油松直播造林鸟兽危害严重。为解决这一难题,太原市劳动模范、清徐县高白公社党委副书记桑石宝同志,经过多年摸索,反复试验,于1976年用油松籽加胶水拌六六六雨季直播造林成功。1977、1978年再次验证,都获得成功。1979-1981年在全公社进行大面积推广。三年来,共直播造林25,141亩,出苗率都在95%以上,现在保存面积有15,000多亩。1979年直播造林9,696亩,现保存9,000余亩。1980、1981年由于苗期受旱严重,造林保存面积比较低。经省、市有关领导和技术人员的鉴定,证明油松籽加胶水拌六六六粉直播造林,方法简便,成本低廉,在雨水正常年份,成活率可达90%以上,是加速绿化荒山的有效办法
Pine trees broadcast afforestation birds serious harm. In order to solve this problem, Taiyuan labor model, Qingxu Gaobai commune party secretary Sang Shibao comrades, after years of groping, repeated tests, in 1976 with pine oil plus glue mixing 666 rainy season direct seeding success. 1977, 1978, again verified, have been successful. From 1979 to 1981, large-scale promotion was carried out in the whole commune. In the past three years, a total of 25,141 mu of afforestation has been broadcast on a total of more than 95% of the germination rate. Now, 15,000 mu of preserved land has been preserved. 9,696 mu of afforestation was broadcast live in 1979 and more than 9,000 mu are now saved. In 1980 and 1981, due to severe drought in seedling stage, the area for reforestation was relatively low. The provincial and municipal leaders and technical personnel appraisal, proven pine nut plus glue mixing six six six live powder afforestation, the method is simple, low cost, in normal years of rainwater, the survival rate of up to 90%, is to accelerate the afforestation Effective method
