摘要
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,特定的单项技术因区域和种植方式不同而表现出增产的差异。研究探讨了不同品种、生物菌剂、奈安、叶喷剂及种衣剂在黑龙江省北部地区的增产效果。结果表明,品种和种衣剂增产潜力较高,新品种1342和4404的产量较当地主栽品种711,分别增产10%和6%,主要是荚数和百粒质量的差异。种衣剂增产9.1%。尽管不同生物菌剂均能增加生育期干物质积累,但只有生物菌剂BRF-1和保根菌剂表现出6%和5%增产效果,初花期喷施研制的叶喷剂增产6.7%,除草剂药害及残留防控剂奈安对大豆产量没有影响。制定大豆高产栽培配套技术体系,既要考虑增产效果,也要注重环境安全。
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.
