摘要: 为探究微生物菌剂与有机肥复配对植烟土壤微生物区系的影响,通过田间小区试验,采用双因素完全组合设计,测定不同处理下各生长期植烟土壤中细菌、放线菌和真菌的数量。结果表明,各复配处理中,土壤细菌数量在烤烟3个生长期分别以氨基酸有机肥、菌渣、虾肽有机肥与微生物菌剂复配处理最高,尤其是氨基酸有机肥与微生物菌剂复配处理,高出其他复配处理249.1%~705.5%;土壤放线菌数量在烤烟3个生长期分别以油枯、氨基酸有机肥、虾肽有机肥与微生物菌剂复配处理最优,尤其是旺长期,高出其他复配处理1.2%~116.6%;烤烟团棵期和成熟期的土壤真菌数量均以黄腐酸有机肥处理最低,旺长期以牛粪复配处理最低。综合来看,微生物菌剂与氨基酸有机肥复配能有效改善植烟土壤微生物区系组成,是微生物菌剂与有机肥复配的最佳组合方式。

Abstract: In order to study the effects of the combination of microbial agents and organic fertilizers on the microbial flora of tobacco planting soil, through field plot experiments and two factors and complete combination, the number of bacteria, actinomycetes and fungi in tobacco planting soil of different treatments at different periods were determined. The results showed that,in all combinations, the number of soil bacteria at the three periods of flue-cured tobacco was the highest under the combination of microbial agent and organic fertilizers of amino acid organic fertilizer, microbial residue and shrimp peptide organic fertilizer, respectively, especially amino acid organic fertilizer compounding treatment, which was 249.1%~705.5% higher than that of other compounding treatment; The number of soil actinomycetes was optimally under the combination of microbial agents oil dry, amino acid organic fertilizer and shrimp organic fertilizer, respectively, especially at vigorious growth period, which was 1.2%~116.6% higher than that of other treatments; The number of soil fungi at the sapling stage and mature period of flue-cured tobacco was the lowest with fulvic acid organic fertilizer, and was the lowest at vigorious growth with cow manure compound treatment. In summary, the combination of microbial agent and amino acid organic fertilizer can effectively improve the microbial flora of planting tobacco soil, which is the best combination of microbial agent and organic fertilizer.
