修枝对无瓣海桑人工林土壤特性的短期影响
Short-term Effects of Pruning on Soil Characteristics of Sonneratia apetala Plantation
摘要
Abstract
In order to investigate effects of pruning on soil characteristics of Sonneratia apetala plantation,and provide theoretical support for sustainable management of S.apetala plantation,20-year-old S.apetala planta-tion with uniform stand conditions was selected.Pruning treatments with three intensities(30%,50%and 70%)were set,with no pruning treatment as control.Soil physicochemical properties,and microbial community struc-tures and species diversities after two years of pruning were analyzed.Results showed that except for bulk den-sity and ammonium nitrogen content,pruning treatments had significant effects on other soil physicochemical properties.Compared with control,pruning treatments significantly decreased soil moisture content,cation ex-change capacity and total nitrogen content.Low-intensity and medium-intensity pruning treatments decreased soil bulk density.Low-intensity and medium-intensity pruning treatments significantly decreased soil organic matter content,and high-intensity pruning treatment significantly increased soil organic matter content.Prun-ing treatments had no significant effects on compositions of soil bacterial and fungal communities at phyla level.High-intensity pruning treatment significantly decreased species richness and evenness of soil microbes.There were certain correlations among soil physicochemical properties,and among soil physicochemical properties and soil microbes.Medium-intensity and high-intensity pruning treatments had greater effects on soil chemical properties.In short term,pruning treatments had certain effects on soil physicochemical properties,and micro-bial species richness and evenness.High-intensity pruning measure was not recommended in practice.关键词
