摘要
由于河北省的核桃生产目前还大多沿用实生繁殖和传统的粗放经营方式，所以产量低、品质差。现有大树中大致有丰产、潜在丰产和低产３种类型。要发展河北省的核桃生产，应该做好以下几方面的工作：首先是充分利用现有资源，提高核桃的产量和质量；二是加大发展优良品种的力度，建立良种核桃生产基地；三是注重发展本省的核桃优良品种。
In Hebei province,the traditional and extensive management of walnut culture is still being widely practiced,resulting in inferior quality and low yield per unit area.The existing adult walnut trees can be classified into three types:high,potentially high and low yields.To develop the walnut production in Hebei province,the following works should be done:(1)make full use of the present resource of walnut,increasing production and improving its quality;(2)speed up the extension of improved walnut varieties,and establish the base for reproducing improved varieties;(3)devote much attention to developing of the local improved walnut varieties in Hebei province.
