| 摘 要： | 在21年生、13地位指数的第1茬杉木林采伐迹地上,通过不炼山、保留杉木萌芽条、套种酸枣更新的5年生萌芽杉木酸枣混交林的生长状况与生物量进行了研究,结果表明:二茬萌芽更新的杉木酸枣混交林生长良好,杉木的平均胸径、树高、单株材积、地上部分单株生物量分别为5 6cm、4 5m、0 00817m3、4 788kg·株-1,与萌芽更新的杉木纯林相比,均略有提高,分别比杉木纯林增加3 70%、1 12%、3 29%、2 79%;混交林中酸枣的平均胸径、树高、单株材积、地上部分单株生物量分别为5 0cm、6 10cm、0 00754m3、3 787kg·株-1,除了平均高外,均小于杉木;混交林总蓄积量和乔木层总生物量分别为24 884m3·hm-2和13 32t·hm-2,分别是纯林的2 29倍和2 08倍。萌芽杉木与酸枣混交林是一种生产力较高的混交模式。

Preliminary Report on the Growth and Biomass of Sprout Cunninghamia lanceolata and Choerospondias axillaris Mixed Forest |
| |
| Abstract: | The results show that the second crop of Cunninghamia lanceolata and Choerospondias axillaris mixed forest with sprout regeneration grow fine,the average dbh,height,single tree volume and above ground portion single tree biomass of C.lanceolata are 56 cm,45m,000817m3 and 4788kg per tree respectively,which all increase slightly as compared with those of pure C.lanceolata forest with sprout regeneration and respectively increase by 370%,112%,329% and 279% as compared with those of pure Clanceolata forest;those of C.axillaris in the mixed forest are 50 cm,610m,000754m3 and 3787 kg per tree respectively,all smaller than those of C.lanceolata except the height of C.axillaris;the total mixed forest stocking and total arbor layer biomass are 24884 m3 per hm2 and 1332 t per hm2 respectively,229 times and 208 times as large as those of the pure forest respectively.The mixed forest is a mixed pattern whose productivity is relatively high. |
