犁地前,施磷酸二铵15~20kg/667m2;尿素5~8kg/667m2;钾肥0~3kg/667m2;锌肥1~1.5kg/667m2;并带种肥磷酸二铵5kg/667m2。保苗数:基本苗5500~6000株,有效株数5200~5800株。滴灌指标:根据土壤质地及地力的差异,地亩玉米全生育期一般需要滴水6~8次,每次滴水量35~45m3/667m2总定额为350~370m3/667m2。1苗期管理
Before plowing, apply DAP 15 ~ 20kg / 667m2; Urea 5 ~ 8kg / 667m2; Potassium 0 ~ 3kg / 667m2; Zinc fertilizer 1 ~ 1.5kg / 667m2; and take fertilizer DAP 5kg / 667m2. Seedling number: 5500 ~ 6000 basic seedlings, the effective number of 5200 ~ 5800 strains. Drip Irrigation Index: According to the difference of soil texture and soil fertility, the total growth period of acreage maize generally needs to be dripped 6 to 8 times. The total amount of drip irrigation 35 ~ 45m3 / 667m2 is 350 ~ 370m3 / 667m2. Seedling management
