摘要
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 paper detailed analysis the situation in soybean production in Hebei Province by the data in the late 15 years.The paper considers：Soybean acreage in Hebei Province is at an average annual rate of more than 2.8 million hectares decline,from 62.9 million hectares in 1993 fell to 20.3 million hectares in 2008,reduced by two thirds,for the lowest points since the founding of New China;and soybean Yield levels are at an average annual rate of 5% increase,yield level has more than 2000kg per hectare.However,due to larger decrease in planted area,total production of soybean at an average annual rate of about 4.4 million tons to decline,from 103.4 million tons in 1993 fell to the present 38 million tons.The article also introduced the distribution of the province soybean planting and application types,new technologies and the emergence of a typical high-yield.Pointed out the problems in soybean production and technology needs,while proposals for future development of soybean production in Hebei Province should take countermeasures.
