棉花在花铃期经常发生自然灾害,如雹灾、旱灾、风灾、虫灾等,致使棉花产量下降。为了准确估测棉花花铃期受害产量补偿能力,减少灾害所造成的损失。本试验以泽普县主栽品种中棉所49号为材料进行研究,模拟棉花不同损害程度所具有的产量补偿能力,为抗灾夺丰收提供科学依据。一、材料与方法1.试验材料本试验于2012年在泽普县古勒巴格乡2村进行。试验地土质为沙壤土,肥力中等,供试品种为中棉所49号,前茬棉花。2.试验方法该试验于2012年4月25日播种,采用(60+30)厘米宽窄行种植,地膜覆盖,田间管理同大田。
Cotton often occurs during the flower and natural disasters, such as hail, drought, wind disaster, pest disaster, resulting in decreased cotton production. In order to accurately estimate the yield-compensating ability of cotton during the flower-boll stage and reduce the losses caused by disasters. In this experiment, the main cultivar Zhongmianshu No. 49 in Zepu County was used as material to simulate the yield compensation ability of cotton with different degrees of damage and provide a scientific basis for harvesting in the disaster-stricken area. I. Materials and Methods 1. Test Materials The test was conducted in 2012 in 2 villages of Gule Ba Ge, Ze Pu County. Soil test for the sandy loam soil, medium fertility, the test varieties for the Cotai No. 49, the former crop of cotton. 2. Test Method The test was sown on April 25, 2012, using (60 + 30) cm wide and narrow row planting, mulching, field management with the field.
