摘要:: 分析大豆粒重降低的原因。找出生产中存在的问题，指导今后的生产实践。最主要原因是气候，春旱影响出苗情况，产生二、三类苗，长势不齐，长势弱；中后期低温寡照，影响干物质积累；北部早霜，中部涝灾对粒重的影响也比较严重；由于干旱封闭除草效果不佳，草苗齐长；以及除草剂药害对大豆粒重生产影响。

Abstract:: The reasons for the decrease of soybean grain weight were analyzed. Find out the existing problems in production and guide the future production practice. The main reason is the climate, spring drought affects the emergence of seedlings, two, three types of seedlings, growth is uneven, weak; Low temperature and low irradiation affect dry matter accumulation in middle and late stage. The effects of submergence on grain weight were also serious in the northern and central areas. Due to the drought closed weeding effect is not good, grass seedling qi long; And the effect of herbicide on the production of soybean grain weight.
