Last Updated: 2024/11/10, The traditional Chinese medicine Codonopsis pilosula is used as a root and is born on the edge of a forest or in bushes. Distributed in western Sichuan, Gansu, Shanxi, Henan, Inner Mongolia, Hebei, Shaanxi, Northeast and other places. Cultivation is available in most provinces and cities throughout the country. Taste sweet, sex is flat. First, the biological characteristics of strong cold resistance, like cool mountain areas, can be planted in mountainous areas with an elevation of 800,000m, and sandy loam soil with deep soil layer, good drainage and high humus content is better, and continuous cropping is avoided. 2. reproduction method Codonopsis pilosula adopts the method of sexual reproduction, which is divided into direct seeding and seedling transplanting.

The traditional Chinese medicine Codonopsis pilosula is used as a root and is born on the edge of a forest or in bushes. Distributed in western Sichuan, Gansu, Shanxi, Henan, Inner Mongolia, Hebei, Shaanxi, Northeast and other places. Cultivation is available in most provinces and cities throughout the country. Taste sweet, sex is flat.

First, the biological characteristics of strong cold resistance, like cool mountain areas, can be planted in mountainous areas with an elevation of 800,000m, and sandy loam soil with deep soil layer, good drainage and high humus content is better, and continuous cropping is avoided.

Second, the reproduction method Codonopsis pilosula adopts the way of sexual reproduction, which is divided into two kinds: direct seeding and seedling transplanting.

Third, the semi-sloping land is selected for seedling transplanting, and the land is turned over deeply in the winter of the first year. 15000 kg of farm manure and 750kg of phosphate fertilizer are applied per hectare, and the ground is raked flat in the spring of the second year, and the Spring Equinox is made into a tall box according to 170cm wide. Sow 45 kg seeds per hectare in fine soil strips, trench according to row spacing of 10 cm, ditch depth of 1 cm to 2 cm, evenly sow box, cover fine soil. After emergence, pulling grass and topdressing, transplanting in the second year, 6 hectares of field can be planted in each hectare seedbed. 15000 kg of farm manure and 750kg of phosphate fertilizer were applied per hectare, then the soil was leveled and raked fine, and the two-year-old strong seedlings were dug and planted before and after "Qingming Festival" or after "White Dew" in autumn. When planting seedlings, arrange the main roots of the seedlings obliquely in the ditch according to 10ml / 20cm. The Reed head is about 7cm below the soil surface. 7500 kg of barnyard manure and 300kg of phosphate fertilizer are used per hectare to cover the seedlings in the first row of the second row.

Fourth, after field management planting, weeding twice a year, spring planting in autumn and autumn planting in spring. Codonopsis pilosula is resistant to fertilizer and is mainly based on base fertilizer. 15000 kg of light dung water or 375kg of ammonium bicarbonate should be applied per hectare in the year of planting. After planting Codonopsis pilosula, choose 170 cm long small inserts or branches, staggered between the rows every 30 cm 60 cm, for Codonopsis lanceolata vines winding. In order to collect seeds, we should first plant the seeds after 2 years, and harvest and store the mature seeds before and after "the End of Heat".

Fifth, the control of red mold root rot and yellow rust by diseases and insect pests is generally serious from May to July. After the disease, the diseased plants are removed and burned and disinfected with quicklime burns. Before sowing, disinfect the soil with 30 kilograms of pentachloronitrobenzene per hectare. Spray or irrigate the root with 65% wettable Zinc 500x solution or 1 ∶ 1 ∶ 200Bordeaux solution, once every 7 days for 2 consecutive 3 times. In order to control aphids and red spiders, dimethoate 1 kg plus 200 kg water spray plants can be used. Grub, ground tiger, mole cricket, golden needle worm, can use 75% parathion EC 700 times liquid to irrigate ginseng, or use bait to kill.

Sixth, harvest can be harvested after 2-3 years of processing. "White Dew" was carried out before and after. Dig up the roots along the way without damaging, drying or drying. Kneading and baking, repeated 4 Mel 5 times quality requirements: root length 10 Mel 15 cm, section yellow and white, fragrant smell, slightly sweet taste.
