【摘要】：以赣无油茶无性系(Camellia oleifera Abel)为材料,分别设施用油茶专用肥(ZYF)、生物有机肥(YJF)、复合肥(FHF)和不施肥(CK)4个处理,研究不同肥料处理下油茶林土壤微生物及土壤酶活性的季节变化。结果表明:施用不同肥料对土壤细菌数量有明显的促进作用,效果最好的是ZYF;ZYF、YJF施肥处理对于提高油茶林土壤中放线菌数量效果较好;有机肥对提高土壤微生物量碳、土壤微生物量氮含量效果最好;YJF施肥处理对提高脲酶活性效果最佳,其次是ZYF;脲酶活性基本趋势为夏季含量最高,秋季含量最低;YJF施肥处理对于提高土壤酶整体效果最好。综合分析可知,油茶林土壤微生物学特性之间具有密切的相关关系,在一定程度上能表征土壤健康状况,可作为评价土壤肥力的生物指标。
[Abstract]:Using (Camellia oleifera Abel) as material, the special fertilizer of Camellia oleifera, (ZYF), biological organic fertilizer, (YJF), compound fertilizer (FHF), and no fertilizer (CK), were treated respectively. The seasonal changes of soil microorganism and soil enzyme activity under different fertilizer treatments were studied. The results showed that the application of different fertilizers could obviously promote the number of soil bacteria, and the best effect was that the treatment of ZYF;ZYF,YJF fertilization could increase the number of actinomycetes in the soil of oil tea plantation. Organic fertilizer had the best effect on increasing soil microbial biomass carbon and soil microbial biomass nitrogen content, YJF fertilization had the best effect on increasing urease activity, followed by ZYF; urease activity basic trend was the highest in summer and the lowest in autumn. The effect of YJF fertilization on soil enzyme was the best. Comprehensive analysis shows that there is a close correlation between soil microbiological characteristics in oil tea forest, which can be used as a biological index to evaluate soil fertility.
