摘要
通过不同株行距处理对苜蓿生长发育、群体结构、结实特征以及种子产量影响的研究,发现株距对苜蓿生长速度、茎粗、分枝数、花序数、结荚数、花荚脱落率和种子产量等的影响大于行距的影响。制种苜蓿最佳密度配置方式为行距60cm,株距30cm,这一株行距下苜蓿单株分枝数多,枝条粗壮,株丛较矮,不易倒伏,产量达1182kg/hm2。
On the basis of study on growth,population structure,bearing characters and seed yield of alfalfa were analyzed with the treatment of different plant row space.It was found that the effect of plant space on growth speed,stem diameter,branch number,inflorescence number,pods number and seed yield is more significant than that of rows space.The highest seed yield of alfalfa reached 1 182 kg per hm^2 which has been obtained from the plots with 60 cm of row space and 30 cm of plant space.
