Multifunctional seedling growth box used for corn breeding

Abstract

The invention discloses a multifunctional seedling growth box used for corn breeding. The multifunctional seedling growth box comprises a seedling growth box body and a transparent box cover, whereinthe upper end of the seedling growth box body is provided with a carbon dioxide generator and a controller; the carbon dioxide generator is communicated with the inner cavity of the seedling growth box body through an air delivery pipe; a bracket, a seedling growth plate, a temperature sensor, a moisture detector and a carbon dioxide sensor are arranged in the seedling growth box body; the bracketis provided with a chute; the bottom surface of the seedling growth plate is provided with a sliding block; the sliding block and the chute are in sliding cooperation connection; the upper surface ofthe seedling growth plate is provided with a seedling growth groove; the bottom of the seedling growth groove is provided with a water discharging pipe; the water discharging pipe is communicated with an exportation pipe in the seedling growth plate; a water conveying pipe and a floodlight are arranged above the seedling growth plate in the seedling growth box body; the water conveying pipe is provided with a trickle irrigation water dropper. Compared with the prior art, the multifunctional seedling growth box has the advantages of simple structure, low construction price, stable light intensity and controllable illumination time, carbon dioxide can be guaranteed to be sufficient, and the multifunctional seedling growth box is favorable for the growth of corn seedlings.

Description

technical field [0001] The invention belongs to the technical field of seedling raising devices, in particular to a multifunctional seedling raising box for corn breeding. Background technique [0002] The seedling box is one of the commonly used tools in modern agricultural production and agricultural research, and is usually used for the cultivation of seeds and seedlings of crops. Although the seedling box has the advantages of being easy to control the growth of seeds and seedlings, not damaging the root system when transplanting, and having a high survival rate, saving seed consumption, reducing production costs, and can ensure neat emergence and uniform growth of seedlings. But also there are some problems in existing seedling box, for example, adopt the seedling box of sunlight, because sunlight changes with time and season, sunlight intensity and length are all different, thereby influence emergence rate; Adopt the seedling box of lighting facility, Usually, a light...
