摘要：采用PCR-DGGE技术对马鹿花5种种植模式土壤微生物多样性进行分析,结果表明:(1)5种种植模式土壤微生物垂直方向呈现随土层深度的增加其Simpson指数逐渐降低的趋势,且马鹿花-墨西哥柏林、马鹿花-蓝桉林Simpson指数高于其对照,马鹿花-三年桐林、马鹿花纯林Simpson指数低于其对照;(2)水平方向上马鹿花-蓝桉林总体丰富度、多样性指数及均匀度指数均最高,马鹿花-墨西哥柏林丰富度最低,马鹿花-三年桐林多样性及均匀度指数最低,相同条件下马鹿花纯林模式比马鹿花-三年桐林更优,中厚的棕壤较深厚的棕褐壤更适宜种植马鹿花。
By the PCR-DGGE technique, the soil microbial diversities und five planting modes of Pueraria wollichii DC., The results showed that： （1）With the increase of soil layer depth, the Simpson index of the soil microbial diversity under different planting modes decreased gradually in the vertical direction, and the Simpson index of P. wa!lichii DC.- Cupressus lusitanica forest and P. wallichii DC.-Eucalyptus globulus forest were higher than those under their contrast ,the Simpson index of P. wallichii DC.-Aleuvites fordii Hemsl forest and P. wallichii DC. forest were lower than those under their contrast; （2）In the horizontal direction, the richness, evenness, diversity index of the soil microbial diversity was different among the different planting patterns, mainly as follows： the richness, diversity index and evenness of P. wallichii DC.-E. globulus forest were all the highest, the richness of P. wollichii DC.-C. lusitanica forest and the diversity index, evenness of P. wallichii DC.-A. fordii Hemsl were both the lowest. Under the same conditions, the mode of P. wallichii DC. forest was better than the mode of P. wollichii DC.-A. fordii Hemsl forest. The medium thick brown soil was more suitable for planting P. wallichii DC. than the deep clark-brown soil.
