Problems solved by technology

[0003] In the process of greenhouse planting, due to climate, weather changes or poor light transmittance of the greenhouse, there is a phenomenon that the intensity of light in the greenhouse cannot well meet the growth needs of leafy vegetables, and different types of leafy vegetables and different growth stages have different wavelengths. The demand for light is also different. It is difficult to adjust the light source according to the growth stage of the leafy vegetables in the prior art, and it is difficult to obtain the best light conditions for the growth of the leafy vegetables.

Abstract

The invention provides a vegetable plantation method. An LED light source is used to irradiate leaves of vegetables, light emitted by the LED light source including blue light and red light, and the proportion of light energy of blue light to light energy of red light is 0.7-1.5:1. Under irradiation in the light energy proportion, leafy vegetables grows rapidly and vigorously, the production period can be shortened, and the output is increased. The invention also provides the LED light source, the LED light source comprises a glue light chip and mixing fluorescent powder fixed to the blue light chip, the mixing fluorescent powder comprises red fluorescent powder and green fluorescent powder in the weight ratio of 1:1-1.5, and the LED light source can be applied to vegetable plantation.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a vegetable planting method and an LED light source. Background technique [0002] Leafy vegetables are a type of fast-growing vegetables that mainly produce fresh green leaves, petioles and tender stems. Common ones include spinach, rapeseed, lettuce, lettuce, Chinese cabbage, bitter chrysanthemum, cabbage heart, kale (kale), and chrysanthemum chrysanthemum. , celery, water spinach, lettuce leaves, green amaranth, watercress, shallots, leeks, radish sprouts, fungus, coriander, potherb mustard, red beet, shepherd's purse, bitter cabbage, etc. The light absorbed by the leaves is mainly visible light, that is, the assimilation of energy in the 380-710nm range of the solar spectrum. Red light and blue-violet light are most absorbed by chlorophyll in sunlight, which is manifested as strong photosynthesis and forming. Light with different wavelengths, properties and energi...
