摘要
提要本文是采用三因素二次回归正交试验方法,研究了灌水量、N肥施量、P肥施量的春小麦产量响应。在连续监测土壤水分变化和作物需水规律基础上,求得—套春小麦节水灌溉制度,供春麦地区节水灌溉使用。
By quadric regression orthogonal experimentation, The influences of irrigation water supply and quantities of nitrogenous and phosphate fertilizers applied upon the yield of winter wheat are studied. On the basis of consecutive monitor of the bluctuations of soil moisture and water need of crops, a set of irrigation procedures for spring wheat are gained.
