Effects of semi-coke fertilizer application on olive growth and soil microbial community
Three olive seedlings are selected as test materials to explore the effects of semi-coke fertilizer on olive growth and soil microbial community diversity.The results show that the application of semi-coke fertilizer can increase the growth of the rhizome and plant height of the three olive varieties to a certain extent,and the promotion effect is the best under the medium amount treatment;The effect of fertilization amount on soil microorganisms of the three olive varieties is the same.Compared with the treatment without fertilization,fertilization decreases the total number,abundance and diversity of ASV/OTU at each taxonomic level of fungi.But the total number,abundance and diversity of ASV/OTU at each taxonomic level of bacteria increases with the increase of fertilization amount;The higher relative abundance of fungi in the soil of the three olive varieties are ascomycetes,basidiomycetes and mucormycotes,and the relative abundance of ascomycetes is higher than that of basidiomycetes;The higher relative abundance of soil bacteria are actinomycetes,proteus and acidobacteria.In general,the application amount of semi-coke fertilizer with medium treatment is conducive to promoting the growth of olive stem and plant height,while the application amount of semi-coke fertilizer with high treatment is conducive to increasing the number of soil microorganisms,improving the microbial community structure and the soil fertility.
