Fertilizer should not come into direct contact with the seed lest the potatoes should be burned to death.

4. Field management

When the seedling grows 3-5 leaves, pay attention to the control of aphids; fertilize once at the early budding stage and at full flowering stage, generally add urea or 1% of potassium dihydrogen phosphate and dilatonin; pay attention to strengthen field irrigation during the expansion period of potato pieces.
