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 high-yield soybean cultivation system is the result of the comprehensive effect of different cultivation techniques. The specific single technique shows the difference of yield increase due to the different planting areas and methods. The effects of different varieties, biological fungicides, neanine, leaf sprays and seed coating on the yield increase in the northern part of Heilongjiang Province were studied. The results showed that the yield potential of varieties and seed coating was higher. The yield of new varieties 1342 and 4404 increased by 10% and 6% respectively compared with that of local cultivars 711, mainly due to the difference of pods and grains per 100 grains. Seed coating yield 9.1%. Although different biocide agents could increase the dry matter accumulation during growth, only the biocide BRF-1 and pakchoi agents showed a 6% and 5% yield increase, and the spray-applied leaf spray at the first flowering stage increased 6.7% Herbicide injury and residue control agent Nai An no effect on soybean yield. Development of high-yielding cultivation of soybean technology system, it is necessary to consider the effect of increasing production, but also pay attention to environmental safety.
