High-efficient balanced fertilization for good quality and high yield of wheat-corn,vegetables in Henan Province
【摘要】 介绍农作物高产优质施肥技术的田间试验研究情况。田间试验结果表明:小麦在氮磷肥配施时(N270kg/hm2、P2O5120kg/hm2),K2O最佳用量为180kg/hm2,小麦最高产量达6880kg/hm2;玉米在氮磷肥配施时(N225kg/hm2、P2O5120kg/hm2),K2O最佳用量为180kg/hm2,玉米最高产量达7640kg/hm2;萝卜在氮磷肥配施时(N300kg/hm2、P2O5225kg/hm2),K2O最佳用量为300kg/hm2,萝卜最高产量达79860kg/hm2;白菜在氮磷肥配施时(N300kg/hm2、P2O5225kg/hm2),K2O最佳用量为300kg/hm2,白菜最高产量达95050kg/hm2。
【Abstract】 By field trial on wheat,it is found that when nitrogen and phosphate fertilizer are applied together(270 kg N/hm2 and 120 kg P2O5/hm2),the optimal potassium fertilizer is 180 kg K2O/hm2 and the best wheat yield is 6 880 kg/hm2.On maize,225 kg N/hm2 and 120 kg P2O5/hm2 together,the optimal potassium fertilizer is 180 kg K2O/hm2 and the best maize yield is 7 640 kg/hm2.On radish,300 kg N/hm2 and 225 kg P2O5/hm2 together,the optimal potassium fertilizer is 300 kg K2O/hm2 and the best radish yield is 79 860 kg/hm2.On cabbage,300 kg N/hm2 and 225 kg P2O5/hm2 together,the optimal potassium fertilizer is 300 kg K2O/hm2 and the best radish yield is 95 050 kg/hm2.
