The green pollution-free high-quality potato cultivation technology is a cultivation technology based on traditional potato cultivation techniques by applying more organic fertilizer, less application of chemical fertilizer, selection of varieties with strong disease resistance and high quality, and using physical means for insecticidal sterilization. . The specific points are as follows: 1. Timely deepening sun soil, insecticidal sterilization. After the harvest of summer crops such as peas and wheat, deep-rooting the soil in a timely manner and using the characteristics of high sunlight intensity in 3 volts, the sun will kill the earthworms and other underground pests, killing the low-temperature resistant bacteria in the soil and providing a safer potato growth for the following year. Soil environment. 2. Increase organic fertilizers to increase fertilizer utilization. The large amount of fertilizer such as ammonium bicarbonate is the main factor that causes potato rot, affects potato quality and commodity rate, and it is easy to cause soil compaction. Applying more organic fertilizer can not only improve the soil, but also improve the quality of the potato. General Mushi ash 6,000 kg, 5,000 tons of manure urine faeces. When the organic fertilizer is stored, the method of storage of grass ash and human urine excrement separately is adopted so as to avoid the loss of nutrients due to the mixing. With organic fertilizer, Mushi phosphate fertilizer 10 kg, urea 5 kg. The combination of fertilization and sowing is carried out. Generally, organic fertilizer is applied to seed potatoes and chemical fertilizers are applied to empty rows. 3. Use high quality seed potatoes. Excellent varieties are not only the precondition for the stable production and high yield of potatoes, but also the main factor for ensuring the quality of potatoes and the resistance to diseases and insect pests. Starch-processing potatoes generally use sweet potato No. 2, Ningshu No. 8, Alpha, and Yushu No. 3 Other varieties, late-maturing export-oriented general selection of resistant storage of sweet potato 68, Ningshu 4 and other varieties. 4. Promote the sowing of small whole potatoes and the strict disinfection of the cutters. Small whole potatoes have the characteristics of strong vitality, strong drought resistance, easy to germinate, robust seedlings, avoiding cross-infection of pathogens, etc. Production should be promoted to use small sweet potatoes as seed potatoes. The actual number of small and medium whole potatoes is small, and they cannot meet the seed quantity. When cutting potatoes, multiple cutting knives should be prepared and the cutting knife should be sterilized with boiling water or potassium permanganate or alcohol. When the cutting knife cuts the diseased potatoes, it should be cut immediately. Re-sterilize the knife to prevent infection by the knife. 5. Reasonably choose the planting mode and scientifically determine planting density. Choosing suitable planting methods to determine the appropriate density is not only conducive to field management, ventilation, light transmission, and reduction of pathogenic bacteria infection, but also stable yield increase. Through years of field trials, the "double-row lean" model has simple field management and significant yield increase. The suitable planting density ranges from 3,800 to 4,500. 6. Artificial field weeding, cultivator soil. After the potato seedlings are aligned, artificial cultivation and weeding are used to increase the temperature of the ground, avoid food and weed fighting for water, compete for fertilizers, and improve their resistance to drought and cold. Potatoes are cultivated before budding, combined with cultivating 3,000 tons of human manure urine organic fertilizer and 5 kilograms of urea. 7. Control potato pests and diseases. Potato pests and diseases are mainly diseases. There are mainly ring rot, late blight, black shank, and virus diseases. Ring rot mainly spreads through diseased seed potatoes. Disinfection with a knife is one of the ways to eliminate infection. Adopt comprehensive measures combining the use of disease-resistant varieties, the removal of diseased plants in the field and the selection of low-toxicity pesticides. In addition, the diseased plants were excavated at the seedling stage and the adult plant stage and treated in a concentrated manner. Late blight prevention and control is the selection of disease-resistant varieties, such as Ningshu 4 and Qingtao 168, etc.; second, disease-free seed potato; third, 64% antivirus, 400 times liquid, 50 kg per mu, once a week, Spray 3 times. Black cockroach control is the selection of disease-resistant varieties; the second is the use of small whole-plant sowing and cutting knife disinfection; the third is dressing with plant ash, the fourth is appropriate early sowing, the fifth is to remove diseased plants, virus disease prevention and promotion is to promote Toxic species, such as detoxification Alpha, the center 24, etc., and the second is the prevention and treatment of diseases, locusts with 40% of the omethoate 1000 times to 2000 times the liquid spray. Virus disease early stage, with 1.5% Bleeding Emulsion 1000 times, 20% of the virus A wettable powder 500 times spray. 8. Promote the dressing of plant ash. Seed dressing after planting with plant ash, with potassium, drought, cold, pests.
