摘要
研究不同株距对苜蓿种子产量及相关因素的影响。通过3年的试验结果表明，在5—70cm的8个处理间，株距40cm和50cm处理种子产量为最高，平均产种子219．0kg／hm^2和211．7kg／hm^2，显著高于其他6个处理，前者好于后者。苜蓿单株分枝数、小花数、结荚数和千粒重随着株距加大而有增加趋势。但以株距40cm处理综合比较表现为优。
The object of this experiment is to determine the effect on alfalfa seed yield and another factors at different level of plant distance. The 3-year results showed that the seed yield at the plant distance of 40 cm and 50 cm were the most in the whole plant distance （from 5 cm to 70 cm）, and-average yield were 219.0 kg/ha and 211.7 kg/ha, and the significant higher than the other distance treatment. The shoots,racemes, pod and TSW increased with distance increasing, and the performance of 40 cm appeared best in all treatments by synthetical contrast.
