【摘要】The yield - increasing effect of a high - yielding soybean production system is the result of the integration of various practices. Yield increasing effect of a given practice differs greatly due to production region and planting pattern. The current research examined the effect of different varieties, biological agents, herbicide antidotes, foliar agents and seed coating agents on soybean yield in northern Heilongjiang Province. It showed that variety and seed - coating agents had greater potential in increasing soybean yield. Newly released variety 1342 and variety 4404 had 10% and 6% yield gain due to greater pod number and higher 100 - seed weight compared to local dominant variety. Seed - coat agent increased yield by 9. 1%. The BRF -1 and root - protecting bioagent only showed a 6% and 5% yield gain respectively although they could enhance dry matter accumulation. The application of foliar agent at early flowering increased yield in soybean by 6. 7%. The herbicide antidotes had no effect on soybean yield The yield - increasing effect together with environmental safety should be given full consideration in developing high yield production system in soybean.%大豆高产栽培体系的增产效果是不同栽培技术综合作用的结果,特定
