| 摘 要： | 为研究控释尿素与常规尿素配施条件下对玉米根际土壤微生物的影响,采用不同肥料配比处理,对玉米根际土壤细菌、真菌、放线菌采用平板计数法进行数量测定;对玉米成熟期根际土壤微生物数量变化、土壤氮素含量变化及玉米产量相关因素进行研究,结果表明控释尿素与常规尿素不同配施条件下,与CK相比施用肥料的各个处理,土壤微生物数量均增加,CRU100%处理有利于增加土壤细菌、土壤氮素含量及玉米产量,CRU40%+PU60%处理在增加土壤真菌及放线菌数量上优于其他配比。针对实际生产应用及对土壤微生物整体影响,综合比较本研究表明CRU40%+PU60%处理为最佳配比并为控释尿素与常规尿素配施条件下土壤微生物生态环境的深入研究提供依据。

| Abstract: | The objective of current study was to investigate the effects of controlled-release urea combined with conventional urea on rhizosphere soil microorganisms of maize.The numbers of bacteria,fungi,actinomycetes of rhizosphere soil were determined through colony counting method.The research included the effects of different fertilizers treatments on the changes of rhizosphere soil microorganisms of maize,nitrogen content of soil,yield and yield components of maize at maturity.The results showed that effects of controlled-release urea combined with conventional urea on the number of microorganisms of soil were different.Compared with CK treatment,the amounts of microorganisms in fertilizer treatments were higher.The CRU100% treatment improved of nitrogen content of soil and yield of maize.CRU40%+PU60% had higher value on the number of fungi and actinomycetes.According to the practical production and application and the overall effects on the soil microorganisms,the research of comprehensive comparison showed that CRU40%+PU60% was the optimum proportion,and the study provided evidence for further research on ecological environment of soil microorganism under controlled-release urea combined with conventional urea. |
