With the rise of agriculture and tourism picking agriculture in the various regions of the park, the demand for characteristic potato varieties has gradually increased. The black potato is a new colored potato variety that combines nutrition, health care and appreciation. Except for the exquisite, fragrant and savory quality , There is also a unique bright color appearance, with cancer prevention, beauty and other effects. The cultivation area of ​​black potatoes in the country is still small, the price per kilogram is about 10 yuan, which is 6-8 times that of ordinary potatoes. Black potato cultivation points are as follows: germination and cutting. 20-30 days before sowing, the selected seed potatoes will be placed evenly under 20°C ambient conditions, sprayed with water and covered with grasshoppers. When the young shoots grow to the size of the soybeans, the seed potatoes will be placed in a warm and sunny place and the seedlings will be green and vigorous. Seed cuttings are made 1-2 days before sowing. The weight of each seed potato is about 25 grams. A small piece of seed potato is cut vertically, and each cut must have a top bud; the large seed potato is cut open from the tail, and the weak shoots are eliminated. The buds are arranged in order, cut obliquely from the top, and finally the top is divided into two. The knife must be strictly disinfected with 75% alcohol. Soil preparation. The black potato has a short growing period and requires more concentrated fertilizer. It spreads 3-5 cubic meters of organic fertilizer per acre, 20 kg of diammonium phosphate, 20 kg of urea, and 10 kg of potassium sulfate. After fertilization, the soil is deeply ploughed. Planting black potatoes should not be suitable for dense planting. Grooves should be 70 cm apart and the ditch should be 5 cm deep. When grooving, phoxim granules should be applied to control underground pests such as ground tigers. Seedlings were planted at a plant spacing of 25-30 cm. About 3,500 plants were maintained per acre. Immediately after sowing, the ridges were repressed and well-formed, and the mulching film was sprayed with the herbicide. Field management. After the seedlings are unearthed, the seedlings shall be broken and the seedlings shall be sealed with the wet soil. When the seedlings are aligned, in order to promote the early emergence of seedlings, foliar spray can be applied to the leaves; in the flowering period, the buds are removed timely. To increase the rate of large potatoes, foliar spray can be applied to the ground. The main disease of black potatoes is late blight, insects are aphids and ladybugs. The prevention of late blight can be sprayed with 64% antivirus 600 times liquid + new high-fat film; the control of aphids and ladybugs can be sprayed with 18% Lethburn 1000 times liquid + new high fat film. Timely harvest. Harvesting at a timely manner, to minimize mechanical damage during harvesting, so as not to affect the quality of goods.
