Mist culture barrel thermal insulation layer and design method thereof

Abstract

The invention discloses a mist culture barrel thermal insulation layer and a design method thereof and aims at solving the problem that the temperature environment of a plant root system is poor in buffering in an existing small mist culture barrel. The mist culture barrel thermal insulation layer is composed of a thermal insulation layer outer barrel, a thermal insulation layer filler and a thermal insulation layer inner barrel, wherein both the thermal insulation layer outer barrel and the thermal insulation layer inner barrel are respectively an opened cylindrical structural component with a bottom, and the thermal insulation layer filler is a ring-body structural component; the thermal insulation layer outer barrel, the thermal insulation layer filler and the thermal insulation layer inner barrel are sequentially sleeved together for fixed connection, particularly, the thermal insulation layer inner barrel is put in the thermal insulation layer outer barrel, the rotation axes of the thermal insulation layer inner barrel and the thermal insulation layer outer barrel are collinear, the inner side surface of the barrel bottom of the thermal insulation layer outer barrel is in contacted connection with the bottom surface of the barrel bottom of the thermal insulation layer inner barrel, namely the thermal insulation layer filler does not exist, the thermal insulation layer filler is positioned between the thermal insulation layer inner barrel and the thermal insulation layer outer barrel, and the top end surfaces of the thermal insulation layer outer barrel, the thermal insulation layer filler and the thermal insulation layer inner barrel are coplanar. The invention further provides the design method of the mist culture barrel thermal insulation layer.

Description

technical field [0001] The invention relates to an aeroponic device for cultivating vegetable crops, which belongs to the technical field of plant cultivation. More precisely, the invention relates to an aeroponic bucket heat insulation layer and a design method thereof. Background technique [0002] Aerosol cultivation (abbreviated as aeroculture) is a new type of soilless cultivation mode that allows the roots of plants to leave the substrate and water and place them in a dark, relatively closed aerosol environment for growth and development. It meets the needs of plant roots for water and minerals through the atomized nutrient solution, so that the roots have sufficient oxygen and free space to expand, and can grow without resistance. Compared with other soilless cultivation methods, The aerosol cultivation technology has the characteristics of saving water and fertilizer, adjusting the water-air balance of the root system, etc., and is widely used in modern agricultural ...
