摘要
采用二次饱和D—最优设计 ,研究了有机肥与化肥配施对水稻土B层速效磷积累量的影响 ,并建立了数学模型 ,同时解析了各因素对水稻土B层速效磷积累量的影响 。
The paper studied the effect of mixed application of organic and inorganic fertilizers on content of available phosphorus in B horizon of paddy soil with saturated D_optimal design for quadratic regression,established mathematical model,analyzed effects of all kinds of factors on content of available phosphorus in B horizon of paddy soil,and offered a fertilizer applying plan to reduce content of available phosphorus in B horizon of paddy soil.
