Abstract: A study of the effect of row spacing and sowing rate to white clover shows that the higher the sowing rate and wider the row space,the longer the plant growing period,and taller the height of canopy and reproductive branches,and more abundant the seed yield.Different treatments of cultivated white clover varied the percentages of dry matter distribution in the root,the stem,and the leaf calculated in the harvesting stage.The percentage of dry matter distribution in the flower and the seed under Treatment 2 reached 34.93% and 12.98% respectively,the highest of all.Treatment 3 topped the others in seed yield,its potential seed yield amounted to 1046.2 kg/hm2 and its harvested seed yield,443.1 kg/hm2.

摘要： 研究行距和播种量对白三叶(Trifolium repens L.)生长发育及种子产量的影响。结果表明:行距和播量影响白三叶的生育进程,随着播量和行距的增大,生育时期延长,冠层高度、生殖枝高度和种子产量增加;各处理干物质分配规律不同,在收获时,处理2的花和种子比例最大,分别达34.93%和12.98%;处理3种子产量最高,其潜在和实际种子产量分别达1046.2和443.1kg/hm2。
