Potatoes, commonly known as potatoes, are a nutritious food and food combination. The principle of high yield and high quality fertilization of potato is: the base fertilizer is sufficient, the topdressing should be diligent, the nitrogen, phosphorus and potassium should be reasonable, the magnesium fertilizer can not be lacking, the root application and the foliar application are combined, the specific methods are as follows:
Applying the base fertilizer to the base fertilizer is based on organic fertilizer, and applying the bio-organic fertilizer, that is, applying 2500-3000 kg of decomposed organic fertilizer per mu, and applying 45-50 kg of bio-organic fertilizer per mu. When digging the ground for planting the ground, the base fertilizer and the soil in the planting hole are fully stirred and evenly planted.
When the application of the fertilizer is insufficient, or when the cultivated land is too late to fertilize, it is often used as a seed fertilizer when planting a special compound fertilizer of 15-20 kg. The application of seed fertilizer is mainly carried out by means of ditch application or acupoint application, but the fertilizer should not be in direct contact with the seed potato to avoid burning the seed potato.
Look at Miao Qiao application of topdressing and topdressing as early as possible, generally divided into 2 times, the first time in Qi Miao, combined with cultivating soil, using 500-700 kg of decomposed manure urine for water; the second time in the bud period Can be applied to black plus white biological fertilizer or special compound fertilizer 10-15 kg.
Foliar topdressing starts from the time when the potato seedlings start to spread the leaves, and once every 7-10 days, the leaves are topped with 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, 1000 times triacontanol mixture, and sprayed 3-5 times. , evenly spray the blades.
Supplementing the period of rapid expansion of the underground tubers of magnesium fertilizer potato, 50-60 g of magnesium sulfate per plant, drenching with clear water or decomposed manure, or digging shallow ditch around the plant to promote rapid expansion of underground tubers.
