Embodiment 1

[0028] The test was carried out in the plant factory of Jiangxi Academy of Sciences from March 2018 to February 2019. The indoor temperature was 20-22°C, the humidity was 80%, and the CO 2 The concentration is 500mL / L, and the photoperiod is 14h / d. Use the seedling sponge in the plant factory to raise seedlings, soak the sponge with water, sow the seeds directly in the seedling sponge, keep away from light for 2 days, and carry out different light treatments after the seeds germinate; when the seedlings grow to two leaves and one heart, choose the same growth The seedlings were transplanted in hydroponics, and the nutrient solution used Hogland nutrient solution.

[0029] Three-dimensional cultivation, the hydroponic frame is divided into 3 layers, each layer can plant 36 Uttas, and each layer is set with a light quality ratio. From 10 days after transplanting, the growth indicators were measured every 10 days, including crown length, crown width, leaf length, leaf width, ste...

Abstract

The invention provides a water culture planting method of Wuta-tsai and belongs to the technical field of plant culture. The water culture planting method of Wuta-tsai comprises the steps as follows:artificially adjusting the light quality ratio in the water culture process of the Wuta-tsai, wherein the light quality ratio is selected from 8:1 of red light to blue light or 20:5:1 of red light, blue light and ultraviolet. According to the method, by adjusting the type and the proportion of LED light in the water culture process of the Wuta-tsai, the content of vitamin C, protein, soluble saccharides, flavonoids and total chlorophyll in the Wuta-tsai can be significantly increased, and the quality of the Wuta-tsai can be significantly improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a hydroponic planting method of Utah cabbage. Background technique [0002] Illumination is one of the basic elements of plant growth and development, and has an important impact on the production and quality of crops. Light-emitting diode (LED for short) is a new type of semiconductor light source, which has the advantages of small size, low heat generation, high energy efficiency, and high energy efficiency. With the advantages of monochromatic light emission and long lifespan, it has become an ideal tool for studying the effects of light on plant growth and development, and plays an important role in protected horticulture research and production applications. Light quality has an important impact on plant photosynthesis, morphogenesis and quality formation. Red light is an important energy source for plant photosynthesis. Plants accumulate more dry matte...
