The method for improving the survival rate and yield of Epimedium brevicornum seedlings according to claim 1, characterized in that: The regular fertilization and irrigation specifically includes: After the epimedium seedlings emerge, apply top dressing to the leaves of the epimedium using fully decomposed soybean water, 0.3% urea and potassium dihydrogen phosphate. Apply foliar fertilizer 2-3 times per growing season, with an interval of 7 days between each application. For the last application, spray the leaves of Epimedium with a 0.3% potassium dihydrogen phosphate solution. When the moisture content of the nutrient substrate is below 40%, water the Epimedium seeds using irrigation equipment to maintain the moisture content of the nutrient substrate at 40%.

7. The method for improving the survival rate and yield of Epimedium brevicornum seedlings according to claim 5, characterized in that: The bactericidal component of the traditional Chinese medicine is composed of the following raw materials in parts by weight: Dandelion, 3-6 parts; Chicken blood vine, 5-8 parts; Castor bean leaves, 3-6 parts; Corydalis rhizome, 2-4 parts; Mixed onions and garlic, 6-10 servings; Coptis chinensis, 3-5 parts; Evodia rutaecarpa, 1-4 parts; Artemisia argyi, 5-10 parts; Sichuan pepper water, 5-8 parts; Wood ash, 20-30 parts.

8. The method for improving the survival rate and yield of Epimedium brevicornum seedlings according to claim 6, characterized in that: The harvesting of Epimedium seeds and the removal of immature seeds specifically includes: Seeds of Epimedium are collected from March to May. Select Epimedium seeds with cracked or already cracked seed coats. Rub the Epimedium seed to separate the Epimedium seed from the seed shell, and put the separated Epimedium seed into water to separate the Epimedium seed from the water; Stir evenly for 5-15 min, remove the immature Epimedium seed floating on the water surface, and obtain the mature Epimedium seed. Sterilize the Epimedium seed, then soak in the growth-promoting solvent for 3-5 min, and dry in a cool, ventilated and breathable environment after taking out.

9. The method for improving the survival rate and yield of Epimedium brevicornum seedlings according to claim 8, characterized in that: The sterilization of the seed specifically includes: Prepare the disinfectant by mixing naphthalene acetic acid with a concentration of 40 mg / L and indole butyric acid with a concentration of 33 mg / L at a weight ratio of 2:3 to obtain the disinfectant; Heat the mature Epimedium seed in a microwave oven to make the Epimedium seed absorb energy and heat up, and sterilize the Epimedium seed quickly. Then take out the Epimedium seed, cool it, and then soak the Epimedium seed in the disinfectant for 30-60 min.
