长江中下游农区黑麦草季节性栽培研究回顾与展望

Review and Outlooks on Seasonal Cultivation of Perennial Ryegrass in the Middle and Lower Farming Areas of the Yangtze River

黑麦草属牧草是一年生或越年生草本植物,约有10个栽培种,主要分布在世界温性湿润地区,在我国也有广泛种植,尤其以长江流域及以南地区有较大的栽培面积及配套的利用模式。本研究结合前人在长江中下游农区开展的黑麦草栽培的相关试验结果与本课题组的有关试验研究,探讨了当前及今后长江中下游农区充分利用冬闲田与非耕地资源的现实条件下,如何设置科学可行的种植制度、播种方式、肥料运筹、刈割时间和高度、田间管理等措施进行黑麦草季节性栽培。研究指出了当前黑麦草季节性栽培生产需要注意的问题与今后开展该项工作的努力方向,为该地区优质饲草科学生产提供了借鉴与参考。

Pastures of the genus lolium are annual raw herbs or perennial herbaceous plants which have around 10 cultivated species. They are mainly distributed in the warm humid regions of the world,and they have been widely cultivated in China, especially in the south of the Yangtze river basin and region where there are Large planting areas and the related complete set mode.This study is meant to discuss how to set the scientific and feasible cropping system and planting mode,fertilizer management,mowing time and height,field management to improve the seasonal cultivation of ryegrass to make the best of winter vacant fields and non-cropland re- sources in the middle and lower farming areas of the Yangtze river.We combine previous results on perennial ryegrass cultivation and some related experimental research carried by our studying team.This study points out some affairs needing attention and the direction of working efforts on perennial ryegrass cultivation in the future,intended to provide some reference to produce higher quality forage grasses.
