为了提高火炬松在山东南部地区的造林成活率,采用了容器育苗。容器共分两类9 种规格。试验表明:不同容器规格对火炬松苗高、地径生长均有明显影响(1 年生苗高比0-5 年生苗高差异显著) 。容器规格大小与苗木生长量大小呈正相关关系。大容器培育的2 ～3 年生苗,绿化栽植成活率达90 % 以上,保存率85 % 以上。
In order to improve the survival rate of Pinus taeda in the afforestation of southern Shandong, container seedling was used. Containers are divided into two types of 9 kinds of specifications. Tests showed that different container specifications had significant effects on height and diameter growth of Pinus tabulaeformis seedlings (1-year-old seedling height was significantly different from 0-5-year-old seedling height). Container size and the size of seedlings growth was positively correlated. Large container breeding 2 to 3 years old, green planting survival rate of 90% or more, the preservation rate of 85% or more.
