| 摘 要： | 自2002年起连续5年对关中地区7个高产紫花苜蓿品种的产量指标进行研究.结果表明,7个高产品种在关中地区生长良好,5年平均干草产量显著高于当地对照品种,其中"放牧者"最高,达27 243 kg/hm2,比CK高65.15%.各品种年际间产量差异显著(P＜0.05),最高产量出现在第3年,最佳利用年限为4年.累积株高与产量呈现极显著正相关(P＜0.01),可以用来估产.7个品种再生性比"关中"好,应加强后茬管理,以获得更高牧草产量.

| Abstract: | Yield characteristics of 7 high-yielding alfalfa varieties and native variety Guanzhong(CK) were evaluated from 2002 to 2006 in Guanzhong Region,Shaanxi province.The results showed that 7 varieties grew well in Guanzhong Region and had higher yield than native variety.Among them,Haygrazer had the highest average yield(27 243 kg/hm2) and was 65.15% higher than Guanzhong.The hay yields of each alfalfa variety in different years were significantly different(P<0.05).The highest yield occurred in the third year and the best utilization years were four years.Total height per year had significantly positive correlation with the hay yield(P<0.01),which can be used to estimate the yield.7 alfalfa varieties had better regeneration than Guanzhong. |
