Cotton chemical control is fastidious.
In recent years, with the widespread application of insect-resistant cotton, plastic film mulching and chemical control technology, cotton farmers have some bad cultivation tendency in cotton cultivation technology, especially in chemical control technology (hereinafter referred to as chemical control). If we do not pay attention to timely and appropriate chemical control, the cotton field will grow excessively, the vegetative growth is too prosperous, and the buds, flowers and bolls fall off seriously, which eventually leads to the formation of high, large and empty cotton plants, and serious lodging in the later stage of wind and rain, resulting in great losses. In chemical control, we should aim to stabilize the shelf of high yield, increase buds and protect bolls, and master the "look at the sky, the earth and the seedlings".

Grasp the time and methods of chemical control of cotton
Although the sowing of cotton is late, the development of cotton seedlings is also late. By the first ten days of June, the well-growing cotton fields in the north have now had 7 to 8 true leaves, and some have already budded. Around June 10, most cotton fields will enter the budding stage one after another. On June 10, most cotton fields have three fruit branches, but this year there will be two less fruit branches, and there will be no peaches or fewer peaches, which is not necessarily a bad thing. It can save the work of removing early buds and 1 or 2 fruit branches in the lower part, which is conducive to reducing rotten bolls and stiff bolls. According to the results of the cotton plant survey in Guoxin, the cotton owner is from June 10 to July 10.

Cotton chemical control technology
Cotton chemical control is the use of chemical control means to shape cotton into an ideal plant type and create a population with high light efficiency. 1. Chemical control status and function of cotton is a typical light-loving crop. High yield, early maturity and high quality of cotton in the precocious cotton area of eastern Hebei need to be realized by reasonable close planting, but reasonable close planting will inevitably aggravate the contradiction in the utilization of space and light energy between individuals and groups in the middle and later stage. Therefore, cotton chemical control has become an important supporting measure for reasonable close planting, and it is also the core content of promoting early stress resistance, especially simplifying the cultivation technology system. At present, Ketamine is used in cotton chemical control.

The time of corn chemical control, what medicine should be used?
The time of corn chemical control: the time of using exuberant is the 8-10 leaf stage of corn, that is, the early jointing stage of corn. The kinds of chemical control agents commonly used in corn are corn fortifier, ethephon, metoprolol, trimethoprim, paclobutrazol, ammonia fat and so on.

Scientific Chemical Control Technology of Cotton
Cotton chemical control is the most difficult technology for cotton farmers to master. According to the research of relevant departments, cotton chemical control can affect 30% of cotton production, but most cotton farmers are blindly chemical control, so it is very necessary to promote a simple and easy-to-understand cotton chemical control technology. The experience accumulated over the years is introduced as follows. The following is only the reference data of TM cotton pruning in Switzerland, and cotton farmers should use it flexibly according to soil fertility, climate and actual growth. 7-10 days after topping (around July 25): use 40 milliliters of water per mu 15

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".

Application techniques of different Chemical Control agents in Cotton
Cotton chemical control is the use of chemical control means to shape cotton into an ideal plant type and create a population with high light efficiency, which can make the plant grow healthily, reduce the occurrence of diseases and insect pests, improve cotton yield and improve cotton quality. However, there are many chemical control agents at present, and the correct use technology should be adopted according to different agents in order to achieve better results. First, propranolol. At present, thalidomide is widely used in cotton chemical control, and the effect is ideal. It can reduce the plant height of cotton, reduce the number of fruit branches, promote the transfer of photosynthesis to reproductive growth, and reduce cotton bolls.
