杉木是生长快、材质好的优良用材树种,历来深受群众喜爱。我省气候条件优越,适宜杉木生长的地方很多,但荒山营造杉木,由于整地和经营管理不尚等原因,也不易成林成材,往往长成小老树。1973年初我场采用2年生苗,在金平县城区附近的荒山上进行全垦、水平阶梯带垦和不垦的营造试验,面积共12亩。经过一年的观察,整地与不整地的幼树生长差异很大。全垦和带垦的幼树茎干粗壮,叶色青绿,未经整地穴塘定植的幼树苗干矮小纤弱,叶色黄绿。其生长量比较如下:
Cunninghamia lanceolata is a good timber species with fast growth and good material, which has always been favored by the masses. There are many places suitable for the growth of Chinese fir in our province, but there are many places for the growth of Chinese fir. However, due to the problems of land preparation and management, the growth of Chinese fir is not easy. At the beginning of 1973, I used 2-year-old seedlings and conducted full-scale cultivation on the barren hills near the urban area of Jinping County. With a total of 12 mu of land, they were cultivated with reclamation and reclamation without reclamation. After a year of observation, land preparation and growth of saplings vary widely. Reclamation and reclamation of the young stem sturdy stems, leaves green color, without plastic planting ponds Saplings dry short and thin, leaf color yellow-green. The growth is compared as follows:
