Evaluation of Xinjiang Cotton Agricultural Meteorological Conditions in 2021
During the cotton growth and development period in 2021, the thermal conditions in most cotton areas in Xinjiang were better than normal and worse than last year. The average number of cotton bolls per mu in southern and northern Xinjiang cotton areas was more than normal and less than last year. The overall cotton growth situation in most cotton areas of Xinjiang is worse than last year. Among them: the weather process in most of Xinjiang from sowing to emergence is frequent, which is not conducive to early sowing and emergence of cotton; the meteorological conditions in most cotton areas during the seedling period are better than normal and slightly worse than last year, but sandstorms, cooling, and extreme rainfall during the period have adverse effects on the growth of seedlings. Unfavorable; during the budding period, the temperature in most cotton areas of Xinjiang was high, but in late June, the temperature in the northern Xinjiang cotton area was abnormally low, and the growth and development process of cotton was slow; during the flowering and bolling period, most cotton areas had high temperatures, sufficient light, and many high-temperature days. It lasts all year round and lasts for a long time, which is unfavorable for cotton flowering, pollination and boll setting; during the boll-breaking and fluffing period, the temperature in most cotton areas in Xinjiang is high and then low, with less precipitation, which is more beneficial to cotton harvesting and drying in most cotton areas. , but the early first frost and the wind, rain, frost, and cooling weather in early October are unfavorable to the defoliation effect of machine-picked cotton in some cotton areas and the cotton bolls opening. The main meteorological disasters during the cotton growth period include hail, strong winds, low temperatures, local heavy rains and floods, etc. The total disaster losses were higher than last year.
