Artemisia halodendron, also known as garland chrysanthemum, is a perennial wild perennial herb. The plant stands upright. Its tender stem is the main edible organ. It has strong resistance to stress, resistance to pods, strong germination power, and a special fragrance. After cultivation in this area, the area has been continuously expanded and the technology has been continuously improved. At present, we have explored the pollution-free cultivation technology of Artemisia selengensis with double membranes. First, choose good breeds. Select the large leaf green stalk Artemisia species. Stalk cuttings are commonly used, with fresh plants weighing 340-350 kg per mu. Select the thick seedlings to cut flatly, cut off the soft top part and the aging part of the base, take the middle semi-lignified stalk and cut it into small pieces of 10-25 cm long, tie it into small handles, immerse in water for 22-24 hours, and then Place in a cool and ventilated place for 7-15 days until the roots are sent out. Second, deep plowing soil preparation, fertilizer bed soil. Before planting the plots, it is necessary to deepen the cultivation of the sun, apply the base fertilizer, and plow till it is finished. The squat will be smashed, and the sill shall be 4 meters wide with a good drainage ditch around it. The basal fertilizer is mainly composed of high-quality organic fertilizer and organic compound fertilizer, combined with 500 kg of organic manure and 500 kg of organic compound fertilizer per acre. The soil is deeply ploughed into the soil so that the fertilizer and soil are fully crushed and mashed. After the leveling, 45 sprays are applied. % Garlic grass net 100 ml water 50 kg soil treatment to prevent weeds harm. Third, timely planting, reasonable planting. In early July, stalk cuttings were planted. The treated stems were planted with 30-35 cm 30-32 cm spacing, and 2-3 plants per hole were planted. After the surrounding soil is pragmatic, irrigating the water. Fourth, moisten live trees, chase and promote strong. Before you live, water the plants in the early morning to keep them moist and promote plant survival. During high temperature and drought, irrigation and drought should be applied, and drainage and timely drainage should be conducted after the flood season and heavy rain. If there are locusts, net prevention and control will be used once. From late September to early October, 50 kg of organic compound fertilizer or 10 kg of urea are applied per acre to promote the growth of roots and stems, and they are topping in time before flower bud emergence. Fifth, lay two membranes to regulate temperature and humidity. Plants can be covered with film after being frosted. Coverage time can be adjusted to the market sooner or later, staggering the harvest period and achieving a balanced market. Cover plants on the ground 10-15 days before the cover film, remove dead leaves and leaves, do not bump the ground buds, apply 15 kg of organic compound fertilizer per acre, loosen the soil, dry the soil to add water, cover before 7-10 days to stop watering, first to cover the plastic film, and then cover the film, harvest before and after the Spring Festival. After the shed film is covered, keep it at 15-30°C during the day and allow it to cool off when it exceeds 32°C. After the cover film is generally not watered, when the tender stems grow to 10-15 cm, spraying high yield spirit, promote seedling color to green. Sixth, timely harvest, graded sale. When the tender stem grows to 20-30 centimeters, it is harvested and marketed. It is cut off from the plant near the ground with a sharp file, and immediately transported to a cool place. The leaves on the plants are wiped off, and the bundles are tied up and erected to be sold. For the second harvest, we must clean up the flour surface, remove the weeds, chase the fertilizer, apply 100 kg of compound fertilizer per acre, and harvest it after 30-40 days. For the second time, the removable film can be grown in open areas for the next season.
