What should we pay more attention to to make cotton achieve high yields?

The diseases that occur in cotton before budding are collectively referred to as seedling diseases, because there are fewer leaves before cotton seedlings bud, the root system is not yet developed, in the case of low temperature and rainy climate, the pathogen is very easy to infect cotton seedlings, the light cotton seedlings grow weak water, and the heavy ones cause a large area of dead seedlings. Therefore, the identification and prevention of seedling diseases is the key factor to obtain high cotton yield.

In addition to the selection of disease-resistant varieties, crop rotation and stubble, fine land preparation, and timely sowing during the sowing period, the following measures should be adopted in time at the seedling stage

1.Timely ploughing after rain. In case of rainy weather, after the rainy day, it can be cultivated in time to increase soil permeability and reduce the infection of pathogens.

2.Morning seedlings, seal the soil in time. After the cotton seedlings are seedlings, the seedlings are thinned, and the seedlings are generally left 2 or 3 plants per hole, so that the soil nutrients are concentrated to supply a small number of cotton plants, so that the cotton seedlings grow robustly, and the soil is sealed in time after the seedlings are interspersed to improve the ground temperature and reduce the occurrence of seedling diseases.

3.Chemical control. After the cotton seedlings are ready to sprout, when encountering low temperature, rain or cold snap, the cotton seedlings can be sprayed with chemical agents to prevent the occurrence of large-scale seedling diseases. Generally, 50 carbendazim 800 times solution can be used for pharmaceutical control. (from Nongxintong**).

If you want to have a high yield, the following steps are indispensable for planting cotton!

The first step is to treat the plot, first of all, to use a sufficient amount of base fertilizer, 10-15 kg of urea, 15-20 kg of diammonium phosphate, 15-20 kg of potassium sulfate, and 800-1000 kg of organic fertilizer per mu. Secondly, it is necessary to maintain the moisture of the soil, determine the moisturizing period according to the sowing period, and after the humidity reaches the requirements, timely cultivation, sowing and mulching and insulation.

The second step is to choose the right variety, according to their own plot environment to choose, for the humidity is very fat, it is recommended to choose some cotton varieties with strong growth potential and high yield potential, such as Jifeng 106, etc., the planting density is generally 1500-2000 plants is optimal, the wide row is not less than 1 meter, and the narrow row is not less than 1 meter. For dry land or plots with poor water and fertilizer conditions, you can choose cotton varieties with strong resistance and stable growth, such as Jifeng No. 197, etc., the planting density is generally between 3000-4000 plants, and it is necessary to plant in large and small rows, generally large rows of wide meters, narrow rows of small rows of wide meters.

The third step is timely sowing Using the warming effect of plastic film covering, sowing seeds in advance and in a timely manner can effectively extend the growth period of cotton, which is also the key to improving cotton yield. 1 night before sowing, the seedbed should be watered thoroughly, to the next morning when sowing, gently press the hole with your fingers, put 1 seed in each pot, and then cover the seeds with fine soil, fill the gaps, cover the soil thickness to 1-2 cm is appropriate, after the cover should be sprayed with 300-500 times more carbendazim and other agents in time.

The fourth step is to transplant the seedlings in time after the cotyledons turn green. If transplanted too early, the seedlings are not fully developed and are prone to death; If transplantation is too late, it will affect the growth of cotton seedlings and cause cotton seedlings to bend. When the seeds germinate and take root, the small mounds on the sowing pit need to be cleared in time, so as not to suppress the seedlings and affect the normal growth of cotton seedlings.

The fifth step is topdressing and watering The cotton planted with film develops early, grows fast, bears more peaches, requires a large amount of water and fertilizer, and the peak time of fertilizer and water demand will also be advanced. Cotton does not need to be fertilized at the seedling stage and bud stage, and it is necessary to fertilize more at the flowering and boll stage. The boll setting period of cotton is the peak period of phosphorus demand.

It is recommended to spray phosphorus fertilizer from cotton roots, which has a very significant yield increase effect. Cotton flowering and boll stage is sensitive to water, in order to prevent premature aging, it is necessary to irrigate the early flowering stage, full boll stage and late flowering stage. If there is a lot of rain during the rainy season, we should also do a good job of drainage to prevent waterlogging.

The sixth step is topping, which can effectively control the growth height of cotton and lay a good foundation for the development of cotton bolls. Generally speaking, the peak time of the year is July. Under normal circumstances, you need to keep three nodes in the lower branch and four nodes in the upper branch, and remove vertices in time when the branch reaches the scheduled node.

The above are the steps to grow high-yield cotton, I hope it can help you.

I think the best way is to control the fertilizer and water during the cotton growing season, so that you can achieve high yields.

First choose a good cotton variety, then choose the right soil for planting, and then master the amount of watering and fertilization, so that you can achieve high yields.

What are some tips for making cotton yields higher? Cotton farmers usually value chemical fertilizers, ignore organic fertilizers, value nitrogen fertilizers, ignore potassium fertilizers, look at repeated Hefei, and neglect other trace element fertilizers that are needed. After boll formation, the most suitable time to cover the top fertilizer and leak the first fiber is after hitting the top heart, according to the reasonable formula ratio of scientific fertilizer, the growth of cotton seedlings will become better and better, so it is more important to choose fertilizer when planting.

In recent years, the reduction of cotton production has also exposed many problems in cotton planting. On the one hand, due to the low threshold for the supervision and approval of cotton varieties, the quality of the most advanced varieties in the market is uneven, and cotton farmers buy seeds that do not meet the standards, and cotton production will not go up. In addition, this figure is the cotton field seedling period, cotton high yield needs to pay attention to three points, the first time to sow seeds, Qin Jing must be cultivated around March to sow seeds, the second is the emergence of seedlings, seedlings do not come out must be taken out, there is a saying, money can not buy seedlings, seedlings are the most concerned.

A qualified technician should design different management models according to the weather conditions. For example, when the accumulated temperature is relatively low, it is recommended that farmers choose early-maturing varieties. When the temperature is high, it is recommended that farmers use a high-frequency drip mode.

Planting cotton first of all, we must do a good job of returning to the imitation nutrient bowl seedlings, the nutrient bowl should be used in a 1:3 ratio of ripe farmhouse fertilizer and fine soil, add 1:10 urea water to fully stir and evenly, and it is advisable to pinch into a ball by hand, and plant before and after the Qingming Festival, because early sowing is the primary condition for high yield.

There are many factors that affect cotton yield, and some factors we can't control, such as weather and temperature. However, some planting aspects can still be improved. The first thing to talk about is to choose the land, if you can choose a piece of soil thicker, first of all, you must know that cotton is grown in the first place, our northwest Xinjiang place, the quality of cotton produced is not said, cotton farmers who plant cotton can produce dozens of tons of cotton in a year, and an acre can produce hundreds of kilograms of cotton.

1. Reasonable selection. Second, sowing seedlings Third, the old school of chemical dismantling brother old learning regulation Generally, in order to control the height of fruit branches, promote the growth of root system, and improve the ability of leaf photosynthesis after the seedlings emerge, arthrochlor will be used to cultivate strong seedlings. Fourth, fertilizer and water control, to precise fertilization, according to the expected yield to calculate the amount of fertilizer required.

Fifth, the brigade to lift the top pruning in the fruit branch to 75 cm when the need for topping treatment, the topping is generally completed in early July. 6. Field management in the middle and late stages of cotton is generally managed through water and fertilizer to ensure the normal growth of plants, and to avoid late maturity of plants. Seventh, pest control the use of chemical agents in advance of the prevention of pests and diseases as soon as possible, for some pests can be used biological control methods to ensure that the disease does not spread.

8. Scientific spraying of chemical defoliants. Spraying defoliant is a task that must be carried out before cotton harvesting, which can effectively improve the efficiency of cotton harvesting.

I believe that in order to improve the yield and quality of the state, it is necessary to strengthen the management of various aspects in ordinary life, and it is necessary to strengthen the management of justice by making decisions based on the living environment of cotton, the amount of water and the amount of sunshine in the surrounding area, and this will help to improve the management of the market.

It is necessary to choose better varieties, apply more fertilizer, pay attention to suitable fertilization opportunities, pay attention to ventilation, and pay attention to preventing pests and diseases.

1. Choose the seeds.

2。Proper fertilization. To apply three fertilizers, the principle of three fertilizers: seedling bud fertilizer should be fast, flower bell fertilizer should be heavy, and cover the top of the strong peach fertilizer should be skillful.

Seedling bud fertilizer should be fast: apply enough seedling bud fertilizer before covering the film.

Flower boll fertilizer should be heavy: after cotton enters the flowering period, from early July to early mid-July, after an average of one hard peach per plant, break the membrane and ditch and reapply flower boll fertilizer, apply 12 to 14 kg of urea, 130 to 45 kg of phosphate fertilizer, and 7 to 8 kg of potassium fertilizer per mu.

Cover the top of the strong peach fat should be skillful: it is the key to prevent premature aging, compete for autumn peach, strengthen the peach cover, and win high yield. 8 to 10 days after the beginning of autumn, fertilize according to the long growth of cotton combined with weather conditions.

Apply 4 to 5 kg of urea and 2 to 3 kg of potassium fertilizer per mu. Combined with insect control, spraying foliar fertilizer, protecting leaves and increasing boll and hail weight.

3. Do a good job in water drainage and irrigation and water management. Cotton has a long growth period, large branches and leaves, a large transpiration coefficient, and more water. The water requirement is less at the seedling stage, and the water requirement at the bud stage gradually increases, and the water requirement is the most at the full flowering stage, and it decreases day by day after spitting.

4. Cotton harvesting. It is required to pick in time after a batch of cotton bolls are fully cracked and spit out.

Communicate with neighbors to share planting experience, the original neighbors used drip irrigation technology under the film, saving land and facilitating the management of dust demolition, improving the efficiency of land use, saving costs, increasing income, and achieving a bumper harvest.

1. Save land and facilitate management.

The application of drip irrigation technology under film in the actual cotton planting process can effectively avoid the installation of a large number of irrigation equipment, resulting in land occupation. Generally, 5% to 7% of arable land can be saved. In addition, the implementation of drip irrigation under film can also improve the growth environment of crops to a certain extent.

In the actual implementation process, drip irrigation under the film can be adjusted by the control of the valve, which also plays a very important role. Promote the emancipation of the entire plantation owner labor force. In summary, the advantages of drip irrigation under film are very significant.

It can maximize the effect of automatic irrigation, effectively reduce various labor intensity, and increase cotton yield.

2. Improve the efficiency of saline-alkali land use.

Large-scale planting of cotton in saline-alkali land and the use of drip irrigation under film can effectively improve the irrigation quality of cotton and minimize the salt transfer in saline-alkali land. Through the implementation of drip irrigation technology under film, a desalination zone conducive to cotton growth can be gradually formed in cotton fields, so as to improve the comprehensive utilization efficiency of saline-alkali land.

3. Save fertilizers, resist pests and diseases, and resist disasters and provide disaster relief.

The application of drip irrigation under film in cotton planting can not only effectively preserve fertility, but also improve the drought resistance and disease resistance of cotton. The implementation of drip irrigation under the film ensures that the water flow reaches the roots of the crop directly. In the actual fertilization process, the fertilizer can be transported to the roots of cotton through the equipment, improve the absorption capacity and effect of cotton on various fertilizers, and the implementation of drip irrigation technology under cotton film can also fertilize cotton in time.

In the actual implementation of drip irrigation under the film, the use of pipeline transportation can greatly reduce the invasion of various pests and diseases on the cotton root system and improve the growth quality of crops.

The above is an analysis of the advantages of using sprinkler irrigation technology in the process of cotton planting, which can also be used in your own planting practice to promote cost reduction and jujube harvest.

It should be to control the temperature between 10 degrees and 20 degrees, and then you can water and fertilize more, so that the pipe socks may be high-yielding, and you should also pay attention to pruning the branches and leaves, and spray some pesticides in time.

Drought is uniform, timely prevention and drainage of drought, cotton flowering and boll setting stage must be watered in time, with water to adjust the fertilizer or promote the decomposition of fertilizer and the root system of nutrients absorption. The rainy season is generally from July to August, but over the years, the climate has been relatively large, and periodic droughts often occur, requiring timely watering to achieve high yields.

In addition to the need for more nitrogen, phosphorus and potassium fertilizers in the life of cotton, trace elements such as manganese, boron, zinc and sulfur are also needed, and the ratio of nitrogen, phosphorus and potassium is 3:1:3, but with the improvement of production level and soil fertility level, the proportion of the three elements will change in different regions and different natural parts.

Now the ratio of some cavities is adjusted to 8:3:6

Whether it is planting cotton or other crops, it needs to be cultivated according to the living habits and growth conditions of the crop, as long as it is managed and cared for according to its living habits, it is possible to achieve high yields.

When planting, we must choose the land with relatively fertile soil, and we must use farmhouse fertilizer when fertilizing, never use fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time. I think that if we can do a good job in these aspects, we will definitely be able to grow Changzhi and bring good cotton.

Seed drying and selection Seeds are generally dried 15 days before sowing. Drying seeds can break the dormant state of cotton seeds, effectively kill the epidermal pathogens of cotton seeds, reduce the diseases of jujube rock at the light seedling stage, promote seed ripening, enhance seed water absorption and seed coat air permeability, improve seed germination rate and germination potential, and promote seed germination. Delint coated seeds to strip in low-light weather.

2.Pesticide seed dressing Pesticide seed dressing, can be filial piety to kill the germs carried by the seeds and the germs in the surrounding soil after sowing, so as to improve the seedling rate, prevent and control seedling diseases, with the use of insecticide Qiaoyan containing seeds, can also reduce the harm of seedling pests. Seed dressing agent, containing a certain amount of fungicides, insecticides and an appropriate amount of plant growth regulators.

Commonly used agents and.
