摘要
针对桤木播种育苗生产中存在成苗率低,生产成本高等问题,对桤木播种育苗的不同播种方式、播种时间、覆盖材料进行3因素3水平L9(34)正交试验,结果表明:采用撒播平压、3月中旬播种、薄膜覆盖是桤木播种育苗技术的最优组合。为桤木播种育苗生产,提供参考。
According to the problem on seedling off Alnus cremastogyne, such as low seedling rate, high production cost. The test orthogonal experiment L9 （3^4） was based on three factors and three levels on different seedling method, seedling time and cover material. The results were showed that： The best combination seedling method was using broadcast seeding flat press method, seedling in middle period of March and coverd by thin films. The seedling experiment results would take reference for seedling of Alnus cremastogyne.
