杉木在我县南北二山均有生长,栽植历史较长。过去多用根孽法繁殖,产苗量小,满足不了大量种杉的需要。为了大力发展杉树加速基地建设、我县八里关公社从1976年开始用种子育苗。并有5个大队进行了山地育苗试验,当年苗高10厘米以上。1977年又在8个大队林场共育苗37.8亩,实现了苗全苗壮,为杉树山地育苗就地造林,加快建立以杉树为主的用材林基地起了示范作用。主要做法是:
Cunningham has grown in both northern and southern mountains of my county, planting a long history. In the past, more use of root evil law reproduction, seedling production is small, can not meet the needs of a large number of species of fir. In order to vigorously develop the construction of fir tree accelerating base, my county Bali commune since 1976 with seedling. And five brigades conducted a mountain nursery test, when the seedling height of 10 cm or more. In 1977, a total of 37.8 mu of seedlings were nursed on the eight brigade farms to realize the seedlings’ strong seedling capacity. They played an exemplary role in afforestation of seedling nurseries in the mountainous areas of Sugimoto and accelerated the establishment of a forested timber-based forest base. The main approach is:
