不同基础肥力水稻土对施肥响应的差异性研究进展

Research Progress on Difference of Response to Fertilization in Paddy Soils with Different Basic Fertility

土壤基础肥力是保证水稻高产的关键因素。不同肥力水平土壤的理化性质、生物学特性对水稻的生长发育、产量及产量形成的影响有所差异。合理施肥、土壤培肥是解决土壤肥力低下的有效措施。文章综述、归纳和分析了不同肥力土壤的差异性,针对不同基础地力的土壤提出了一些培肥措施,以期为水稻因地制宜制定高效施肥技术提供参考。

Soil basic fertility is a key factor to ensure high yield of rice. The physicochemical properties and biological characteristics of soil in different fertility level have different effects on the growth, yield and yield formation of rice. Reasonable fertilization and improvement of soil fertility are effective measures to solve the problem of soil fertility. This article summarized and analyzed the difference of different fertility soil, proposed some measures to improve soil fertility according to different basic soil fertility, so as to provide some reference for the development of high-efficiency fertilization techniques for rice in accordance with local conditions.
