1. Choose a variety. Choose red carrots with good root shape, good quality, and strong growth potential. Commonly used varieties include five-inch summer time, three-inch Yantai, five-inch red radish, and Japanese black five-inch high-quality local varieties.

2. Selected plots. The sandy loam with deep soil, loose air, and energy irrigation should be chosen so as to facilitate the formation of good-quality fleshy roots. The most suitable carrots are cucumbers, tomatoes and onions, garlic, etc. In addition, wheat is a suitable fore crop. Carrots can also be intercropped with high-stem crops such as corn, using high-stem crops to shade, reduce field temperatures, and facilitate the growth of fleshy roots.

3. Soil preparation. Carrot meat roots into the soil deep, Wang Yong should be deep-turned more than 30 cm, combined with deep turning sun 10 to 15 days. Carrot production is high, the amount of fertilizer required is large, combined with deep-turning Mushi rotted organic fertilizer 3000 ~ 5000 kg, available nitrogen fertilizer 7.5 ~ 10 kg, plant ash 50 kg or potassium sulfate 20 kg. Basal fertilizer should be even and avoid fork roots.

4. Make it flat. After deep-rooting the sun, the soil is finely chopped, leveled, and dried. Carrots can be cultivated flat, but they can also be cultivated in high ridges, and they can be specifically determined according to the conditions of light and precipitation in each place. During the cultivation of high ridges, the ridge spacing is about 20 cm, the ridge width is 50 to 70 cm, and the height is 10 to 15 cm.

5. Fine sowing. Carrot seeds have a low germination rate and are difficult to emerge. Seeds should be treated before sowing. Select new seeds, dry for 1 to 2 days, then remove the bristles, soak for 4 to 8 hours before sowing, drench the water and infiltrate the fine sand or plant ash for sowing. Sowing depth 1 ~ 1.5 cm. Carrots generally sprout 6 to 10 days after sowing. A small amount (2%) of Chinese cabbage seeds was mixed at the time of sowing. The cabbage seedlings could protect the carrots from sun rays and heat.

6. Marrow weeding. 1 to 2 true leaf time seedlings, spacing 3 cm. Then in between the rows, weeding and weeding ensure the growth of seedlings. 3 to 4 true leaves when the secondary seedlings, 4 to 5 leaves Dingmiao, small and medium-sized species spacing is 10 cm, large-scale plant spacing 13 to 15 cm, and cultivator, weeding. Carpet seedlings are prone to grass shortage. In addition to cultivating and weeding, herbicides can also be used.

7. Reasonably water. Carrot sprouting period should be poured 2 to 3 times water, moist soil is conducive to the germination of the seed germination, Miao complete. Seedling period before the promotion of control. After the "fixation period", when the thickness of the root of the fleshy root is approximately equal to that of the finger, it is the period during which the fleshy root grows fastest, and it should be watered in time to keep the soil moist. If the water supply is insufficient, the xylem of the fleshy root is likely to be corked and the lateral roots are increased. If the early drought is followed by excessive watering, the fleshy root will be cracked and the product quality will be reduced. Stop watering in the first half of the harvest.

8. Disease prevention and pest control. The main diseases of carrots are black spot, black rot and soft rot, 75% chlorothalonil 600 times or 70% mancozeb 600 times, spray every 7 to 10 days, even spray 2~ 3 times; its main pest is the carrot root line can be used 40% dimethoate 1000 times spray control.
