摘要
对草、麦带状间作的牧草分层、分行及小麦分行产量、小麦分行穗粒重的研究表明:白三叶和紫云英生物量分布高度位于小麦种群高度之下,且对小麦边行或牧草自身边行的产量无影响。相反,箭舌豌豆和蚕豆因对边行小麦空间的侵占作用而影响间作群体的产量结构。文章分析了间作的生产效益,并讨论了改善群体结构的方法。
The layer,row and heading production of intercropping of legume forages with wheat were determinedand Compared with monocultural wheat. The results indicated that the distribution height of Trifolium repensand Astragalus sinicus were lower than that of wheat, which is no effecting to the edge production of wheat orforage. The production distribution was effected by Vicia sativa or Vicia faba through its space competition. But,the productive beneficts in all of the intercropping population was higher than that of monoculturalwheat.
