摘要: 为了确立宁夏平罗县水稻施肥指标体系,以指导当地水稻优质高效生产。试验设置无肥区和常规施肥区两个处理,采用多点无重复设置,把土壤基础肥力对水稻产量的影响进行深化分析研究。结果表明:土壤基础肥力对水稻产量的贡献率与水稻土壤基础产量成正比,回归方程式X/Y=0.1366+0.00007322X,R2=0.8509**。由此得出结论:水稻的目标产量可确立为11800 kg hm -2,此时,氮和磷的施肥指标值:纯N为371.2 kg hm-2,纯P2O5为154.0kg hm -2

Abstract: In order to establish the index system for fertilization in Pingluo County of Ningxia to guide the local rice, rice quality and efficient production. Two treatments without fertilizer area and the conventional fertilization, multi point no repeat settings, to deepen the study on the influence of soil fertility on yield of rice. The results showed that: Soil Fertility on Rice Yield and rice yield contribution rate of soil foundation is proportional to the regression equation, X/Y=0.1366 0.00007322X, R2=0.8509. So the conclusion is: the rice yield goal can be established for the 11800 kg hm -2, at the same time, nitrogen and phosphorus fertilizer index values: pure N 371.2 kg hm-2 , pure P2O5 for 154.0 kg hm -2.
