通过田间试验,研究了单作马铃薯、马铃薯/蚕豆间作和单作蚕豆对干物质积累以及氮、磷积累量的影响。结果表明,在马铃薯和蚕豆共生期内,马铃薯植株和各器官干物质累积受到明显的抑制作用,蚕豆收获后,马铃薯各器官干物质累积促进,间作处理马铃薯植株干物质累积为304.03g/株,大于单作处理的298.29g/株。在苗期,间作处理较单作处理对马铃薯根和叶的全氮累积分别提高了36.52%和17.41%,间作对茎全氮累积具有抑制作用,在生长后期间作处理较单作对马铃薯根、茎和叶全氮累积分别提高了68.68%、42.98%和109.48%,促进作用很明显。在苗期间作处理较单作处理对马铃薯各器官全磷累积具有促进作用而在块茎形成期只对根和叶全磷累积有促进作用,但随着生育期推进反而对不同器官全磷累积都起到抑制作用。
Field experiments were conducted to study the effects of single cropping potato / potato / broad bean intercropping and monoculture broad bean on dry matter accumulation and nitrogen and phosphorus accumulation. The results showed that during the symbiotic period of potato and faba bean, the accumulation of dry matter in potato plants and organs was significantly inhibited. After harvest, the accumulation of dry matter in various organs of potato was promoted. The dry matter accumulation of potato plants was 304.03g / plant, 298.29g / plant larger than the single treatment. At the seedling stage, intercropping treatment increased the total nitrogen accumulation in roots and leaves of potatoes by 36.52% and 17.41% compared with single treatment, respectively. Intercropping had inhibitory effect on the accumulation of total nitrogen in stems, The accumulation of total nitrogen in stems and leaves increased by 68.68%, 42.98% and 109.48% respectively, and the promotion effect was obvious. Compared with the control, the accumulation of total phosphorus in all organs of potatoes was promoted during the seedling stage, but only during the tuberization stage, which could only promote the accumulation of total phosphorus in roots and leaves. However, Inhibition.
