摘要
研究在水田冬种黑麦草（Ｌｏｌｉｕｍｍｕｌｔｉｆｌｏｒｕｍ）对后作水稻的作用机理，通过水培试验，探讨了接种和不接种南亚热带稻田土壤微生物条件下黑麦草品种樱早生和早生丰的生长发育和氮素营养．结果表明，稻田土壤微生物参与并促进了黑麦草的物质生产过程。
In order to clarify the affecting mechanism of ltalian ryegrass (Lolium multiflorum) winter cropping in paddy on subsequent rice, growths and nitrogen balances of plants of ltalian ryegrass cultured in mediums infected and disinfected with soil microorganisms, which was collected from paddy in southern subtropics of China, were investigated. It was shown that infection of infection of the soil microorgnisms increased dry matter production of Italian ryegrass. The result proved that the increment of strain yield of rice in the paddy precultivated Italian ryegrass in winfer has a direct bearing on the rhizosphere activity of the ltalian ryegrass.
