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 seedbed base fertilizer.
At present, there are no ploughing and reserved cotton rows in many cotton fields, and the preparation work lags behind. The fields that are ready to transplant cotton seedlings are full of rape or @ # @ 245 cotton seedlings, so the time for applying base fertilizer is tight. The top priority is to pay close attention to the reserved cotton line, apply base fertilizer after rape and wheat harvest, and apply high content compound fertilizer 30-40 kg per mu.
The weight of cotton seedling topdressing is in the light speed cotton seedling stage, the nutrition body is small, the root system is young, and the amount of topdressing fertilizer should not be too large, otherwise reverse osmosis will occur, which will reverse the water flow of cotton seedlings and inhibit the growth and development of cotton seedlings. Rotten alkene dung water or dilute urea solution should be applied on the seedbed, and Huimanfeng and other active liquid fertilizer should be applied at the same time. The cotton seedlings transplanted in the field will be treated with urea after the new leaves are unfolded, with a dosage of no more than 5 kg per mu.

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.

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
