【摘要】 中国大豆供求失衡,振兴大豆产业势在必行。北方大豆正面临单位土地产出率低带来的土地竞争不力、产销分离引起的成本增加、大面积重迎茬种植带来的减产严重、含油率和蛋白质含量不高等不利因素,限制了进一步发展。套作大豆作为南方新型早地多熟种植模式的主体作物,具有与主要粮食作物和谐共存、发展空间大,蛋白质含量高、利于食用和加工业的发展,减轻季节性干旱的危害、实现抗旱增收等优点和具大发展潜力。作者认为稳定北方大豆面积,提高单产,大力发展南方套作大豆是振兴我国大豆产业的必然之路。更多还原

【Abstract】 China’s soybean is out of balance between supply and demand.It’s urgent to revitalize the industry of soybean.Northern soybean is limited to make a further progress because of such negative factors as follows:the weak competition of soil caused by the low output of unit soil,the rise in cost owing to the separation of production and marketing,the grave low production caused by a large planting area of continuous and alternate cropping,the low rates of oil and content of protein.Relay-planting soybean,as the major crop in dry land and multi-ripe of new plant mode in the south,has many obvious advantages and deep potentialities such as:the ability of harmony and compatibility with major cereals,the more potential to improvement,the high content of protein, benefiting the development of food and machining industry,alleviating the hazards of seasonal drought, resisting drought and increasing money.The author firmly maintain,the necessary way to revitalize our national soybean industry is that to stabilize the area of northern soubean,improve the single production and strongly develop relay-planting soybean in south.更多还原
