摘要
报道了１９９５～１９９７年对冬牧７０黑麦连续两季利用冬闲田进行不同播种量大田种植试验研究的结果．试验结果表明：冬牧７０黑麦最佳播种量是（５～７．５）ｋｇ／６６６．７ｍ２．首次刈割鲜重产量达２０００ｋｇ／６６６．７ｍ２左右，干重产量达８００ｋｇ／６６６．
This paper presents the experiments on winter herd 70 rye,
a variety of Lolium peremme L. introduced from USA, by changing the sowing norm in
successive two cultural seasons during 1995-1997 in Tianjin. Results showed that the best
sowing norm was between 5 kg --- 7.5 kg/666.7 m 2, which yielded a fresh weight of about 2 000
kg/666.7 m 2 and a dry weight about 800 kg/666.7 m 2 at first crop.
