植物群落中植物间相互关系问题是地植物学的基本问题之一。苏联地植物学工作者在 B·H·苏卡切夫的倡导下,六十年代前后把对这一问题的研究从一般调查、描述阶段提高到了实验阶段,基于过去把森林中植物间相互关系的原因往往只归结于林冠下的植物气候,尤其是光照条件,所以他们集中地开展了森林中植物根系间对水分和营养物质的竟争在它们相互关系中作用的实验研究,并获得了一批研究成果,发表了一批有关这一问题的专门论文。这一工作首推 B·Γ·卡尔波夫,他的试验是在苏联欧洲部分泰加森林中进行的,最初他研究了云杉林和桦树林的树木根系与在林下播种及栽植的云杉和桦树幼苗的相互关系,试验分5个处理:①对照;②去除灌木——草本和藓被层;③ Plant communities in the relationship between plants is one of the basic problems of botany. The botanical workers in the Soviet Union promoted the research on this issue from the general investigation and description stage to the experimental stage around the 1960s, under the advocacy of B.H.Sukachev. Based on the past analysis of the relationship between plants in the forest Are often attributed only to the plant climate under the canopy, especially to the light conditions, so they conducted an experimental study focused on the role of competition among plants in the forest on water and nutrients in their interactions and obtained a Batch of research results, published a number of special papers on this issue. His work was devalued by B. Γ Karpov. His experiments were conducted in the Thai part of the Soviet Union, the Taygar forest. He initially studied the tree roots of spruce and birch forests and the cloud planted and planted under the trees Cunninghamia lanceolata and birch seedlings, the experiment divided into five treatments: ① control; ② removal of shrubs - herbs and moss layer; ③
