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。
Rice, corn and sugarcane belong to gramineous crops and have similar characteristics of nitrogen, phosphorus and potassium nutrition requirements. The application of special compound fertilizer developed according to the characteristics of its nutritional needs can meet and adapt to the needs of nitrogen, phosphorus and potassium nutrition for crop growth and development. Test results: Compared with imported compound fertilizer and common compound fertilizer, the yield of rice increased by 7.67% and 11.50%, that of corn increased by 7.48% and 16.31% and that of sugarcane increased by 5.04 % And 8.28% respectively; rice yield per hm2 increased by 775.60 yuan and 916.20 yuan; corn increased by 758.80 yuan and 1270.40 yuan; sugarcane increased by 931.44 yuan and 1087.02 yuan; and crop quality improved at the same time.
