摘要
研究了地膜控草、全垦抚育、带状抚育、穴块抚育等不同抚育方式对木荷和杉木幼树生长的影响.结果表明:抚育措施能促进木荷和杉木幼树植株树高、地径和冠幅的生长,不同抚育方式对木荷和杉木幼树平均树高、地径、冠幅的影响均表现为地膜控草>全垦抚育>带状抚育>穴块抚育>未抚育(对照).与林业生产上常用的全垦抚育方式相比,采用地膜控草抚育 3 年后,木荷平均树高、地径和冠幅生长量分别比全垦抚育方式提高 9.49%、12.64%和 17.20%,杉木平均树高、地径和冠幅生长量分别比全垦抚育方式提高4.74%、19.30%和9.60%,3 年的抚育成本下降 18.44%,实现了木荷杉木混交林的优质高效栽培.
Abstract
The effects of different tending measures such as grass control by plastic film,full cultivation tending,strip tending,and hole block tending on the growth of young trees on the mixed forest of Schima superba and Cunninghamia lanceolata in the mountainous area of northwestern Fujian Province.The results showed that tending measures can promote the growth of tree height,ground diameter,and crown width of young trees of S.superba and C.lanceolata.The effects of different tending methods on the average tree height,ground diameter,and crown width of young trees of S.superba and C.lanceolata were as follows:plastic film control>full cultivation tending>strip tending>hole block tending>no tending(control).Compared with the commonly used full cultivation method in forestry production,the use of plastic film controlled grass cultivation for 3 years increased the average tree height,ground diameter,and crown width growth of S.super-ba by 9.49%,12.64%,and 17.20%,respectively.The average tree height,ground diameter,and crown width growth of C.lanceolata in-creased by 4.74%,19.30%,and 9.60%,respectively,compared to the full cultivation method.The three-year cultivation cost decreased by 18.44%,achieving high-quality and efficient cultivation of S.superba and C.lanceolata mixed forest.
