【摘要】 研究了新引进黑麦草品种冬牧70黑麦草、多年生黑麦草、特早熟二倍体黑麦草、意大利四倍体黑麦草与本地多花黑麦草的物候期、生育期、鲜草量、营养成分等。结果表明:冬牧70黑麦草产量和粗蛋白含量比多花黑麦草高;特早熟二倍体和意大利四倍体黑麦草生育期长,可延长金衢盆地黑麦草利用期1个月左右。多年生黑麦草除了营养价值较高外,在物候期、生育期方面无明显优势。更多还原

【Abstract】 <Abstrcat>This experiment compared phonological period, growth rate, fresh grass yield, and nutrition component of newly introduced ryegrass varieties (Dongmu-70,Lolium perenne L.,Precocious dualploid ryegrass, Italy tetraploid ryegrass) with local Lolium sp.in Jinqu basin. The results showed that Dongmu-70 had higher yield of fresh grass and protein content than did Lolium sp.precocious dualploid ryegrass and Italy tetraploid ryegrass had longer growth periods and elongated utilization period for approximately one month. Apart from the higher nutrition component,Lolium perenne L. had no obvious advantages in the phonological period and growth rate.更多还原
