Cultivation and Management of Artemisia selengensis
First, the selection of soil preparation Artemisia halodendron cultivation with sandy loam is appropriate, requires convenient irrigation conditions, first select the land after the turn, and into the fine farmyard fertilizer, each 0.1 hectare applied more than 1,000 kilograms, 25 kg of diammonium phosphate as a base fertilizer. Made of 1.2-1.4 meters wide, 10-20 meters long flat, ready to sow. Second, sowing and seedlings (1) seed treatment: 3-4 days before sowing, the seeds soaked with hot water 50 °C -55 °C for 15 minutes, then soaked with water for 12-24 hours, placed at about 25 °C Warm place for germination, change the water once a day during germination. If the new seeds are treated at a low temperature of 0°C-5°C in advance, dormancy will be broken in about 7 days. (2) Seeding selection: Spring planting in the protected area generally uses seedbed nursery in late March or April: spring open field cultivation, sowing seedlings in the mid-April; spring live direct cultivation, in the early May buckle small shed or mulch sowing , Summer, autumn cultivation, cold bed or open field can be staged in batches, 7-10 days a sowing period. (3) Seeding method: Visual cultivation method (live or nursery transplant) adopts sowing cultivation or drill sowing. The sowing quantity per hectare is 60-70 kilograms, the seeding is sown at a spacing of about 10 centimeters, and the amount per hectare is 30-37.5 kilograms. In early spring, nursery seedlings should be planted with medicinal soil to prevent sudden death. Nursery seedlings are suitable for 20-30 days, and 3-4 true leaves are suitable for colonization. Third, planting and field management sowing until germination emergence, generally takes 5-7 days. Pay attention to moisturizing during germination to prevent the soil from drying out. When the seedling height 2-3 cm, 1-2 true leaves when the seedlings and field seedlings, so that the spacing of 1-2 cm. And in the shallow cultivator, until the seedlings in the 3-4 true leaf stage planting, the colonization of the outside or shed temperature to be stable at 10 °C colonization, Dingzao spacing 4-6 cm. The first watering when the seedlings, Dingmiao and then watering, and with fertilizers available nitrogen fertilizer. Afterwards, the seedlings can be harvested in different stages. Fourth, the collection of Artemisia halodendron general growth period 40-50 days, when the plant up to 20 cm or so, with 12-13 true leaves can be harvested, in order to keep the product fresh, the harvest should be carried out in the morning. Harvesting is not timely, high temperatures, will lead to aging stems and leaves, poor quality, or elongation between nodes, bolting flowering. If you want to harvest multiple times, you can use a knife to cut 2-3 cm at the base of the main stem, cut the tender stems and leaves bundled into 0.5 kg to market. Watering after cutting can be harvested again after one month. NINGBO AUTRENDS INTERNATIONAL TRADE CO., LTD , https://www.metests.com
