Today's cotton planting must not only achieve high yields, but also achieve stable production, high quality, and low consumption, and strive to have a certain scale in order to obtain greater, more stable returns. At this stage, we must use the two "helpers" to fully play their role.
One is the machine. The machine can not only replace a large number of labor, reduce the cost of investment, but also improve the operating efficiency, so that it does not violate the agricultural time; it can improve the quality of operations. In the past, traditional mechanical operations were mainly used for soil preparation and sowing, and now they have been developed into precision machine sowing (saving large quantities of seedlings and seedlings), placing seedlings and sealing soil, cultivating, topdressing, earthing, spraying, chemical ripening, and smashing of cotton stalks. Mechanical cotton harvesting is also being actively tested in the Yellow River Basin and has shown promising prospects.
All machines that can use the machine must be machined. The agricultural machinery used for tractors will be continuously updated to continuously improve the quality of machinery operations and expand the scope of machinery operations. As far as possible, small pieces of cotton fields should be combined into large pieces to remove the obstacles between the fields and between the fields, creating favorable conditions for cotton field operations during the growing season. With the increase in the number of acres of cotton planted, medium-horsepower tractors should be used instead of small-horsepower tractors to raise the racks and provide opportunities for cotton farming in the middle and late stages. Even if the tractor hits some cotton plants in the field, it is more than lost.
The second is shrinking security. At present, the best chemical control drugs in cotton are still shrinking. With this helper, you can artificially shape the plant shape, reduce plant height, shorten the internodes, shrink the leaves, control the vegetative growth of the cotton plants, and concentrate the nutrients for flowering and ringing, which not only saves nutrients, but also keeps the cotton fields airy and transparent. Increase cotton harvest index. According to expert experiments, the use of the contracted Anke Muzizi about 25 kg, an increase of 8% -10%.
The three major nutrients that we usually call cotton production are nitrogen, phosphorus and potassium. However, shrinkage does not include nitrogen, phosphorus and potassium. Why can we increase cotton production?
In fact, nitrogen, phosphorus and potassium account for only a small part of the cotton harvest, most of which are composed of carbohydrates and their composites. The initial carbohydrate is synthesized from carbon dioxide and water from the leaves under sunlight, which is photosynthesis. Carbon dioxide, water, and sunlight are the more important nutrients for crops. And these three elements are provided free of charge by nature. The mystery of the increase in production in the shrinkage zone lies in the fact that the upper, middle and lower leaves of the cotton plant can receive the sunlight better and utilize the light energy more fully for photosynthesis to form more photosynthetic products.
In addition, the use of chemical control drugs on cotton can be used to reduce the artificial pruning, artificial topping, etc., to a certain extent, is a high input-output ratio of the stimulation technology. Therefore, to grow cotton, it is necessary to learn this skill.
