细圆藤对杉木人工林生长干扰的研究
|
摘要
基于南宁市郊发现大片细圆藤缠绕杉木人工林的危害状,对细圆藤不同入侵时间的杉木林地进行调查,设置样地进行对比研究,分析杉木对细圆藤干扰生长和生理生态的响应,揭示细圆藤入侵对杉木的危害性。结果表明:各林分杉木胸径生长差异不显著,随细圆藤入侵时间延长,杉木树高和蓄积量受到显著影响,且林木死亡率增高,保留株数逐渐减少;各林分杉木的叶绿素含量、超氧化物歧化酶、过氧化物酶、过氧化氢酶、多酚氧化酶、抗坏血酸过氧化物酶5种酶活性均呈极显著差异,其大小排序均为生长良好的杉木纯林>被细圆藤干扰4年的杉木林分>被细圆藤干扰8年的杉木林分。而丙二醛含量显著升高,叶片膜质过氧化加重。杉木随细圆藤入侵时间延长,抗干扰的能力逐渐减弱,在人工林抚育中应及时清理林地内的细圆藤以促进杉木生长。
Based on the problem that Cunninghamia lanceolata plantation was wraped by Pericampylus glaucus around the suburb of Nanning,the investigation was conducted on C. lanceolata plantation by the time of invasion of P. glaucus,was set up contrast experiments to explore the effect of the inference on the growth and physiological ecology of C. lanceolata by P. glaucus. Results show that there is no significant difference in the growth of DBH between each forest stands. With the extension of the invasive time,the height and volume of C. lanceolata are significantly affected,and the mortality of forest trees increases,and the number of retained plants decreases. The chlorophyll content and activities of superoxide dismutase,peroxidase,catalase,polyphenol oxidase and ascorbate peroxidase of each forest stands are significantly different,ranking as pure-growing C. lanceolata > C. lanceolata stand which has been interfered with by P. glaucus for 4 years > C. lanceolata stand which has been disturbed by P. glaucus for 8 years. The content of dialdehyde is significantly increased,and the membrane oxidization of the leaves is aggravated. The invasive time of C. lanceolata with the vine is prolonged,and the ability of anti-interference is gradually weakened. In the cultivation of plantation,P. glaucus in the forest should be cleaned up in time to promote the growth of C. lanceolata.
