Detailed Explanation of Field Management Techniques for Salvia miltiorrhiza
Salvia miltiorrhiza (Danshen) is a fairly well-known medicinal herb in China, and its roots can be used as medicine. Salvia miltiorrhiza is also a common wild medicinal herb, but as market demand for it has gradually increased, a shortage of supply has begun to appear, so the area of artificial cultivation has also grown larger and larger. Although Salvia miltiorrhiza is relatively easy to keep alive, it still requires a certain amount of management, so how should it be managed when growing Salvia miltiorrhiza? Let's take a look below!
1. Fertilization Management
Salvia miltiorrhiza is generally planted in winter and autumn, and usually after spring arrives it enters the greening stage. Salvia miltiorrhiza is an annual medicinal herb and needs at least 8 months before it can mature and be harvested. During the cultivation of Salvia miltiorrhiza, fertilizer must be applied as a top dressing at least three times. The top dressing at the greening stage is the first, the second is around Qingming Festival, and the last is around the end of June. Decomposed farmyard manure can be used for all of them, and the fertilization method can be hole application or furrow application.
2. Loosening the Soil and Weeding
After planting, Salvia miltiorrhiza grows relatively slowly in the early stage, so in order to promote its growth, we must do a good job of loosening the soil and weeding during cultivation. Improve soil permeability and promote nutrient uptake by Salvia miltiorrhiza, and the number of weedings must not be fewer than three. Weeding prevents weeds from competing with Salvia miltiorrhiza for nutrients and affecting its growth. When loosening the soil, pay attention to the force used to avoid damaging the roots, and try to carry out soil loosening and weeding together with top dressing.
3. Water Management
Salvia miltiorrhiza needs a certain amount of water to grow, but it is not tolerant of waterlogging, so during its growth period pay attention to the field's moisture content. Do a good job of drainage in time, and pay attention to clearing the drainage ditches to prevent blockage of the ditches from causing poor drainage and waterlogging damage. Pay attention to observing weather changes, water in time during drought, and drain water in rainy weather. When watering, the furrow irrigation method can be used; avoid furrow irrigation at noon and speed up the watering.
4. Flowering Stage Management
During the flowering stage of Salvia miltiorrhiza, the work of retaining seeds must be done well. Some Salvia miltiorrhiza plants need to keep their flowers in order to collect seeds, but plants that do not need to retain seeds should have their flower clusters pinched off in time. Ensure that the nutrients of Salvia miltiorrhiza are concentrated in the roots, and the removal of flower clusters should be timely and frequent. It is best to remove the flower clusters as soon as they emerge; for plants kept for seed, retain the robust flower clusters with strong growth, and promptly remove flower clusters that grow slowly and are poorly nourished. In this way, the quality of the seeds is improved and the growth of the plants is strengthened.
5. Plant Management
Although Salvia miltiorrhiza is mainly used as medicine from its roots, the aboveground plants must also be managed well during cultivation. If permeability is too poor, the plants are prone to lodging, which will affect the expansion of the tubers. Tillering of Salvia miltiorrhiza is unfavorable to plant growth, especially in the later stage, so after the flowering stage of Salvia miltiorrhiza all tillers should be removed in time. In addition, for plants kept for seed, after the seeds are harvested, the old stems should be pruned in time so that the plants have the ability to regenerate.
The above are the field management methods for Salvia miltiorrhiza. Salvia miltiorrhiza is a famous traditional Chinese medicinal herb, and China's oldest medical art is traditional Chinese medicine. Therefore, market demand for Salvia miltiorrhiza is still on an upward trend, and the market price only rises and does not fall. Thus Salvia miltiorrhiza is also a cultivation project with relatively good prospects. That is all for today's introduction; this article is for reference only, and I hope it can also help everyone.
