How should potatoes be fertilized when planting? Here is a method
You can refer to the following methods for fertilizing potatoes:
Apply plenty of base fertilizer. The base fertilizer should be mainly organic fertilizer, and a bio-organic fertilizer should also be applied well and generously, that is, on the basis of applying 2500-3000 kg of decomposed organic fertilizer per mu, apply 45-50 kg of bio-organic fertilizer per mu. When preparing the land and digging the planting holes, mix the base fertilizer thoroughly and evenly with the soil in the planting holes, and then you can plant.
Apply seed fertilizer as appropriate. When the base fertilizer is insufficient or there is no time to fertilize before plowing, a special compound mixed fertilizer is often applied at 15-20 kg per mu as seed fertilizer at sowing. Seed fertilizer is mainly applied by furrow application or hole application, but the fertilizer should not come into direct contact with the seed potatoes to avoid burning the seed potatoes.
Apply topdressing skillfully according to the seedlings. Topdressing should be done early and skillfully, generally in 2 applications. The first is at the full seedling stage, combined with intertillage and earthing up, using 500-700 kg of decomposed human manure and urine diluted with water for irrigation; the second is at the bud stage, when 10-15 kg per mu of Heijiabai biological fertilizer or special compound mixed fertilizer can be applied.
Foliar topdressing. Starting from the stage when potato seedlings begin to unfold leaves, apply a foliar topdressing once every 7-10 days of a mixed solution of 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, and 1000-fold triacontanol, spraying 3-5 times in succession, evenly wetting the leaves.
Supplement magnesium fertilizer. During the period when potato underground tubers expand rapidly, apply 50-60 g of magnesium sulfate per plant, drenching with clean water or decomposed manure water, or applying it in shallow furrows dug around the plants, to promote rapid expansion of the underground tubers.
