中文摘要：
在胶泥土和沙壤土两种土壤条件下,研究了5种氮肥用量和3种种植密度对蚕豆结瘤和生长的影响。结果表明：蚕豆在不同土壤条件下结瘤能力差异较大,在氮肥施用量低于240kg/hm2的情况下,适当提高氮肥施用量有助于提高蚕豆的结瘤能力。蚕豆的行距从25cm增加到50cm,降低了种植在胶泥土上蚕豆的结瘤能力,却提高了种植在沙壤土上蚕豆的结瘤能力。同样,适量提高氮肥的施用量,蚕豆的生物量、有效荚数、子粒产量和株高均得到提高。增加蚕豆的行距,促进蚕豆的生物量、有效荚数、子粒产量,降低了蚕豆的株高。
英文摘要：
The present study was conducted to investigate the role of nitrogen application and planting density on faba bean nodulation and plant growth at five amount of nitrogen application and 3 planting density.The level of faba bean nodulation was improved when nitrogen fertilizer application was properly increased（below 240kg/hm 2） in both two soil conditions.Nodulation level of faba bean in clay soil was increased while it was increased in sandy loam soil when row space was expended from 25cm to 50cm.Faba bean biomass,effective pod number,economy yield and plant height were increased when application amount of nitrogen was increased in acceptable area.Biomass,effective pod number,and economy yield were increased and plant height was decreased when plant row space was expended.
