A Detailed Guide to the Latest Field Management Methods for Angelica sinensis
In ancient times, Angelica sinensis symbolized the wanderer's return home, or the husband who had gone out to seek official rank and glory coming home, meaning the family's longing for loved ones who were far away. But in fact, Angelica sinensis is also a traditional Chinese medicine, slightly bitter in taste. It is said that when a woman comes of age or a man comes of age, if Angelica sinensis is stewed into soup and drunk, it can promote bone growth. In addition, Angelica sinensis has a very good preventive and therapeutic effect on gynecological diseases, and is very popular among women. Angelica sinensis is now grown in many places. So today, what Qinnongwang wants to share with you are the field management methods for Angelica sinensis. Friends who need them can save this.
1. Thinning and Replanting Seedlings
The first task of field management is to check for gaps and fill them in. About fifteen days after planting Angelica sinensis, we need to inspect the field once to see where seedlings are missing and where the seedlings are growing too densely. For the dense areas, we need to thin the seedlings so that the spacing between each plant is about 20 cm. At the same time, if the plants are very dense, we generally keep only three to four seedlings per spot and pull out the rest. In places that are too sparse or where seedlings are missing, we replant them, and finally water once.
2. Intertillage and Weeding
Angelica sinensis grows very slowly during the seedling stage, but weeds grow relatively quickly. After all, the soil has sufficient fertility, so if weeding is not carried out, most of the nutrients will be absorbed by the weeds. Under normal circumstances, weeding needs to be done at least three times. If there are especially many weeds in the field, it may need to be done four or five times. The first weeding is about four to five days after the seedlings have just emerged, the second is after we check and replant the seedlings, and the third is when the plants have grown to about 30 cm. Intertillage and weeding are not only for reducing nutrient consumption, but can also enhance soil permeability, improve the plants' immunity, and accelerate the plants' growth rate.
3. Fertilizer and Water Management
Fertilizer and water management for Angelica sinensis can be said to belong to the same period. Generally, aside from the base fertilizer, three fertilizations are needed, and each fertilization is somewhat large in amount, because it needs a large amount of nutrients for the tubers to expand. Also, after each fertilization, watering is needed. This can avoid the problem of burning the plants caused by incorrect fertilization methods. At the same time, the growth of Angelica sinensis also has a relatively large demand for water. After all, tuber growth requires a water supply. The types of fertilizer used each time are about the same, generally a three-element compound fertilizer of potassium fertilizer, phosphate fertilizer, and nitrogen fertilizer. Of course, farmyard rotted manure or organic fertilizer can also be used instead.
4. Branch and Leaf Trimming
After Angelica sinensis has grown for a certain period, the lower branches and leaves will gradually turn yellow, age, and even wither. If they are not removed in time, they may cause disease in the plants and affect the yield of Angelica sinensis. So we remove the yellowing branches and leaves at the bottom. Next, where the branches and leaves are very lush, a small portion also needs to be removed to maintain a certain density. Doing this can both reduce nutrient consumption and enhance the permeability of the field.
5. Field Cleaning
After each weeding, pest removal, branch and leaf pruning, and harvest, a lot of debris will be left in the field. We need to clean up the debris in the field in time. If it continues to accumulate, it will cause the plants to be infected with viruses and lead to a serious reduction in yield. So we need to clear the debris out of the field and then burn it with a large fire.
