Problems solved by technology

[0004] Stevia rebaudiana seeds are easily affected by adverse environments such as low temperature, chilling damage, and high temperature during the process of sowing seedlings, resulting in the loss of germination ability, long germination time, reduced germination rate and germination potential, irregular seedling emergence, and poor seedling growth. Seedling mortality is high, which affects the germination of stevia and field transplanting in the later stage

Embodiment 1

[0036] A method for growing seedlings of stevia rebaudiana, comprising the following steps:

[0037] A. Select and process seeds

[0038] (a1) Seed selection: select Stevia rebaudiana seeds that are complete, full in granules, undamaged in the epidermis, and high in variety performance;

[0039] (a2) Disinfection of the surface of the seeds: put the seeds into the disinfectant solution, soak them for 2 hours, rinse them twice with clean water, then soak them dry with dry gauze, and set aside;

[0040] (a3) Seed soaking: put the sterilized seeds in warm water at 35 degrees Celsius, soak for 30 hours, in order to prevent bacterial infection, filter every 10 hours, rinse the seeds with clean water, replace them with warm water and continue soaking, and remove the seeds floating on the water surface;

[0041] (a4) Acceleration of germination: Stir and mix the soaked seeds with wet fine sand and wet plant ash to make it wrap the surface of the seeds, then irradiate them under an u...

Abstract

The invention relates to the technical field of agricultural planting and discloses a stevia rebaudiana seed seedling cultivation method. The method includes steps: A, seed selection and treatment; B,seedbed preparation; C, seed sowing; D, seedling cultivation period management; E, transplanting. The stevia rebaudiana seed seedling cultivation method has advantages that by adoption of trays for seedling cultivation, the temperature and moisture in a seedling cultivation process are strictly controlled according to characteristics of stevia rebaudiana seeds, nutrient solution is sprayed regularly to guarantee nutrient supply sufficiency, and the seedling survival rate and the germination rate of the stevia rebaudiana seeds are increased.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a stevia seed seedling raising method. Background technique [0002] The main component of stevia dry leaves is steviol glycoside, which not only has high sweetness and low calorie, but also has certain pharmacological effects. Stevia sugar mainly has the effects of treating diabetes, controlling blood sugar, lowering blood pressure, anti-tumor, anti-diarrhea, improving immunity, and promoting metabolism. It has a good effect on controlling obesity, regulating gastric acid, and restoring nerve fatigue. It also has a significant effect on children's dental caries, and the most important thing is that it can eliminate the side effects of sucrose. Normal people have no side effects on the human body when the daily intake of stevia is below 4 mg / kg body weight. In South America, Southeast Asia, and the Far East, steviol glycosides are widely used in the fields of food...
