为提高干旱、瘠薄、沙地及石质山的造林成活率,加快荒山绿化速度,应大力研究、推广营养袋育苗造林技术。去年,我场搞了油松营养袋育苗造林试验,取得了较好的效果。育苗面积40平方米,产苗约三万袋,造林60多亩,秋查成活率达90%以上。其做法是: 一、营养袋育苗 1、营养袋的制作:用64开报刊纸糊成直径4厘米、高8厘米的纸袋,每个工可糊1000—1200个。 2、营养土的配制:用捣细并过筛的老圃地的带菌土四份与优质猪圈粪一份混合拌
In order to improve the survival rate of afforestation in arid, infertile, sandy and stony mountains and speed up the afforestation of barren hills, we should vigorously study and popularize the technology of nursery and seedling afforestation with nutrition bags. Last year, I conducted a field of pine seedling nursery bags afforestation experiment, and achieved good results. Nursery area of 40 square meters, about thirty thousand bags of seedlings, afforestation 60 acres, autumn check the survival rate of more than 90%. The practice is: First, nutrition bags nursery 1, the production of nutrition bags: with 64 open newspapers parchment into a diameter of 4 cm, 8 cm high paper bag, each worker can paste 1000-1200. 2, the preparation of nutritious soil: with pound and sieve the old nursery with four copies of contaminated soil and high-quality pig manure mixed
