2013年6月17日晚21:07,新疆生产建设兵团第八师142团25连遭受严重的冰雹灾害,导致30%的棉花砸成光杆,100%的棉花被砸断头。为了给今后灾后管理提供依据,选取受灾一致的地块,分别以拔出光杆和不拔除光杆2种不同处理,在同样管理的情况下,进行产量对比试验。结果查明,拔出光杆和不拔除光杆2种处理的产量分别为233.0 kg/667 m2和289.1 kg/667 m2,前者的效益也没后者高。故在6月中旬棉花遭受冰雹灾害后,建议除加强管理外,不必拔出光杆棉。
On the night of June 17, 2013, at 21:07, the Xinjiang Production and Construction Corps, the 8th Division, the 142th Corps, suffered heavy hail disaster, causing 30% of the cotton to hit the polished rod and 100% of the cotton was smashed. In order to provide the basis for future disaster management, we selected the same parcels affected by the disaster, respectively, with two different treatments of pulling out the polished rod and not removing the polished rod. Under the same management, the yield comparison test was carried out. As a result, it was found that the outputs of the two treatments with and without the polished rod were 233.0 kg / 667 m2 and 289.1 kg / 667 m2 respectively, and the former did not have the higher benefit. Therefore, in mid-June cotton suffered hail disaster, it is recommended that in addition to strengthening management, do not pull out the light pole cotton.
