水稻强化栽培中不同种类肥料对土壤理化性状的影响

Effect of different kinds of fertilizer on the yield and physical and chemical status of soil in SRI

本试验通过水稻强化栽培技术中使用不同种类的肥料比较,探讨了在氮磷钾肥施用量相同的情况下,不同肥料种类对水稻产量及土壤理化性状的影响。结果表明:在水稻强化栽培中,采用化肥与有机肥配合施用,既可以满足水稻生长发育需要,提高籽粒产量,又有利于改善土壤理化性状,提高肥料的当季利用率。

By way of supplying the equal amount of N,P_2O_5 and K_2O but different kinds of fertilizer in the system of rice intensification(SRI),the changes of grain yield and physical and chemical status of soil were analyzed.The results showed:the coordinate supply of chemical and organic fertilizer in SRI not only promoted the development of plant and increased grain yield,but also improved physical and chemical status of soil and increased the utilization rate of fertilizer.
