摘要:
 基于马尾松凋落叶难于分解的特性，选择菌剂、表面活性剂、不同碳氮营养液和有机肥料4种人工调控因素，采用正交试验设计（L934），在马尾松林下开展凋落叶分解定位试验，分析不同调控因素对凋落叶分解速率的影响。结果表明，‘菌剂’对凋落叶失重率和凋落叶分解系数均产生了显著性影响，腐解剂2的作用效果较好；‘有机肥料’对凋落叶分解系数影响显著，鸡粪表现较好；‘表面活性剂’可显著影响分解初期的凋落叶失重率，但作用效果有待进一步研究；‘不同形态氮的碳氮营养液’对凋落叶分解影响不显著。根据凋落物特性，选择适宜的多种调控因素联合作用是促进马尾松凋落叶分解的有效途径。
Abstract:
Pinus massoniana needle litter decomposes slowly.Improving nutrient return rate and maintaining the stability of soil fertility have been key issues in the sustainable forest management.A needle litter decomposition regulation test (L934) was carried out in P.massoniana forest with 4 kinds of regulation measures (applying microbial inoculants,surface active agent,carbon and different forms nitrogen nutrient solution and organic fertilizer).Impacts of different factors on the needle decomposition rates were analyzed.The results implied that ‘microbial inoculants’ exhibited significant impacts on the decomposition rate constant,in which the No.2 microorganism was the best.‘Organic fertilizer’ also demonstrated significant impacts on the decomposition rate constant,in which chicken manure showed good performance.’Surface active agent’ affected the decomposition rate between 0 and 60 days,and the functions needed to be further studied.The impact of ’carbon&nitrogen nutrient solution’ was not significant. It was the effective way by adopting integrated measures to accelerate the needle decomposition rate.
