摘要

接种豆类通常被认为可以提高产量,降低对氮的需求,尤其是在半干旱地区和沙质土壤上。目前尚不清楚在瑞典条件下种植蚕豆(小蚕豆)时接种根瘤菌是否能提高产量和蛋白质含量。2015-2016年,在瑞典中部的田间试验中,对三个蚕豆品种和两个根瘤菌菌株进行了研究,包括使用15N丰度分析固氮能力。该研究没有显示接种根瘤菌对蚕豆产量或蛋白质含量或随后的春小麦产量有任何影响。蚕豆的产量因品种而异,但与接种无关。根瘤菌对15N丰度有影响。这项研究不能支持这样一种观点,即在斯堪的纳维亚田间条件下,接种蚕豆有利于改善蚕豆种植效果。接种后对春小麦产量无残留影响。

Effect of cultivar and inoculant on yields of faba beans (Vicia faba minor) and subsequent spring wheat (Triticum aestivum) under Scandinavian cropping conditions
Inoculation of legumes is generally considered to increase yield and to lower the need of nitrogen (N) fertilization, especially in semiarid regions and on sandy soils. It has not been clear whether inoculation with Rhizobium sp. in cropping of faba beans (Vicia faba minor) under Swedish conditions would improve yield and protein content. In 2015–2016, three faba bean cultivars and two strains of Rhizobium were studied in field trials in Central Sweden, including analyses of N fixation capacities using 15N abundance. The study did not show any effects of inoculation of Rhizobium on yield or protein content of faba beans or subsequent spring wheat yields. Yields of faba beans varied between cultivars but were not connected to inoculation. 15N abundance was influenced by rhizobium. The study cannot support the opinion that, generally, inoculation is beneficial for improved outcome of faba bean cropping under Scandinavian field conditions. No residual effect of inoculation on subsequent spring wheat yield was found.
