Problems solved by technology

However, the price of red light chips is more than 2-3 times that of blue light chips. At the same time, the double-chip packaging mode itself increases the difficulty of the process and indirectly increases the production cost, thus restricting the application of LED plant lighting devices in the chip-plus-chip mode. to promote

Abstract

The invention relates to a method for seedling and planting dendrobii officmalis caulis by adopting an LED light source. LED plant growth light sources are obtained by utilizing the combination of red fluorescent powder stimulated by rare earth and a blue light chip and are applied to the growth of dendrobii officmalis caulis. The matrix of the fluorescent powder is one of aluminate matrix, vanadate matrix or nitride matrix, an emission spectrum ranges from the wavelength being 600nm to the wavelength being 660nm, an excitation spectrum ranges from the wavelength being 440nm-470nm, and the mass ratio of the fluorescent powder to organic silica gel is 1 to (4-20). The ratio of the integral area of the blue peak to the integral area of the red peak in the chip in the spectrum is 1 to (5-10). The fluorescent powder excited LED plant growth light sources can be applied to dendrobii officmalis caulis so as to promote the growth of dendrobii officmalis caulis, furthermore, the leaves are green, the newly born roots are dense, the root-stem parts are obviously sturdy, the stem height can achieve 15-28cm, the outer diameter of the stems can achieve 1-2cm, the illumination intensity can be effectively improved to conform to the sunny exposing property of dendrobii officmalis caulis, and the yield of effective ingredients, namely dendrobii officmalis caulis polysaccharide and dendrobine, can be increased, so that the method can be promoted in large scale.

Description

technical field [0001] The invention belongs to the cross technical field of LED light sources and dendrobium candidum seedling cultivation, and in particular relates to a method for growing and planting dendrobium candidum seedlings by using LED light sources. Background technique [0002] Dendrobium officinale is an important representative plant of orchidaceae epiphytes. It has been listed as the first of the "Nine Great Immortal Grasses of China" since ancient times. Anti-tumor and other pharmacological effects are called "Pharmaceutical Giant Panda" by the international medicinal plant community. And because the growth cycle of Dendrobium officinale is slow and the growth environment is harsh, it has extremely high scientific research value and economic value. Among the conditions required for its growth, "light" is the most difficult environmental factor to control, and it is also the main source of energy, which plays a key role in the photosynthesis of plants, growt...
