The Latest Planting Techniques and Methods Tutorial for Qingtian Kui (Nervilia fordii)
Qingtian Kui (Nervilia fordii) is a perennial herbaceous plant with fleshy roots in the Orchidaceae family. It is one of the well-known Chinese medicinal materials in our country. Its whole plant can be used as medicine and has the effects of clearing heat and detoxifying, dispersing scrofula and resolving nodules, and relieving cough and clearing the lungs. Qingtian Kui has always been relatively scarce and is a traditional export medicinal material with extremely high economic benefits. Because wild resources are becoming fewer and fewer, artificial introduction and cultivation have already begun in some areas of our country. Now, follow the editor to take a look at the planting techniques for Qingtian Kui.
1. Site Selection and Land Preparation
Qingtian Kui prefers shady and humid environments, so choosing understory land for cultivation is most suitable. For the soil, red loam rich in humus is best, and clay soil is not suitable for planting. Because the root system of Qingtian Kui is relatively shallow, the soil should not be plowed too deeply during land preparation, so as not to affect root growth; 15-20 cm is appropriate. Its growth cycle is relatively short, so base fertilizer should be applied during plowing, with 2000-3000 kg of decomposed farmyard manure per mu. After raking fine and leveling, make high beds.
2. Propagation Methods
The seeds of Qingtian Kui have weak germination ability, so seed propagation is rarely used in production. Generally, corms are used for propagation, and the so-called seeds in planting usually also refer to its corms. Around Qingming, before the corms sprout, dig them out, grade them according to their size, and dry them in a ventilated place for 1-2 days. Choose a sunny day for sowing and use the method of hole sowing. On the bed surface, open holes at a spacing of 12×18 cm or 15×20 cm, plant one plant per hole, with a sowing rate of 8000-10000 plants per mu. After planting, cover with soil, then cover the bed surface with a layer of rice straw or fallen leaves to keep warm and moist, so as to facilitate seedling emergence.
3. Field Management
Qingtian Kui has shallow roots, so after seedlings emerge, generally no intertillage is needed; only weeding is required, and manual pulling of weeds is recommended. May to June is the peak growing season for Qingtian Kui. At this time, fertilizer and water management should be strengthened. Apply clear manure water 1-2 times, about 150-200 kg per mu each time, and also supplement with 5 kg of compound fertilizer to promote rapid plant growth. Qingtian Kui likes humid environments, so the soil should often be kept moist. During the rainy season, drain water in time to avoid root rot. After the plant bolts and flowers, in order to concentrate nutrients in the corms and leaves and increase yield, remove the flower stems in time.
4. Pest and Disease Control
The main disease of Qingtian Kui is leaf spot, which mainly damages the leaves and has a great impact on yield. When the disease occurs, spray carbendazim solution for control, once every 7-10 days, for 2-3 consecutive times. The main pest is slugs, which also damage the leaves. Spraying Mesurol or methaldehyde for control has a relatively good effect.
