| 摘 要： | 为提高水稻施肥效益，定制合理的肥料施用配方，进行了测土配方施肥与常规施肥试验。结果表明测土配方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28．1％，82．4％，44．7％，48．8％；肥料偏生产力值提高37．0％；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％。

| Abstract: | In order to increase the economic benefits of rice, to establish rational fertilizer application formulation, soil testing and formula fertilization and conventional fertilization were tested. The results showed that soil testing and formula fertilization can increase agronomic efficiency of fertilizer, the contribution of fertilizer for increasing yield was obviously. The urea, triple super phosphate, potassium chloride, N-PK fertilizer agronomy efficiency increased 28. 1%, 82. 4%, 44. 7%, 48. 8% respec- tively; fertilizer partial productivity increased 37%; the production of soil testing and formula fertilization was 785kg/hm2more than conventional fertilization , increased 9. 9 %. |
