| 摘 要： | 为了研究土壤微生物群落对肥料响应的一般趋势,采用整合分析方法综合了与无机和有机肥料添加对土壤微生物群落影响有关的观察结果(N:氮;P:磷;NP:氮和磷;PK:磷和钾:NPK:氮磷钾;OF:有机肥;OF+NPK:有机肥和氮磷钾)。PK、NPK、OF和OF+NPK的添加分别使总磷脂脂质脂肪酸(PLFA)增长了52.0%、19.5%、334.3%和58.3%。NP、OF和OF+NPK的添加分别使真菌增加了5.6%、21.0%和8.2%。NP,NPK和OF的添加分别使细菌增加6.4%、9.8%和13.3%。NP和NPK添加分别使放线菌增加7.0%和14.8%。硝酸铵添加减少了革兰氏阴性菌(G–)。氮添加增加了农田中总PLFA、细菌和放线菌,减少了森林中的细菌和真菌,以及草地中的F/B比值。氮磷钾添加增加了森林而不是农田中的总PLFA。氮的添加速率与氮的添加对革兰氏阳性细菌(G+)和G–的影响呈正相关。因此,不同肥料对土壤微生物群落的影响可能不同。有机肥料比无机肥料对土壤微生物群落具有更大的积极作用。肥料对土壤微生物群落的影响因生态系统类型而异。氮添加对土壤微生物群落的影响与氮添加形式和氮添加速率有关。

| Abstract: | In order to investigate the general tendency of soil microbial community responses to fertilizers, a meta-analysis approach was used to synthesise observations on the effects of inorganic and organic fertilizer addition (N: nitrogen; P: phosphorus; NP: nitrogen and phosphorus; PK: phosphorus and potassium; NPK: nitrogen, phosphorus and potassium; OF: organic fertilizer; OF+NPK: organic fertilizer plus NPK) on soil microbial communities. Among the various studies, PK, NPK, OF and OF+NPK addition increased total phospholipid fatty acid (PLFA) by 52.0%, 19.5%, 334.3% and 58.3%, respectively; while NP, OF and OF+NPK addition increased fungi by 5.6%, 21.0% and 8.2%, respectively. NP, NPK and OF addition increased bacteria by 6.4%, 9.8% and 13.3%, respectively; while NP and NPK addition increased actinomycetes by 7.0% and 14.8%, respectively. Addition of ammonium nitrate rather than urea decreased gram-negative bacteria (G -). N addition increased total PLFA、bacteria and actinomycetes in croplands, but decreased fungi and bacteria in forests, and the F/B ratio in grasslands. NPK addition increased total PLFA in forests but not in croplands. The N addition rate was positively correlated with the effects of N addition on gram-positive bacteria (G +) and G -. Therefore, different fertilizers appear to have different effects on the soil microbial community. Organic fertilizers can have a greater positive effect on the soil microbial community than inorganic fertilizers. The effects of fertilizers on the soil microbial community varied with ecosystem types. The effect of N addition on the soil microbial community was related to both the forms of nitrogen that were added and the nitrogen addition rate. |
