Matters needing attention in Regional Test of Cotton varieties (Lines)
The regional comparison test of cotton varieties (lines) is to compare the newly introduced local varieties (lines) with the main local varieties to identify their characteristics of early maturity (growth period), high quality, high yield and resistance to diseases and insect pests, as well as economic characters and fiber quality. The main purpose of this paper is to identify the performance of the tested varieties (lines) in each cotton area, so as to provide a scientific basis for the selection of excellent varieties in each cotton area. First, the selected experimental site should be representative and consistent. It is required that the land is flat, the fertility is medium and uniform, the previous crop is consistent, the irrigation and drainage is convenient, the location of the experimental plot is suitable, and the light is light.

Key points of Cotton yield formation period Management
The light and heat conditions in the early part of this year are favorable for the growth of cotton, but the recent low temperature and light, overcast and rainy weather are extremely disadvantageous to the growth of cotton, and the shedding of buds and bolls increases obviously. At present, it is a critical period for the formation of cotton yield. in order to obtain high cotton yield, the following management measures should be strengthened: first, to apply topping fertilizer and foliar spraying fertilizer for cotton fields with more bolls and premature senescence, urea 5-7.5 kg per 667 square meters, foliar fertilizer can also be applied in combination with pest control. Second, reasonable pruning and chemical control due to recent Rain Water

2019 New cotton varieties: high-yielding cotton seeds, a new high-yield insect-resistant cotton variety has been cultivated in Anhui.
The Cotton Research Institute of the Chinese Academy of Agricultural Sciences recently developed a new cotton variety (Zhongmiansuo 53) in Hefei that can increase production by 20%. It can produce more than 50 peaches per plant and yield 751 jin of seed cotton per mu, twice as much as ordinary cotton, and has stronger insect resistance. At present, China Cotton Institute 53 has been listed as a subsidized variety of cotton in Anhui Province in 2007. At the same time, Zhongmiansuo 53 is also a bivalent transgenic insect-resistant cotton.

Prevention and Rescue measures of three Major Drug damage to Cotton
1. Strict operation and effective prevention. When using all kinds of drugs mentioned above, cotton must be used rationally in accordance with the operation rules (including drug type, concentration, method and time, etc.), so that it can not only give full play to its efficacy, but also reduce the cost and prevent drug damage. 2. Timely "rescue" and eliminate "dangerous situation". After the occurrence of drug damage, a large amount of water can be sprayed on the leaves for leaching, and irrigation, drainage and washing medicine can be used in the soil, or safety agents can be used to neutralize and detoxify. If Bordeaux solution is misused, it can be sprayed with 0.5%-1% lime milk due to drug damage caused by copper ions.
