摘要
依据大量的实测试验资料,论证了土壤水分对小麦、玉米、棉花生长发育的影响及不同土壤水分与作物产量的关系,分析确定了三种作物高产的适宜土壤水分上、下限指标,为实现高产及节水灌溉提供了依据。
Based on experimental data,the influence of soil moisture upon the growth and yield of wheat,corn and cotton,and the relationship between the yield and different moisture conditions are demonstrated.In addition,the high and low limit of optimum soil moisture indexes for high yield of these crops are presented.
