æž¸æž Department of Solanaceae perennial deciduous shrubs, about 2 meters high, branches with ribs and spines; single leaves alternate or clustered on short branches, lanceolate or rhombic, entire; purple flowers; berries, orange red, eggs Shaped or oblong. The cool, moist and fertile soil is resistant to cold, drought, and weather, but it is not tolerant of high temperatures and can grow normally in poor roads, ditches and canals. Cockroaches can be seed-breeding, ramets, layering, cutting propagation can also be the main description of the facilities cut seedlings cultivation method: 1, soil preparation for rake: combined with soil preparation Mushi fertilizer 5000 kg, three elements of compound fertilizer 100 kg or compound fertilizer 150 Kilograms, requiring more than 30 centimeters of plough depth, soil smashed, ground leveling, fertilizer dosing, and then made into a flat width of 1 meter, with the north and south poles as well. 2. Shearing: In late February, cut from the eucalyptus tree and grow one-year-old, full-grown, pest-free one-year-old twigs. Cut into 15-cm-long cuttings. The upper mouth must be flat and the lower one must be cut obliquely. Keep sand in the house and keep it at room temperature at about 5°C. 3, buckle film: In early March, the election sunny days without wind, the plastic film covered in the shed for baking, increase the temperature of the shed. 4. Management of cutting seedlings: In late March, remove the cuttings, soak them in running water for 1 day and night, then insert them in a straight line or obliquely in the shed, and ask for about 10 centimeters of soil to be inserted. Each row will be inserted in 5 rows with a spacing of 10 centimeters. 20 centimeters, inserted after pouring water. Through measures such as dismantling, covering, spreading, etc., the temperature of the greenhouse is controlled at 12°C or more, the surface is kept moist, germination is possible in about 25 days, the temperature of the greenhouse is controlled to be above 10°C after germination, and the surface is slightly damp (or relative humidity is 75%). . When the grass grows, it can be ploughed and weeded, raising the temperature. In mid-April, after a period of time when the air is forced to grow, it can go to the shed film. If it is a worm, 3000 times of the enemy can be used to prevent and control, and other managements can be used to raise the land with the land.
