摘　　要：水稻、玉米、甘蔗同属禾本科作物,对氮、磷、钾营养的需求特点基本相似。施用根据其营养需求特点研制的专用复混肥,能满足和适应作物生长发育对氮、磷、钾营养的需要。试验结果:在施用等量氮、磷、钾养分条件下,专用复混肥与进口复合肥、通用复混肥比较,水稻增产7.67%和11.50%,玉米增产7.48%和16.31%,甘蔗增产5.04%和8.28%;每hm2水稻增收775.60元和916.20元,玉米增收758.80元和1270.40元,甘蔗增收931.44元和1087.02元;同时作物产品品质得以改善提高。The requirements for nutrients N, P and K in grass family crops of rice, maize and sug, arcane are nearly the same. A mix -fertilizer made in terms of the crops＇ demand could meet their nutrient needs of N, P and K. The result showed that in the same quantity of total N,P and K, compared with imported and common mix -fertilizers,application of the special mix -fertilizer could raise the rice yield by 7. 67% and 11. 50%, maize yield by 7. 48% and 16.31% and sugarcane yield by 5. 04% and 8. 28%, respectively. Those were equal to 775.6 yuan and 916.2 yuan for rice, 758.8 yuan and 1270.4 yuan for maize, 931.44 yuan and 1087 yuan for sugarcane per hectare, respectively. Meanwhile, the products＇ quality could be improved.
