摘 要：
在南京地区研究了不同前作(水稻Oryza satica和杂交狼尾草Pennisetum americanum×P.purpu-reum)对冬牧70黑麦Secale cerealevar.Dongmu 70产量、再生情况和营养品质的影响。结果表明:水稻茬种植的冬牧70黑麦较杂交狼尾草茬种植的再生茎蘖数多,株高高,干物质积累多;水稻茬冬牧70黑麦,2次刈割鲜干比也明显比杂交狼尾草茬的高,第2次刈割的茎叶比较杂交狼尾草茬的低。因此,在水稻茬种植冬牧70黑麦产量较高,品质也较好。

摘 要：
This experiment was conducted to study the effect of different preceding crops of rice and hybrid Pennisetum on yield,regeneration and forage quality of rye in Nanjing.The result showed that: rye with a preceding crop of rice has more regenerative tillers,higher plant height,and accumulate more dry matter than those with a preceding crop of hybrid Pennisetum.Ratio of fresh weight to dry weight(FW/DW) of two times of rye with a preceding crop of rice cropping after rice was higher than that of rye with a preceding crop of hybrid Pennisetum.And the ratio of stem to leaf of second time of rye with a preceding crop of rice was lower than that with a preceding crop of hybrid Pennisetum.In summary,the yield and quality of rye with a preceding crop of rice were better than those with a preceding crop of hybrid Pennisetum.
