甘肃省制约小麦单产提高的主要因素是河西缺水,河东等地干旱。节约用水,增加保灌面积和增强抗旱能力,提高现有耕地小麦的单产,尤其旱地小麦产量是当务之急。为解决这一问题,甘肃省农业部门针对旱地小麦产量低而不稳的问题,在总结传统地膜小麦播种穴与幼苗错位、出苗率低、人工放苗劳动强度大、一次覆膜只种植
The main factors restricting the improvement of wheat yield in Gansu Province are the lack of water in Hexi and the drought in Hedong and other places. Saving water, increasing the area for irrigation and water conservation and increasing drought resistance will increase the yield of existing arable land wheat, especially the dry land wheat output. To solve this problem, the agricultural sector in Gansu Province in response to the problem of low and unstable wheat yield in dryland, summing up the traditional mulching wheat seed sowing and seedling dislocation, the emergence rate is low, the labor intensity of artificial seedling, a film only planting
