黑龙江八一农垦大学等九个单位组成的多学科联合攻关小组承担的国家“七五”重点科技攻关项目“低湿地大豆机械化高产栽培技术”课题,已于1990年2月15日通过黑龙江省科委鉴定,整体成果达国际水平。 三江平原低湿地总面积达2,180万亩,占总耕地面积的40％。其中,八五○农场示范区低湿易涝的耕地面积有36.4万亩,占八五○农场耕地面积的80.4％。这些低湿地有益微生物的生态环境恶劣,土壤承栽力差,机械化作业困难,严重影响大豆产量,历史上亩产
Heilongjiang Bayi Land Reclamation University and other nine units of the multidisciplinary joint research team assumed the national “Seventh Five-Year” key scientific and technological project “low-wetland soybean mechanization and high-yield cultivation technology” project, on February 15, 1990 through the Heilongjiang Province Branch Committee appraisal, the overall achievement reached the international level. Sanjiang Plain low wetlands total area of 21.8 million mu, accounting for 40% of the total cultivated area. Among them, the farmland area of low-humidity and flood-prone areas in the “360” farm demonstration area has 36.4 million mu, accounting for 80.4% of the farmland area of the 850 farmlands. These low-moisture beneficial microorganisms have poor ecological environment, poor soil bearing capacity, difficult mechanization operations and serious impact on soybean yield.
