摘　　要：2019年在山东省德州市黄河涯试验基地进行黄淮海夏大豆新品种圣豆18播期试验,旨在通过研究分析其植株干物质积累、分配特点及产量的田间表现,以充分发掘其增产潜力。结果表明,开花期、结荚期、鼓粒期和成熟期,6月15日播种的大豆单株干物质积累总量及各器官干物质积累量均最高;4个生育期干物质积累量最大的器官分别为叶片、茎、豆荚和豆荚,生育后期积累的干物质由叶片、茎等营养器官逐渐分配至生殖器官豆荚;6月15日播期大豆产量比6月5日及6月25日播期处理分别增产13.92%和22.63%。因此,黄淮海及相似生态区6月中旬播种该品种,有利于调动植株生长因素,促进干物质积累及分配,更大发挥其产量潜力。The sowing date experiment of a new summer soybean variety Shengdou 18 was conducted in the Huangheya test base,Dezhou City,Shandong Province to explore the yield increasing potential by analyzing the characteristics of dry matter accumulation and distribution in plants and yield performance in field.The results showed that at flowering,pod-setting,grain-filling and ripening stages,the total dry matter accumulation of individual plant and dry matter accumulation of different organs were all the highest when sowed on June 15,and the organs with the highest dry matter accumulation at the four stages were leaves,stem,pod and pod,respectively.At later stages,the accumulated dry matter in vegetation organs such as leaves and stem was gradually transfered into reproductive organ(pods).Compared with early and late sowing,the yield of soybean sowed on June 15 increased by 13.92%and 22.63%,respectively.It could be concluded that in the Huanghe-Huaihe-Haihe region and similar ecological areas,sowing Shengdou 18 in the middle ten days of June was beneficial to mobilizing positive factors of plant growth,promoting dry matter accumulation and distribution,and exerting the potential of soybean yield.
