The latest course of planting techniques and methods of Epimedium

Herba Epimedii is a perennial herb of the genus Epimedium of Berberaceae, born in forests, shrubs on the edge of gullies or in shady and humid slopes. It is cultivated in Shaanxi, Gansu, Shanxi, Henan, Qinghai, Hubei and Sichuan, and the whole grass is used for medicinal purposes. It has high medicinal and cultivation value. Let's take a look at the planting techniques of Herba Epimedii.

Growth habits of Herba Epimedii

Epimedium likes shade and dampness, the soil moisture is 25%, and the air relative humidity is 70%. It is sensitive to light, avoids direct sunlight, requires shading of about 80%, and is strict with the soil. it is better to use neutral acid or slightly alkaline, loose, soil oil sand loam rich in humus and organic matter, and it is suitable to grow in low, middle mountain shrub, sparse forest or semi-shaded forest edge at 450-1200 meters above sea level.

Propagation techniques of Herba Epimedii

1. Rhizome propagation

① rhizome selection: to dig wild Epimedium rhizome as propagation material, it is necessary to choose the root system is developed and sturdy, the pulp gas is sufficient, there are many whisker roots, the diameter of the root is more than 0.3cm, the overwintering bud is full, and there is no infection of diseases and insect pests.

② harvest and storage: the wilting period of Herba Epimedii is from the end of September to the middle of October, and the harvest period of rhizome is carried out here. Cut the excavated rhizome into small segments 10 to 15 centimeters long, each section with more than 2 winter buds, tie it and set it aside.

2. Seed propagation

① seed harvest: the mature period of Epimedium seed is from the end of May to the first ten days of June. When the pericarp is about to open and the seeds are exposed to brown, the fruit should be picked in time, picked with ripening, threshed, bumped out of impurities and stored in time. The selected seeds are required to be fully mature, full and complete in shape, without pathogenic bacteria, with a purity of 80%, a thousand-seed weight of 4.5 to 4.7 grams, no mildew, and a germination rate of more than 90%.

② seed storage: the life of Epimedium seed is short, so it should be sowed immediately after harvest. In special cases, after the seeds are selected, fine river sand or fine river sand mixed with humus soil or humus soil can be mixed with seeds for storage. First disinfect the matrix with carbendazim, then fully mix the matrix and seeds at 3:1, put them in a wooden box and store them in a cool and dry place with a rain shelter, which should be checked frequently to prevent fever, lack of moisture, mildew, etc., and the storage period is about 2 months.

Breeding techniques of Herba Epimedii

The main results are as follows: 1. Choose the natural conditions of shady slope or semi-shady and semi-sunny slope, the slope is less than 35 ℃, and the soil is slightly acidic leaf humus soil, black loam soil, black sand loam soil, which can be cultivated under broad-leaved forest, coniferous and broad-leaved mixed forest and fruit tree economic forest. The sod on the ground under the forest was taken up and made into a strip bed with a width of 120 cm 140 cm and a height of 12 cm 15 cm. The seedlings were planted in horizontal trenches with a ditch depth of 6 cm and 10 cm.

2. Sowing time: the life span of Herba Epimedii seeds is short, so it should be sowed immediately after the seeds are collected in the middle of June. Seeds stored under special circumstances should also be sown before freezing in the same year. Under special circumstances, the seeds can be sown after thawing in the spring of next year.

3. Sowing seedlings: Herba Epimedii is sown on the bed to dig a shallow groove 3 to 5 centimeters deep, spread the bottom of the trough with sifted fine humus soil, and then sow seeds. After sowing, cover 0.5 cm with fine humus sifted, and then cover with a layer of fallen leaves and other things to maintain soil moisture. Water thoroughly at one time before sowing or after covering the soil. The sowing rate is 10 to 15 grams per square meter.

4. Strip sowing and raising seedlings: Epimedium strips are sown on the bed and trenched across the bed, with a row spacing of 10 cm and a depth of 3 cm. After opening the ditch, step on the bottom grid, and then sow seeds in the ditch, covering the soil with a thickness of 0.5 cm, covering fallen leaves and so on. The sowing rate is 10 grams per cubic meter.

5. Raising seedlings under the forest: under the mountain forest, the gentle slope should be selected, the shrubs and weeds under the forest should be cleaned up, and the dense trees and branches should be thinned properly so that the canopy density is about 0.5-0.7. Then make a bed with a width of 1.2 meters and a height of 20 centimeters and 25 centimeters along the slope slope, apply base fertilizer, and sow seeds according to the method of raising seedlings on flat land. Under the mountain forest, the rhizome seedlings are raised, the shrubs and weeds under the forest are removed, and the planting belt is made along the contour line. The soil is planed and loosened according to the bandwidth of 30cm to 50cm, and the stems and roots are picked out and then planted.
