摘　　要：为了解缓释纳米肥料的肥效及其对生态环境的影响,设置青椒栽培盆栽实验,研究施用缓释纳米肥料对青椒生长、土壤养分、酶活性及微生物的影响。结果表明:(1)施用缓释纳米肥料,能促进青椒生长,但由于肥效缓,对青椒的生长促进不及化肥。(2)施加缓释纳米肥料显著提高土壤养分,尤以碱解氮为最,增幅达到100%。(3)施用缓释纳米肥料能显著提高土壤酶活性和土壤微生物数量,与空白相比,处理2的土壤脱氢酶和过氧化氢酶活性分别增加37.4%和21.3%,土壤细菌、放线菌和真菌分别增加了50%、72%和208%。因此,施用缓释纳米肥料可提高农田土壤养分、土壤酶活性和微生物数量,减少养分流失,改善农田土壤生态环境,具有良好的推广应用价值。In order to examine the fertilizer effect of slow-release Nano-fertilizer and its impact on the ecological environment,a cultivation pot experiment was arranged to study the influences of application of slow-release Nano-fertilizer on green pepper growth,soil Nutrients,enzyme activity and microorganisms. The results were as follows：（1）The application of slow-release Nano-fertilizer can promote the growth of green pepper,but due to the slow effect of fertilizer,the growth of green pepper was not as good as that of chemical fertilizer.（2）Application of slow-release Nano-fertilizer significantly increased soil nutrients,especially alkaline nitrogen,with an increase of 100%.（3）Application of slow-release Nano-fertilizer significantly increased soil enzyme activity and soil microbial population.Compared with blank,soil dehydrogenase and catalase activities of treatment 2 increased by 37.4% and 21.3%,respectively,and soil bacteria,actinomycetes and fungi increased by 50%,72% and 208%,respectively. Application of slow-release Nano-fertilizer can improved soil nutrient,soil enzyme activity and soil microorganism,reduce nutrient loss and improve soil ecological environment,with a good application value.
