Potatoes, commonly known as potatoes, are a fully-fledged food and vegetable crop. The principle of high yield and high quality potato production is: base fertilizer should be sufficient, topdressing should be grounded, nitrogen, phosphorus and potassium should be reasonable, magnesium fertilizer should not be lacked, and root application and foliar application must be combined. The specific technical points are as follows: 1. Apply basic fertilizer to base fertilizer Organic manure is dominant, and adequate organic manure is applied. That is, on the basis of applying 2500-3000 kg of organic fertilizer per acre, 45-50 kg of organic fertilizer is applied in Mushi. When digging planting holes in the site, the basal fertilizer and the soil in the planting hole can be fully mixed and planted. 2. If the fertilizer is insufficient or if the cultivated land cannot be fertilized beforehand, it is often the case that the seed fertilizer is used for 15-20 kg of special compound fertilizer as seed fertilizer. Fertilizer application is mainly carried out in the form of ditch or axe, but the fertilizer should not be in direct contact with the seed potatoes, so as to avoid degrading the seed potatoes. 3, see Miao Qiao Shi topdressing fertilizer to be early clever, generally divided into 2 times, the first time in the Qimiao, combined with cultivator soil, with decomposed human excrement 500-700 kg water pouring; second in the bud In the period, it can be 10-15 kilograms of Mushi black plus white biological fertilizer or special compound fertilizer. 4. The foliar top dressing starts from the time when the potato seedlings start to leaf, and once every 7-10 days foliar topdressing 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, 1,000 times triacontanol mixture, and even spray 3— 5 times, evenly wet the blades. 5, to supplement the rapid expansion of magnesium underground potato tubers, 50-60 grams of magnesium sulfate per plant, against the fresh water or decomposed manure, or dig shallow ditch around the plant in order to promote the rapid expansion of underground tubers.
