林木生育周期长,见效慢.开展林药间作,可以实现以短养长,互利双收.新宾县城郊公社砬咀大队,1974年开始在赤杨林间种辽细辛,1977年以后发展到50亩,平均每年纯收入7,652元.同时,赤杨生长良好,材积增长率达30～70%.林药间作应选阳性、深根系树种的阔叶林,间种喜荫、耐荫或半喜荫的药材,如细辛、五味子、黄芪、人参等.赤杨和细辛搭配就是林药间种的好形式.赤杨林应选生长快、稳定和抗性强的中、壮龄和近熟林.密度不够而又有培育木可留的次生林,也可间作药材,按留优去劣的原则,保留直径12～18厘米的目的树种,每亩30～40株,然后种植药材.
Forest long cycle of growth, with slow success .To carry out intercropping forest and medicine, can achieve short growth, mutual benefit and double income.Xinbin County suburbs commune Cunzui brigade, started in 1974 in the alder forest Liao Xushen, development after 1977 To 50 acres, the average annual net income of 7,652 yuan .At the same time, alder growth well, volume growth rate of 30 to 70% .Inulin intercropping should be selected positive, deep root tree species of broad-leaved forest, inter-species shade, shade or shade Semi-hi-yam herbs, such as Asarum, Schisandra, Astragalus, ginseng, etc ..
