摘要
对甘农3号紫花苜蓿进行了不同的行距处理,测定了不同处理的种子产量、有效分枝数/m2、花序数/m2、豆荚数/m2、种子数/荚、千粒质量等产量构成因素。对各行距处理下的种子产量进行了方差分析,结果表明:在行距100 cm处理下紫花苜蓿种子产量最高,40 cm处理种子产量最低;由通径分析结果得出,每平方米有效花序数和豆荚数对种子产量作用较大。
Medicago sativa cv. Gannong No. 3 was used to study the effect of row spacing on seed yield by measuring the seed yield, effective shoots/m^2, florets/m^2, seeds/pods and one thousand seed weight. The results shown that the highest seed yield was obtained under 100 cm row spacing, the seed yield was the lowest at 40 cm row spacing. The results of path analysis shown that florets/m^2 and pods/m^2 were the main factors to influence the seed yield.
