大约95%的植物种类都与自然界的某一类型的土壤真菌有共生关系.这些真菌增加植物对磷的吸收,并可以增加平均20%的产量.如众所周知的囊状灌木菌根真菌(VAM),这些有益的土壤微生物将它们自己与植物的根结合在一起,并且从土壤中吸取磷元素.这项研究课题是在1980年,由设在哥伦比亚的热带农业国际中心的西德人建立的.在研 About 95% of the plant species have symbiotic relationships with some types of soil fungi in nature that increase plant uptake of phosphorus and increase average yields by 20%, such as the well-known VAC fungus (VAM) , These beneficial soil microbes combine themselves with the roots of plants and extract phosphorus from the soil, a project that was established in 1980 by West Germans at the International Center for Tropical Agriculture in Colombia.
