Abstract

The invention discloses a ventilation method and a ventilation device for culturing seedlings of plants in full-closed environment, and relates to the technical field of agricultural growing. The ventilation method comprises that: in a full-closed seedling culturing box, an upper seedling culturing chamber, a suction fan, a lower seedling culturing chamber and an exhaust fan are communicated in turn through air ducts on two sides to form an internal circulating ventilation circuit; and the suction fan drafts air and the exhaust fan exhausts air so as to form internal circulating ventilation; and the ventilation device comprises a full-enclosed seedling culturing box 32, an upper seedling culturing chamber 3, a lower seedling culturing chamber 7, a suction fan 1, an exhaust fan 2, an air conditioner 4, a CO2 supplementing tank 5, an O2 supplementing tank 6, an automatic control device 8 and the like, has the function of simulating natural ventilation in the full-closed environment seedling culturing equipment, realizes the functions of uniform ventilation, dehumidification, humidification, heating, refrigeration, supplementation of O2 and Co2 and the like of multi-layer seedling culturing frame high-density seedling culture in the full-closed environment, is suitable for culturing the seedlings of the plants in greenhouses and plastic tents in various environments, and is also suitable for growing plants in the full-closed environment.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a ventilation method and a ventilation device for growing plant seedlings in a fully enclosed environment in the facility agriculture technology. Background technique [0002] In the prior art, there are two main ventilation methods for growing seedlings in greenhouses (including plastic greenhouses, glass greenhouses, etc.) in facility agriculture. One is to adopt the method of only installing two-way fans, blowing fresh air into the room or blowing the indoor The air is drawn out and discharged to the outside to achieve indoor ventilation and fresh air supplementation; another way is to open the covers on both sides of the greenhouse to allow natural ventilation. These ventilation methods all have the following deficiencies: one is that the indoor ventilation is uneven; the other is that the energy consumption of fan ventilation is large; Uniform ventilation, deh...
