摘　　要：研究不同人工接种根瘤菌处理对马占相思幼林树高、胸径、平均立木单株材积及林地土壤营养元素含量的影响。结果表明:接种不同根瘤菌的马占相思林木,其树高、胸径和平均立木单株材积均高于对照,其中平均树高、胸径处理间差异显著,平均立木单株材积差异不显著,以接种HM8对幼林促生效果最佳;不同根瘤菌接种处理对马占相思幼林土壤有机质及营养元素含量的影响,表现为速效P>有机质>速效N>速效K,6种根瘤菌总体表现效果为HM8>ZG4>HM4>ZG3>HJ7>HJ6。Effects of inoculating different rhizohium on height,diamete,individual standing volume and soil nutrition elements of Acacia man- glum young trees were investigated. The results showed that,after inoculating different rhizobium, the height, diamete and individual stand- ing volume of different treatments were increased with CK; different treatments had significant difference on height and diamete, but had no significant difference on individual standing volume. HM8 strain was the best of all the rhizobium strains in perform of promoting growth. Effects of different treatments on organic matter and soil nutrition element of Acacia mangium young trees were showed P 〉 organic matter 〉 N 〉 K, general performance of 6 rhizobium strains was HM8 〉 ZG4 〉 HM4 〉 ZG3 〉 HJ7 〉 HJ6.
