Potato management in spring

After the emergence of potato seedlings with early fertilization, some drought applied 1000-1500 kg of high-quality dung to achieve the purpose of both drought resistance and nutrition. When the soil moisture is good, 10-15 kg of urea is applied in holes, and 15 kg of urea is applied per mu when the seedlings grow to 50 cm. The first hole application was dug in the middle of four potatoes, and the second hole was applied in the middle of two holes in order to improve fertilizer utilization.
Early watering and early spring is dry weather. If there are cracks in the border after the emergence of all the seedlings, the soil in the field should always be kept moist when the border surface is moist and drained, especially when the potato is expanded.
