Carbon crystal electric-heated bed and application of carbon crystal electric-heated bed in fruit and vegetable seedling culturing of facility

Abstract

The invention discloses a carbon crystal electric-heated bed and an application of the carbon crystal electric-heated bed in fruit and vegetable seedling culturing of a facility. The carbon crystal electric-heated bed comprises a carbon crystal electric-heated plate, a ground temperature sensor and a temperature controller, wherein the carbon crystal electric-heated plate is internally provided with a conductive metal sheet; the conductive metal sheet is connected with two leads; the other ends of the two leads are connected with the temperature controller; and the temperature controller is also connected with the ground temperature sensor. The carbon crystal electric-heated bed can be applied to the production of the fruit and vegetable seedling culturing of the facility by means of being placed on a seedling culturing frame or on the ground; the temperature of the vegetable growing environment as well as the survival rate and the sound seedling index of young fruit and vegetable seedlings of the facility can be increased; the carbon crystal electric-heated bed serving as a novel heating facility for the production of the fruits and the vegetables of the facility has the advantages of high efficiency, energy saving, simplicity, environment friendliness and the like; and the carbon crystal electric-heated bed is capable of effectively relieving the adverse effects of severe weather such as cold air outbreak on the vegetable seedling culturing of the facility and has significant popularization and application values.

Description

technical field [0001] The invention relates to a carbon crystal electric heating hotbed and its application in facility fruit and vegetable seedling cultivation. Background technique [0002] Seedling cultivation is an important link in winter and spring facility vegetable production in northern my country. Cold waves frequently occur in winter and spring in my country, and the low temperature seriously reduces the growth rate, number of flower bud differentiation and robustness of seedlings of facility vegetables, especially temperature-loving fruits and vegetables (such as tomatoes, cucumbers, etc.), thus affecting the yield and quality of vegetable products during the harvest period. quality. Therefore, using a reasonable heating method to cultivate robust seedlings has become a key technology to ensure the annual production of facility vegetables and maintain high vegetable production efficiency. The solar greenhouse is the main facility for raising vegetable seedlings...

AI Technical Summary

Problems solved by technology

However, the traditional heating facilities have the following disadvantages: ①The installation and use costs are high, occupying the space resources of the greenhouse, and reducing the utilization rate of the greenhouse land; Cross-flow heat release accounts for 50% to 60% of the total heat dissipation in the greenhouse (Xu Gangyi, Liu Mingchi, Li Wu, et al. Electric boiler heating solar greenhouse soil heating system. China Agricultural Science Bulletin [J], 2011, 27(14): 171- 174); ③ serious environmental pollution, coal and fuel oil cause air pollution; ④ requires professional management personnel to control, low degree of automation, occupying human resources; ⑤ uneven heat generation and short service life of heating cables
