为了解决和田地区近几年棉花座果中部少,下部上部稍多。即“中空”问题,我们以水肥为基础改进棉花生长环境,适当增加棉花中部结桃,提高棉花产量。 试验在地区农业科技开发中心研究所进行,土壤属于淡黄沙壤土。播种地土壤有机质含量0.466％。全氮0.0241％,速氮24PPm,≥10℃有效积温4486℃,无霜期最多年
In order to solve the problem of the central part of the cotton field in the Wada area in recent years, the upper part of the lower part is slightly more. That is, “hollow” problem, we improve the cotton growing environment on the basis of water and fertilizer, appropriately increase the peach in the middle of cotton and increase the cotton yield. The experiment was carried out by the Institute of Regional Agricultural Science and Technology Development Center and the soil belonged to light yellow sandy loam. Sowing soil organic matter content of 0.466%. 0.0241% of total nitrogen, 24ppm of fast nitrogen, effective accumulative temperature of 4486 ℃ ≥10 ℃, the most frost-free period
