Abstract

The invention discloses a method for controlling and controlling the flowering of stevia seedlings by LED lights, comprising the following steps: (1) selection and installation of LED lights: selecting a combination of 660nm red light with a light quality of 75% and 460nm blue light with 25% LED lights, total light intensity 150‑180μmol / (m 2 .s), the output power is 30‑40W; LED lights are installed in the nursery facilities, so that the LED lights cover all the seedbeds in the nursery facilities; (2) LED lighting treatment: after stevia cuttings, turn on the LED lights in the middle of the dark period for light Treatment: The temperature is controlled at 15-30°C and the relative humidity is 75-85% during the whole process from cutting to seedling raising. Stevia rebaudiana cutting propagation using the method can reduce the waste of seedling raising materials caused by budding and flowering, save production costs, accelerate the stevia breeding work and the cutting seedling breeding speed in production, and increase the annual multiplication quantity.

Description

technical field

[0001] The invention relates to the technical field of Stevia rebaudiana asexual propagation, and more specifically relates to a method for controlling and controlling the flowering of Stevia rebaudiana seedlings by LED lighting. Background technique

[0002] Stevia, scientific name: Stevia rebaudiana (Bertoni) Hemsl, native to the subtropical region of South America, is a perennial herb of the genus Stevia in the family Asteraceae. Steviol glycoside extracted from stevia leaves is known as "natural saccharin" and the "third sugar source" in the world. It is a natural, high-sweet, low-calorie, new type of green health-care sweetener. An ideal substitute for beet sugar. Steviol glycosides have good anti-cancer activity, can reduce the blood sugar concentration of type 2 diabetes, control high blood pressure, and have great potential in the development of medical and health care products; currently they are widely used in food, beverage, pharmaceutical, daily ...
