根据我省干旱少雨和地形复杂多变的特点,容器育苗工作对我省造林事业的发展将起重要的作用。但目前国内尚找不到较完整的各种形状容器育苗试验的数据。为此,我们对不同形状的育苗容器进行了两年的育苗重复试验,以探索各种容器形状对苗木生长发育的影响规律,为设计合理结构的容器提供可靠的依据。一、试验材料(1)容器形状:主要指容器横断面的形状。试验的有以下八种:
According to the characteristics of drought and rainy days in our province and complex and changeable terrain, container seedling cultivation will play an important role in the development of afforestation in our province. However, at present, no more complete data on the seedling experiment of various shape containers can not be found in China. To this end, we conducted two-year nursery trials on different shapes of nursery containers to explore the influence of various container shapes on nursery stock growth and development, and provide a reliable basis for the design of containers with reasonable structure. First, the test materials (1) container shape: mainly refers to the shape of the container cross-section. The test has the following eight kinds:
