1 实施大豆工程条件分析我省不但具有大豆生产得天独厚的自然条件和发达的经济优势,而且具有其他省份不可相比的有利因素,有条件建设成为全国高产优质的大规模大豆生产基地。一是自然条件适宜发展大豆生产。我省地处高纬度,气候冷凉,适应大豆生长的面积约在733万 hm~2左右,按40%的种植面积,可种植大豆300万 hm~2。大豆种植面积历史上最高的1993年已达到297万 hm~2。我省土壤有机质含量较高,一般在2%～3%,新开发的
1 Analysis of the implementation of soybean engineering conditions The province not only has the natural conditions and well-developed economic advantages of soybean production, but also with other provinces can not be compared to the favorable factors, the conditions for building a high-yield large-scale soybean production base. First, natural conditions suitable for the development of soybean production. The province is located in the high latitudes, the climate is cool, and the area adapted to the growth of soybean is about 7.33 million hm ~ 2. According to the 40% planting area, 3 million hm ~ 2 soybean can be planted. The highest soybean acreage in history reached 2.97 million hm 2 in 1993. Soil organic matter content is high in our province, generally 2% to 3%, newly developed
