Abstract:
Sowing date is an important approach for soybean high-yielding culture.Influences of three late sowing dates（June 4，2008，June 14，2008 and June 24，2008 with normal sowing date（May 7，2008）as control on soybean phenology，root，dry matter and fresh yield were examined.Late sowing shortens growing period significantly，the later the sowing date，the shorter the duration from sowing to emergence.Late sowing enhances vegetative growth，increases dry matter accumulation，while both root surface area and root length of seedlings are reduced，the ratio of root/shoot is decreased as well.Compared with normal sowing date，late sowing also increases above ground dry matter accumulation，and highest dry matter of 51.1 gplant-1?is obtained at R6 stage with sowing date in June 14，2008.Appropriate late sowing is good for yield formation in vegetable soybean，and June 4 to June 14 is the best sowing time for vegetable soybean in Harbin.
