摘　　要：对六种饲料作物在民和县河谷川水地区进行了复种栽培试验,结果表明：覆膜对饲料作物的植株高度、产量都有显著的作用。覆膜比不覆膜平均鲜草产量高28 206.0-56 202.0kg/hm2,增产51.4%-127.6%,经济效益明显,甘露2号高丹草和科青1号饲用玉米综合性状表现最优,是适宜该地区二茬复种的优良饲料品种。Replanting experiment of 6 species of feed crop was conducted in the area of irrigated land along rivers in klinhe county. The results indicated that ground film affected plant height and yield of feed crop when crop was covered film, average fresh grass yield was increased 28 206.0 - 56 202.0kg/hm^2 than that of withont covering ground film. Increased production was 51.4% - 127.6%. The economic profit was remarkble. The comprehensive performance of No. 2 Ganlu Sorghum and No. I Keqing feed corn were best among 6 species.
