1代杉木采伐剩余物对2代杉木生长的影响

Effects of Logging Residue Treatments of The First-Generation Cunninghamia lanceolata on the Growth of Second-Generation Stands

在福建省南平峡阳国有林场,研究1代杉木采伐剩余物不同处理方式对2代杉木生长的影响。结果表明:BL3处理(收获树干和树皮、加倍采伐剩余物)的10年生2代杉木林生长最好,其次为BL1处理(全树收获)、BL2处理(收获树干和树皮,不炼山)和BL0处理(收获地上所有有机质);而SB处理(收获树干和树皮,炼山)的杉木生长最差,炼山处理杉木蓄积量仅为不炼山的87.86%。

The effects of logging residue treatments of the first-generation Cunninghamia lanceolata on the growth of 10-year-old second-generation Cunninghamia lanceolata plantations were studied in Xiayang State Forest Farm,Nanping,Fujian Province.The results showed that the Cunninghamia lanceolata stand grew the best with the double slash treatment(BL3),followed by the whole tree harvest treatment(BL1),no slash burning treatment(BL2) and the above-ground organic material achievement treatment(BL0),and the poorest with the slash burning treatment(SB).Standing volume of the slash burning treatment(SB) was only 87.86% of the no slash burning treatment(BL2).
