There should be no water shortage during the seedling period. Keeping the soil moist and overdrying and over-wetting are not conducive to seed germination and emergence. During the growing period, fertilizer should be topped 2 or 3 times. The first topdressing should be carried out in the groundbreak period of carrots. In combination with watering, 20 kg of urea should be topdressed, and the second fertilizer should be followed every 20 days. Kilograms can enhance the disease resistance of carrots and prevent the occurrence of cracking. Into the vigorous growth of leaves, should be appropriate water control to prevent leggy. During the root enlargement period, most of the water is needed, and the water should be poured into the ground to meet the demand. In the later period, attention should be paid to water control to prevent rot and root tumors.
