杉木凋落物对土壤生物群落结构的影响研究进展
Research progress on the influence of Chinese fir litter on soil biological community structure (1.College of Forestry,Fujian Agriculture and Forestry University,Fuzhou,Fujian 350002,China;2.Chinese fir engineering technology research center of national forestry and grassland bureau,Fuzhou,Fujian 350002,China;)
为解决杉木大量连续栽培导致杉木林土壤质量衰退的问题,本文从杉木凋落物对其林下的土壤微生物种群的丰度、土壤微生物群落结构、土壤酶特性、土壤动物方面的相互影响进行探讨,进一步揭示凋落物及其土壤生物对杉木生长的影响作用,为杉木人工林合理经营提供一定的参考。国内外有不少凋落物对杉木人工林长期生产力保持的相关研究,但是多局限于凋落物自身的输入对土壤的影响,杉木凋落物对土壤生物的丰度、群落、活性的影响研究相对还较少,而且受地理位置的影响。而杉木土地质量的恢复…查看全部>>
In order to solve the problem of soil quality decline caused by a large number of continuous cultivation of Chinese fir,this paper discusses the interaction of Chinese fir litter on the abundance of soil microbial population,soil microbial community structure,soil enzyme characteristics and soil animals under the forest,and further reveals the influence of litter and soil organisms on the growth of Chinese fir,which provides certain reference for the rationa…查看全部>>
