Plant characteristic spectrum experimental box and experimental method thereof

Abstract

The invention relates to a plant characteristic spectrum experimental box and an experimental method thereof. A plurality of monocolor LED (Light-Emitting Diode) light sources, a multi-layer culturing chamber, a temperature regulating device, a humidity regulating device, an intelligent control device and the like are arranged in the plant characteristic spectrum experimental box, the plant characteristic spectrum experimental method comprises the steps of irradiating leaves of the plant respectively by adopting different wavelengths of monocolor light, measuring corresponding light intensity by adopting a spectrum radiometer, testing the photosynthesis rate of leaves by adopting a photosynthesis tester to obtain the relationship of the light intensity corresponding to corresponding wavelength and the plant photosynthesis rate, thus obtaining the characteristic spectrum of the specific plant; and carrying out cultivation experiments by taking the obtained plant characteristic spectrum as a lighting source for the plant, thus obtaining the relationship of lighting time and photosynthesis of the light source and the yield. The plant characteristic spectrum experimental box and the experimental method thereof provide experimental technology and means for researching plant physiology, and lay the foundation of manufacturing of characteristic spectrum light source suitable for plant growth, thus being capable of meeting the demand on the scientific and research and production of modern agriculture.

Description

technical field [0001] The invention relates to a plant characteristic spectrum experiment box and an experiment method thereof. Background technique [0002] The growth of all things depends on the sun, which illustrates the importance of light to the growth of plants. Plants are divided into sun-loving plants, neutral plants and shade-loving plants. Various plants have different needs for sunlight. For each plant, it has its most suitable spectrum and light intensity for photosynthesis, that is, its characteristic spectrum. With the advancement of science and technology, artificial light sources continue to develop. Among them, LED light sources are not only energy-saving and environmentally friendly, but also have a long life and rich spectrum. They can emit specific spectra and are easy to control. In the selection of plant lighting sources, LED lights are favored by researchers at home and abroad. Countries have increased the research and development of LED lighting i...
