通过对杉木(Cunninghamia lanceolata)普通林分幼龄期中选目标树采取劈草、翻土、施肥、修枝的综合培育措施,发现处理3a后不同坡位监测样地总蓄积量及其连年生长量较与对照样地的蓄积增长量分别提高了50%和30%以上,监测样地目标树蓄积量及其连年生长量则较对照样地分别提高了50%~70%和30%~160%;监测样地总蓄积量和目标树蓄积量连年生长量在处理第1年、第2年、第3年表现出先增强后减弱的趋势。研究结果对杉木目标树经营技术具有较好参考价值。
Through the comprehensive cultivation of the selected tree species of Cunninghamia lanceolata young seedlings, we found that the total stock volume and the annual growth rate Compared with the control plots, the accumulative increment of the target plots increased by 50% and 30%, respectively. The target tree accumulations and annual perennial growth of the plots increased by 50% -70% and 30% -160% ; The total amount of accumulation of monitoring plots and the amount of annual accumulation of target trees showed the trend of first increasing and then decreasing in the first year, the second year and the third year. The research results have good reference value for the management technology of Chinese fir target tree.
