Latest Key Points of Field Management Techniques for Atractylodes macrocephala
Atractylodes macrocephala is a perennial herbaceous plant and also a traditional Chinese medicinal herb in our country. Atractylodes macrocephala has effects such as strengthening the spleen and stomach, and clearing heat and detoxifying, and the main medicinal part is the rhizome. It holds a relatively important position in traditional Chinese medicine research in our country. Moreover, our country's traditional Chinese medicine industry is very popular, so naturally the planting area of Atractylodes macrocephala is also relatively wide. But how should it be managed after planting? Today, the editor has brought you the field management of Atractylodes macrocephala. Let's take a look below!
1. Intertillage and weeding
Atractylodes macrocephala is a herbaceous plant, and its ability to absorb nutrients and water is not very strong, so after the seedlings emerge, intertillage and weeding should be done in a timely manner. Especially when the young seedlings have just emerged, this is also the growth period of various weeds, so weeds should be removed in time to prevent them from competing for the nutrients needed for the growth of Atractylodes macrocephala. Intertillage is intended to improve soil permeability and enhance the absorption capacity of the roots of Atractylodes macrocephala. Attention should be paid to the depth of intertillage. The first few times can be appropriately deep, and after passing the seedling stage, shallow hoeing should be carried out to prevent damage to the roots.
2. Timely topdressing
During the growth process of Atractylodes macrocephala, the demand for nutrients is relatively large, and the topdressing work throughout the entire growth period must be carried out no fewer than 2 times. The first time is around the budding stage, and the second time needs to be within 7 days after bud removal. Urea or compound fertilizer can be used, and attention should be paid to the amount of topdressing. The total weight per mu should not exceed 50 kg. After each topdressing, water and cover the soil in time to dilute the fertilizer, promote absorption, and improve the soil's fertilizer retention capacity.
3. Water management
The growth of Atractylodes macrocephala has a very large demand for water, so during the planting process we should keep the soil moist to meet the water requirements of Atractylodes macrocephala. Especially when Atractylodes macrocephala grows to the expansion stage, the water demand will further increase, so special attention should be paid to irrigation at this stage. If encountering a high-temperature and drought environment, not only should cooling and shading work be done well, but watering should also be carried out in time. However, it should be noted that water should not be excessive, and in rainy weather, accumulated water should be drained from the field in time.
4. Timely bud removal
Because the medicinal part of Atractylodes macrocephala is usually the rhizome, there is not much need for flowers. In order to prevent flowers from competing for nutrients and reduce nutrient consumption, when Atractylodes macrocephala begins to bud, the flower buds should be gradually removed completely to promote the concentration of nutrients in Atractylodes macrocephala. Bud removal can effectively improve the quality and yield of the roots of Atractylodes macrocephala and further expand one's planting economic benefits. However, it should be noted that when removing buds, there should not be water on the flower buds and leaves.
5. Reasonable straw covering
Straw covering is intended to improve the soil's water and fertilizer retention, prevent soil erosion, increase fertilizer consumption, and raise planting costs. Moreover, reasonable straw covering can also control ground temperature, play a certain insulation role, help Atractylodes macrocephala overwinter, and improve its overwintering survival rate. This ensures the final yield and prevents some unnecessary losses. Materials for covering can include leaves, wheat bran, and so on.
Atractylodes macrocephala has extremely high medicinal value and also has certain preventive and therapeutic effects on some diseases, such as enteritis and liver cancer. It is not only used as an ingredient in traditional Chinese medicine formulas, but is also used to make certain medicinal preparations, so the current market for Atractylodes macrocephala is very good. However, after all, it is a medicinal herb, and planting it will still involve certain risks, so I hope everyone will consider it carefully. That is all for today's introduction.
