摘要
阐述了国内外苜蓿间作的研究进展情况,总结了苜蓿草田间作在光合效应、土壤结构及肥力的改善与恢复及抗逆性等方面的生理生态效应。苜蓿间作可以充分利用光、水、热、肥等条件,从而达到提高产量和品质的目的。间作可以改变小气候,使群落环境得到改善,且对病虫害等有一定的抑制作用,还可提高土壤光能利用率,增加经济收入。
The research progress on alfalfa intercropping was reviewed.The physiological and ecological effects such as photosynthetic effects,improvement and restore of soil fertility and resistance were summarized.Alfalfa intercropping system can effectively utilize the light,water,energy and nutrients and then improve the yield and quality.Alfalfa intercropping can change the microclimate,improve the community environment and inhibit diseases and pests.It also can improve the land utilization efficiency and increase the economic income.
