For the treatment of general deficiency syndrome, ginseng can be used instead of ginseng; for severe collapse syndrome, ginseng is still appropriate. Pick, wash and dry in autumn.

Codonopsis pilosula growing environment:

Codonopsis pilosula likes cool and humid climate, cold tolerance, high temperature stagnant water, shade and sun exposure in seedling stage and light in adult stage.

The seeds can germinate when the temperature is more than 10 ℃, and the optimum temperature for germination is 18-20 ℃. The germination rate of fresh seeds can reach more than 85%, but the seed development rate is very low in the next year, even the germination rate is completely lost, so old seeds are not suitable for planting.

The semi-sloping land was selected for seedling transplanting, and the land was turned over deeply in the winter of the first year. 15000 kg of farm manure and 750kg of phosphate fertilizer were applied per hectare, and the ground was raked flat in the spring of the second year. The Spring Equinox made a tall box with 170cm wide before and after. 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.

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".

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.
