Spraying fertilizer on cotton is good for increasing yield and less diseases and insect pests.
Spraying nitrogen fertilizer: urea can destroy the chitin of insects. When cotton aphids (especially aphids) occur, the mixture of urea, washing powder and water in the proportion of 4 ∶ 1 ∶ 400 is sprayed, which has obvious killing effect. Spraying phosphate fertilizer: during the occurrence period of adult cotton bollworm, 1%-2% superphosphate leaching solution as foliar fertilizer can turn oxalic acid into calcium oxalate and lose its attraction to cotton bollworm. The duration of each phosphorus spray is generally 2-3 days. Spraying potash: 10kg of plant ash, 50kg of water, soaking

Spraying "seven liquids" on cotton increases production by 100 jin.
According to the experiments of our Institute of Agricultural Sciences and cotton farmers for many years, spraying the following nutrient solution during the application of insecticides to control insects in different growth stages of cotton can effectively increase the yield by 20% Mel 30%. The methods are introduced as follows: 1. Chicken manure: take 3 kg of fermented dried chicken manure, 2, add 7.5 kg of water, 3, soak for 30 hours, 4, cook 2 more for 5 and 3 hours, 6, filter out the residue, 7, and then ferment, 8, until the liquid surface appears white mold. 9, filter out the mildew, 10, add 50 kg of water, 11, spray evenly in 1 mu of cotton field. 12. Rabbit feces:

It is suitable for cotton to apply fertilizer skillfully to prevent disease and increase yield in the later stage.
In the later stage of cotton growth, the nutrient absorption capacity of cotton root decreased obviously, but if nitrogen, phosphorus, potassium, zinc, boron and other fertilizers were sprayed on cotton leaves, it could prevent premature senescence, promote early maturity, prevent disease, prevent boll falling and bear big peach. It has a significant effect on increasing production. 1. Applying nitrogen fertilizer to prevent premature senility with 1% urea solution 75 Mu 100kg per mu, spraying once every 5 Mill 7 days for 3 consecutive times, can enhance the photosynthesis of leaves, prevent premature senility and increase yield. 2. Applying phosphate fertilizer to promote precocious cotton foliar spraying in the later stage.

Cotton drip Irrigation Automation Project helps to increase Cotton production
The "cotton drip irrigation automatic control science and technology demonstration project" in Shihezi, which has been listed in the state plan, will add another 15000 mu to the experimental demonstration area this year on the basis of last year. In recent years, after the application of cotton drip irrigation under plastic film in Shihezi reclamation area, the total yield and per unit yield of cotton have been greatly increased. * * Tianye Group, as the largest agricultural water-saving drip irrigation equipment manufacturer in China, has promoted water-saving drip irrigation area of more than 10 million mu. In order to seize the commanding heights of science and technology, the company independently innovated and developed cotton drip irrigation automation in 2005.

Scientific use of chemical control cotton can increase production
Scientific chemical control of cotton is an important scientific measure to increase cotton yield. Chemical control technology has three advantages: first, it is conducive to the early development of strong seedlings, controlling high and stable growth, and making it easy to give play to the advantages of increasing production; the second is to simplify cotton field management, save labor and cost; and third, to promote the transformation of second and third types of cotton seedlings, balanced development, increase production and increase efficiency. The principle of chemical control is "a small number of times, light control and frequent adjustment". It should be mastered "control over and over again" or "control at intervals" (flexible control according to soil fertility, rainfall and growth), preferably "once".

Topdressing of cotton at flowering and boll stage
At present, cotton fields are entering the flowering period one after another, and after that, cotton will enter the flowering and boll period of more than 50 days, which is the peak period of cotton fertilizer demand. Cotton blossoms and sets bolls continuously during the flowering and boll period of more than 50 days, and the demand for nutrients is continuous and uninterrupted, so in addition to particularly fertile soil, it must be supplemented by topdressing. Topdressing at flowering and boll stage is an important event in cotton management at flowering and boll stage. 1. Fertilizer deficient plots should increase the amount of topdressing in areas with more per capita cotton planting area, and some villages still maintain a state of low input and low output.

Do you still need topdressing when cotton flowers bloom to the top?
In early August, we went to some concentrated cotton-producing areas and found that some cotton had bloomed to the top of the cotton plant, and the color of the main stem of cotton was also red to the top. The farmer asked: can this kind of cotton still be fertilized? In the face of such questions, the specific situation should be analyzed concretely. Generally speaking, the cotton blossoms to the top in early August, and the cotton stalk is red to the top, indicating that the cotton plant itself is malnourished. Either the lack of fertilizer supply in the cotton field leads to the de-fertilization of cotton, and the vegetative growth and reproductive growth are inhibited; or the fertilizer has been applied and the cotton plant has not been absorbed; or it is early nutrition.

The Beginning of Autumn should pay more attention to the extra-root topdressing of cotton.
Extra-root topdressing of cotton is commonly known as foliar spraying, that is, spraying fertilizer solution on the stems and leaves of cotton plants to make the stems and leaves absorb nutrients and achieve the purpose of nourishing the whole plant (including root system). It has the advantages of saving fertilizer, quick effect and not limited by soil conditions. it is an important yield-increasing measure to quickly supplement nutrients to cotton plants in the late growth stage of cotton, especially after ldquo; the Beginning of Autumn & rdquo;. Why do you say so? Many studies have shown that the nutrients absorbed by leaves can operate in the body as well as those absorbed by roots.

Correct fertilization and strong seedlings of Cotton at Seedling stage
Correct fertilization should be applied in the process of cotton sowing and transplanting to ensure that the seedlings are whole, full and strong. Nursery bed base fertilizer and appropriate amount of cotton seedling plant is small, the need for nutrients is not much, the amount of seedbed base fertilizer should not be too much, emphasizing fine and appropriate amount. Organic fertilizer should be fully mature and weed rhizomes should be removed. For those who choose bio-organic fertilizer, the amount of seedling bed shall not exceed 5 kg per 10 square meters, and the amount of compound fertilizer shall not exceed 1 kg. The feces and urine of rotten acquaintances were applied 20 days in advance, ploughed and mixed with the soil after fertilization. Urea can not be used as seedlings.

Reform of cotton planting mode combined with autumn sowing production
In recent years, in order to promote the high yield of cotton, the Ministry of Agriculture has carried out activities to create a high yield of 10,000 mu of cotton in the main cotton producing provinces throughout the country. Recently, I have investigated the high-yield cotton fields in Hubei, Anhui, Jiangsu, Jiangxi and other provinces. Previous investigations have been conducted in the high-yield cotton fields in Hunan and Zhejiang provinces. The goal of creating high-yield cotton is roughly the same, but the planting patterns are not the same and the planting methods are different. Cotton yield is composed of planting density, number of peaches per plant, boll weight and lint percentage, in which planting density is closely related to cotton yield, while planting density
