Storage of wet cotton
1. Seed cotton should be stored in the warehouse and the warehouse should be dry. Lay clean and dry bricks on the ground, leaving a certain gap between bricks and bricks, with a width of not less than 20 cm, to ensure air circulation; bricks covered with bamboo mats or reeds, and then stacked with cotton. two。 Cotton picked back, do not dry directly on the ground, should be laid on the bamboo bed or set up bamboo curtains to dry, the drying speed is fast, and will not be mixed with three wires. When cotton can make a crisp click when it is exposed to the cottonseed bite with teeth, the water content of seed cotton is generally about 7.5%, which can satisfy the length.

High quality cultivation techniques of Color Ecological Cotton
Caoxian Special Economic Animal and Plant Research Institute of Shandong Province has achieved high economic benefits by introducing green, brown and other natural ecological cotton. Has been rapidly promoted in the local area. In order to obtain high yield and high quality of colored cotton, the following field management should be done well in the later stage. 1. Watering autumn water, spraying and protecting bolls have significant effects on preventing premature senescence of cotton, reducing shedding of cotton bolls, increasing boll weight, improving seed maturity and fiber quality. The specific method is to adopt small trenches to irrigate the root water and spray the whole plant with cotton boll protector at the same time. two。 Fine pruning, reduction

Eight requirements that should be paid attention to in the application of cotton film precision sowing machine
In 2005, our regiment introduced a 2BMJ-12 cotton film precision sowing machine produced by Shihezi Agricultural Machinery Research Institute, which was planted on a trial basis of 30 hectares in that year. The application of precision-on-demand technology on cotton film saves the cost of seed and manual seedling determination, and has the advantages of simple mechanical debugging operation, stable performance, uniform and neat growth of cotton seedlings after sowing. Below, eight requirements that should be paid attention to when using the machine are introduced as follows. First, the requirements for the quality of land ploughing is suitable for ploughing, with a ploughing depth of 28cm to 30cm and the same ploughing depth.

Take targeted measures to strengthen the management of cotton in the middle and later stage
This year, cotton is affected by unfavorable weather such as low temperature, overcast and rain, lack of sunshine, etc., and a large area of plants grow weakly and develop late. In addition, natural disasters such as recent torrential rains and typhoons occur frequently, so the situation of cotton production is very grim. At present, cotton is in a critical period of growth, and various localities should take targeted technical measures to strengthen the management of cotton fields, promote the transformation of seedling conditions, and strive to achieve a bumper cotton harvest. 1. Fertilizer operation. Focus on the application of top fertilizer and mixed spraying of drug fertilizer in the later stage, generally applying urea 5-7.5 kg per mu to increase boll weight and prevent premature senility. The bell is late and medium.

Study on the efficiency of Cotton Light Table in different planting patterns
In order to further increase the cotton yield, it is difficult to increase the number of plants per unit area. In production, it is necessary to increase the density, improve the poor ventilation and light transmittance in the middle and lower part of the cotton population, and improve the light transmittance and photosynthetic efficiency in the middle and lower part of the cotton population. In this paper, through the study of cotton population photosynthetic efficiency and light transmittance of different planting patterns, in order to determine the reasonable cotton population structure in specific areas, and to provide a basis for high-yield and high-quality cotton cultivation. Materials and methods 1. The general situation of the test was conducted in 2002-2003.

We should pay attention to spraying cotton in adverse weather.
When spraying pesticides on cotton to control diseases and insect pests, it will often affect the spraying quality, reduce the control effect and even cause drug damage due to adverse weather. In view of this situation, the author in the production practice according to different weather changes, take the following measures to achieve a better control effect. In windy and windy days, spraying cotton plants received unevenly, which affected the control effect. In view of this situation, pesticide varieties with strong internal absorption and permeability can be selected. The spray head should be closer to the cotton plant when spraying, so as to prevent the damage caused by the spray blown away by the wind.
