摘要
为探讨不同抚育管理措施对杉木人工林的生长影响和效应,本研究在广西壮族自治区贺州市八步区黄洞瑶族乡开展不同抚育管理措施的杉木人工林生长小效应研究,通过分别设“抚育间伐+割灌”“抚育间伐”“割灌”3组不同抚育管理处理和1组不做抚育管理的对照组进行试验,并测定和比较试验后杉木人工林的树高、胸径、单株材积。试验研究发现,经过采取不同的抚育管理措施对杉木人工林进行连续抚育5 a后,在相同立地条件下各处理杉木人工的平均树高、胸径、单株材积均为差异极显著(P<0.01);与单纯抚育管理或单纯割灌的抚育管理方式相比,采用“抚育间伐+割灌”的方式杉木人工林的平均树高能增加2.87%、4.67%,平均胸径能增加6.35%、16.03%,平均单株材积能增加6.35%、16.03%。本试验研究采用不同抚育管理措施均对杉木人工林的生长有积极的影响效应。
In order to explore the effects and impacts of different nurturing management measures on the growth of Chinese fir planta-tions,this study conducted a small effect study on the growth of Chinese fir plantations with different nurturing management measures in Huangdong Yao Township,Babu District,Hezhou City,Guangxi Zhuang Autonomous Region.Three different nurturing management treatments,namely"nurturing thinning+cutting","nurturing thinning",and"cutting",and one control group without nurturing man-agement were set up for the experiment.The tree height,breast height diameter,and individual volume of Chinese fir plantations were measured and compared after the experiment.Experimental research has found that after adopting different nurturing management meas-ures for continuous nurturing of Chinese fir plantations for 5 years,the average tree height,breast height diameter,and individual vol-ume of Chinese fir plantations under the same site conditions showed significant differences(P<0.01)among the treatments;Com-pared with the simple nurturing management or simply cutting and irrigating nurturing management methods,the use of the"nurturing thinning+cutting and irrigating"method in Chinese fir plantations resulted in an average increase of 2.87%and 4.67%in tree energy,6.35%and 16.03%in average breast height diameter,and 6.35%and 16.03%in average individual volume.This experimental stud-y found that different nurturing and management measures have a positive impact on the growth of Chinese fir plantations.
