合理密植是大豆增产的中心措施。在大豆栽培上,植株密度不同,使大豆群体结构表现出很大的差别。加大植株密度的结果,直接地使群体和个体之间的矛盾激烈化,因此,必须采取相应的农业措施来解决这个矛盾,才能很好地发挥合理密植的增产作用。为此,应该深入研究大豆群体发展的规律,阐明大豆植株密度与品种特性、土壤肥力条件以及其他栽培措施的关系,从而具体地找出贯彻合理密植的途径。
Reasonable close planting is the central measure of soybean production. In soybean cultivation, plant density, so that the structure of soybean populations showed great differences. Increasing the plant density results in the intensification of contradictions between groups and individuals directly. Therefore, corresponding agricultural measures must be taken to resolve this contradiction so as to bring the production of rational and intensive planting into good play. Therefore, the law of soybean population development should be studied in depth, and the relationship between plant density and variety characteristics, soil fertility conditions and other cultivation measures should be elucidated.
