苗木是造林的物质基础,随着造林事业的发展,苗木生产必须相应地大力发展。因此,要拨出一部分农耕地来增加育苗面积。然而油松在农作茬地育苗,特别是在淡栗钙土地区和贫瘠的土地上初次育油松苗,往往不能获得良好地成效。为此,我们根据几年的试验研究和总结群众育苗的经验,对上述类型的新辟苗圃地进行油松育苗,提出以下几点育苗保苗的措施,以使油松育苗取得良好成效。 Seedlings are the material basis for afforestation. With the development of afforestation, nursery stock production must develop vigorously accordingly. Therefore, part of the farmland should be allocated to increase the nursery area. However, Pinus tabulaeformis nursery seedlings in cropping stubble, especially in the light chestnut soil areas and barren land for the first time pine seedlings often can not get good results. To this end, according to several years of experimental research and sum up the experience of mass nursery seedlings, nursery pine seedlings in these types of areas for the seedlings raised the following points nursery seedlings measures to achieve good results pine seedling nursery.
