通过几年的试验,我们探索出一套适于干旱地区华北落叶松容器育苗技术,培育的苗木质量好,产苗量高,且生产的苗木可供春、夏、秋三季造林。一、种子消毒及催芽处理华北落叶松大田容器育苗一般采用春季播种,播前15天对种子进行消毒及催芽处理,种子要选发芽率65%以上的一级种子。消
After several years of experimentation, we explored a set of container seedling technology suitable for Larix principis-rupprechtii in arid areas. The nursery stock of nursery stock is good in quality and seedling yield is high. The seedlings can be used for afforestation in spring, summer and autumn. First, the seed disinfection and germination Larix principis-rupprechtii container seedlings are generally used in the spring sowing, 15 days before sowing the seeds for disinfection and germination treatment, the seeds should be selected germination rate of 65% or more of the first seed.
