菌肥配施氨基酸水溶肥对烤烟根际土壤微生态环境及生长的影响
Effects of Bacterial Fertilizer Combined with Amino Acid Water-soluble Fertilizer on Rhizosphere Soil Micro-ecological Environment and Growth of Tobacco Plants
摘要
Abstract
To investigate the effects of bacterial fertilizer and amino water-soluble fertilizer combined application on rhizosphere soil and growth of tobacco plants under the condition of chemical fertilizer control,a field experiment was conducted to study the effects of bacterial fertilizer combined with amino water-soluble fertilizer on tobacco plant growth,rhizosphere soil physical and chemical properties,enzyme activity,bacterial community structure and diversity under the condition of 10%nitrogen reduction,with conventional fertilization as control(A0B1).The results showed that compared with A0B1,under the condition of 10%nitrogen reduction,bacterial fertilizer combined with amino water-soluble fertilizer showed various effects.(1)The contents of organic matter,alkali-hydrolyzable nitrogen and available P and the activity of catalase and urease in rhizosphere soil increased,and the activity of nitrate reductase decreased.(2)The diversity and relative abundance of bacteria and fungi in rhizosphere soil were increased,the relative abundance of specific bacteria,fungi and dominant bacteria(Chloroflexi,Acidobacteria and Gemmatimonadetes)increased,and the relative abundance of dominant bacteria(Actinobacteria and Entorrhizomycota)decreased.(3)Redundancy analysis showed that soil pH was the key environmental factor positively correlated with the abundance of bacterial and fungal communities,and available P was negatively which correlated with the relative abundance of bacterial communities.(4)This combined application method promoted the growth and development of tobacco and leaf opening.In general,under the condition of 10%nitrogen reduction,the application of bacterial fertilizer combined with amino soluble fertilizer can improve the rhizosphere soil nutrient level,improve the rhizosphere micro-ecological environment,and promote the growth and development of tobacco plants,the overall effect of bacterial fertilizer+75.0 g/hm2 amino water-soluble fertilizer treatment(A1B3)is better.关键词
