The latest course on planting techniques and methods of Cnidium monnieri

Fructus Cnidii, also known as wild fennel, cnidium seed, and so on, is a perennial herb of Umbelliferae. It is distributed in most parts of China and is often born on hillsides, grasslands, roadsides, bushes and under forests. It has the functions of warming kidney, strengthening yang, dryness and dampness, dispelling wind and killing insects, and has high cultivation value. Let's take a look at the planting techniques of Cnidium.

Soil preparation and fertilization

Cnidium monnieri has strong adaptability, likes cool and humid environment, likes water and fertilizer, and has lax requirements on the soil. It can be cultivated in general soil, but it is better to have a thick soil layer and loose and fat loam. Select fields with flat terrain, loose and fertile, rich in organic matter, and cultivate them carefully. Combined with soil preparation, apply sufficient basic fertilizer, 3000 kg of soil miscellaneous fertilizer, 20 kg of urea and 50 kg of phosphorus and potassium fertilizer per mu. Then make beds, dredge drains, and wait for sowing.

Sowing method

Cnidium monnieri is propagated by seeds, sowing in autumn and spring, from September to October, and in spring before and after the Qingming Festival. Soak the seeds in water for 12 hours before sowing, mix them well with 2 times the volume of wet sand, and then sow them 2-3 days later. Pay attention to stirring during the treatment, keep the temperature and humidity consistent, and there is no need to treat the seeds for winter sowing. When sowing, first use the rake to open a shallow ditch on the finished border surface, spread the seeds evenly into the ditch, and then turn it over with a rake to flatten it twice, so that the soil cover has no seeds, and the drips are watered to facilitate seedling emergence. The sowing rate is 2 to 3 kilograms per mu.

Field management

Cnidium is growing very fast. After finishing the seedlings, attention should be paid to ploughing and weeding, watering immediately in dry weather, sunny and rainy weather, and timely drainage. After budding, fertilizer should be applied once, 5 kg of urea and 5 kg of potassium dihydrogen phosphate per mu. But usually in the first year, you don't need to apply chemical fertilizer to avoid lodging, you can plant it twice a year, and you don't have to sow seeds the second time.

Pest control

The main disease of Cnidium monnieri is leaf spot, which can be controlled by spraying with 40% carbendazim 500 times solution at the initial stage of the disease. Spray once a week, three times in a row. Powdery mildew can be prevented and treated with strychnine at the initial stage of the disease. The main pests are green insects biting leaves, or wrapping armyworm to eat flower buds, which can be killed with caprylic acid and pyrethrum.

Harvest and processing

The seeds of Cnidium monnieri were harvested in mid-June before and after sowing before and after the Beginning of Winter. Spring sowing was harvested in mid-July and summer sowing in mid-September. When the seeds were 90% mature, the upper seed branches were cut off, dried, threshed and cleaned with sickle. It can be sold as medicine, with a yield of 200kg per mu for those with yellow color, full grains and strong fragrance.
