国内外粮草耦合研究现状概述

The Current States and Progress of Forage and Crop Rotation at Home and Abroad

粮草耦合对我国农业结构调整及农业可持续发展具有重要意义。将饲草与粮食作物有机结合,既提高了粮食产量,又为家畜提供了充足的饲料,还可促进土壤养分循环以及保持水土、防治杂草等。因此,本文概述了近年来国内外粮草耦合相关研究进展,着重综述了粮草耦合对土壤理化性质、作物产量品质的影响以及所带来的生态效益,同时也初步探讨了三峡库区粮草耦合模式,旨在为西南地区粮草兼顾型农业的发展提供技术支撑及理论依据。

The vigorous implementation of forage and crop rotation is of great significance to the current agricultural structure adjustment and agricultural sustainable development in China. The combination of forage and crops not only improves food production,but also provides sufficient feed for livestock,and promotes soil nutrient cycling,soil and water conservation,and weed control. Therefore,this paper summarized the impact of grain and grass coupling on soil physical and chemical properties,the impact on crop yield and quality,and the ecological benefits brought by it. It also preliminarily discussed the coupling of forage and crop rotation in the Three Gorges reservoir area.The aim is to provide technical support and theoretical basis for the development of grain and grass-type agriculture in the Southwest.
