刺槐(Robinia pseudoacacia)造林易成活,生长快,表层根系发达,能适应干旱的土壤。对大气的干旱适应力也很强。是一种耐干旱、瘠薄的用材林、水土保持林和薪炭林树种。多年来,我区低山丘陵区营造了三十余万亩刺槐林,但对其采伐期不一。为提高经济效益,充分利用资源,寻求刺槐最佳采伐更新期,我们于1986年5月对桑元涧林场刘家坨林区和域南庄林场场部刺槐进行了调查分析。其方法采用标准木树干解析,简述如下:
Robinia pseudoacacia afforestation is easy to survive, grow fast, surface roots developed, able to adapt to the arid soil. Resilience to atmospheric droughts is also strong. Is a drought-resistant, infertile timber forests, soil and water conservation forests and firewood species. Over the years, I hilly area to create more than 300,000 acres of acacia forest, but its logging period varies. In order to improve economic efficiency, make full use of resources, and seek the best harvesting period of Robinia pseudoacacia, we conducted a survey and analysis of Robinia pseudoacacia in Liujiatuo Forest Area and Duannanzhuang Forest Farm in Sangyuanjianlin Farm in May 1986. The method uses standard wood trunk analysis, summarized as follows:
