| 摘 要： | 在甘肃酒泉地区研究刈割对紫花苜蓿种子产量和质量性状的影响,实验结果表明:未刈割处理的种子产量最高,为1040.5kg/hm2,孕蕾期刈割的种子产量最低,为854.3kg/hm2;随着刈割时间的推迟,荚果/结荚花序、种子数/荚果显著增加,而千粒重却明显降低;刈割显著降低了萌发种子的正常种苗数量,硬实率增加,但对正常种苗与硬实种子数之和却没有显著的影响。

| Abstract: | The effects of cutting on seed yields,seed yield components,and seed quality of alfalfa were studied in the experiment plots in Jiuquan,Gansu Province.The results show that the highest seed yield(1040.5 kg/hm~2)was obtained in the uncut plots(CK),while the seed yield after the cutting on May the 24th,during the bud stage,dropped significantly to 845.3 kg/hm~2.Delaying of the cutting time increased the rate of pods/raceme and of seeds/pod remarkably,but decreased the rate of florets/inflorescence and the thousand-seed weight(TSW).Cutting treatments influenced the seed quality significantly.Normal seedling percentage and hard seed percentage was reduced notably by cutting. |
