1, choose the previous crop rotation, it is best not to plant carrots year after year, the previous crop had better be peanuts and other leguminous crops.

2. Select the sandy loam with good drainage, deep soil layer and convenient drainage and irrigation. Deep loosening was carried out timely after harvest, generally at the depth of 12-15cm, and above the depth of 30cm.

3. Soil preparation and fertilization is mainly in spring. Every 667m2 (1 mu) before raking, the fully mature high-quality farm manure is applied to 4000m ~ 5000kg. After raking, ridges are ridged in time to preserve soil moisture, and the ridges are wide 65cm. When ridging, deep application of compound fertilizer 10ml 15kg.

II. Variety selection and its treatment

The main results are as follows: 1. Varieties are selected according to the types of local production ecological conditions and market demand, and excellent varieties with suitable maturity, high yield and high quality are selected according to local conditions, such as conventional five-inch, six-inch, hybrid carrots and other high-quality varieties.

2. New seeds should be selected for seed selection, and grass seeds and sundries should be removed before sowing, so that the seed purity can reach 95%, purity up to 90%, germination rate up to 80%, and quality up to grade II.

3. Seed treatment: dry the seeds for 2 days before sowing. After rubbing off the seeds, soak the seeds in 40 ℃ water for 2 hours, remove and drain the water and put them into germination at 20 ℃ 25 ℃ for 4 days. When the seeds are white, they can be sown.

Third, the timely sowing date should be determined according to the characteristics of varieties, natural conditions and the pre-harvest time of local carrots. Generally in June 15-20, generally not more than August, grasp the soil moisture timely double-row sowing on the ridge, sowing deep 2cm, with sowing along with the covering soil. 20000 seedlings are preserved for every 667 square meters, and the amount of seeds used is 250-300 grams.
