The Latest Planting Methods and Technical Key Points for Asiatic Dayflower
Asiatic dayflower, also known as bi zhuzi, dan zhuye, etc., is an annual spreading herbaceous plant, mainly distributed in the southwestern and northwestern regions of our country. The leaves of Asiatic dayflower are brightly colored, and the flowers are bright and full, and it also has various effects such as promoting water circulation and clearing heat, cooling blood and detoxifying. Its demand as a Chinese medicinal material is now relatively large. So how should Asiatic dayflower be planted? Below, the editor will bring you the planting techniques for Asiatic dayflower, let's take a look!
1. Planting plot
Asiatic dayflower has relatively strong growth ability and does not have very strict requirements for soil. It can grow in relatively dry soil, and normal growth can be maintained as long as the soil is kept slightly moist. However, its demand for light is relatively large, so the planting plot must maintain a certain amount of light; otherwise, it will have a certain impact on the growth of Asiatic dayflower. If there is insufficient light, it is easy to cause excessive vegetative growth of Asiatic dayflower. After selecting the land, in order to ensure the healthy growth of Asiatic dayflower, it is best to carry out land preparation and disinfection work, and then apply sufficient base fertilizer to improve the quality and fertility of the soil.
2. Sowing and seedling raising
The commonly used propagation method for Asiatic dayflower is mainly seed propagation, generally carried out in early spring each year. Before sowing, soak the seeds at a temperature of about 26 degrees for about 9 hours, then take them out, wrap them in a wet cloth, and place them at a temperature of about 26 degrees for about 4 days. When most of the seeds have sprouted white, they can be sown. Use the drill sowing method for sowing, control the sowing density well, dig the sowing furrows, and evenly scatter the seeds into the sowing furrows. Then cover with a layer of fine soil, press and tread firmly, and keep the soil moist. Under suitable environmental conditions, seedlings can emerge in about 7 days. After emergence, appropriately lower the temperature and humidity to prevent excessive vegetative growth of the seedlings.
3. Field management
During the seedling stage, provide scattered light for Asiatic dayflower, and after it matures, control the shade degree at about 50%. If it is kept in a shaded place for a long time, it is easy to cause excessive vegetative growth of the branches and leaves of Asiatic dayflower, resulting in thin and brittle leaves, reduced glossiness, and lighter color. However, be careful to avoid direct sunlight, which can cause leaf scorch and affect the normal growth of Asiatic dayflower. Then, during the growing period, apply topdressing about twice a month, and frequently spray water to keep the soil moist and increase air humidity. In winter, control watering and keep the temperature above 10 degrees to ensure safe overwintering. Finally, promptly prune tiller buds to facilitate the growth of new branches. The sturdy tiller branches can be used as cuttings for cutting propagation.
4. Pest and disease control
Pest and disease damage poses a very great threat to the growth of Asiatic dayflower, so we must do a good job in pest and disease control for Asiatic dayflower. Regularly disinfect the field, fertilize reasonably, appropriately increase the proportion of phosphorus and potassium fertilizers, improve the disease resistance of Asiatic dayflower, and reduce the incidence of pests and diseases. Then frequently observe the growth of Asiatic dayflower, and after discovering abnormalities, take corresponding measures according to the actual situation. Its common pests and diseases include gray mold, aphids, etc. Although the control methods for each pest and disease are relatively similar, they are also somewhat different. Do not use pesticides blindly, so as to avoid achieving the opposite effect.
The above is a brief introduction to how to plant Asiatic dayflower. The planting of Asiatic dayflower is relatively simple. However, when planting on a large scale, we will inevitably encounter some unexpected situations, so we still need to pay attention to doing a good job in management to avoid some unnecessary losses.
