我县历年四、五月份低温阴雨多,棉田土壤易板结,通气性差,病虫害多,与棉花苗期所需要的环境条件有很大矛盾。为了尽量满足棉种发芽出土和棉苗对温度、水分、空气养分和光照的要求,广大棉农在两熟棉田的播种实践中创造了“三高播种”的经验。大面积生产实践证明,“三高播种”对提高播种质量,促进棉苗早、全、齐、壮和夏粮丰收都有良好效果。
My county over the calendar year in May and May, cold and rainy, cotton easy to board knot, poor ventilation, pests and diseases, and the cotton seedling required environmental conditions are very contradictory. In order to try to meet the germination of cotton seed germination and cotton seedlings on the temperature, moisture, air nutrients and light requirements, the majority of farmers in the two cotton fields in the practice of sowing to create a “three high sowing” experience. Large-scale production practice has proved that the “three high sowing” to improve the quality of sowing, cotton seedlings to promote early, all, Qi, Zhuang and summer grain harvest have good results.
