Abstract:
Three varieties muskmelon were used as experimental materials,and fertilization treatments,included 180 kg·hm-2 chemical fertilizer (T1) and 270 L·hm-2 microbial fermentation solution (T2),were chosen in greenhouse with fertile soil to study effects on rhizosphere soil nutrient content,microflora,and quality and yield,in order to provide reference for reducing the amount of chemical fertilizer in fruits and vegetables.The results showed that there was no significant difference in nutrient content of rhizosphere soil between T1 and T2,when application in N,K was reduced by 73.7%,97.8% and P increased by 31.4% in T2 compared with T1.The diversity of T2 bacterial flora was greater than that of T1 without no significant difference,but the diversity of T1 fungal flora was significantly higher than that of T2.At the genus level,T2 had 46 bacterial flora greater in relative content than T1,and the latter had 185 fungal flora greater than the former.Furthermore,yield and soluble solids content did not reach significant differences between treatments.In conclusion,reduction of nitrogen and potassium application can be achieved by replacing chemical fertilizers with microbial fermentation solution in high fertility soil in greenhouse.
