Rohango is a thempon crop with a base fertilizer: 8-10 kg of decomposed manure or americium or potassium sulphate compound fertiliser of 50-100 g and phosphorus fertilizer of 100-150 g before cultivation. Cultivation is carried out in a rational manner, with approximately 120 plants per acre, with early spring temperatures above 15°c and cold areas in the north after the festival. The first 15 days of cultivation were long, wide and 30-50 cm deep, choosing warm morning afternoons. Rohango, a male and female plant, needs to be planted with a sapling seedling, which is usually done before the seedlings are produced, and a grouping of seedlings takes place as long as 0. 5 metres, depending on the person concerned, so that it can be cultivated under the sheds. The number of orchards with male varieties is below 1 to 2 per cent for conventional potato varieties and 2 to 3 per cent for group seedlings. Orchards where conventional seedlings are grown at temperatures above 15°c will produce new seedlings, which, if climate is appropriate, will soon grow into seedlings. When the seedling grows up to 15-20 cm, it is to seed, to choose one of the strongest chickens to be the result of the master chicken, and to remove the rest. If the temperature is below 15°c, the temperature is very different and the light is insufficient, the disease must be protected against sudden onset. When the seedling grows up to 20-30 cm, a piece of bamboo (tree) is placed around 2 m by the seedling in order to bind the seedling into a shed. When the temperature rises at 15°c in the early spring, the base rises with three or five new lines
At 10-15 centimetres, the strongest one was chosen for the female, and the rest was razed in time. The female chicken is 30 cm or more tall and is placed in a bamboo branch, which leads the part of the chicken to the garb. All the buds on the shen under the roof were removed in time for her strong growth. The selection of the main chicken, the development of a healthy skeleton, and when the mother goes up to the shed, it is appropriate to take her heart off in a timely manner, so that the four or five strong chickens will be divided, the length of 10 or 15 knots on both sides will be lengthened, and the extraction of two or four chickens from the first. And then, at 15-20 knots, the graft caused the regeneration of two or three double chickens, all of which were reasonably evenly spread over the shelf and formed a physical skeletal frame. Care should be taken during the nursery period to be guided by the principle of diligence, which is dominated by rotting human urine and pig and cow dung, and by biogas water as a means of fattening. First pursuit of fertilizer: after five to seven days of plant-planting, thin fertilizers are applied to promote plant growth, usually once a week, when a small seedling grows to about 20 cm. It will be repeated 10-15 days thereafter. During the rainy season, attention should be paid to drainage, especially in orchards planted using dry fields or flat fields. Water should be watered when the weather is dry. Rohango is a female and male plant, and long beach, lajiang and green fruit are produced by artificial pollination (showing). At 5-7 a. M., a well-developed male is chosen to be released or microploughed and to be placed in the shade. When the female is open, the pollen is picked up with bamboo sticks. Then the female column is softly painted, and a male can pollute 10-12 females。
