The Latest Field Management Tips for Angelica Dahurica in One Article
Angelica dahurica is a perennial herb in the Apiaceae family and a traditional Chinese medicinal material in China. The main medicinal part is the root of Angelica dahurica, which has effects such as draining pus and promoting tissue regeneration, activating blood circulation and removing dampness. It can be used to treat common minor ailments such as colds and headaches, and is also a major spice. It is mainly grown on a certain scale in northern China, so how should Angelica dahurica be managed during cultivation? Below, the editor brings you the field management techniques for Angelica dahurica. Let's take a look!
1. Thinning and Final Spacing
During the seedling stage, Angelica dahurica grows very slowly, so we also need to do a good job of thinning and final spacing during the seedling stage. It is not suitable to do this in the year the seedlings break through the soil. In the second year, during the spring green-up period, thinning should begin once the seedlings grow to about 6 cm, following the principle of keeping the strong and removing the weak, and thinning again after about 1 month. Then, in mid-April, when the seedlings reach 15 cm in height, final spacing should be carried out, controlling the plant spacing of the seedlings at about 14 cm. If sowing is done in holes, then no more than 3 plants should be kept per hole. This improves field ventilation and light penetration. When setting the final spacing, attention should be paid to pulling out excessively vigorous seedlings to prevent early bolting.
2. Intertillage and Weeding
Intertillage and weeding are also very important for the growth of Angelica dahurica. As just mentioned, Angelica dahurica seedlings grow slowly and have weak vigor, so if weeds are not removed in time, the weeds will snatch the nutrients needed for seedling growth and seriously affect seedling growth. Intertillage can not only effectively remove weeds, but also prevent soil compaction, which would affect the infiltration of water and fertilizer, and prevent obstruction of nutrient and water absorption by the roots. During thinning and final spacing, this can be done together with intertillage and weeding. Once Angelica dahurica seedlings grow larger and close the rows, their growth ability and nutrient absorption capacity become stronger, and weeding can then be stopped.
3. Timely Topdressing
Angelica dahurica has a relatively strong tolerance for fertilizer, but fertilizer application should be controlled in early spring. If the soil is fertile, fertilization may not be necessary. This prevents excessive vegetative growth in seedlings due to too many nutrients and prevents early bolting. After spring, the growth ability of Angelica dahurica increases, and at this time timely topdressing is needed, applying once after each thinning and intertillage. Then apply once after final spacing and once before row closure. When topdressing, pay attention to the weather and do not do it on rainy days, to prevent rainwater from washing away the fertilizer and causing it to lose effectiveness. When topdressing, pay attention to the frequency and amount, specifically according to soil fertility and plant growth.
4. Reasonable Watering
Angelica dahurica has a relatively high demand for water. After sowing, the soil should be kept moist. If there is no rain, water about once every 5 days. This can improve the emergence rate. During the seedling stage, the soil should also be kept moist to prevent adverse phenomena such as yellow leaves caused by lack of water in the seedlings. Then, before winter arrives, water thoroughly with antifreeze water to improve the cold resistance of the seedlings and prevent frost damage. In the second spring, water appropriately together with topdressing, and during the dog days of summer, even more attention should be paid to ensuring sufficient water. However, the amount should also be controlled and not excessive, to prevent waterlogging of the Angelica dahurica roots caused by accumulated water, which can lead to root rot and similar problems. Therefore, we should also pay attention to drainage work.
The above is a brief introduction to the key field management points for Angelica dahurica. The management of Angelica dahurica is very important for its growth. The quality of management is directly related to the growth ability, yield and quality of Angelica dahurica. Therefore, everyone must do a good job of field management when planting.
