在四川盆地通过引进国内外薪材树种和选择乡土薪材树种,进行栽植密度、始伐年龄、轮伐期等试验研究,结果表明:从引进的8个新材树种中,选择出任豆为适宜生长的树种,新银合欢、黑荆、荆为为适宜部分地区生长的树种;从13个乡土薪材树(草)种中筛选出桤木、刺槐、麻栎、栓皮栎、马桑、卵花甜茅等为比较优良的薪材树(草)种。桤木、刺槐、马桑等薪炭林的合理造林密度为10000株(丛)/ha;麻栎、栓皮栎为6000~7000株(丛)/ha;印花甜茅以行距1m为宜。桤木、刺槐、麻栎、栓皮栎等薪炭林,始伐年龄不超过5年,轮供期3~6年;马桑薪炭林始伐年龄为3~4年,轮伐期2~3年、印花甜茅栽植1年后平茬,以后每年采收。合理的造林密度、始伐年龄、轮伐期,能使选择的几个树种提高生物产量1.0~2.5倍。
Through the introduction of domestic and international firewood species and the selection of native fuelwood species in Sichuan Basin, the planting density, initial cutting age and rotation period were studied. The results showed that suitable selection of beans was suitable for the eight new timber species introduced The tree species that grow, the new Acacia, black Jing, Jing for suitable growth in some areas of the tree species; selected from the 13 native wood species (grass) alder, Robinia pseudoacacia, Quercus variabilis, Quercus, Tamarindus flowers for the more excellent fuelwood (grass) species. Log plantation, Robinia pseudoacacia, Marsh and other firewood forest planting density of 10000 plants (clumps) / ha; Quercus, Quercus variabilis 6000 ~ 7000 plants (clumps) / ha; Alnus cremastogyne, Quercus acutissima, Quercus variabilis and other fuelwood forests, the initial cutting age of not more than 5 years, the rotation period of 3 to 6 years; Marchant firewood forest beginning of the cutting age of 3 to 4 years, rotation period of 2 to 3 years , Printed Tamarix planted 1 year after stubble, after each harvest. Reasonable afforestation density, initial cutting age, rotation period, can make the selection of several species to improve biological yield of 1.0 to 2.5 times.
