摘要
实验研究了不同播种时期(5月1日、5月11日、5月21日)对瓜尔豆生长发育和产量的影响.结果表明:5月1日至5月10日之间播种,对瓜尔豆的产量和质量没有显著影响;但5月21日播种,瓜尔豆的单株粒重、千粒重降低,单株结荚数和小区产量显著减少.实验所用的瓜尔豆从播种至齐苗、从齐苗至开花、从播种至种子成熟所需的有效积温(地下5处的温度≥15℃)分别为188.59±10.29℃、479.08±7.03℃、3111.34～3235.84℃.
In this article, effects of three kinds of sowing date on growth and yield of Clusterbean （Cyamopsis tetragonoloba ） were studied. The result showed that the difference of seed yields and quality were not distinct when sowing dates were between 1 May and 11 May. Seed yield/plant and 1000-seed-weight were loweron the sowing date of 21 May than 1 or 11 May. Pots/plant and seed yield decreased significantly when sown on 21 May. The effective accumulated temperature（the ground temperature of 5cm≥ 15℃ ） from sowing to seedling emergence or from seedling emergence to anthesis or from sowing to seed harvest is 188.59 ± 10.29℃ ,479.08 ± 7.03℃ ,3111.34℃ ± 3235.84℃, respectively.
