白干土造林难度大,成活率尤其是保存率低。本文通过对白干土造林地采取特殊整地方式,分析特殊整地方式对土壤含水量、有机质含量、树木高生长和根系生长的影响,进而得出结论:特殊整地法—深耕、回填表土、置换钙积层,可以增加土壤的含水量和有机质含量,提高造林的成活率和保存率。
White dry soil afforestation difficulty, survival rate, especially the preservation rate is low. In this paper, by taking a special land preparation for the afforestation of white dry soil, the influence of special land preparation on soil moisture content, organic matter content, tree height growth and root growth was analyzed. The conclusion was reached that special soil preparation method - deep plowing, backfilling topsoil, Layer, can increase soil moisture and organic matter content, improve the survival rate and preservation rate of afforestation.
