摘要
２年试验结果表明：施用稀土浸种可提高针叶树场圃发芽率５．８％～３４．２％，阔叶树３１％～５０％，每公顷节省种子３．４８～１０．２６ｋｇ；叶面喷洒适宜的试验组合有促进苗木生长作用可提高成苗率２．０％～５０．７％；而且方法简单、使用方便，成本低。
T wo years experiment shows that can increase the nursery germination rate ofconifer tree 5.8～34.2% and broad一leaved tree 31～50% by seed soaking in rare earthsolution. This method also can save seeds about 3. 48～10. 26kg per hectare. By spryingleaf一surface,optimum combination in the experiment can accelerate the growth ofseedlings,and increase seedling survival rate 2.0～50.7%. The two methods is simple,convenient and low cost.
