Key measures for management of cotton boll opening period
During the boll opening period, high-yield cotton looks precocious and does not senescence prematurely, which requires boll opening in the lower part of the plant, continued flowering in the upper part, and few late buds. The robust growth of cotton, the top fruit branch flat extension, fruit branch length of 20 cm 30 cm, there are 3 buds 4.

Cotton bolls rot should be checked and treated on high temperature and humidity days for planting cotton
At present, cotton is in the flowering and boll opening period, which is the vigorous period of cotton reproduction and growth, the key period of peach growth and yield formation, and the key period of preventing and controlling boll rot. The rainfall from late July to early August this year is abnormally more than normal.

Strange phenomenon of cotton: young peaches in the middle and upper parts crack ahead of time
Recently, some farmers called to reflect a strange phenomenon in cotton production: the lower big bolls and early cotton bolls grew normally and did not open bolls, while the tender bolls in the middle and upper parts cracked ahead of time, and some of them rotted bolls after cracking. Wuqiao County Agricultural Bureau immediately organized technicians to go deep into the field to find the reason. First, the field showed that the sowing was too early. In the early cotton fields where there were no buds or few buds in the upper 1 and 3 fruit branches due to Rain Water or diseases and insect pests, the number of cracking of cotton peaches in the middle and upper part was relatively large, that is, the outer bolls of 7 fruit branches and 10 fruit branches were counted from below.

High yield of cotton foliar fertilizer spraying
First, foliar spraying nitrogen to prevent premature senility. When the cotton was nitrogen deficient, the leaves were light yellow, the lower leaves were yellow and withered, the fruit branches were few, the flowers and bolls were sparse, and the cotton yield and quality were affected at the initial stage of boll opening. Fertilizer spraying method: prepare 1% urea solution, spray 100 kg per mu, spray once every 7 to 10 days, continuous spraying.

Nine reminders of cotton management in the later stage
Now cotton has entered the boll opening stage, which is the last growth stage. Throughout September, the upper cotton bolls continued to grow and enrich. There are still more than 50 days left between now and the harvest in late October. If the management is relaxed, it is still possible to suffer heavy losses. (1) ideologically, we should not relax the management in the later stage, especially if we do not think that if there are not too many cotton peaches, we are no longer willing to invest in high yield. If you can keep more than 40,000 cotton peaches per mu and let it grow up and open well, you can harvest four or five hundred jin of seed cotton per mu. I downloaded 6 new cotton varieties under national examination in our province.

Main measures of Field Management of Cotton in the later stage
Cotton generally began to open bolls in late August and early September (the End of Heat to White Dew), cotton management entered the later stage, and the main tasks of cotton field management in the later stage were to protect roots, leaves, promote early maturity and prevent premature senility, so as to achieve the goal of high yield and high quality and high yield and bumper harvest. 1. Timely watering to prevent autumn drought: if the soil moisture is insufficient in the later growth stage of cotton, it will affect the absorption function of the root system, the development of cotton boll is slow, the fiber and seeds can not mature normally, and the soil nutrients can not play a better role. Therefore, in case of autumn drought, it should be timely.

Cotton picking has knowledge, careful picking and high returns.
First, timely cotton picking is the last link of cotton production and the key to ensuring high yield and high efficiency. As cotton is an infinite inflorescence crop, it has budding, flowering, boll setting and maturity, so it needs to be harvested many times. Therefore, according to the cotton boll mature in the cracking process to complete the third stage of fiber development, that is, the fiber dehydration period, about 7 days. The water content of cotton boll shell decreased from 80% to 30%, the water content of cotton pulp decreased from 57% to 18%, and the fiber was further dehydrated and matured.
