摘要
就扁蓿豆在呼和浩特地区栽培条件下的开花时间和花蕾、花、荚的脱落进行了研究.结果表明,在呼和浩特地区扁蓿豆每日内花朵集中开放的时间为10：00～14：00,开花时的最适宜温度为29～32℃,适宜湿度为54%～64%.扁蓿豆的花蕾、花及荚的脱落中,以落花为主,其次是落荚,花蕾的脱落最少.扁蓿豆结荚率为32%～43%,落花和落荚是限制其种子高产的重要因素.
The time of flowering and the shedding of bud, flowering and pod of Melilotoides ruthenica in Ho- hhot were researched. The results showed that, the time of flowering was from 10：00 to 14：00 in Hohhot, the best fitting temperature of flowering is 29 -32℃, humidity is 54% -64%. The shedding of flowering and pod were higher distinct than that of bud. Siliqua percentage of Melilotoides ruthenica is 32% -43%, seed yield is restricted by the shedding of flowering and pod.
