Teach you how to produce high cotton yield

According to the survey and analysis of cotton production in recent years, a set of cultivation management models suitable for the cotton area was summarized, namely: April seedlings, May buds, June flowers, picked flowers at the end of July, meticulous management in August, tenderness in September, Autumn peach cover the top, at the end of October Teng.

April seedlings. It is required that the soil moisture content of the cultivated layer is more than 15%. No matter whether the cultivation of mulching film, planting in the open field or artificial water-feeding, no matter whether the sowing date will be sooner or later, or the seedling transplanting, etc., it must be fully obtained before the end of April. The number of varieties per mu is 2000~2300, the general variety is 2500~2800, the number of small plant types is 3000~3500, and there are no diseases or insect pests. The red and green stems account for about 50% respectively, and the plants have more than 2 pieces. True leaf.

May Lei. On the basis of grasping the whole seedlings and obtaining strong seedlings, we should topically apply 3–5 kg of pure nitrogen to the abundance of the base fertilizer and the seedlings, and perform small-scale water irrigation for the soil moisture, and timely cultivating the soil in a timely manner. Soil conservation, to promote the healthy growth of cotton seedlings. At the same time, once every 7 to 10 days, spray 400 times rich potassium, more than 2 times in a row, and add insecticide (cotton blind locust, cotton locust, etc.) sterilization (wilting, leaf spot, etc.) agent to prevent pests and diseases. More than 80% of plants began to bud before the end of May.

June flowers. This month is not only a busy period for the “three summers” but also a critical period for the rapid growth of cotton. In the specific application, the key is to do a good job spray fertilizer (400 times rich million potassium plus 1% urea plus 0.2% Sonic boron, etc.) spraying (insecticide fungicides) work, once every 7 to 10 days, and even spray 2~3 Times. And for the flexible and flexible management of cotton plant growth, when the daily increase of up to 3 cm above, combined with spray fertilizer (medicine) mu control with a pure 2 grams of dilute amine once, with 0.1 acres of zinc sulfate and 0.2% of the speed of music Boron plays a role in resisting heat, promotes sitting and blossoming into peaches, and reduces the shedding of buds, so that 40%-50% of the cotton plants see open flowers before the end of the month.

July Baole Bell. The end of July is the critical period for vegetative and reproductive growth of cotton, and it is also the critical period for the transformation of carbon and nitrogen in the body and the demand for various biological enzymes and trace elements. Focus on prevention and control of pests and diseases, timely (overcoming the traditional practice of the 6th month of the lunar calendar and the wrong practice of long-term and low-play). (The number of large plant species per plant is 15-17, medium-sized varieties are 13-15, small On the basis of 12 to 13 plant-type varieties, about 10 to 12 kg of urea was used for the growth of the cotton field on July 10 (13 in the Zhuangshao field, and in the weak plant), and 13 to 15 kg in diammonium. Potassium chloride 15 kg, both to meet the needs of the development of buds, flowers, and bells, but also can effectively prevent the formation of abscisic acid in cotton plants, to prevent premature declining due to defertilization. At the same time, appropriate removal of some groups of tips for cotton plants is based on the principle that cotton fields can be seen within 20 to 23 July. Otherwise, the ground may be too weak or the plant spacing may be too narrow, or the plant spacing may be too narrow (or earlier). Excessive nitrogen fertilizer is not conducive to the formation of buds, flowers, and bells, and it also easily leads to shedding of a large number of budding bells. In addition, it is best to water in the “three volts” days at night, especially in well irrigation areas where the temperature difference between groundwater and cotton fields is large (above 30° C.). After irrigation, a large number of buds and bells can easily fall off. Canal water should also be irrigated after 4 pm and before 10 am. At the same time the upper part of the ground continues to spray 400 times richer potassium 1 or 2 times, the effect is better.
