Field management of salvia miltiorrhiza

Salvia miltiorrhiza is a famous medicinal material in China, and its roots can be used as medicine. Salvia miltiorrhiza is also a common wild medicinal material, but with the increasing market demand of Salvia miltiorrhiza, the supply is in short supply, so the artificial planting area is also increasing. Salvia miltiorrhiza is easy to survive, but it also needs some management. So how to manage planting salvia miltiorrhiza? Let's have a look!

1, fertilization management

Salvia miltiorrhiza is usually planted in winter and autumn, and usually turns green after spring. Salvia miltiorrhiza is an annual medicinal material, which takes at least 8 months to mature and harvest. In the process of planting salvia miltiorrhiza, fertilization should be carried out at least three times. The first time was the top green period, the second time was around Tomb-Sweeping Day, and the last time was around the end of June. All fertilizers can use decomposed farmyard manure, and the fertilization method can be hole application or furrow application.

Step 2 loosen the soil and weed

The growth rate of Salvia miltiorrhiza is relatively slow in the early stage after planting, so in order to promote the growth of Salvia miltiorrhiza, soil loosening and weeding should be done well in the planting process. Improve soil permeability, promote nutrient absorption of Salvia miltiorrhiza, and weed for at least three times. Weeding is to prevent weeds from competing with Salvia miltiorrhiza for nutrients and affecting the growth of Salvia miltiorrhiza. Pay attention to avoid damaging the root system when loosening soil, and try to loosen soil and weed together for topdressing.

3. Water management

Salvia miltiorrhiza growth needs a certain amount of water, but it is not tolerant to waterlogging. Pay attention to the field water content during the growth period of salvia miltiorrhiza. Do a good job of drainage in time, pay attention to cleaning the drainage ditch, and prevent waterlogging caused by poor drainage and channel blockage. Observe the weather changes, water it in time when it is dry, and drain it in rainy days. Trench irrigation can be used when watering, and it should be avoided at noon to speed up irrigation.

4. Flowering management

During flowering, the seeds of Salvia miltiorrhiza should be kept. Some salvia miltiorrhiza plants need to leave flowers when collecting seeds, but those plants that don't need seeds should pinch off inflorescences in time. Ensure that the nutrition of salvia miltiorrhiza is concentrated in the roots, and the removal time of inflorescences should be timely and frequent. It is best to pull out the inflorescence as soon as it is pulled out. Plants planted should maintain strong inflorescences, and slow-growing and malnourished inflorescences should be removed in time. Thereby improving seed quality and promoting plant growth.

5. Factory management

Although salvia miltiorrhiza is mainly used as medicine by roots, it is necessary to manage the aboveground plants when planting. If the permeability is too poor, plants are prone to lodging, which affects tuber expansion. The tillers of Salvia miltiorrhiza are unfavorable to the growth of plants, especially in the later stage, so all the tillers of Salvia miltiorrhiza should be pulled out in time after flowering. Moreover, after the seeds of plants are harvested, the old stems should be cut off in time to allow the plants to regenerate.

The above is the field management method of salvia miltiorrhiza. Salvia miltiorrhiza is a famous Chinese herbal medicine, and the oldest medical skill in China is traditional Chinese medicine. Therefore, the market demand of salvia miltiorrhiza is still on the rise, and the market price is only increasing. So salvia miltiorrhiza is also a promising planting project. Let's call it a day.
