Detailed Explanation of the Latest Planting Methods and Techniques for Trichosanthes Root
Trichosanthes root is one of the bulk commonly used traditional Chinese medicinal materials in China, also known as Gualou root. Its root system can be used as medicine, with effects of clearing heat and purging fire, promoting fluid production and quenching thirst, draining pus and reducing swelling. It is the main raw material for Chinese patent medicines treating diabetes, so market demand for it is growing larger and larger, and artificial cultivation is developing extremely fast. Below is an introduction to the planting methods for Trichosanthes root.
1. Site Selection and Land Preparation
Trichosanthes root prefers a warm, humid, well-ventilated and well-lit environment. It is afraid of waterlogging and drought, and is not cold-tolerant. When planting, soil with deep soil layers and loose, fertile texture is required. When planting, select a plot that meets the conditions. After choosing the planting site, clean up weeds and leftover plant debris, then, in combination with plowing, apply 2000-3000 [jin] of farmyard manure and 50-80 kg of compound fertilizer per mu, rake it fine and level it, make beds, and wait for planting.
2. Propagation Methods
The propagation methods for Trichosanthes root include seed propagation, root division propagation and vine layering propagation. In large-scale production, the seed propagation method is generally used. The sowing time is chosen between Qingming and Guyu. Before sowing, soak the seeds in warm water at about 40 degrees for one day. After soaking, absorb and remove them, let them dry slightly, and wait for sowing. Sowing adopts the method of hole sowing, opening holes at a plant-to-row spacing of 12×20cm for dibbling, placing 1-2 seeds in each hole, covering with soil and watering. Keep the soil moist continuously before emergence, control humidity at about 20%, and seedlings can emerge after about 15-20 days.

After emergence, field management should be strengthened. The first thing to do is loosen the soil and remove weeds to ensure that no weeds in the field affect the growth of seedlings. After the seedlings are uniform, cultivate in time to promote root growth. Water to keep the soil moist and speed up seedling growth. When the seedlings grow to about 50cm, fertilize twice, applying 10 kg of urea per mu each time. When fertilizing, note that the fertilizer should be placed 20-30cm from the roots, and water immediately after fertilizing to avoid excessive fertilizer causing seedling burn.
4. Pests and Diseases
The main diseases of Trichosanthes root are leaf spot disease, root rot and root-knot nematode disease. Leaf spot disease generally breaks out from June to September. When it occurs, spray Bordeaux mixture and mancozeb for control. Root rot mainly breaks out in May and is more severe during the rainy season. When it occurs, remove diseased plants in time and disinfect the diseased holes. Root-knot nematode disease mainly damages the root system, so prevention should be given priority. When planting, plow the soil multiple times, combine soil solarization with chemical disinfection and insect killing, strengthen field management, and increase the application of organic fertilizer. The main insect pest is the white grub, which is the larva of the scarab beetle and mainly damages the root system. It can be controlled by manual capture or chemical insect killing.
