Asparagus is the root of the Asparagus lily plant. Alias ​​Tiandong, tomorrow winter, Xiaoye Qing and so on. Sweet and bitter, cold, there is nourishing yin and heat, lungs and fluid effect. The main production of Guizhou, Sichuan, Guangxi and other places.
1. Site selection and site preparation: In areas below 1,000 meters above sea level, it is best to choose sparse mixed forests or under broad-leaved forests. It can also be planted between farmland and corn, broad bean and other crops, and where there is not much sunlight between the two mountains. Select the soil according to its growth and deepen it by 30 cm to remove weeds and branches. 250,000-3000 kg per acre of cooked manure, 100 kg of cake fat, 50 kg of superphosphate, after the leveling, a width of 150 cm high and 20 cm in height.
2. Breeding methods: There are two kinds of seed propagation and branch propagation.
Dichotomy propagation: When digging the asparagus, the strong mother plants with large roots and stout buds are selected and each plant is divided into at least 3 clusters with 2-5 buds per cluster with 3 or more small roots. The incision should be small, and lime should be applied to prevent infection. Planting can be carried out after a day of airing, with a spacing of 2,450 cm.
3, field management
(1) For cultivating and weeding, it is necessary to rush the grass and loosen the soil for 4-5 times during the growth period. Each time the loose soil should not be too deep to avoid hurting the roots.
(2) scaffolding, when the stalk grows to about 50 centimeters, it is necessary to set up brackets or pillars, so that the vines winding growth for the growth of stems and leaves and field management.
(3) Dressing: Each year before thawing, 2500-3000 kg of stubble is applied per acre, and the soil is mixed with four teeth to uniformly mix the excrement. In the late June or early July, one-time or one-mu. Apply 10 kg of compound fertilizer to cover soil and water.
4. Pest control
It is mainly spider mites, and leaves are infested from May to June. Prevention methods: (1) Clearing the garden in winter, deep-lying or burning dead litter; (2) Spraying 0.1-0.3 Baume degree lime sulfur spray, once a week for 2-3 times.
5, harvest processing
Harvesting: From November to early spring in the following year, the vine was cut at a height of about 7 cm from the ground. The whole plant was excavated, and the roots with a diameter of more than 3 cm were used as medicine, leaving the mother root and small roots for species use. Production areas are generally planted for 2-3 years. The lower the number of years, the lower the root-drying rate and the lower the yield. According to the experiment, the root yield of planting 4 years compared to planting for 3 years will more than double, so it is advisable to plant the harvest for 4 years.
Processing: Wash the sediments in the roots, cook in a boiling water pot for about 12 minutes, peel off the inner and outer layers of skin with a knife or hand, wash the outer layer of glue with water, and dry it until it reaches 80%. Smoke with sulfur for 10 hours, then bake or dry to dryness. To prevent discoloration, apply to a white paper cover. Planting 450-500 kilograms of dry goods per acre for 3 years, with clean, light yellow, thick and thick, translucent is excellent.
