摘要
小麦和白三叶草（Ｔｒｉｆｏｌｉｕｍｒｅｐｅｎｓ）复合共生，是一种新型的农田人工群落。其功能表现为种养（养地与养殖）的有效结合，并通过小麦与三叶草的群体优势抑制农田杂草种群。因此，在理论上，这种复合群体是多功能效益，而且是相对稳定的农田生态系。在生产实...
The interaction of wheat with Trifolium repens in the complex community was studied and the results showed that 1) stratification of the above-ground parts occurred and wheat roots were better developed in the complex community; 2) intercropped Trifolium repens with wheat could improve yield components of wheat in edge lines and lead to 17.9% more yield compared with that of wheat in the midle line,resulting in higher yield per unit of net planting area of wheat in intercropping community than that in sole cropping; 3) inhibition to growth of Trifolium repens was significantly related to leaf area of wheat in the edge liness; 4) the yield of intercropped wheat was higher than that in sole cropping when sowing area of wheat in intercropping was more that 85% of the total area, whearas when this ratio was less than 75%, the yield of intercropped wheat was lower than that of sole cropping; and 5) wheat yield in mix-cropping was higher than that in sole cropping. It is concluded that wheat is predominant population in wheat and Trifolium repens complex community.
