通过对临夏中南部山区农田地埂不同立地营造的大叶柳、柽柳、柠条和沙棘生长量和鲜生物量调查,按薪炭林、饲料林、编织林进行经济效益分析,结果表明,地上部鲜生物量大叶柳最大,柽柳次之,沙棘、柠条最小。在地埂上单行栽植株距2m,则在100m长的地埂上可栽植大叶柳50株,3年可提供530根大叶柳编织材(平均枝长2.85m、枝径3.3cm)和鲜叶114kg,每年收入250元。
Through the investigation on the growth and fresh biomass of Dahurian willow, Tamarix chinensis, Caragana korskii and Hippophae rhamnoides collected from different sites of farmland in the mountainous area of central and southern Linxia, the economic benefits of fuelwood, feed forest and weaving forest were analyzed. The results showed that aboveground part Larix largest fresh biomass, tamarisk followed, seabuckthorn, kale minimum. In a single row planted on the ground 株 2m, then in the 100m long 埂 on the planted Larix 50, three years to provide 530 large willow braided timber (average branch length 2.85m, branch diameter 3.3cm) and fresh Leaf 114kg, annual income of 250 yuan.
