In late August, the three major cotton areas of Korla, Aksu and Kashgar in southern Xinjiang entered the peach-bearing and cotton-bursting period. Some cotton seed companies, county and township agricultural departments and ginning plants went to the fields to measure production and estimate the 2020 /The open scale purchase price of seed cotton in 2021, considering that the probability of long-term rainfall, low temperature or early frost period in the main cotton-producing areas in early and mid-September is not high, so the accuracy of measuring the yield should reach 70-80%.
Cotton farmers, cotton processing companies and competent agricultural departments predict an increase in output in June and July. In this measurement, the yield per unit area in southern Xinjiang is flat or even slightly decreased (except for the Korla cotton area). Among them, Kashgar and Aksu The seed cotton yield per unit area in the cotton area may remain at 350-400 kg/mu. The proportion of high-yield fields with a unit yield of 450 kg/mu or more has decreased significantly compared with the previous test yields, and the proportion of fields with a unit yield of 300 kg/mu and below has increased.
Why have yield expectations in some cotton areas in southern Xinjiang declined since August? Farmers and cotton processing companies analyzed and summarized the following points: First, in late July, most cotton areas in southern Xinjiang continued to face the test of high temperature and low humidity, and the drought worsened. Some cotton fields were not replenished with water and topdressing in time, resulting in blooming in unsuitable cotton areas. The shedding phenomenon has slowed down the development of cotton bolls; secondly, the COVID-19 epidemic broke out in Xinjiang in mid-to-late July, and various states have comprehensively upgraded their prevention and control, and cotton field management has been affected to a certain extent; thirdly, under the epidemic prevention and control, the transportation and supply of agricultural materials have also been affected. Temporary effects. The supply of water, fertilizer, foliar nutrients and even pesticides such as nitrogen, phosphorus and potassium in some remote areas of Kashgar and Aksu was once very tight; fourth, according to the Central Meteorological Bureau and the Autonomous Region Meteorological Observatory, from the night of August 25 to the night of August 28, the southern Kashgar area, Aksu area, There has been significant precipitation in Bazhou and other places, and the temperature has dropped significantly in most of Xinjiang. Coupled with the strong windy weather in the eastern part of the South Xinjiang Basin, it is not conducive to the growth of flower bolls, cracking of bolls, and catkins. Farmers and relevant agricultural departments need to be more vigilant. </p
