黑麦草与豆科绿肥苕子、金花菜、紫云英、箭舌豌豆等混播,近年来已在生产中示范和推广。实践证明,这是合理利用土壤养分,提高绿肥产量,改良土壤和改善土壤供肥状况的有效措施。本文就黑麦草与豆科绿肥混播的增产效果、改土作用,应用技术等,提出一些试验研究结果。 Ryegrass and Leguminosae fertile prickly heat, Cauliflower, Astragalus, arrow tongue peas and other mixed broadcast, in recent years has been demonstrated in the production and promotion. Practice has proved that this is an effective measure to make rational use of soil nutrients, increase green manure yield, improve soil and improve soil fertility. In this paper, the effects of increasing yield of mixed ryegrass and leguminous green manure, soil modification and application technology are put forward. Some experimental results are presented.
