Latest Technical Methods and Tutorial for Field Management of Dendrobium
Dendrobium is a very popular traditional Chinese medicinal herb in our country. The main medicinal part of Dendrobium is the stem, which has the functions of nourishing yin and the stomach, and clearing heat to promote body fluid production. The area planted with Dendrobium in our country is also very extensive. Dendrobium has relatively strong growth ability and is relatively easy to plant, but when planting we still need to do a good job in field management to ensure the growth of Dendrobium. Below, the editor brings you the field management techniques for Dendrobium. Let's take a look together!
1. Reasonable watering
Dendrobium has a relatively large demand for water during its growth process. During planting, the soil must always be kept moist to meet the water requirements needed for Dendrobium growth and promote healthy growth of Dendrobium. However, when watering, we still need to water reasonably according to soil moisture conditions, weather changes, and the growth status of Dendrobium. When there is sufficient soil moisture and it is rainy, the amount of watering can be reduced. Otherwise, water in time. The amount of water should not be too much, to prevent waterlogging, root rot, and death of Dendrobium.
2. Intertillage and weeding
Intertillage and weeding is an indispensable management task when planting Dendrobium, because the Dendrobium plant is not tall and its nutrient absorption capacity is not strong. Especially at the seedling stage, if weeds are not removed in time, the growth ability of weeds is far higher than that of Dendrobium. They will seize the nutrients needed for Dendrobium growth and shade the seedlings, causing obstruction of light reception and inhibiting the growth of Dendrobium. Therefore, during planting, weeding must be done well to concentrate nutrients on Dendrobium.
3. Timely topdressing
Dendrobium has relatively large nutritional needs. Generally, topdressing needs to begin in the second year after planting, and the number of topdressings each year must not be less than two times. The fertilizer is mainly decomposed farmyard manure, with an appropriate amount of nitrogen fertilizer and trace elements added. The ratio should be controlled well to ensure that Dendrobium growth has sufficient and comprehensive nutrition. When fertilizing, apply it around the plants, spreading it around the plants to promote the growth of young buds. Then before winter, the same kind of fertilizer should also be applied to improve the cold resistance and heat preservation capacity of the plants and increase the overwintering survival rate.
4. Proper pruning
Pruning work is also very important for the growth of Dendrobium. During the growth process, excessive pruning is not necessary. Generally, at the time of annual harvest, the old branches, dead branches, weak-growing branches, pest- and disease-affected branches, and overly long and dense stems on the plants should be removed to promote the stems to sprout new buds and improve air permeability. If it is on seed trees, then the branches should also be pruned to prevent them from being too closed, which would block light and affect Dendrobium growth.
5. Pest and disease control
The common pest and disease problem of Dendrobium is leaf spot disease. Leaf spot disease generally has a high incidence rate in late spring. After the onset of leaf spot disease, dark spots will appear on Dendrobium leaves, and the edges of the spots will change. Then they will gradually expand and extend, eventually causing the leaves to turn yellow and fall off, seriously hindering the growth of Dendrobium and reducing yield. Therefore, we must do a good job in weeding, clear the garden in winter, disinfect regularly, and then frequently observe the growth of Dendrobium to achieve early detection and early treatment of diseases. When necessary, use agents such as carbendazim for control.
The above is a brief introduction to the field management techniques for Dendrobium. The field management of Dendrobium is relatively simple. Only by doing these management tasks well can we ensure the healthy growth of Dendrobium and increase yield. That is all for today's introduction. This article is for reference only.
