摘要
试验证明,每公顷燕麦150—187.5kg、箭舌豌豆75—60kg的混播量均适于我省农区低、中、高位不同山地,其中以燕麦150kg、箭舌豌豆75kg的混播比例为最佳混播组合量,其鲜草产量比单播燕麦及箭舌豌豆分别增加28.3%和20.5%。在混播草层中,燕麦对箭舌豌豆起支撑作用,使箭舌豌豆在不同山地比单播株高平均增长15.6cm,在高位山地株高平均增长24.7cm。
The experiment was conducted at three sites (nonirrigated farmlands of low, middle and high mountain area)in 1991. The result showed that the seeding rates of 150—187. 5kg/ha of oats(Avena sativa L.)and 60—75kg/ha of common vetch(Vicia sativa L.)were suited for all three locations. Of them, 150kg/ha of oats and 75kg/ha of common vetch was the optimal one,which gave 28. 3%and 20. 5 %more fresh herbage yields than pure oats and common vetch stands respectively. The height of common vetch tended to be greater with mixtures than with itself alone because of the support from oats.
