The artificial planting method of Herba Epimedii has great potential for development.

Epimedium brevicornu Maxim., Epimedium brevicornu Maxim Epimedium sagittatum(Sieb. et Zucc.) Maxim.、Epimedium pubescens.Maxim. or Epimedium koreanum Nakai. Born under the forest, ditch edge shrubs or hillside damp, Shaanxi, Gansu, Shanxi, Henan, Qinghai, Hubei, Sichuan and other regions are cultivated, the whole grass for medicinal purposes.

Epimedium is one of the oldest traditional Chinese medicines, which was first recorded in Shennong Bencao Jing. Epimedium is also one of the most widely used traditional Chinese medicines, which has been widely concerned at home and abroad. In addition to its traditional usage of tonifying kidney, strengthening yang and eliminating rheumatism, Epimedium is also commonly used in clinical treatment of osteoporosis, climacteric syndrome, breast mass, hypertension, coronary heart disease, immune enhancement, anti-aging, anti-tumor, anti-AIDS and so on. It has great research and development potential. In the past ten years, the medicinal material market has been selling well, the price has risen, and the wild variety resources have been over-exploited for years, which has been seriously damaged, and now it is far from meeting the production needs. Therefore, the prospect of artificial cultivation is imminent.

1. Growth Habits

Likes to be cloudy and humid, soil humidity 25~30%, air relative humidity 70~80% is appropriate, light is sensitive, avoid direct sunlight, require shading degree of about 80%, strict requirements for soil, neutral acid or slightly alkaline, loose, containing humus, rich in organic matter soil oily sandy loam is good, elevation in 450~1200 meters low, middle mountain shrubs, sparse forest or forest edge semi-shade environment suitable for growth.

II. Cultivation techniques

(1). Land selection and preparation

Natural conditions of shady slope or semi-shady and semi-sunny slope are selected, the slope is below 35 degrees, and the soil is slightly acidic leaf humus soil, black loam and black sandy loam. Broad-leaved forest or coniferous and broad-leaved mixed forest and fruit trees can be used for economic undergrowth cultivation. The understory turf is removed, and the strip beds with the width of 120-140 cm and the height of 12-15 cm are formed along the slope, and seedlings are planted in the horizontal groove, and the ditch depth is 6-10 cm.

(2). planting method

Vegetative propagation and transplantation

1. Dormancy period transplanting: before budding in April to May in spring or when stems and leaves on the ground wither in September to October in autumn, dig underground rhizomes, cut stem sections with buds into 8-10cm sections, retain 1-2 spores in each section, plant in a strip bed after treatment with gibberellin and rooting powder, plant spacing 15 cm ×20 cm, cover with fine soil 5 cm, and cover with wet leaves 3-5 cm after stepping.

2. Growing period transplanting: summer 6-8 months high temperature and rainy under the forest cultivation. Transplant wild plants with soil, dig and plant within 24 hours, preferably after cloudy or rainy days. Plant spacing 20 cm ×25 cm, soil cover 3-5 cm,

After treading, cover the leaves 3-5 cm. This cultivation method does not slow down seedlings, and the survival rate is as high as 85%. And rhizome tiller bud grows fast, the next spring branches more, high yield.

(3). field management

1. Supplement seedlings: after emergence in February to March of the next spring, timely pull out dead seedlings, weak seedlings, sick seedlings, and supplement seedlings on cloudy days to ensure the basic number of seedlings.

2. Intertillage weeding: combined with intertillage weeding, to the extent that there are few weeds on the surface of the plot. In the growing season, weeding can be done once every 10 days; in autumn and winter, weeding can be done once every 30 days.

3. Irrigation and moisture conservation: Epimedium likes moist soil environment, drought will cause its growth stagnation or dead seedlings. If it is sunny for 5-6 days in summer, artificial watering must be carried out in the morning and evening.

4. Reasonable fertilization: in October to November of the first year, the base fertilizer is applied when the soil preparation is opened, generally applying 1000-3000 kg/mu. The fertilizer shall be applied once or twice from the end of March to June of the next year. Generally, the application amount of inorganic nitrogen fertilizer shall not exceed 5kg/mu, and the organic compound fertilizer shall be 10- 30kg/mu; the bud promotion fertilizer shall be applied once from October to November of the next year, and the farm manure shall be applied 1000kg/mu, or the organic fertilizer shall be 10- 20kg/mu; the soil fertilizer shall be supplemented in time after each harvest, and the farm manure shall be applied 1000- 2000kg/mu, or the organic compound fertilizer shall be 20- 30kg/mu. The base fertilizer is evenly spread on the surface of the ridge after the ridge is opened and before the planting, and then turned into the soil, and then carefully mixed. When digging the "hole" or "strip" after the ridge is opened and before the planting, the fertilizer is evenly placed in the "hole" or "strip", and the fertilizer is mixed with the surrounding soil evenly. Topdressing is mainly applied to "acupoints". When topdressing, do not apply fertilizer to newly unearthed branches and leaves. It should be applied close to the base of the plant and covered or uncovered depending on the type of fertilizer.

III. Disease and pest control

1. Leaf brown spot blight

[Symptoms] Leaf brown spot blight damages leaves. The diseased leaves are blotchy, initially brown, surrounded by yellow halos. After expansion, the spots were irregular, with reddish-brown to brown edges, grayish brown in the middle, grayish brown in the late stage, contracted and black granules appeared, which were conidia of the pathogen. The pathogen occurred in seedling stage and adult stage of Epimedium, and more serious damage occurred in seedling stage.

[Prevention and control] ① Remove sick bodies and destroy them in time to reduce pollution sources. (2) In the early stage of disease, pesticides can be applied to prevent and control. The commonly used pesticides are 50% Zineb WP 600 times, 50% Tuijunte WP 800 times, 1:1:160 Bordeaux mixture, 30% copper oxychloride 600~800 times, 50% carbendazim WP 500~600 times, 70% thiophane methyl WP 800~1000 times, 75% chlorothalonil WP 500~600 times. These agents should be used alternately to avoid resistance.
