【摘要】：采用田间试验,研究了不施肥、施用生物有机肥、传统有机肥和化肥对猕猴桃土壤酶活性、微生物群落结构及其代谢的影响.结果表明:施用生物有机肥在猕猴桃生育期内可显著提高土壤蔗糖酶和荧光素二乙酸酯水解酶活性,分别比对照高出12.2%~129.4%、18.8%~87.4%.施用生物有机肥在膨大期和成熟期的土壤脲酶和酸性磷酸酶活性显著高于其他处理.Biolog微平板法测定结果表明,生物有机肥在猕猴桃生育期内提高了土壤微生物的平均每孔颜色变化率,增加了物种多样性、丰富度和均匀度,改变了微生物对6大类碳源的相对利用率,降低了微生物对氨基酸类碳源的相对利用能力,提高了微生物对多酚类和多胺类碳源的相对利用能力;主成分分析表明,对土壤中微生物起分异作用的碳源种类主要是糖类、氨基酸类和羧酸类.
[Abstract]:Field experiments were conducted to study the effects of non fertilization, bio organic manure, traditional organic manure and chemical fertilizer on soil enzyme activity, microbial community structure and metabolism of Actinidia. The results showed that bioorganic fertilizer could significantly increase the activity of invertase and fluorescein two acetate hydrolase in the growth period of kiwi fruit, respectively. The activity of soil urease and acid phosphatase in the swelling and mature period of 12.2%~129.4% was higher than that of other treatments. The results showed that the bioorganic fertilizer increased the average change rate of soil microorganism in the soil microorganism and increased the species diversity in the growth period of kiwi fruit. Richness and uniformity change the relative utilization of microbes to 6 major carbon sources, reduce the relative utilization ability of microbes to the carbon source of amino acids, improve the relative utilization ability of microbes to polyphenols and polyamine carbon sources, and the principal component analysis shows that the main types of carbon source of the microorganism in soil are carbohydrates and amino groups. Acids and carboxylic acids.
