| 摘 要： | 对柳杉１年生苗施用矿质肥料，分析苗木根区与非根区土壤养分、土壤酶活性、土壤微生物数量。结果表明：施肥显著地增加了柳杉苗根区土壤的微生物数量，细菌增幅最大，其次是真菌，施肥对非根区土的微生物数量无明显影响；施肥对柳杉苗根区土壤酶活性影响较复杂，脲酶和蔗糖酶的活性不受施肥影响，磷钾和氮磷钾处理均能显著提高蛋白酶活性，施肥还能有效地降低柳杉苗根区土壤多酚氧化酶的活性。

| Abstract: | The results indicated that applying mineral fertilizers evidently increased the soil microbial number at the root zones of Cryptomeria fortunei seedlings,the bacteria number increased was the most and then fungi;PK and NPK treatments could both obviously raise the protease activity;and applying fertilizers could also effectively reduce the soi ployphenol oxidase activity at the root zones of.C.fortunei seedlings. |
