测土配方施肥较常规施肥能够提高肥料农学效率,单位施肥量对于产量的贡献明显提高。其中尿素、重过磷酸钙、氯化钾、NPK的肥料农学效率值分别提高27.8%,19.2%,2.3%,33%;肥料偏生产力值提高22.4%;测土配方完全施肥区较常规施肥区产量增加785kg/hm2,提高9.9%。 Compared with conventional fertilization by soil testing and fertilizer, the agronomic efficiency of fertilizers can be increased, and the contribution of unit fertilization to the yield increased obviously. The agronomic efficiency of fertilizers such as urea, SSP, KCl and NPK increased by 27.8%, 19.2%, 2.3% and 33%, respectively. Fertilizer partial productivity increased by 22.4% Output increased 785kg / hm2, an increase of 9.9%.
