进行火炬松、湿地松等国外松大田育苗,常因圃地选择不当,催芽、播种等环节掌握不好,以及病、虫、雀、鼠等危害,影响产苗量和苗木质量;且采用裸根苗造林,成活率低。因此,迅速研究出提高育苗成苗率和造林成活率的有效方法,乃是我省进一步推广国外松这个优良树种的重要技术关键之一。 采用容器苗造林,国外应用广泛。我国也有报导,南方雨量充沛的地区和北方干旱地区,均有用营养杯、营养砖育苗造林成功的事例,惟我省研究尚少。因此,我们为了探索在我省自然条件下国外松容器育苗造林的方法,自今年2月份开始,进行了火炬松、湿地松等容器育苗试验,共育苗8800多株(图1),并于8、9月间 To carry out loblolly pine, pine and other foreign pine nursery seedlings, often due to improper selection of nursery, germination, seeding and other aspects of poor control, as well as diseases, insects, birds, rats and other hazards, affecting seedling production and nursery stock quality; and nude Root seedlings afforestation, survival rate is low. Therefore, the rapid development of seedling raising rate of seedlings and afforestation survival rate of effective methods, but also our province to further promote this excellent tree species of pine one of the important technical key. Container seedlings afforestation, a wide range of foreign applications. Our country has also reported that in the areas with abundant rainfall in the south and the arid areas in the north, there are examples of successful use of nutrition cup and nutrition brick for seedling and afforestation. However, there are still few studies in our province. Therefore, in order to explore the method of seedling afforestation abroad in our province under natural conditions, we started the seedling experiment of Pinus tabulaeformis and Pinus elliottii from February this year. There were more than 8800 nursery plants (Figure 1) September
