The basic principles are from near and far, as far as possible to lead the species in a similar ecological environment. Introducing seedlings: Generally it is better to start the spring growth period and keep the air and soil moist during transportation. Introducing rhizomes: Time is best for autumn. After the stems and leaves on the ground are wilted, the earth is dug before it is frozen; in the spring, it is excavated before emergence. Rhizome length should be more than two clusters of buds, the thickness of 7 ~ 10 mm is appropriate, an erect bud should have more than 10 mm root. The erect buds must be well protected. This is the key to introducing cultivation success. Colonization Site preparation fertilization: deep pine in the autumn, combined with soil preparation in the spring, Mushi 2000 kg of pure chicken manure and then do the bed. Floor bed, underground bed, flat bed can be, bed width 1 to 2 meters, 20 centimeters long and 15 to 20 meters to stay 50 centimeters between beds. Planting rhizomes: Plant a 15 cm wide, 15 cm deep planting trench at a 25 cm spacing and place the root section at a 5 cm pitch, then cover the soil 10 cm, and pour the water. After the water sinks down, cover the soil 5 cm. Flatten it with a rake. Transplanting seedlings: When the seedlings are 10 to 12 cm tall, they are transplanted with pods. When transplanting, plant a hole with a diameter of 20 cm and a depth of 15 cm. Place the planting hole at a density of 10 plants per square meter. Each row is 30 centimeters long. Then fill 12 centimeters around the seedlings with soil. Immediately pour water once and seep through the water. After the cover soil. Harvesting Bracken can be harvested for 15 to 20 years at a time and harvested from May to June each year. When the seedling height 25 to 40 cm, young petiole, lobular has not yet started, it should be harvested. 10 to 15 days after the harvest for the second time, can be harvested 2 to 3 times a year. Be careful not to collect all the pieces. Only 2/3~3/4 can be harvested at a time. Field management After the first year of planting, the task of field management is to catch seedlings to achieve Miao Qi and Miao Zhuang. The soil moisture must be guaranteed at 55% to 60%. After the water is poured, the leaves or straw can be covered. The dry grass is protected from light and moisture. During the growth and development period, more ploughing and weedy grasses can be used to keep some of the better growing grasses as shades of ferns, pouring them with water once per day during freezing, i.e., irrigating winter water; the second year's task is to cultivate the roots and make the roots stout. Multiple shoots, when the soil layer is melted 6 cm, ditch in the middle of the row spacing, 8 to 10 cm in depth, 2000 kg of chicken manure in Mushi or 1000 kg of grass ash, combined with earth cover, poured once, other management in the same year In the third year after the earth is thawed, loosen the earth's surface with rice dumplings, not too deep, generally about 3 cm, 2000 kg of chicken manure on the surface of the Mushi, pour water once, the other management is the same as the previous year; Management after the same year as the third year Bosgoo(China)Tecgnology Co., Ltd , http://www.laohuang.com
