小麦种内混作研究进展

Research Progress of Mixed Cropping within Wheat Varieties

混作是千百年来我国农业遗产的重要组成部分,是精耕细作、集约种植的一种传统技术。小麦又是我国三大粮食作物之一。综述了不同小麦品种混合种植产量增加的机理,概述了现有的小麦混作的模式及其不同品种的配比原则,以及小麦混作在环境保护中的积极作用,指出了未来小麦种内混作的研究方向,提出了在小麦种内混作实践过程中应该注意的问题,以期为进一步的提高混作小麦复合群体的生产潜力提供参考。

Intercropping is the most important part of the agricultural heritage and a traditional technology of intensive cultiva- tions for the past thousands years in China. Wheat is one of the important food crops in China. The mechanism of mixed crop- ping within wheat varieties was reviewed in the paper. The models and matching principles of mixed cropping within wheat va- rieties were summarized. At the same time, the positive effects of mixed cropping wheat varieties were shown in environmental protection. Moreover, the research direction of mixed mode of different wheat varieties would be pointed out in the future. It provides some issues we should pay attention to in the process of practice, and references for the further study on improving the production potential of intercropping wheat composite group.
