摘    要:通过测土配方施肥与常规经验施肥比较的方法,研究测土配方施肥的增产效果,结果表明:测土配方施肥较空白增产178.7kg/667m2,增产比率达50%,增效231.15元/667m2,较常规施肥增产30.2kg/667m2,增产比率达6.3%,增效39.90元/667m2;通过测定分析,水稻对土壤养分的依存率为70.7%;秋收实际水稻单产与目标产量进行比较,偏低13.8kg,目标产量吻合度为97.5%.

Abstract:Compared with the regular fertilization,the increasing effect of formula fertilization by soil testing was investigated.The results showed that in comparison with control and regular plots,rice yield in plots where formula fertilization by soil testing was applied,increased 178 kg/667m2 and 30.2 kg/667m2,corresponding to 50%,6.3% of increasing rate, and the net income was enhanced 231.15 yuan/667m2,39.90 yuan/667m2,respectively.Through determinating analysis,we found that the dependent rate of rice on nutrient was 70.7%.The rice yield obtained at harvest was lower 13.8 kg than that of expected yield,the identical degree reached 97.5%.
Keywords:rice  formula fertilization by soil testing  effect
