Method for cultivating brassica chinensis to bloom indoors with LED light source

Abstract

The invention discloses a method for cultivating brassica chinensis to bloom indoors with an LED light source and belongs to the field of biotechnology. The method comprises the following steps: after germination for 2-3 days, seeds of the brassica chinensis sprout white buds and then are sown in a nutrition pot which is 25 cm in height and 12 cm in width, wherein vermiculite and grass carbon as the substrate at the ratio of 1V:1V are loaded in the nutrition pot; and after 7-8 days, seed leaves are flattened, and the brassica chinensis seedlings are cultivated under a light-emitting diode (LED) with monochrome red light and blue-red combination light at the ratio of 2:7 for 90 days, and a light source with monochrome red light and blue-red combination light at the ratio of 2:7 is most suitable for brassica chinensis to bloom. The method has the advantages of simplicity of operation, short blooming time and excellent fertility of plants, energy conservation and environmental protection, and the like, and is applied to the field of indoor quick breeding, industrialized production of breeds and the like.

Description

technical field [0001] The invention relates to a method for cultivating flowering green vegetables indoors by using an LED light source, and belongs to the field of biotechnology. Background technique [0002] Green vegetables are one of the most important green leafy vegetables cultivated and eaten in southern my country. However, the current situation of small green cabbage breeding is not optimistic. The breeding methods are backward, the potential for increasing yield is low, the resistance and quality are not ideal, and the germplasm degrades rapidly. The use of LED light sources in an environment-controllable room for flowering and cultivation of green cabbage can break the seasonal restrictions on the breeding of small green cabbage, and enable the small green cabbage to bloom at any time of the year, which is beneficial to the hybrid breeding and reproductive research of small green cabbage. [0003] Light is sensitive to light quality, light intensity, photodirect...

Problems solved by technology

The artificial light sources used in agriculture and biology for a long time mainly include fluorescent lamps, incandescent lamps, sodium lamps, and dysprosium lamps. Among them, high-pressure sodium lamps and dysprosium lamps are light sources with high luminous efficiency and effective photosynthetic efficiency, but they consume a lot of power and emit spectrum. It cannot be well matched with the photosynthetic absorption spectrum of plants, and the efficiency of supplementing light is low; and it produces a lot of heat radiation, which cannot be close to the plants, and the light excitation efficiency for plant growth is not high, and the cost of using it as an artificial light source is very high.
