摘要/Abstract

摘要： 以黑龙江省东北林业大学帽儿山实验林场尖砬沟森林培育实验站23a生水曲柳落叶松带状混交林为研究对象,测定对落叶松林带进行不同方式结构调整后水曲柳林带土壤理化性质的变化。结果表明:不同结构调整方式,对水曲柳林带土壤物理性质未产生显著影响,对土壤部分化学性质影响显著。去边行调整后水曲柳林带土壤,上层和中层的水解N含量显著大于其它调整及对照组对应层次的含量(P＜0.05),上层的有机质含量也明显大于其它调整及对照组的含量(P＜0.05)。对落叶松去边行与隔株去株和品字型均匀伐相比,去边行表现出更好的改土效果。

Abstract: Our study objects were 23-year-old stands of ash and larch in Jianlagou silviculture experimental station,Maoer Mountain Test Forestry Farm,Northeast Forestry University,Heilongjiang Province.The changes of soil physical and chemical properties in ash stand were measured,after the structure readjustment in larch stand in different ways.The result showed that the effects on soil physical properties in ash stand were not significant,and the effects on some soil chemical properties significant,after the structure readjustment in larch stand in different ways.Under adjustment of thinning the border row,soil hydrolysable nitrogen of upper layer and middle layer was larger than the same layer under other adjustments and no adjustment(P＜0.05),and soil organic matter of upper layer was largest too(P＜0.05). Compared with adjustment of cutting one and reserving another one in a row,and adjustment of cutting half trees evenly in an area,the effects on soil in ash stand under adjustment of thinning the border row,were better.

Key words: ash, larch, mixed stand, restructuring, soil, physical and chemical properties
