Key Field Management Techniques for Dendrobium Planting
Dendrobium is a very popular traditional Chinese medicinal herb in our country. The main medicinal part of Dendrobium is the stem, which has the effects of nourishing yin and the stomach, and clearing heat and promoting body fluid production. The area of Dendrobium cultivation in our country is also very extensive. Dendrobium has relatively strong growth ability and is relatively easy to grow, but we still need to do a good job in field management during cultivation 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 cultivation, the soil must always be kept moist to meet the water 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 moisture is sufficient and there is a lot of rain, the amount of watering can be reduced. Otherwise, water in a timely manner. The amount of water should not be too much, to prevent water accumulation from rotting the roots and causing the death of Dendrobium.
2. Intertillage and weeding
Intertillage and weeding is an essential management task when planting Dendrobium, because Dendrobium plants are not tall and their nutrient absorption capacity is not strong. Especially during the seedling stage, if weeds are not removed in time, the growth ability of weeds is far higher than that of Dendrobium. They will snatch the nutrients needed for Dendrobium growth and shade the seedlings, blocking light reception and inhibiting the growth of Dendrobium. Therefore, during cultivation, weeding must be done well so that nutrients are concentrated 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. The fertilizer is mainly decomposed farmyard manure, with an appropriate amount of nitrogen fertilizer and trace elements added. Control the ratio 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 plant's cold resistance and heat preservation ability, 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 pruned to promote new buds from the stems and improve permeability. If it is on seed trees, then the branches should also be pruned to prevent excessive closure and lack of light from affecting the growth of Dendrobium.
5. Pest and disease control
Common pests and diseases of Dendrobium include leaf spot disease. Leaf spot disease generally has a high incidence rate in late spring. After leaf spot disease occurs, dark spots will appear on the leaves of Dendrobium, and the edges of the spots will change. Then they will gradually expand and extend, eventually causing the leaves to wither, yellow, and fall off, seriously hindering the growth of Dendrobium and reducing yield. Therefore, we must do a good job in weeding, clearing the garden in winter, regular disinfection, and then frequently observe the growth status of Dendrobium, so as to detect diseases early and treat them early. When necessary, use agents such as carbendazim for control.
The above is a brief introduction to the field management techniques for Dendrobium. 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.
