Embodiment 1

[0045] Under the condition of low temperature in winter (outdoor temperature is lower than 10°C), the substrate for planting a crop of watermelons should be disinfected.

[0046] (1) Set the automatic program: set the target temperature of the heat transfer oil to 120°C, the target temperature inside the tank to 75°C, and the switching time between modes for the driving direction of the drive motor 19 to be 20 seconds. The system automatically starts the electric heater switch circuit 20. Since the temperature inside the horizontal tank is low, three sets of electric heaters 6 are started at the same time. At this time, the maximum power is 100kw. After about 15 minutes, the temperature of the heat transfer oil reaches or approaches the target temperature in the tank. , the warm-up ends. Turn off both sets of heating elements.

[0047] (2) Feeding: Use the crawler conveyor mechanism 12 to put 2.5 cubic meters of watermelon-planted substrate into the horizontal tank 1, and the...

Embodiment 2

[0053] Under the condition of low temperature in winter (outdoor temperature below 10°C), disinfect tomato stalks

[0054] The technical solution of embodiment 2 is basically the same as that of embodiment 1, the only difference is that the feed amount of tomato stalks can reach 3 cubic meters, and the disinfection time in the horizontal tank 1 can be shortened to 1 hour.

[0055] The experimental results shown in Fig. Image 6 ,: The number of cultivable fungi (Red Bengal medium) in tomato stalks before feeding (A in the figure) was 9.06×10 3 CFU / g, the number of cultivable fungi after disinfection (B in the figure) was not found in Bengal red medium.

Abstract

The invention relates to a substrate fast sterilization and disinfection device and an application thereof. The device comprises a horizontal tank body, a control mechanism and a feed port, a vent cap and a discharge port formed in the horizontal tank body, wherein a spiral belt type stirring device and an oil heating device are also arranged in the horizontal tank body; the spiral belt type stirring device comprises a center shaft, a spiral belt, a group of scrapers and a drive motor; the oil heating device comprises an interlayer coating the horizontal tank body; an oil inlet is formed at the upper part of the interlayer, and an oil outlet is formed at the bottom; the interlayer is filled with heat conducting oil; at least one group of electric heaters is arranged in the heat conducting oil at the lower part of the interlayer; and the control mechanism comprises a drive motor forward / backward switching circuit controlled by a program control module, an electric heater switching circuit, an in-tank temperature sensing and heat conducting oil temperature sensor and working condition indicator lights for the drive motor switching circuit, temperature sensor and electric heater switching circuit. According to the invention, fast sterilization and disinfection can be performed on continuous cropping substrate or crop straw carrying continuous cropping obstacle pathogenic bacteria.

Description

technical field [0001] The invention relates to the technical field of facility agriculture cultivation substrate and crop straw disinfection, in particular to a substrate rapid disinfection device and its application. Background technique [0002] The drawbacks of facility agriculture under high-intensity utilization are becoming increasingly prominent in terms of soil health, ecological environment pollution and food safety, especially soil continuous cropping obstacles and secondary salinization are particularly important. The use of soilless substrate cultivation can well solve the problem of soil barriers in intensive facility planting. In addition, the production of cultivation substrate can absorb a large amount of agricultural waste, such as crop straw, cassava residue, mushroom residue, livestock and poultry manure, etc., which can achieve the purpose of resource utilization of waste. Based on these dual advantages, the development and application of cultivation su...
