捷克斯洛伐克发明了既可节约林木种子,又可降低育苗成本的纸膜胶贴育苗法。1981至1982年在50个苗圃中进行了田间试验。其方法是:先把种子按固定距离胶贴在水溶性纸膜上,然后把纸膜平铺在土壤上。为此还设计了专用机械,种子胶贴密度一般为2000—3000粒/m~2。用一般播种法培育云杉苗,平均每公斤种子产苗4000株,占所播有发芽能力种子的16.5％,而用纸膜胶贴法培育云杉苗,每公斤种子可产苗8000株,占所播有发芽能力种子的65.7％。
Czechoslovakia invented the paper-based seedling nursery method which can save tree seeds and reduce the cost of nursery. Field trials were conducted in 50 nurseries from 1981 to 1982. The method is: First, the seeds at a fixed distance affixed to the water-soluble paper film, and then the film tiled in the soil. To this end also designed a special machinery, seed paste density is generally 2000-3000 / m ~ 2. Spruce seedlings were cultivated by the general sowing method, with an average of 4000 seedlings per kilogram of seedlings, accounting for 16.5% of the seed germinated, whereas the seedlings of spruce seedlings were cultured with a paper film adhesive paste, Accounting for 65.7% of the seed germinated.
