配方施肥是一项科学性强的施肥技术。它按照系统工程学的原理和观点,把各项分散的、单项的农业技术措施组装起来,在肥料方面具体表现在改革施肥技术,以提高综合性科学技术措施的经济效益。配方施肥不仅要解决化肥定量的问题,而且要定肥,所以探讨各地区不同作物上不同化肥品种的肥效及增产效益已十分必要。农民的经验和我们的实践都证明,进口磷酸二铵(或复合肥料)及三料过磷酸钙在配方施肥中增产效果明
Formula fertilization is a scientific fertilization technology. In accordance with the principles and perspectives of systems engineering, it assembles all the scattered and individual agricultural technical measures, and concretely shows the reform of fertilization technology in terms of fertilizer in order to improve the economic benefits of comprehensive scientific and technological measures. Formula fertilization not only to solve the problem of quantitative fertilizers, but also to set fertilizer, so explore the different crops in different regions of different fertilizer efficiency and yield of fertilizer has become very necessary. The experience of farmers and our practice have proved that the import of diammonium phosphate (or compound fertilizer) and three superphosphate in the formula fertilizer yield increase effect
