本文研究了五种豆科冬季绿肥与非豆科黑麦草混播的效果.在新垦第四纪红色粘土岗地上混播比豆科单播每亩增产鲜草230～937.1kg,增加23.6～114.2%,于重增加43.3%～97.8%,植株养分氮增加23.6%～41.6%;磷8.0%～59.4%;钾56.2～187.2%,显著改善了绿肥品质. In this paper, the effects of five legumes winter green manure and non-leguminous ryegrass mixed sowing were studied.The yield of fresh grass was increased by 230 ~ 937.1 kg per acre than that of leguminous monoculture in the newly reclaimed Quaternary red clay hillock, increasing by 23.6 ~ 114.2% , Increased by 43.3% ~ 97.8%, nitrogen increased by 23.6% ~ 41.6%, phosphorus increased by 8.0% ~ 59.4%, potassium increased by 56.2 ~ 187.2%, which significantly improved the quality of green manure.
