Intelligent method for filling light by using photovoltaic LED lamps in seedling cultivation of vegetables

Abstract

The invention discloses an intelligent method for filling light by using photovoltaic LED lamps in seedling cultivation of vegetables. The method comprises the following steps of: preparing a seedlingcultivating shelf, covering seedlings with greenhouse film, installing the LED lamps, selecting solar photovoltaic panels, placing the solar photovoltaic panels, controlling the light-filling time, preparing seedling cultivating discs and seelding a cultivating matrix, and performing sprouting, sowing and management in a seedling period. According to the intelligent method for filling the light by using the photovoltaic LED lamps in seedling cultivation of the vegetables, the seedlings can be prevented from vein growth, the material content of seedling plants can be increased, and cultivationof strong seedlings can be promoted; besides, the occurrence of pests and diseases is reduced, the application of pesticides is reduced, and the quality of the vegetables is improved, so that the production effectiveness is further improved.

Description

technical field [0001] The invention belongs to the technical field of vegetable breeding, and in particular relates to a photovoltaic LED intelligent supplementary light method for vegetable seedling cultivation. Background technique [0002] Seedling cultivation is a key link in vegetable production, and cultivating strong seedlings plays a decisive role in the successful cultivation of vegetables. Under low temperature and low light conditions such as early spring, autumn and winter, common seedlings are weak and diseased, and grow slowly, which restricts the efficient cultivation and off-season production of vegetables. Insufficient light has become the biggest technical problem in vegetable seedling cultivation. Therefore, artificial supplementary light is used in production to improve the phenomenon of weak seedlings such as excessive growth of plants caused by insufficient light in the cultivation environment, thereby promoting the growth of vegetable seedlings. At p...

Problems solved by technology

[0003] At present, there are the following technical defects in supplementary lighting for vegetable seedlings: first, a fixed power supply is required, and the seedling cultivation location is limited, and most vegetable bases do not have power access, so supplementary lighting cannot be performed; second, an external power supply is required, which wastes electric energy, especially The use of fluorescent lamps, especially metal halide lamps, and incandescent lamps consumes more power when supplementing light; third, the supplementary light period is relatively random, and has not been verified by experiments, and the supplementary light effect is average; fourth, the distribution of light sources is unscientific when supplementing light, and the light quality and The light intensity is yet to be regulated

LED has the advantages of small size, light weight, long life, special wavelength, low driving voltage, high light efficiency, low energy consumption, safety, reliability and durability, and is not easy to fade, but there is no systematic use of photovoltaic power generation in vegetable seedling cultivation. Driving LED supplementary light technology, the conventional way of driving through a fixed AC power source limits its popularization and application
