拦截灌溉方式对毛竹林生长与土壤肥力的影响
Effects of Interception Irrigation Methods on the Growth of Phyllostachys edulis Forests and Soil Fertility
摘要
Abstract
Taking the Phyllostachys edulis(Mosobamboo)forests in Yong'an City,Fujian Province as the research object,three treat-ments were established:self-irrigation by rainfall interception(XLG treatment,no external water source),stump irrigation(YGK treatment,with external water source)and no interception or irrigation(ZCK treatment).The effects of these treatments on the growth indicators of the bamboo forest and soil fertility factors were analyzed,aiming to explore the soil conservation,water retention,fertility preservation functions,and management effectiveness of the self-irrigation method without an external water source.The results showed that among the three treatments,the average diameter at breast height(DBH),bamboo shoot yield,timber production,and ex-isting bamboo stock all followed the order:XLG treatment>YGK treatment>ZCK treatment.Significant differences were found in average DBH,spring shoot yield,and existing bamboo stock between each pair of treatments,but the differences in timber production were not significant.In the 0-20 cm soil layer,the soil bulk density of the XLG treatment differed significantly from that of the YGK and ZCK treatments,while the difference between YGK and ZCK was not significant.The XLG treatment also improved soil porosity,content of water-stable aggregates greater than 0.25 mm,soil structure destruction rate,and soil nutrients to varying degrees.Similar trends were observed in the 20-40 cm soil layer,although the magnitude of change was smaller.Comprehensive results indicate that in areas lacking irrigation water sources,implementing interception irrigation facilities in Moso bamboo forests can achieve the goals of increasing production,improving quality,and enhancing efficiency,while also saving energy,water and land.关键词
