[Select cotton varieties do not enter the wrong area] Recently, according to Bailizhou Town, Zhijiang City, Hubei Province, Lushan Township, Huarong County, Hunan Province, Zhoutou Township, Susong County, Anhui Province, Furong Town, Pengze County, Jiangxi Province, 2018 In the year of cotton production, most farmers increased their yields compared with the previous year. The benefits were slightly higher than other crops, and the area of ​​cotton fields showed a small recovery. The cotton market in the new year has already started. From the perspective of market dynamics, first, most farmers are looking forward to purchasing hybrid cotton varieties of good quality and high price, especially those with strong scientific and technological awareness. They think that the price is high and the value is high. Second, some only recognize large peach cotton. Kind, think that cotton is equal to high yield; third is to blindly seek early maturing varieties, but I do not know how to support planting; fourth, regardless of the characteristics of the variety, only buy the lowest price of cotton; fifth, some farmers have not yet decided what to buy cotton, see others buy I will buy it and follow the trend.
Choosing a good cotton seed is one of the important factors for high cotton yield. The precise choice can get a good return. For this reason, it is necessary to strictly control the selection of the cotton in the production of cotton.
First of all, we must choose authentic cotton varieties. First, it is necessary to select the varieties approved by the national or provincial agricultural authorities, and avoid counterfeit parallel cotton varieties; second, it is necessary to select varieties with adaptability, stress resistance and high yield; third, new varieties should be tested locally. After the demonstration planting, it will be expanded and promoted to be safe and reliable. Fourth, it is necessary to keep the cotton invoices when purchasing seeds, and find the basis for the claim.
Second, we must learn to identify high-quality varieties. First, it depends on whether the variety is hybrid or conventional. Hybrid varieties generally increase yield by about 15% compared with conventional cotton, because they are worthwhile, high quality and good price. Second, they depend on purity and germination rate. Hybrid cotton has high purity. The yield is high, the germination rate is high, the survival rate is high, the whole seedling can be sown once, the planting area can be enlarged, and the production cost can be reduced; the third is to look at the varieties with strong anti-falling ability and good smear to pick up the flowers, so as to save Labor, lay a good foundation for the machine to pick cotton; Fourth, we must know that the bell (peach) is overweight, the bell (peach) shell is thicker, the clothing is lower, the fiber is short, the yield is low, the quality is poor, and the management needs More fat, good-looking no matter what, not worth the candle. At the present stage, the medium-sized flower single bell (peach) used in production is about 7 grams, and the average bell (peach) weighs about 6 grams. The blind pursuit of the big peach variety will only make mistakes; the fifth is to understand that the low-priced varieties are generally hybrid F2 generations. Varieties or cotton varieties with low germination rate for many years, or multi-generation cotton varieties with conventional cotton varieties, low purity, low germination rate, low yield and lower efficiency.
Third, we must be good at good and good. Even the fine cotton varieties, if there is no good method for planting, the yield is very different. For example, excellent early maturing varieties, if planted too early, because the growth period is 15-20 days less than the mid-late maturity, it is often easy to Premature aging, resulting in reduced production, if the previous glutinous wheat or rapeseed after sowing, can ease the seasons contradiction, but also get wheat (oil) cotton (flower) double harvest. It is the medium and late-maturing cotton varieties. It is also necessary to select the appropriate sowing period according to the length of the ripening period, do a good job of close planting, formula fertilization, chemical regulation, shape the ideal high-yield plant shape, scientifically control pests and diseases, purify the cotton field ecological environment, and save costs. In order to achieve the purpose of increasing production, increasing revenue, and increasing efficiency. A link failure can cause different degrees of loss.
