复合肥不仅有省工、省力与施用方便之优点,而且有提高水稻、油菜作物的产量与品质,以及提高肥料养分元素利用率的作用。从复合肥增产作用来看,关键是靠肥料当季利用率的提高;从复合肥产品来看关键是靠其NPK等养分元素含量的配方合理性;复合肥产品应用效果的大小关键是以颗粒状加工剂型为最佳。因地制宣地开展区域性、作物专用性和生育期专用性的应用和研究。
Fertilizer not only has the advantages of labor-saving, labor-saving and convenient application, but also improves the yield and quality of rice and rapeseed crops and enhances the utilization of fertilizer nutrient elements. From the role of fertilizer production, the key is to rely on seasonal fertilizer utilization rate; from the point of view of the compound fertilizer product is its NPK and other nutrients rationality of formula; the effect of compound fertilizer product size is the key particle Form processing formulations for the best. Because of the system of land declared to carry out regional, crop-specific and growth-specific application and research.
