AI Technical Summary

Technical Problem

During the implementation of the existing slough technology, it is difficult to achieve the ideal disinfection effect of the maximum temperature and high temperature duration of deep soil during the implementation process, resulting in insufficient disinfection of deep soil.

Method used

The deep soil sanitation method is adopted based on intermittent sterilization. By setting up a hot air circulation pipe system in the later stage of the sanitation, the extremely hot air is transported into the ridge ditch by blowers, and the heat is increased and cooled intermittently to achieve high-temperature disinfection of the deep soil.

Benefits of technology

Effective disinfection and sterilization of deep soil is achieved, avoiding the recurrence of diseases after the shed is over, improving the soil structure, and suitable for the growth of deep root crops.

Abstract

The invention discloses a deep soil greenhouse closing method based on intermittent sterilization. The method comprises the following steps: (1) cleaning a greenhouse; (2) soil preparation; (3) irrigation; 4, ridging, wherein deep ridges are dug in the soil in the long edge direction of the greenhouse; (5) arranging a hot air circulation pipe system: arranging an air supply hole pipe in the direction perpendicular to the deep ridge, wherein the air supply hole pipe is connected with an air blower through a hot air pipe; (6) film covering; (7) closing the greenhouse, namely performing intermittent sterilization treatment on deep soil in the later period of closing the greenhouse, specifically, according to weather forecast, selecting a time period when continuous cloudy and sunny days exist and the highest temperature exceeds 35 DEG C, starting an air blower for 1 hour at 13-14 o'clock every day, and conveying extremely hot air at the upper part in the greenhouse into furrows; starting an air blower for 1 hour at 2-4 o'clock in the morning of the next day to cool the soil, and starting the air blower again for 1 hour at 13-14 o'clock in the noon of the current day to blow hot air into the furrows; repeating the operation until the last day of greenhouse closing, and not performing the blowing operation after noon blowing is completed on the last day of greenhouse closing; and (8) opening a shed.
