Why should cotton drip less in the later stage?

Overview:Because in the later stage, sufficient moisture will cause vigorous growth, resulting in flower and fruit drop.

Explanation:There is a saying: "The doll that can't die when it cries, the cotton that doesn't die when it dries". It means: it doesn't matter if the child cries for a while, and don't be afraid of the drought in cotton.

Cotton in the later stage, into the reproductive growth stage, if the water is too sufficient, it is easy to lead to excessive vegetative growth, that is: water fertilizer, growth is not coordinated, resulting in falling flowers and fruits, therefore, cotton in the later stage should try not drip irrigation.

Cotton is a drought-tolerant but waterlog-sensitive crop. The water requirements of cotton are different at different growth stages, and the requirements for suitable soil water content are also different.

The law of cotton water demand is as follows: during the growth and development of cotton, the soil water content of cotton field should be kept at about 60% of the maximum water holding capacity in the field, and the average water demand of cotton in a lifetime is 200 300 cubic mu. Cotton is irrigated in the field to ensure the normal growth and development of cotton and prevent yield reduction due to drought.

First, the water consumption at the seedling stage accounts for less than 15% of the total water consumption, and the daily water consumption intensity is square mu, and the moderate water shortage is conducive to promoting root rooting and drought resistance in the later stage. Second, after budding, water consumption accounts for 12% 20%, the daily water consumption intensity is square acres, three weeks after the bud to flowering is the critical period of cotton water (full bud stage - early flowering stage), at this time the root production rate reaches the maximum (below 80 cm); The third is the flowering boll stage, water consumption accounts for 45% 65%, the daily water consumption intensity is square acres, the early flowering is the moisture sensitive period of cotton, and the lack of water will lead to bud and flower shedding. Water deficit after the boll stage had little effect on yield, but it would affect the fiber length and micronaire value of young boll. Fourth, after spitting, the daily water consumption is reduced to less than 2 square mu, and the water consumption accounts for 10% to 20%.

It is drought tolerant in the later stage and does not need to be watered a lot.

Summary. Generally speaking, after heavy rain on cotton sowing, there is no need for dripping. This is because heavy rain itself is a large amount of surface water dripping, which will nourish the soil of cotton and distribute the water in the soil evenly, thus providing sufficient water for the cotton plants to grow and develop.

In addition, heavy rain is better after fertilization, it can not only wash the fertilizer and nutrients on the soil to the depth of the cotton root system, so that the cotton can be absorbed normally, but also can improve the soil moisture of the cotton root system, improve the stress resistance of the plant, and prevent the reduction of cotton harvest due to death. Therefore, after the heavy rain is planted on the cotton sowing, there is no longer a need for dripping.

In addition, heavy rain is better after fertilization, it can not only wash the fertilizer and nutrients on the soil to the depth of the cotton root system, so that the cotton can be absorbed normally, but also can improve the soil moisture of the cotton celery flower root system, improve the stress resistance of the plant, and prevent the reduction of cotton harvest due to death.

Therefore, after the heavy rain is planted on the cotton sowing, there is no longer a need for dripping water.

The key is whether the rain has alkali to produce good seedlings.

Since cotton cultivation requires a lot of water, and rain is a favorable cause, it can be said that rain helps cotton to produce good seedlings. But the effect of rain also depends on the pure annihilation of the rainfall and replanting situation, if the rainfall is too large, it will make the cotton soil too wet, which is harmful, will cause the phenomenon of cotton seedlings deflated, affect the emergence of cotton seedlings. In addition, it is also necessary to consider the change of atmospheric temperature, if the temperature is too high, the rain is easily polluted by ultraviolet radiation, which will directly affect the growth of cotton seedlings.

In short, before cotton seedlings emerge, it is necessary to control the water source of rain keys and the atmospheric temperature to ensure the healthy growth of cotton seedlings.

I am afraid of dripping water and rotten seeds.

Occasional rain has little effect.

If the rain is heavy, can there be good seedlings?

If the rainfall is too heavy, it will make the cotton soil too wet, which is harmful, which will cause the phenomenon of cotton seedlings deflating and affect the emergence of cotton seedlings.

Then there is no need to drip anymore?

No. Is it time to wait for the seedlings to emerge and then re-water?

Cotton does not need to wait for seedlings to emerge before rewatering, but can be sprinkled before the seeds are sprinkled under the finger wheel. When sprinkling, it is advisable to be moist and not over-immersed, and generally do not exceed 10 hours before sprinkling once. After the emergence of seedlings, if the soil is dry, you can carry out irrigation to change the water to keep the soil moist.

Summary. Cotton bud stage generally does not need watering, but the flower boll stage requires a lot of water, during this period of cotton is neither drought resistance, nor waterlogging resistance, in case of drought watering yield increase significantly, if there is drought or flooding, can cause a large number of buds to fall off, so we must pay close attention to the drought and flood situation of cotton fields. If it does not rain for about 10 days, the cotton field should be watered once, and the watering must not be delayed due to the illusion of dampness on the ground.

Furrow irrigation should be used for watering. In case of heavy rain, the stagnant water in the field should be discharged in time. In order to ensure the normal growth of cotton plants and achieve the purpose of high quality and high yield.

Is there a problem with cotton sowing ten days without dripping water?

Hello, cotton sowing in the ground for ten days without dripping no problem.

I'm afraid the seeds are bad.

Then you pour less, not too much.

Cotton bud stage generally does not need to be watered, but the flower boll period requires a lot of water, during this period of cotton is neither drought resistant, nor waterlogging, in case of drought watering to increase the world stove yield significantly, if there is drought or flooding, can cause a large number of buds to fall off, so we must pay close attention to the drought and flood situation of cotton fields. If it does not rain for about 10 days, the cotton field should be watered once, and the watering must not be delayed due to the illusion of dampness on the ground. Furrow irrigation should be used for watering.

In case of heavy rain, the stagnant water in the field should be discharged in time. In order to ensure the normal growth of cotton plants, to achieve the purpose of high quality and high yield.

Can't drain water. When will it be available?

The day after tomorrow, it has been planted for ten days.

I don't have a big impression of seeds.

It's okay, it's not. It's okay, it's not big.

Water it the day after tomorrow, don't water too much.

Summary. Hello, the impact is relatively large. The wetness of the soil varies depending on the amount of drip water.

When the amount of water is small, the distribution of water in the soil is "V" shaped, and the water is mostly distributed in the upper part of the cultivated layer, which has little effect on seedling emergence. However, due to the fact that the water is mainly in the upper part and the bottom moisture is insufficient, the cotton root system is shallow, and the drought resistance is poor, and the water can not be stopped after the emergence of seedlings.

During the growth cycle of cotton, how much does the addition or subtraction of dripping water affect cotton?

Hello, the impact is relatively large. The wetness of the soil is different for different drip trillion consumption. When the amount of water is small, the distribution of water in the soil is "V" shaped, and the water in the section is mostly distributed in the upper part of the cultivated layer, which has little effect on the emergence of seedlings.

However, due to the fact that the water is mainly in the upper part and the bottom moisture is insufficient, the cotton root system is shallow and the drought resistance is poor, and the water can not be stopped after the seedlings emerge.

The distribution of water in the soil is "U" shaped, and the water is distributed in the entire cultivated layer in the scattered circle.

A small amount of water dripping water in the temperature has not risen and then give the cotton seedlings a low temperature, high humidity to take the disturbance of the environment, the effect of the seed coating agent has passed, the occurrence of rotten root disease will aggravate the rolling, is not conducive to the growth of cotton seedlings.

During the cotton growth cycle, the dripping water and alkali are not traced, and how much impact does it have on cotton.

Hello dear, thank you for waiting for the mess, let me explain to you, the results show that the results show that the alkaline soil conditioner is used in the drip irrigation cotton field where there is no heavier saline-alkali Qingyuan in the newly reclaimed land, which has a certain impact on the emergence of cotton and its growth, appearance, yield, etc., the plant height increases by 5 10 cm, the average number of boll per plant increases, the average boll weight increases g, the yield of seed cotton kg hm2 is increased, and the yield is increased; At the same time, it can reduce soil salinity, and the total salinity can be reduced by one percent.

Summary. 2. The amount of drip water is appropriate, and the seedling water should not be greedy.

2. The amount of drip water is appropriate, and the seedling water should not be greedy.

The narrow row is expanded from 10cm to 12 13cm, and the wide row is reduced from 66cm to 63 64cm, which is convenient for laying drip irrigation belt without affecting machine picking. At the same time, the drip irrigation base belt is laid from one film, 2 tubes, and 2 drip irrigation belts are laid separately, and the pants are laid in the middle of the two wide rows on the membrane to a film with 3 tubes and 3 drip irrigation belts are laid in the middle of the three narrow rows on the membrane to ensure uniform dripping and balanced pressure. The dripper spacing and drip hole spacing of drip irrigation belt were different due to soil texture, and the drip hole spacing of sandy loam drip irrigation belt was 300mm, and the dripper flow rate was hourly. The drip hole spacing of the clay drip irrigation belt is 300 mm, and the dripper flow rate is square hours.

Summary. Hello, can drip water.

Cotton seeds germinate and need to absorb more than 60% of the weight of the seeds. That is to say, the soil moisture is not enough cotton seeds can not germinate, usually in order to ensure the normal emergence of cotton, the soil moisture content should reach 18 20%, or 70 80% of the field water holding. Of course, the soil moisture should not be too much, after the soil moisture is too much, the oxygen is insufficient, and it is easy to rot the seeds.

Can cotton drip if the seedlings are uneven for more than ten days after sowing the cotton.

Hello, can drip water. Cotton seeds germinate and need to absorb more than 60% of the weight of the seeds. That is to say, the soil moisture is not enough cotton seeds are disturbed and cannot germinate, usually in order to protect the branches and hunger to prove the normal emergence of cotton seedlings, the soil moisture content should reach 18 20%, or 70 80% of the water holding capacity in the field.

Of course, the soil moisture should not be too much, after the soil moisture is too much, the oxygen is insufficient, and it is easy to rot the seeds.

Hello, cotton seeds need enough oxygen to germinate, but the minimum germination temperature of cotton seeds is required to be nuclear punch.
