作者为刺槐萌芽和根蘖更新提供依据,在泰山北坡用标准地和标准木法,调查了两种起源刺槐林的生长。本文分析了调查结果,说明刺槐第一代萌生林生长量明显大于实生林;两种起源的林分中,30年生林木均有基部心腐现象,心腐率10%左右,萌生林稍高于实生林;在山地中层土条件下,培养刺槐中小径材,两种起源的林分均以30—35年主伐更新为宜。
The authors provide the basis for the germination of black locusts and the regeneration of root tillers. The growth of two originated locust forests was investigated on the northern slope of Mount Tai with standard and standard wood methods. This paper analyzes the survey results, indicating that the first generation of black locust forest growth was significantly larger than the real forest; two originated forests, 30-year-old trees have basal heart rot phenomenon, the heart rate of about 10%, slightly higher than the sprouting forest Real forest; middle mountain soil conditions, cultivating small and medium-sized parts of Robinia pseudoacacia, two origins of the forest are 30-35 years of the main cutting updates.
