Effect of biological microbial fertilizer application on growth and devel-opment of eggplant and soil environment
In order to improve the quality and yield of facility eggplant,and seek for suitable fertilizer application scheme,Jinyuanqie No.5 was used as experimental material in this study.During planting,biological bacterial fertilizer was used to irrigate the roots,and biological bacterial fertilizer was sprayed during the period of flowering and fruiting,and the commonly used fertilizer application methods by farmers was used as control,the agronomic traits,soil nutrients,soil microorganisms,yield and quality of eggplant are investigated.The results showed that the plant height,width of seedling,stem diameter and leaf area after the application of biological bacterial fertilizer increased,reaching 121.24 cm,88.6 cm,30.6 mm,and 3.58 m2,respectively.Compared with the control group,the increase rate were 21.19％,35.89％,20.00％,and 61.99％,respectively.During the three measured periods,the pH of the soil treated with chemical fertilizers showed little change while the pH of biological bacterial fertilizers treatment decreased from 7.74 to 7.44,which was rela-tively neutral.The soil nutrients in both treatments were increasing,and the bacterial fertilizer treatment was higher than the chemical fertilizer treatment.The biological bacterial fertilizer treatment also significantly increased the total number of bacteria,actinomycetes,and bacteria/fungi ratio,reducing the number of fungi,alleviated the imbalance of soil microbi-ota.The biological bacterial fertilizer treatment also improved the yield and quality of eggplant,reduced.the cellulose con-tent and improved soluble sugar,vitamin C,soluble protein content.In general,the application of biological bacterial fer-tilizer can accumulate soil nutrients,and promote the formation of eggplant yield and quality.The research results provide suitable ertilizer application scheme for high quality and efficient cultivation of eggplant.
