摘要
通过对不同苜蓿品种头茬草产量及经济价值的研究结果表明:参试品种干草产量之间差异极显著(P<0.01),其中牧歌401最高(9516.48kg/hm2),中兰一号次之(9282.47kg/hm2),哥伦布最低;经济价值最高的为卫士30210.88,最低的为戴尔9.72。
Changes of hay yield and economic values were Studied.Preliminary results indicated that there were significant difference among hay yields of 31 different alfalfa, of all, Amerigraze 401+Z was the highest, its hay yield was 9516.48 kg/hm^2; Coumbo was the lower. Comprehensive appraisal on economic value of 31 alfalfa showed that Ameriguard 302+Z was the first.
