According to reports, since April 20, with the invasion of cold air and extreme late spring cold, snowfall, low temperature, and freezing weather have occurred in the cotton planting areas of northern Xinjiang, which has had a greater impact on cotton production. At the end of sowing in Xinjiang, seedlings have emerged in early-sown cotton fields, and most cotton fields are in the stage of seed emergence.
Farmers and cooperatives in Changji, Fukang, Kuitun, Shihezi and other places reported that cotton seedlings were frozen to death in some plots, and soil compaction also caused cotton seedlings to germinate and break ground. difficulty. Some major cotton-growing counties and townships such as Kashgar and Aksu in southern Xinjiang have also encountered strong winds, dust, and cooling weather. The mulch film has been blown up, and cotton seedlings have been dried up and died by strong winds. The weather in April was one of the important factors for Zheng Cotton’s sharp rebound last week, and there were obvious signs of capital speculation and price increases.
Will the recent extreme weather have a big impact on cotton production in Xinjiang? The author believes that the impact is small and within the controllable range. Judging from the cotton sowing start period in 2021, both southern and northern Xinjiang are a bit early (since 2019, hand-picked cotton has started sowing in Hotan, Kashgar, Bachu and other places in late March, and most machine-picked cotton in northern Xinjiang has started sowing around mid-April. , obviously earlier this year), so from the perspective of season and accumulated temperature, farmers still have relatively sufficient time to replant and replant even if they encounter extreme weather such as rainfall, cooling, and strong winds. From the perspective of technology and maturity period, replanting around the end of April will have limited impact on cotton yields.
Furthermore, the weather in Xinjiang’s cotton areas is changeable from April to May, from warm to cold. Farmers and agricultural technology departments have accumulated rich experience in disaster prevention and reduction, such as Sustained low temperatures can be dealt with through various methods such as advance cultivation, field fumigation, and auxin spraying. At present, various departments and cotton farmers are speeding up the progress of spring sowing on the one hand, and on the other hand, they are making every effort to fight against disasters and protect seedlings. Farmers in Aksu, Korla and other places believe that water, fertilizer and management have kept up with the situation from May to August, and the accumulated temperature has returned to normal levels, so the impact of the current disaster can be basically ignored.
Finally, for cotton fields that have been severely damaged by frost damage or strong winds, or where low temperatures have caused cotton seeds to fail to germinate or break ground, if you want to replant before the end of April or mid-May, you can choose “New Judging from the yields of the Luzao series varieties in the past two years, if field management is in place and the weather cooperates, there is not a big gap between the yields of the Luzao varieties and the Xinluzhong varieties. </p
