One time and time seedlings, strengthen the cultivator and weeding throughout the growth period, carrots need to be twice the seedlings, the first time the seedlings in the 1 to 2 true leaves, and then shallow, weeding to ensure the growth of seedlings. The second time the seedlings are in 3 to 4 true leaves, and it is better to use this to set the seedlings. The distance between the small and medium-sized cultivars is 10 centimeters, and the spacing of large-scale cultivars is 13 to 15 centimeters, and cultivators are used. Reasonable close planting is one of the important measures for the high yield of carrots. If the density is too high, the plants are easily shaded each other and the photosynthesis is weakened, especially the lower leaves are easy to rise and fall prematurely, and finally the production is reduced.
Second, we must scientifically manage the emergence of fertilizer and water to prevent water shortage. To keep the soil moist, too dry and too wet are not conducive to seed germination and unearthed. Fertilizers should be topdressed for 2 or 3 times during the growth period. The first topdressing is carried out during the groundbreaking period of carrots. In combination with watering, the mu chase acquaintances is 1,000 kg of excrement or 20 kg of urea, followed by a second or third fertilization every 20 days. Each time topdressing urea 15 ~ 20 kg, and appropriate additional small amount of potash. Into the vigorous growth of leaves, should be appropriate water control to prevent leggy.
Third, the timely harvest of carrot growth period is generally 100 to 130 days, in the middle and southern regions of Jiangxi in the late October to early November harvest is appropriate, too early will affect the yield, too late to freeze intolerant storage.
