IV. Planting techniques of Ephedra

1. Variety selection

There are many varieties of ephedra, about a dozen, but the most widely planted is Middle Ephedra. Its output and quality are very good. Many pharmaceutical factories and manufacturers prefer to purchase Chinese Ephedra. Therefore, both the price and sales channels of Ephedra are guaranteed, followed by Equisetum equisetifolia and Ephedra equisetifolia. Of course, you can make a choice according to your area. It depends on whether to choose drought-resistant or disease-resistant or cold-resistant.

2. Soil preparation and fertilization

Ephedra planting will generally be selected in the deep land with relatively complete soil structure, its permeability is very strong, and the drainage system is perfect, it is best to choose the area close to the water source, so it is convenient for drainage and irrigation, and the land should not choose clayey soil as far as possible. this permeability is not good, not suitable for the growth of ephedra, the soil needs to be refined when preparing the soil, and if possible, turn the land as deep as possible. Finally, when applying sufficient basic fertilizer during land preparation, an average of 4,000 to 5,000 jin of farm manure is needed per mu of land, and about 40 jin of nitrogen fertilizer and 40 jin of potash fertilizer are mixed and scattered evenly in the field.

3. Sowing and raising seedlings

Ephedra seeds are very expensive, so you must be careful when sowing, otherwise sprouting failure is so serious, so we will do corresponding seed treatment before sowing. First, we soak ephedra in warm water of about 30 degrees for three or four hours, and then soak it in Yumaoling solution for about two hours, in order to enhance the resistance of Ephedra. We can stir the seeds with some chemicals at this time, then mix them with a layer of sand and put them at the right temperature to germinate. After three days, most of the seeds will have sprouted white, and then they can be sown. When sowing, we can use hole sowing or strip sowing, the distance between each plant is about 25 cm, the distance between each row is about 30 cm, sprinkle the seeds evenly on the whole ground, and then cover the seeds with thin soil.

4. Field management

The first step in field management is to check whether intercropping and replenishing seedlings are needed. We can pull out only three or four trees where there are more seeds in the field, and then fill the seedlings to a sparse place where they grow. When the seedlings of Ephedra grow to five or six centimeters, we can carry out the first intermediate ploughing and weeding. Because there are more weeds in the growth process of Ephedra, in order not to affect the yield, we have to carry out timely weeding. Then apply 1000 jin of farm manure, 500 jin of urea and 50 jin of phosphate fertilizer to cultivate the soil, and then irrigate it. When there is a relatively heavy rainfall season, we need to go to the field in time to dredge the ditch and then lead Rain Water out. The second fertilization is when ephedra blossoms, which is to promote flowering, but also to let it bear more fruit, so that it will collect a little more seeds. The last is to promote fruit growth, generally using 500 jin of phosphate fertilizer, 50 jin of potash fertilizer and 40 jin of boron fertilizer.

5. Disease control

The common diseases and insect pests of ephedra are standing blight and quenching disease. for standing blight, chlorothalonil is generally sprayed every six to ten days, and it will basically be cured after two or three times. if we had done seed treatment during sowing, it would not have happened, but just in case, we should carefully observe the growth changes of the plant, and then we can spray chlorovir to control it. Ephedra sometimes has some insect pests, such as aphids and inchworms, which can generally be sprayed with dimethoate milk. If it is more serious, it must be sprayed several times to alleviate the disease.

6. Timely harvest

The best growing period of ephedra can be said to be in June, so our harvest time is usually in September. Because ephedra can grow for many years, the way to harvest is to cut off the stem on the ground with a sickle, then clean the sediment from the stem, cut it into small sections to dry, and finally pack it.
