刺槐(Robinia pseudoacacia L.)根系发达、萌蘖性强,适于采取根蘖更新,而且这种方法简便,成本低,幼林生长也快。目前我场刺槐成林面积2.8万亩,蓄积量10万余立方米.自1976年以来,已开始小面积采伐,为了提高更新效果,我们探讨了中层砂壤土较干旱瘠薄立地条件下,刺槐根蘖更新的合理密度,自1977建立标准地,定期进行生长量测定。现将试验结果整理如下,仅供参考。
Robinia pseudoacacia L. has a developed root system with strong sprouting and is suitable for root-shoot renewal. Moreover, this method is simple, low-cost and fast-growing. At present, the acreage of Robinia pseudoacacia is 28,000 mu and the stock volume is more than 100,000 cubic meters. Since 1976, a small area harvesting has started. In order to improve the regeneration effect, we have studied the relationship between Robinia pseudoacacia Tillers update the reasonable density, established since 1977, regular determination of growth. The test results are summarized below, for reference purposes only.
