Abstract

The invention belongs to a solar application device, and particularly relates to a soil treatment device. A light gathering and heat returning type soil disinfecting and repairing device comprises an induced draft fan (1), an air outlet flue (2), a groove type multi-hook-face solar condenser (3), a glass cover plate (4), a double-layer glass vacuum pipe (5), a ventilation heat absorbing body (6), an insulating layer (8), a hot air cavity (7), a first-level metal heat exchange plate (13), a feeding hopper (10), a mushroom-shaped ventilation channel (16), a tail air backflow channel (9), an exhaust pipe (11), a natural vibration spring (15), a second-level metal heat exchange plate (17), a soil sliding conveying belt (18), a feeding air channel (14) and a discharging port (20). Soil is heated through high-temperature air heated through solar energy, then disinfecting and killing of injurious insects, pathogenic bacteria and weed seeds in the soil and separation of volatile organic compounds in the soil are carried out, the fossil energy does not need to be consumed, pollution to the soil is avoided, and food safety is effectively guaranteed.

Description

technical field

[0001] The invention belongs to a solar energy application device, in particular to a soil treatment device. Background technique

[0002] my country's facility agriculture has developed rapidly in recent years, especially in the northern high latitudes. According to statistics, the planting output of facility agriculture is 3 to 4 times, or even more than ten times, that of open field planting. Therefore, facility agriculture has become an important agricultural technology project to effectively solve the contradiction between more people and less land in our country.

[0003] Although facility agriculture can control and adjust the growth environment of crops, the interior of facility agriculture is a closed space with high temperature and high humidity, especially the slow air flow, which makes the crops grown in facility agriculture vulnerable to pests, pathogenic bacteria, etc. violations are very difficult to deal with. Pests and pathogenic bacteria ...
