针对三江平原八五０农场低湿耕地湿、冷、硬、板、瘦是大豆高产的主要障碍因素，采用“沟、管、洞、缝”工程措施。以粮豆作物轮作周期为单元，以垅作深松为基础，建立土壤丰产库。应用“三垅”栽培技术进行增肥分层深施，降密提高匀度，实施良种、良法和大豆的经济学高产播期，在生物学播期之前这一研究成果与促控结合的配套技术措施，实现了大豆高产，为三江平原２０６７万ｈｍ２低湿耕地大豆中产变高产提供了配套栽培技术。
According to the wet, cold, hard, slab and thin skin of 855 farm in Sanjiang Plain, it is the main obstacle to the high yield of soybean, adopting the engineering measures of “ditch, pipe, hole and seam”. Taking the rotation cycle of grain crops as a unit and using subsoiling as a basis, a soil high yielding stock was established. Application of “three 垅” cultivation techniques for stratification of fertilizer stratification, densification to enhance the evenness, the implementation of good seed, good law and soybean economy high sowing date, before the sowing date of biological research and development and control of the package Technical measures to achieve a high yield of soybean, in the Sanjiang Plain 2 206 7 000 hm2 low-wet cultivation soybean middle high yield has provided a supporting cultivation techniques.
