| 摘 要： | 对福建省宁化县方田乡泗坑村营造的7年生杉木毛竹混交林和杉木、毛竹纯林的林下土壤养分及林木生长量进行调查分析,结果表明:毛竹杉木混交林的土壤有机质、全氮、全磷、全钾、水解氮、速效磷、速效钾的含量均比毛竹纯林和杉木纯林高,毛竹杉木混交林中毛竹、杉木的平均胸径、平均高、枝下高、冠幅、单株材积生长量均比毛竹、杉木纯林高。表明,毛竹、杉木混交造林改善了土壤养分,促进林分的生长。

| Abstract: | Based on the investigation on the soil nutrient and forest growth amount of Cunninghamia lanceolata and Phyllostachys heterocycla pure forests and 7-year-old Cunninghamia lanceolata and Phyllostachys heterocycla mixed forest in Fangtian Township Siken Village,Ninghua County,the results showed that: the bamboo fir mixed forest soil organic matter,total nitrogen,total phosphorus,total kalium,hydrolysis phosphorus,rapidly-available phosphorus and rapidly-available kalium content of bamboo were higher than Phyllostachys heterocycla and Cunninghamia lanceolata pure forests,the average dbh,average height,height under branch,crown breadth,and individual volume growth were higher than Phyllostachys heterocycla and Cunninghamia lanceolata pure forests. |
