不同密度对杉木林根际土壤丛枝菌根真菌群落结构及共生格局的影响特征1
Effects characteristic of different densities on arbuscular mycorrhizal fungal community structure and symbiotic patterns in rhizosphere soil of Cunninghamia lanceolata plantations
[目的]杉木是我国栽植面积最广的用材树种,阐明杉木根际土壤微生物特征,对通过密度调控科学间伐抚育经营杉木人工林有指导意义。为了明确根际土壤丛枝菌根真菌(AMF)对杉木林种植密度变化的响应特征。[方法]基于高通量测序,评估不同密度杉木根际土壤丛枝菌根真菌(Arbuscular Mycorrhiza Fungi,AMF)群落的多样性、结构和共生模式。[结果]从 1950株/hm2、2250株/hm2、2700株/hm2、3300株/hm2密度杉木林根…查看全部>>
[Objective]Cunninghamia lanceolata is the widely planted timber species in China.To elucidate the characteristics of rhizosphere soil microorganism of C.lanceolata is helpful for scientific thinning and tending of C.lanceolata plantation.To clarify the response characteristics of Arbuscular Mycorrhizal Fungi(AMF)in rhizosphere soil of C.lanceolata plantations to density change,and the relationship and mechanism of action with understory vegetation diversity.…查看全部>>
