在优越的社会主义制度下,苏联的农业科学正日益进步。目前在苏联,关于植物土壤营养(即根部营养)问题和施肥问题的研究,又取得了新的辉煌的成就。这便是苏联全苏列宁农业科学院院长李森科院士所提倡的植物土壤营养的生物学观点,以及依据这种观点而创立的为有益的土壤微生物的生命活动创造有利条件的施肥理论。这种施肥理论,是根据苏联先进的米丘林农业生物学说和威廉斯土壤学说,从丰富的实践经验中总结出来的。这种生物学观点的施肥理论同过去的单纯化学观点的施肥理论,有着本质上的不同。
Under the superior socialist system, Soviet agricultural science is progressing day by day. Currently in the Soviet Union, new achievements have been made in the study of plant soil nutrition (ie, root nutrition) and fertilization. This is the biological view of plant soil nutrition advocated by the academician of the Soviet Union Su-ning Academy of Agricultural Sciences and the fertilization theory that is based on this view and that creates favorable conditions for the beneficial activities of soil microorganisms. This fertilization theory is based on the Soviet Union advanced Michurin agricultural biology and Williams soil theory, summed up from a wealth of practical experience. This biological concept of fertilization theory with the past purely chemical point of fertilization theory is essentially different.
