摘要
对从美国引进的4种紫花苜蓿MHA1,MHA2,78,78-1和中国的中苜1号进行栽培比较试验.从种子发芽率、茎叶比、鲜干比、鲜草产量、营养成分和经济效益等方面进行了对比分析.结果表明,上述各性状以78-1表现最为突出,粗蛋白、粗脂肪、Ca,P含量高,品质优良,经济效益显著,有较大推广价值.其余3种美国苜蓿品种在河南有推广意义.
Cultivation experiments were conducted to compare 4 introduced alfalfa varieties from USA MHA1,MHA2,78,78-1 and the domestic variety of Zhongmu No.1 for the germination ratio, stem/leaf ratio, green grass/hay ratio, green grass yield, nutritive composition and economic profit. The results showed, the variety 78-1 performed the best on the CP, EE, Ca and P content, 78-1 produced high quality grass with remarkable economic benefit which was worth extending on large scale. The other three introduced alfalfa varieties are also worth extending in Henan Province.
