杉木、檫木均为南方速生用材树种。在江苏、广东、四川,湖北等省进行杉、檫混交栽植效果很好,1975年以来,我们在新县陡山河乡的武占岭林场进行了杉、檫混交栽培试验。试验地设在武占岭林场场部附近。海拔390米,东南坡向,黄沙壤土,PH值6.5,年降水1522.8毫米,年平均温度14.6℃。试验采用7杉3檫,8杉2檫和杉木纯林对比试验。每亩189株,试验苗木为本场一年生播种苗,造林前沿等高线进行抽槽整
Chinese fir, alder are the fast growing timber species. In Jiangsu, Guangdong, Sichuan, Hubei and other provinces to carry out the cunninghania hybrid planting effect is very good, since 1975, we Xinzhan Doushanhe Wuzhanling forestry were fir and mixed cultivation experiments. Experimental site located in Wuzhanling field near the field. 390 meters above sea level, southeast slope, yellow sandy loam, PH value of 6.5, annual rainfall of 1522.8 mm, the annual average temperature of 14.6 ℃. The experiment uses 7 fir 3 檫, 8 fir 2 檫 and fir pure forest comparative test. 189 per acre, the experimental seedlings planted seedlings for the field annual planting, forestry along the contour of the slot trough
