Land selection and preparation
When planting Huang Jing, you need to choose a moist, shaded, well-drained plot with deep and fertile soil, loose soil, and easy watering, and avoid continuous crop. The plots planted with yellow essence and seedlings in the previous crop cannot be used as seedling fields. In the selected plot tilled 25-30 cm, leveled and harrowed; open the drainage ditch, ditch width 30 cm; make a raised bed 1.5 m wide and 20 cm deep, the border is leveled and compacted. Apply 1000 kg of well-rotted farmyard manure or 50 kg of commercial organic fertilizer and 25 kg of compound fertilizer per mu.
Transplanting method
Plant as soon as possible after obtaining seeds, the earlier the better, from September to mid-March of the following year (transplanting should be done after the seedlings have fallen and before they emerge). Plant the seeds in a trench at a spacing of 25 cm x 17 cm, with a depth of 10 cm. Soak the seeds in a solution of carbendazim 800 times and rooting powder for 10 minutes or mix them with quicklime powder, dry them slightly, place them in the trench, and cover them with 5-8 cm of soil. After transplanting, 1 time of rooting water is required.
Field management
Mulching
After planting Huang Jing seeds, they should be covered with a layer of straw or leaves, hay, or other mulch, which can retain moisture on the one hand and keep warm on the other, so that they can take root before germination.
Weeding and loosening the soil
After the seedlings emerge, the soil should be loosened and weeded in time to keep the border free of weeds. Weeding is usually done during the seedling stage (5-10 cm high) and the pre-blooming stage (mid to late April), and three times in the first year of planting, but after two years, there is no need to weed, only to pull out the weeds that grow vigorously.
Additional fertilizer
If the base fertilizer is sufficient, fertilizer cannot be pursued in general. If there is no fertilizer or little fertilizer, fertilizer can be combined with mid-tillage and weeding. The first time in the emergence of yellow sperm (mid-March) with irrigation fertilizer, and the second time in early May to promote flowering fertilizer.
Irrigation and drainage
In the May flowering period, Huangjing needs more water, if dry early, soil moisture is poor, should be timely in the border ditch put water infiltration or sprinkler irrigation, and prohibit large water diffusion. 8-October is Huang Jing underground part of the rapid growth period, if encounters continuous rainy weather and soil waterlogging, should be timely drainage.
Topping control
Topping is done at the time of leaf development when yellow sperm leaves are at 8-10 nodes. Select a sunny day 06:00-10:00, by hand pinching method to remove the top bud.
Harvesting and processing
If Huang Jing is harvested too early, the yield is not yet formed; if it is harvested too late, the density is too high and the competition for nutrients is intense, which affects the growth of Huang Jing.
Huangjing propagated by seeds can be harvested in 3-4 years, and Huangjing propagated asexually can be harvested in 1-2 years. It can be harvested in autumn after the above-ground part withered to the next spring before germination. The harvested yellow essence is washed to remove the roots and stems, washed the soil, removed the rotten scars, steamed through, dried in the sun, or dried.
