Problems solved by technology

Greenhouse pears have developed rapidly in coastal areas due to their advantages of regulating fruit maturity, increasing benefits, and preventing natural disasters. However, studies have shown that due to insufficient photosynthesis, the quality of pears cultivated in greenhouses generally suffers from a decline in fruit quality.

Abstract

The invention provides a method for improving the sweetness of pears by using LED lamps. The method is characterized by providing three lights including red, blue and yellow in a certain ratio by combined LED light sources for improving the sweetness of the pears, wherein the light emitting wavelength of a red light LED ranges from 600nm to 680nm, the light emitting wavelength of a blue light LEDranges from 400nm to 450nm, and the light emitting wavelength of a yellow light LED ranges from 550nm to 600nm. The accumulation of soluble proteins of the pears is increased by red light and blue light, and the accumulation of soluble sugars is increased to the maximum extent by LED yellow light, so that the pears are higher in sweetness and better in taste. The red light and the blue light are beneficial to the accumulation of the proteins and various enzymes, the yellow light is beneficial to the accumulation of sugars, and due to the enrichment of the enzymes, the conversion of the sugarscan be further improved, and the content of fructose can be increased, so that the tastes and quality of the pears are greatly improved under the synergistic effect of the three different lights.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a method for improving the sweetness of pears by using LED lights. Background technique [0002] Plant growth is inseparable from light, and photosynthesis can only be completed under light conditions. When other conditions remain unchanged, crop yield is directly related to photosynthetic products. With the continuous development of facility agriculture technology, plant lighting has a very broad application prospect. As a solid-state semiconductor device, LED can convert the store into visible light. The difference from ordinary Guangyuan such as halogen lamps is that it has a narrow spectral range and extremely low energy consumption, which is only about one-third of the energy consumption of ordinary energy-saving lamps. Over the years, researchers at home and abroad have conducted a lot of exploration around the application of LED light sources in the field of plant l...
