| 摘 要： | 为探讨干旱半干旱地区砂田土壤微生物特征,对不同砂龄砂田交界层土壤微生物区系及其影响因素进行试验研究.结果表明:在交界层土壤中的微生物区系以细菌为主,放线菌次之,真菌最少;砂田交界层土壤微生物数量与砂田砂龄有关,砂龄为13 a的土壤细菌数量达最高,砂龄为26 a砂田,土壤真菌数量达最高,放线菌的数量和比例都达到最大;随着...

| Abstract: | To study the soil microbial characters in gravel and sand mulched field(GSMF) in arid and semiarid area,the soil micro flora and the influence factors of GSMF and its boundary layer in different age of GSMF had been studied through experimentation.The results showed that the quantity of micro flora in boundary layer was bacteria>actinomycete>fungi.It is related on soil microbial number and the age of GSMF,that is the number of bacteria reached the highest number when the age of GSMF was 13 a.When the age of... |
