By wearing mountain dragons, they are used to wear dragons, wear keels, and ground keels. They are perennial herb medicinal plants of the Dioscoreaceae and use rhizomes as medicine. With blood Shujin, Qufeng pain, cough and asthma and other effects. The supply gap between domestic and foreign markets is very large, artificial cultivation of Chuanshan has higher economic benefits. 1 The selection and preparation of soil dressings should be done in a loose, fertile, humus-rich forest loam or cultivated sandy loam soil. The pH of the soil should be slightly acidic to neutral, and the soil should be selected for low soil moisture and poor drainage. The best place for autumn is to prepare 60 t of farmyard manure per hectare before the site preparation, deep-deep 25-30 cm, leveling, thinning, width 1.2m, height 15-20cm, and the length is not limited. 2 seedling sowing a. seed treatment more than 1 month before sowing, the seeds were treated with sand. Soak the seed in cold water for 48 hours, remove and drain the water, and mix well with 3 times the amount of wet sand. The humidity of the sand should be hand-held and loosely spread. The uniform seeds are put into the air-permeable bag, and the seed is placed on the ground at the backside of the high-drying place, the seeds are buried with soil, the cover soil is 10 to 15 cm, and the seeds are taken out about 10 days before sowing to be sown. b. sowing method 1 sowing method: from late April to early May, sow the seeds evenly. In order to make the seed evenly, the sand mixed with the seeds should be sowed together with the seeds. After the sowing, the cover soil should be 1 to 2 cm. Gently suppress the wooden board, cover the straw 1 ~ 2cm, in order to facilitate shade moisturizing. 2 sowing method: The ditch on the ditch, spacing 15cm, ditch depth 2 ~ 3cm. Spread the seeds evenly into the ditch, cover the soil 1 ~ 2cm, cover straw 1 ~ 2cm, to shade moisture. For the above two sowing methods, the hectare sowing rate is 37.5kg. 3 Field management a. The seedlings and young seedlings will grow to about 10cm long after unearthed. When 3 to 4 true leaves are grown, the dense seedlings and germs should be removed and the strong seedlings should be kept. The plant spacing is 5cm. b. Transplanted seedlings were grown one year later, transplanted after the plants withered on the ground in the autumn, or transplanted after the second year of spring, and were planted with a row spacing of 40cm and a spacing of 20cm between the plants, and compacted after covering the soil 5cm. c. Weeding and weeding should be done for the nursery field and the weeds should be kept without weeds. Transplanting weeds in the fields should be promptly eradicated, and acetochlor can also be used to close the grass and avoid grass shortages. d. Stretching and transplanting plants should spread and spread vines after transplanting, so as to prevent the plants from intertwining, resulting in poor ventilation and disease, and also affecting the photosynthesis of the plants. e. Diseases and pests control 1 Disease: When the seedlings reach the height of 15cm, they will grow on the racks. When the seedling height reaches about 1m, due to heavy rainfall, high air humidity, leaf rot occurs, and the leaves are hot, making the plants Withered gradually, prevention should be advanced. Seedlings in the growing season, every 10 ~ 15d, foliar spraying 50% carbendazim 800 times the control effect is obvious. 2 Insect pests: In the growing season, the seedlings mainly injure the insect pests such as aphids and red caterpillars, and can be sprayed with 2.5% Kung Fu EC 1000 times spray. 4 Harvesting and processing After the transplanting, the mountain dragons can be harvested after 3 years of transplanting. The underground rhizomes are all plucked and dried after 3 to 5 days of sun exposure.
