根据黑龙江垦区大豆宽台栽培联网试验，以及大豆根系活性在土壤中的动态分布研究，优化了大豆的施肥位置。宽台施肥位置为：①种肥分散在种下２ｃｍ左右，占总肥量的１／４～１／３，用于催苗和壮根；②基肥施在台上植株行间，深度为５～１５ｃｍ，距两侧主根１５ｃｍ左右，占总肥量的２／３～３／４，用于提高花期、结荚期、鼓粒期的供肥强度
According to the Soybean Broad-band Cultivation Networking Experiment in Heilongjiang Reclamation Area and the dynamic distribution of soybean root activity in the soil, the fertilization position of soybean was optimized. Wide platform fertilization position: ① kinds of fertilizer dispersed in the planted about 2cm, accounting for 1/4 ~ 1/3 of the total amount of fertilizer used to promote seedlings and strong roots; ② base fertilizer applied to the stage plant rows, a depth of 5 ~ 15cm, about 15cm away from the main roots on both sides, accounting for 2/3 ~ 3/4 of the total amount of fertilizer, used to improve the flowering, podding,
