The time of planting ephedra is very important. When is the best time to plant ephedra?

Ephedra is a traditional Chinese herbal medicine, which is used to treat asthma, fever, chills, hypotension, sweating and colds. However, the planting operation and control of Ephedra in China are very strict now, because it is also the raw material for making ice, just like roses. Therefore, in order to better avoid adverse effects, it is necessary to strengthen the scope of supervision, but if all normal judicial procedures can be followed, how should ephedra be planted? Let's study and train together.

1, species selection

There are many kinds of ephedra, about a dozen, but the most common one is ephedra, with good yield and quality. Many pharmaceutical companies and manufacturers prefer to recycle ephedra, so the price and marketing channels for planting ephedra are guaranteed, followed by Casuarina equisetifolia and Casuarina equisetifolia. Naturally, you can choose according to your region, depending on whether you choose drought resistance, disease resistance or cold resistance.

2. Tillage and fertilization

Ephedra is generally planted in places with deep soil layer, fine soil, strong permeability and perfect drainage facilities. It is best to be located near the water source, which is convenient for irrigation, and the land resources do not need to choose cohesive soil as much as possible, and the permeability is not very strong, which is not suitable for the growth and development of ephedra. In the case of ploughing, the soil layer must be thinned, the land resources should be loosened as much as possible, and finally the base fertilizer should be applied in the case of ploughing. On average, an acre of land needs about 4,000 to 5,000 kilograms of organic fertilizer, 40 kilograms of base fertilizer and 40 kilograms of potash fertilizer to be evenly scattered in the ground.

3. Before sowing seedlings

The seeds of ephedra are very expensive, so be careful when sowing, otherwise the damage will be more serious if the germination is unsuccessful, so the corresponding seed solution will be made when sowing. First, people will soak ephedra in warm water of 30 degrees for three or four hours, and then pick it up and soak it in the water solution in front of Miao Ling for two hours. In order to better improve the resistance of ephedra, seeds can be mixed with some drugs at this time. Then mix a layer of gravel and put it at a suitable temperature to promote teeth. After three days, most of the seeds have germinated and turned white, so you can start sowing. In the case of sowing, we can choose hole sowing or hole sowing. The spacing between trees is about 25 cm, and the spacing between rows is about 30 cm. Spread the seeds evenly all over the ground and then cover them with thin soil.

4. Cultivation techniques

The first step of cultivation technology is to ask whether it is necessary to replenish seedlings. We can only pull out the other three or four plants in the area where seeds germinate more, and then replant the seedlings in the area where seedlings are less. When the seedlings grow to five or six centimeters, we can weed for the first time. Because there will be more weeds in the whole growth and development process of ephedra, in order not to endanger production, weeding should be carried out immediately, and then topdressing with 1000 kilograms of organic fertilizer. In the heavy precipitation season, everyone must go to the field to drain the drainage ditch immediately, and then draw the precipitation out. The second fertilization was carried out when ephedra was in full bloom. This time is to better promote the flowering period, but also to better make it bear more fruits, so that more seeds will be collected. The ultimate goal is to promote the development of fruits. Generally, 500 kilograms of phosphorus and potassium fertilizer, 50 kilograms of potassium fertilizer and 40 kilograms of boron fertilizer are used.

5. Prevention of pests and diseases

The common diseases of ephedra are bacterial wilt and verticillium wilt. For bacterial wilt, mancozeb is usually sprayed once every six to ten days, and most of them will recover after two or three times. But if the problem of verticillium wilt is solved under the condition of sowing, most of it will not happen easily. But for better prevention, we need to carefully observe the growth and transformation of plants, and then spray Bai Weiling for prevention. Ephedra sometimes has some pests and diseases, such as budding insects and inchworms. Generally, dimethoate milk can be sprayed. If it is serious, it needs to be sprayed several times to relieve the condition.

6, moderate harvest

The best growth period of Ephedra is June, so the harvesting time is generally September. Because Ephedra can grow and develop for many years, the harvesting method is to cut off the stems on the road with a long knife, then clean up the fine sand of the stems, cut them into small pieces to dry, and finally package them.
