摘要
为了探究刈割对紫花苜蓿种子产量的影响,试验分别设置5月23日、5月31日、6月7日、6月14日刈割处理紫花苜蓿种子生产田,成熟期测定种子产量及构成因子各项指标。结果表明:6月7日刈割处理的种子产量显著高于对照组(P<0.05),其他刈割处理种子产量与对照组差异不显著(P>0.05)。
In order to explore the effect of mowing on seed yield of Alfalfa,the experiment was set up on May 23,May 31,June 7,and June 14.Various indicators of the seed yield and constituent factors were determined at the maturity period.The results showed that cutting treatment of the seed yield on June 7was higher than of the control significantly(P<0.05),and other mowing treatments were no different from the control significantly(P>0.05).
