为研究马尾松(Pinus massoniana Lamb.)良种苗在资源县大面积推广造林的初步效果,使用正交试验设计研究马尾松良种苗造林成活率及高生长情况。选择研究影响的因素为:造林地的选择林地清理方式是否炼山,苗木类型选择为轻基质苗与裸根苗,造林时间为冬季与春季,定植坎为明坎或暗坎。研究结果表明:苗木类型对造林成活有显著差异,其它3个因素对成活无显著影响;各因素对当年苗木高生长无显著影响。为生产上营造马尾松造林提供了参考。
In order to study the preliminary effect of Pinus massoniana Lamb seed propagation in a large area in Resource County, the orthogonal design was used to study the afforestation survival rate and high growth condition of Pinus massoniana Lamb. The factors that influence the selection of the study are as follows: The choice of afforestation land Whether the way of clearing the woodland is the way of refining, the type of seedling is light and naked root, the planting time is winter and spring, and the planting ridge is Ming or Hom. The results showed that seedling types had significant differences in afforestation survival, and the other three factors had no significant effect on survival; each factor had no significant effect on seedling height growth in that year. It provides a reference for creating Pinus massoniana afforestation in production.
