摘要
通过川西北高寒牧区黑麦与箭筈豌豆的混播试验,结果表明,箭筈豌豆在混播草群中所占的比例不超过50%时,混播产草量随箭筈豌豆在草群中所占比例的增加而提高,黑麦与箭筈豌豆混播比例为1∶1最优。
Through the mixed broadcasting experiment of Secale cereale Lrye and Vicia sativa Lrye in alpine pastoral area in northwestern Sichuan,the results showed that when the proportion of Vicia sativa Lrye was less than 50%,the total yield of grass increased by the increasing proportion of the Vicia sativa Lrye,and the optimal of mixed sowing proportion is 1 ∶ 1 for Secale cereale Lrye and Vicia sativa Lrye.
