西南桦穴盘容器工厂化育苗造林生长状况分析

测定一年生穴盘容器工厂化育苗与常规化育苗的西南桦植株的树高、地径、冠幅、成活率和病虫害。通过相关性分析，明确了树高、地径、冠幅三个性状之间存在显著相关性；多重比较表明穴盘容器工厂化育苗与常规化育苗植株树高、地径表现存在显著性差异；通过生长情况具体分析，表明穴盘工厂化育苗植株树高表现比常规化育苗植株表现优良，成活率也比常规化育苗高。说明穴盘容器工厂化育苗比常规化育苗造林表现优秀，以后西南桦造林应采用穴盘容器工厂化育苗的苗木。

Growth of Betula alnoides Planted with Holed Plate Contanier seedling

The height, diameter, crown width, survival rate, disease and insect pests were observed of the Betula alnoide both planted with holed plate contanier seedling and commonly seedling. Correlation were analysised among those characters, which show height, diameter, crown width were closely relationship. The reasult of Multiple Comparison showed the growth was remarkably different between two kinds of trees planted with holed plate contanier seedling and commonly seedling, the growth and survial rate of trees planted with holed： plate contanier seedling were much better than the latter. It could be concluded that trees planted with holed plate contanier seedling is much better than that with commonly seedling.
