在伟大领袖毛主席关于“绿化祖国”的伟大号召下,我县从1966年开始进行飞播造林。六年来,飞播造林172.8万亩。去年上半年普查了1966年至1970年飞播的109.1万亩林地,保存率达63%,较好的播区平均每亩有苗500株以上,一般播区平均每亩有苗260株左右。飞播造林是加速绿化荒山的好办法,既节省劳力,又能降低造林成本。从测量设计到播种作业每亩只用0.02工,成本0.6元(包括种子、人工、飞行费);而同树种人工造林则每亩需1.3工,成本1.2元。
Under the great call of Chairman Mao, the great leader, on “greening the motherland,” my county started the aerial seeding operation in 1966. In the past six years, 1,782,000 acres have been planted for afforestation. In the first half of last year, 1,091,000 mu of forest land was sown by aerial surveys from 1966 to 1970 with a preservation rate of 63%. The average area of seedlings per mu is more than 500, with an average area of about 260 per acre. Aerial seeding afforestation is a good way to speed up greening barren hills, which not only saves labor but also reduces afforestation costs. From measurement and design to sowing, it only cost 0.02 yuan per acre and the cost is 0.6 yuan (including seeds, artificial and flying fees). However, the artificial afforestation with the same tree needs 1.3 workers per mu and the cost is 1.2 yuan.
