大豆是黄淮海平原主要的粮油作物之一。为了发展大豆生产和建立夏大豆基地提供依据,本课题结合实验室测定和气候资料,采用对比分析的方法,对该区三个代表点北京(北部)、曲周(中部)、淮阳(南部)两年夏大豆的田间试验资料从生产力和生态适应性方面进行了分析研究,结果指出:黄淮海平原南部水浇地和旱地夏大豆生产力较高,尤以旱地的优势较为突出,发展大豆生产有潜力。相比之下平原北部发展大豆潜力较小,但在水浇地条件下,可适当发展夏大豆。
Soybean is one of the major cereals and oil crops in the Huang-Huai-Hai Plain. In order to provide a basis for the development of soybean production and establishment of summer soybean base, the subject combines laboratory measurement and climatological data with comparative analysis method to analyze the three representative points of Beijing (North), Quzhou (Central), Huaiyang ) Two-year summer soybean field trial data were analyzed from productivity and ecological adaptability. The results showed that the productivity of summer soybean in the south of Huang-Huai-Hai Plain and dry land were higher, especially in the dry land with potential. In contrast, there is little potential for the development of soybeans in northern plains, but summer soya may be developed properly under irrigated conditions.
