How to plant trichosanthin

Radix Trichosanthis is one of the most commonly used traditional Chinese medicine in China, and its root system can be used as medicine. It has the effects of clearing heat and purging fire, invigorating body and relieving thirst, expelling abscess and detumescence, and is the main raw material of proprietary Chinese medicine for the treatment of diabetes, so there is a growing demand for it in the market. artificial planting develops very fast, and the planting method of Trichosanthes is introduced below.

1. Land selection and preparation

Trichosanthes likes warm, moist, ventilated, transparent environment, afraid of waterlogging and drought, not cold-resistant, and requires deep, loose and fertile soil when planting. When planting, we should select the land that meets the conditions, after selecting the planting land, clean up the residual plants of weeds, and then apply 2000-3000 clean farm manure and 50-80 kg compound fertilizer per mu of ploughing, rake it fine and level it, make beds and wait for planting.

2. Methods of reproduction

The reproduction methods of trichosanthin include seed propagation, root propagation and vine propagation. Seed reproduction is generally used in large-scale production. The sowing time is between Qingming Festival and Grain Rain. Soak the seeds in warm water of about 40 degrees for a day before sowing. After soaking, suck them out and hang them for sowing. The method of hole sowing was used to sow seeds on demand according to the row spacing of 12 × 20cm, 1-2 seeds in each hole, covering the soil and watering, keeping the soil moist before emergence, controlling the humidity at about 20%, and the seedlings could emerge after about 15-20 days.

3. Field management

In order to strengthen the field management after emergence, the first thing to do is to loosen the soil and weed to ensure that there are no weeds in the field affecting the growth of the seedlings. Watering keeps the soil moist and speeds up the growth of seedlings. When the seedlings grow to about 50cm, they should be fertilized twice, each time applying 10 kg of urea per mu. When fertilizing, the fertilizer should be 20-30cm out of the roots. Watering immediately after fertilization, so as to avoid excessive fertilizer causing seedling burning.

4. Diseases and insect pests

The main diseases of trichosanthin are spot blight, root rot and nematode disease. Class blight usually occurs from June to September. Bordeaux solution and mancozeb are sprayed to control the disease. The root rot disease mainly occurs in May and is more serious in the rainy season. When the disease occurs, the diseased plants should be removed in time and the disease points should be disinfected. Nodal nematode disease mainly harms the root system, and prevention should be given priority to. During planting, the soil should be ploughed for many times, combined with soil drying agents to disinfect and kill insects, strengthen field management, and increase the application of organic fertilizer. The pest is mainly grub, which is the larva of beetle, which mainly harms the root system, and can be controlled by artificial killing or insecticide control.
