我场自1963年以来营造油松幼林8000多亩。近年来山地阳坡油松直播造林成活率达90％以上。不论采用何种方法造林,都要在造林前一年(或半年)进行整地,坑面要平,外沿要牢固。坑长1.2米,宽0.6米。坑内松土层20厘米左右,杂草、乱石要拣净。坑距1米,成品字形排列。为了提高造林成活率,可采用山地块状育苗:选择土层较厚的阴坡脚或沟塘废地进行条状整地,条宽1米, My field since 1963 to create more than 8,000 acres of pine trees. In recent years, the survival rate of direct seeding afforestation in mountain sunny slope reached over 90%. No matter what method of afforestation, afforestation should be carried out in the year before planting (or half a year), the pit surface should be flat and the outer edge should be firm. Pit length of 1.2 meters, 0.6 meters wide. Loose soil about 20 cm pit, weeds, rocks to pick net. Pitch 1 meter, finished glyph arrangement. In order to improve the survival rate of afforestation, mountainous nursery stock can be used: choose thicker shady soil foot or ditch wasteland for strip preparation, strip width 1 meter,
