棉花播种保苗是一项综合性的技术。棉籽发芽必须具备两个条件,第一,温度要高;第二,土壤水分要足。而我省大部分棉区播种时温度偏低,土壤水分少。因此,只有针对上面这两个问题采取措施,才能保证棉花全苗。朝阳地区大凌河流域棉区广大革命群众,在多年来同干旱斗争中,创造出了一种棉花四犁抗旱播种法,对一次播种保全苗,起到了良好效果。 Cotton sowing seedlings is a comprehensive technology. Cotton germination must have two conditions, first, the temperature is high; second, the soil moisture to be sufficient. Most of our cotton planting temperature is low, less soil moisture. Therefore, we can only guarantee the whole cotton plant if we take measures against the above two problems. In the Daling River Basin in the Chaoyang District, a large number of revolutionary masses in the cotton area in the course of their struggle against drought have created a cotton sowing drought-resistant sowing method that has achieved good results in one sowing of seedlings for preservation.
