衡水地区光、热资源丰富,利于发展棉花生产,但干旱缺水。平均年降雨量531.8毫米,春季占全年降雨量的10%,夏季占70%。雨量偏少,而且季节分配不匀。地下水资源贫乏,利用率较低,地表水、地下水可利用资源总计10.83亿立米,每亩耕地平均占有水量27立米。近年来过量开采,地下水位急剧下降。由于水资源严重不足,以致50%以上耕地无水可浇或只能浇极少量的水。因此,旱地棉田的抗旱播种,抗旱保苗是增产
Hengshui region light and heat rich in resources, which will benefit the development of cotton production, but drought and water shortage. The average annual rainfall is 531.8 mm, accounting for 10% of the annual rainfall in spring and 70% in summer. Slightly less rainfall, and uneven season distribution. The groundwater resource is poor and the utilization rate is low. The total available resources of surface water and groundwater are 1.083 billion cubic meters and the average water occupation per acre is 27 cubic meters. Over-exploitation in recent years, groundwater level dropped sharply. Due to the serious shortage of water resources, over 50% of cultivated land can be poured without water or with only a very small amount of water. Therefore, drought-resistant cotton fields planted cotton, drought seedlings is to increase production
