黑龙江省栽培大豆的历史悠久,种植面积每年约在2000—2300万亩,是全国种植面积最大的省份,国家重要的大豆商品粮基地。 不同的品种在不同的生态条件下,经过长期自然选择和人工选择而形成了一定的生态类型。生态类型的分布有比较明显的规律性,这就可以进行不同的品种区划。品种区划可以明确服务范围和当地生态类型,有利于优良品种的选育和推广;有利于组织外贸出口和提高产量。因此,品种区划对指导生产和科研工作都有重要意义。 Heilongjiang Province has a long history of cultivation of soybeans, planting area of ​​about 2000-2300 acres per year, is the country’s largest planted province, the country’s major soybean commodity grain base. Different varieties under different ecological conditions, after long-term natural selection and artificial selection and the formation of a certain type of ecology. The distribution of ecological types have obvious regularity, which can carry out different species division. Variety zoning can define the scope of services and local ecological types, is conducive to the breeding and promotion of fine varieties; is conducive to the organization of export and increase output. Therefore, the regionalization of varieties to guide the production and research work are of great significance.
