| 摘 要： | 试验研究培肥方式对松嫩平原黑土生态系统中与N素转化有关的土壤微生物(好气性自生固氮菌、氨化细菌、亚硝酸盐细菌和反硝化细菌)数量的影响,结果表明:单独施入农肥可提高土壤好气性自生固氮菌、氨化细菌及反硝化细菌数量;化肥单独施用可降低土壤好气性自生固氮菌数量,提高反硝化细菌数量;农肥化肥等量配比施入土壤好气性自生固氮菌、亚硝酸盐细菌及反硝化细菌数量均增加。

| Abstract: | Field experiment was conducted to research the effect of manure and chemical fertilizer on the number of nitrogen transferrer edaphon(e.g.aerobic nitrogen-fixing bacteria,ammonifiers,nitrite bacteria and denitrifying bacteria)in black soil ecosystems.Results show that application of manure increase the number of aerobic nitrogen-fixing bacteria,ammonifiers and denitrifying bacteria,while chemical fertilizers reduce the number of aerobic nitrogen-fixing bacteria in black soils,increase the number of denitrifying bacteria.Otherwise combination of equally proportioned manure and chemical fertilizer promotes aerobic nitrogenfixing bacteria,nitrite bacteria and denitrifying bacteria activities. |
