Cultivation techniques of artificial direct seeding licorice
cultivation techniques
Selection of licorice is a deep-rooted plants, should be selected flat, fertile loose sand or loam planting. The previous crop is best with@#@245 @#@, corn and melon and vegetable fields, and it is forbidden to continue cropping with sugar beet and sunflower.
Soil preparation and fertilization: turning the selected land more than 26 cm deep, applying fully decomposed organic fertilizer 2000 kg to 3000 kg and diammonium 18 kg to 20 kg per mu, and then harrowing and leveling the land. Ridge width 20 cm to 30 cm, height 20 cm, ridge width 2 m to 2.5 m, ridge length depends on the terrain.
Seed treatment In order to prevent seedling blight of Radix Glycyrrhizae, 50% Dixone WP was added to 0.2% to 0.4% of the seed weight before sowing, and 3% of the seed weight was added to wet mix. After dressing, the seed was sealed for 6 hours to 8 hours for sowing.
sowing
Determination of sowing time licorice is a thermophilic crop, the most suitable germination temperature is 24℃ to 35℃, when the surface temperature is stable at 10℃, the best sowing time.
Sowing method adopts artificial drilling, on the whole ridge surface, according to the row spacing of 20 cm to 25 cm, the seeds are sown in the ditch, the soil depth is about 2 cm, and the dry weather after sowing should be watered in time to keep moisture. Under suitable temperature and humidity conditions, seedlings can emerge 7 to 18 days after sowing.
The sowing rate per mu is 1.5 kg to 2.5 kg, and the number of seedlings per mu is 20,000 to 25,000.
field management
Weeding licorice field should be weeded early, grass should be removed, artificial weeding should be done once or twice before licorice seedling setting, no weeds should be kept in the field, artificial weeding should be given priority to small area planting, large area planting, and special herbicide for licorice field can be used to control weeds.
When the seedling height is 8 cm to 15 cm, the seedling is fixed according to the plant spacing of 6 cm to 8 cm, and small, weak and sick seedlings are removed.
After top dressing and seedling fixing, apply seedling fertilizer once, apply potassium dihydrogen phosphate 50 - 100 g per mu, add urea 100 - 150 g for foliar spraying, or sprinkle 5 - 8 kg urea between rows and then water; apply fertilizer for the second time, when the growth of the aboveground part weakens, the underground root grows quickly at this time, apply diammonium 6 - 8 kg per mu, or potassium dihydrogen phosphate 100 - 150 g per mu, add spray treasure 1 foliar spraying.
After watering seedlings should be appropriate "squatting seedlings", the first water must be set after the seedlings, irrigation depends on moisture content later. The licorice formed in the same year is watered for 3 to 5 times in the whole growth period.
harvesting and processing
Digging in the middle of October, the whole growth period is about 150 days. Artificial digging depth of 45 cm to 50 cm, try to dig out the whole root, will dig out the whole root to remove the ground part and soil, can be sold after drying. Such as large-area planting with licorice special plow harvest, manual pick out. The dried licorice can be further processed. The method is: remove the hair root tail, pick up the licorice strip, cut into oblique pieces about 3 cm to 4 cm long; the hair root tail can be tied into a handle for sale.

Mushroom fresh-keeping is better in fine-pore packaging.
After comparing several different packaging forms of mushrooms, a British horticultural researcher found that mushrooms packed in shallow trays and packed with thin porous film (which allows oxygen and other gases to pass through) have a longer shelf life. A small range of "micropores" a few centimeters square on the film can provide just the right amount of oxygen for mushrooms to breathe without oxidizing phenols. This kind of film can also make the water permeate without drying up the mushrooms. It is said that the mushrooms packed with this film keep the mushrooms white and hold the mushroom head tightly than those packed with perforated film and trays.

Treated with traditional Chinese medicine such as mung bean and licorice, the cure rate is more than 95%. Dosage and usage: mung bean 1000 grams, licorice 300g, add water appropriate amount of water frying, warm irrigation. The above is the dosage of big pigs, the consumption of small pigs, 2 times a day, 2 to 4 times will be cured. Can also be used sesame oil 150 to 200 ml once perfusion, the above is the dosage of big pigs, pig reduction, serious illness, repeated irrigation 1 time, generally in half an hour later can be effective.
