Thin seedling carrots are happy, and over-dense planting is not conducive to the formation of succulent roots. Therefore, it takes time for seedlings to emerge after they are all ready. The first thinning is carried out with 1 to 2 true leaves and the height of the seedlings is 3 cm, and the density of the remaining thinning is preferably 3 to 5 square centimeters. The second thinning is carried out when the seedlings are 7 to 10 cm high and 6 to 7 squared. It is advisable to keep seedlings in centimeters; the third time is to set seedlings, when the plant height is 15 to 20 cm, it is appropriate to 10 square centimeters, and large varieties are preferably 15 to 20 cm square, and each seedling is 30,000 to 50,000. The growth period of topdressing carrots is long. In addition to base fertilizer, topdressing must be performed 2 or 3 times. However, the amount of nitrogen fertilizer must be controlled, otherwise the leaves will grow excessively, which will affect the expansion of fleshy root. The first fertilizer application was carried out 20 to 25 days after emergence, at the age of 3 to 4 true leaves, 2 kg of urea, 3 to 4 kg of superphosphate, and 2 kg of potassium chloride per acre, plus a small amount of rotten cooked manure and urine. 1,500 kg of topdressing with water; the second topdressing was carried out 40 to 50 days after seedling emergence (after seedling setting), 4 kg of urea per acre, 4 kg of superphosphate, 3.5 kg of potassium chloride, and a small amount of rotten manure 1,500 kg of water was applied. Irrigation carrots have a small leaf area, low evaporation, developed root systems, strong absorptive capacity, and are relatively drought tolerant, but in the summer and autumn dry seasons, especially when the roots are swollen, appropriate irrigation is required. Generally, the humidity of the soil should be maintained at 60% to 80%. If the water supply is insufficient, the fleshy roots are thin and rough; if the water supply is uneven and suddenly dry and wet, it may easily cause cracked roots. After the fleshy roots are fully expanded, watering should be stopped to prevent rotten roots. Disclaimer: Some articles on this website are transferred from the Internet.
