Abstract

Abstract:

To deeply explore the responses of strawberry continuous cropping soil to different disinfection methods, this study set up three treatment groups: T1 (disinfected with ozone water), T2 (disinfected with hypochlorous acid water), and T3 (high-temperature and high-pressure sterilization), with clear water treatment as the control, and studied the effects of different disinfection methods on soil physical and chemical properties, soil enzyme activities, and soil microbial biomass after 1 day, 15 days, and 30 days of treatment. The results showed that ozone water treatment, hypochlorous acid water treatment and high-temperature and high-pressure sterilization treatment all affected the physical and chemical properties of the soil and the activity of soil enzymes to varying degrees, and all increased the pH value of the soil. Among them, ozone water effectively increased the content of available potassium and available nitrogen in the soil. The soil nutrient content after hypochlorous acid water treatment did not change significantly. The activities of acid phosphatase(ACP), leucine aminopeptidase(LAP) and cellobiohydrolase(CBH) were at a relatively high level. The content of dissolved organic carbon(DOC) was higher than those in other treatments. In addition, high-temperature and high-pressure sterilization treatment reduced the content of available phosphorus and organic matter in the soil and the activities of β-glucosidase(βG) and ACP, but the contents of DOC and microbial biomass phosphorus(MBP) under this treatment were relatively high. In conclusion, all three disinfection methods selected in this experiment had certain improvement effects on the soil for strawberry continuous cropping. Compared with the traditional chemical disinfection methods, none of them had chemical residues and were environmentally friendly, exhibiting broad application prospects in modern agricultural production.
