我县位于大别山主峰天堂寨南麓,是杉木地理分布的北部边缘,山地土壤多属片麻岩发育的砂质壤土,较为贫瘠。全县杉木造林保存面积15万亩,有一部分由于土质瘠薄,生长势差,甚至呈“小老头”状。为了加速杉木生长,实现速生丰产,近几年来,在杉木培育管理上,我县广大林业职工和贫下中农在生产实践中摸索出抽槽压青,扩带培土抚育的方法,收到了很好的效果。1975年全县采用这种方法抚育杉树3.5万亩,为多快好省地发展杉木生产找出了新途径。 My county is located in the southern foot of Tiantangzhai, the main peak of the Dabie Mountains. It is the northern edge of the geographical distribution of Chinese fir. Most of the mountainous soil is sandy loam that is developed by gneiss, which is relatively barren. Fir trees afforestation throughout the county area of ​​15 mu, some due to infertility soil, poor growth, and even the “old man” shape. In order to accelerate the growth of Chinese fir and achieve fast-growing and high-yielding, in recent years, the majority of forestry workers and poor and middle peasants in our county have worked out the methods of cultivating and tending the soil by expanding the groove in the production practice, and have received very good effect. In 1975, the county used this method to raise 35,000 mu of Chinese fir trees and found a new way for developing fir production in a more efficient and economical manner.
