樟子松是阳性、速生的针叶常绿树种,具有抗寒、耐旱、耐瘠薄、不苛求土壤条件等特性,是我省西部沙土地区造林的主栽树种。但多年来,仍存在着成活率和保存率低的问题。其主要原因:一是气侯条件差,风大寡湿,幼小植株因生理干旱致死。二是裸根苗造林,因根系风干失去生机而降低成活率。 为提高干旱沙地樟子松造林成活率和保存率,1981年我们在泰来县克利公社开始用塑料袋做容器育苗,在雨季造林,效果很好。又于1983年分别用培育一、二、三年的容器苗进行雨季造林试验,秋后调查其成活率,
Pinus sylvestris is a positive, fast-growing evergreen coniferous species, with cold, drought, barren, not demanding soil conditions and other characteristics, is the main planting species in the western sandy areas afforestation. However, over the years, there are still problems of low survival rate and preservation rate. The main reasons: First, poor climatic conditions, the wind was too damp, young plants died due to physiological drought. Second, bare root seedlings afforestation, due to loss of vitality root dry and reduce the survival rate. To improve the survival rate and preservation rate of Pinus sylvestris plantation in arid sandland, in 1981, we began to use the plastic bag as container seedling in Kaili County, Tailai County, afforestation in the rainy season, the effect is very good. Again in 1983, respectively, to cultivate one, two, three years of container seedlings rainy season afforestation test, after the investigation of its survival rate,
