摘要
化肥作为重要的农业生产资料,对粮食增产的贡献率在40%以上,但长期使用所带来的资源浪费和面源污染等问题同样亟待23解决。控释肥料能控制养分在土壤中的释放,让养分供应与作物各生育期对养分的吸收相同步,对化肥减施增效、提高作物产量和促进农业可持续发展具有重大的战略意义。稻麦轮作是我国一种重要的粮食作物种植制度,控释肥在稻麦轮作体系上的应用能够在保障粮食增产稳产的基础上,提高氮肥利用率、减少面源污染。本文从控释氮肥的研究进展、控释氮肥对稻麦轮作系统的影响因素以及影响控释氮肥肥效的因素等方面,为小麦、水稻专用控释肥的开发,以及控释氮肥在稻麦轮作系统中的生产应用及推广提供理论依据。
As an essential input for agricultural production,chemical fertilizers contribute to over 40%of grain productionincrease,but the problems of resource waste and non-point source pollution caused by the long-term use of chemical fertilizer also need to be solved urgently.Controlled release fertilizer can control the release of nutrients in the soil,so that thenutrient supply is synchronized with the absorption of nutrients in each growth period of crops.It is of great strategicsignificance in chemical fertilizer reduction and synergism,and can improve the crop yield and promote the sustainabledevelopment of agriculture.Rice-wheat rotation is an important food crop planting system in China.The applicationof controlled release fertilizer in rice-wheat rotation system can improve nitrogen fertilizer efficiency and reduce non-point source pollution on the basis of ensuring grain yield stable and increased.We summarized and analyzed the research progress of controlled release urea,the factors of controlled release nitrogen fertilizer on rice-wheat rotation system and the factors of affecting controlled release fertilizer efficiency.It can provide theoretical basis for the development of wheat and ricecontrolled release fertilizer,and provide reference for the production,application and promotion of controlled releasefertilizer on rice-wheat rotation system.
