本文以翔实的数据分析了近15年来河北省大豆生产形势。分析认为:河北省大豆种植面积正以平均每年超过2.8万hm2的速度下降,已经从1993年的62.9万hm2降至2008年的20.3万hm2,下降了2/3,为建国以来的最低点;而大豆的单产水平却以平均每年5%的速度递增,单产水平已经超过2000kg/hm2;尽管如此,由于种植面积下降较多,大豆总产以平均每年约4.4万t的速度下降,从1994年的103.4万t降到了现在的38万t。文章还对全省近年的大豆种植分布、应用品种、新技术以及出现的高产典型进行了介绍。指出了大豆生产中存在的问题和技术需求,同时提出了今后河北省发展大豆生产应该采取的对策。
This article analyzes the production situation of soybean in Hebei Province in the recent 15 years with detailed data. The analysis shows that: the soybean acreage in Hebei Province is decreasing at an average rate of more than 28,000 hm2 per year, which has dropped from 629,000 hm2 in 1993 to 203,000 hm2 in 2008, down by 2/3, the lowest point since the founding of the People’s Republic; However, the yield per hectare of soybeans increased at an average rate of 5% per annum and the yield per unit area exceeded 2000kg / hm2. However, due to the large decrease in acreage, the total soybean yield decreased at an average annual rate of about 44,000 t from 1994 Of 1,034,000 t dropped to the current 380,000 t. The article also introduced the recent soybean planting and distribution, applied varieties, new technologies and high-yield typical in the province. Pointed out the existing problems in soybean production and technical needs, while the future development of soybean production in Hebei Province should take countermeasures.
