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。
Under the soil conditions of clay soil and sandy loam soil, the effects of five nitrogen fertilizers and three planting densities on the nodulation and growth of broad bean were studied. The results showed that the nodulation ability of Vicia faba varied greatly under different soil conditions. Appropriate nitrogen application rate could improve the nodulation ability of Vicia faba under the nitrogen application rate of less than 240 kg / hm2. The line spacing of broad beans increased from 25cm to 50cm, reducing the nodulation ability of broad beans planted on clay soil, but increased the nodulation ability of broad beans planted on sandy loam soil. Similarly, the proper amount of nitrogen fertilizer application, broad bean biomass, effective pods, grain yield and plant height were improved. Increasing the row spacing of broad beans, promoting broad bean biomass, effective pods, grain yield, reducing the plant height of broad beans.
