油松用营养杯育苗造林早在大跃进年代,我区有的社队就已应用。近几年来,在毛主席“绿化祖国”的伟大教导指引下,营养杯育苗造林发展很快。1975年全区制杯育苗2,200多万个,造林3万多亩,虽遇上天旱,但成活率仍达80%以上;1976年制杯育苗2,400多万个,造林5万亩,成活率达90%左右。几年来的实践证明,油松营养杯育苗造林是提高造林质量,加快绿化步伐的一种多快好省的办法,特别是对干旱、土层瘠薄的阳坡造林效果更为显著。 Pinus tabulaeformis with nutrition cup nursery Afforestation Back in the Great Leap Forward era, some communities in our area have been applied. In recent years, under the guidance of Chairman Mao’s “greening the motherland”, the nutrition cup nursery and afforestation has developed rapidly. In 1975, there were more than 22 million seedlings and more than 30,000 mu afforestation in the whole region. Although the drought was encountered, the survival rate still reached over 80%. In 1976, more than 24 million cup seedlings and 50,000 mu were afforested, with a survival rate of About 90%. Years of practice has proved that the seedling afforestation nutrition cup pine is to improve the quality of afforestation, to speed up the pace of greening a much faster and better way, especially for the arid, infertile alpine barren soil more significant effect.
