment you are, you don't have to worry about the sword on your hand suddenly slipped away.As for the grip comfort of the handle, you can only try to try the feel when choosing a Tool.

5. Material selection

Compared with other materials, Damascus Steel's knife is rigid and soft, and the blade is better.

1. The difference between table tennis shoes and running shoes

The difference between table tennis shoes and running shoes lies in functionality, sole thickness and weight.

1. Functional:table tennis shoes are specially designed for table tennis. They have professional functions for table tennis. Its design will focus on providing the ability to start and stop rapidly. The running shoes are mainly to face the feet when Running.Impact, therefore emphasizes buffer and stability.

2,The thickness and weight of the sole:The soles of table tennis shoes are thinner and the weight is lighter. This is to provide a better foot feeling and a faster response. The soles of running shoes are thicker to provide sufficient buffer and may be heavier.

2. Can running shoes be worn as table tennis shoes?

1. Due to design differences, wearing running shoes for table tennis will affect the players.First of all, due to the lack of polyurethane materials, it is difficult to provide players with sufficient grip, which is easy to slide in the game, which affects the player's movement and response speed.In addition, the bottom of the Running shoe is relatively wide, and it is not suitable for the fast steering and curved movements required for table tennis, which will affect the player's operating experience.

2. running shoes are different from the structure and function of table tennis shoes. Wearing running shoes can easily increase the risk of injury when playing.First of all, due to the thicker buffer of running shoes, the distance between the players' feet and the soles of the shoe is far away, which can easily cause unstable feelings and increase the risk of sprains or sliding.Secondly, the toe of the running shoes is wider than the table tennis shoes, which can easily cause the ball table or other players, causing accidental injuries.

Can table tennis shoes be used for Running?

Although table tennis shoes and running shoes are sports shoes, table tennis shoes cannot completely replace running shoes for Running.Due to the different material and effects of the soles and effects of table tennis shoes and running shoes, the grip of table tennis shoes is relatively strong, and its soles are relatively hard. It cannot provide sufficient support and cushioning effects, which can easily lead to injuries to the foot.In addition, if you use table tennis shoes for Running, the shoes are easily worn out faster, affecting the service life.

table tennis shoes and running shoes are designed to adapt to specific occasions and exercise methods. The two are completely different, so you should choose according to the actual situation when choosing a sports shoes.Do not use it for different sports because of the shape of the shoes.If you often run Running activities, it is recommended to choose a professional running shoes so that you can better protect your feet health.If you often play table tennis, then a pair of professional table tennis shoes is important.
