给热带豆科作物施肥收效不大,可能主要是因为土壤缺乏微量元素和因没有合适的根瘤菌菌株而结瘤不良所致。结瘤不良可通过接种合适的根瘤菌和施用微量元素得到改善。本试验目的在于探讨接种和不接种根瘤菌的情况下,施用 Cu、Zn 对夏播绿豆生长、结瘤和产量的影响。1981和1982年夏季,以 Pusa Baisakhi 品种为材料在印度北方邦 Varanasi 地区一农田 Fertilization of tropical leguminous crops with little benefit may be mainly due to the lack of trace elements in the soil and the lack of proper rhizobia strains that cause poor nodulation. Poor nodulation can be ameliorated by the inoculation of the appropriate rhizobia and the application of trace elements. The purpose of this experiment is to explore the effects of Cu and Zn on the growth, nodulation and yield of mongolian mung bean under inoculation and non-inoculation with Rhizobium. In the 1981 and 1982 summer, the Pusa Baisakhi variety was used as a material in a farmland in Varanasi, Uttar Pradesh, India
