半干旱地区野生平榛丰产栽培技术研究

High-yield Cultivation Techniques for Corylus heterophylla Fisch.in Semi-arid Area

朝阳市位于辽宁省西部,气候干旱少雨,是典型的半干旱地区,因为具有独特的气候条件,使大多数树种难以生长,而栽植面积较大的油松、杨树在生长过程易形成小老树,低产林改造成本很大,致使广大农民缺乏致富手段和途径。朝阳市野生榛子资源丰富,野生平榛具有抗寒耐旱,味香等特点,深受市场欢迎。但目前朝阳市的野生榛丛生产仍为原始粗放的经营管理方式,致使榛林的经济效益十分低下。为了使广大农民快速致富和拓宽致富渠道,我们对朝阳市野生平榛丰产栽培技术进行了探索和研究。总结出了改造辽西地区野生榛丛的方法,分别为:清理林地、调整疏密度、平茬更新。

Chaoyang city,located in the west of Liaoning Province,is a typical semi-arid region with dry weather and shortage of rain,and.Because of the unique climate condition,most species of trees cannot grow here.Pine trees and poplar trees planted are easily to become small and old trees.It costs a lot for the low production forest improvement.Chaoyang is rich with wild Corylus heterophylla Fisch.which is cold-tolerant and dry-resistant,popular in the market.Management of Corylus heterophylla Fisch.,however,is still at a lower level,with low economic benefits achieved.In order to explore a rapid approach to making farmers rich,high-yield cultivation techniques of Corylus heterophylla Fisch.were summarized with respect to site clearance,density moderation and stump cutting for regeneration.
