摘  要:
于深秋至晚春 ,在桂牧 1号草地的行间种植一年生黑麦草 ,观察测定这种种植方式给 2种草及草地带来的影响。试验设计 3个处理 :①在桂牧 1号草地内冬种一年生黑麦草 ,②单种桂牧 1号 ,③单种一年生黑麦草。把处理②的产草量与处理③的首次产量相加作为处理④ ,以代表桂牧 1号与一年生黑麦草轮作时的产量。结果是 :处理①与②中桂牧 1号的越冬率无显著差异 ;处理①的单位面积产草量极显著高于②、④ ;春季 ,处理①的杂草极显著地少于②。这表明 ,在桂牧 1号草地内冬种一年生黑麦草是可行可取的。

摘  要:
From late autumn till next late spring, annual ryegrass was seeded among the rows of Pennisetum purpureum cv. 'Guimu 1' grassland. Then the effects on the two grasses and the grassland were observed and determined. Three treatments were designed: ① Annual ryegrass was planted in the grassland where 'Guimu 1' had been planted;② 'Guimu 1' was planted only;③ Annual ryegrass was planted only. The sum of the output of ② and the first output of ③ was regarded as the output of the crop rotation of 'Guimu 1' and annual ryegrass. It was marked ④. The results showed that the rates of 'Guimu 1' living through the winter between ① and ② had no significant difference;The yield of perunit area of ① was extremely markedly higher than that of ② or ④;In spring, the weed of ① was extremely markedly less then that of ②. It indicated that it was feasible and advisable to plant annual ryegrass in winter in 'Guimu 1' grassland.
