Carrot is a deep-rooted fertilizer-loving crop. Because of its rapid growth and short growth period, it needs a large amount of fertilizer, so it is necessary to choose a plot with deep soil layer, fertile soil, rich organic matter content and easy drainage and irrigation. Soil fertilization is mainly based on base fertilizer, supplemented by topdressing, and the amount of fertilizer should be fully decomposed. When fertilizing, the organic fertilizer that is not decomposed should be strictly used as the base fertilizer. Under normal circumstances, it is recommended to apply compost, manure or human excrement and urine at a rate of 5,000 kg per mu, and spread it all over the floor. Farmers who have planted carrots should know very well that this vegetable is very simple in both planting and later management, and basically does not need to be cultivated too much. As long as the water and fertilizer can keep up, farmers will not be disappointed in the harvest season.

During the sowing period, the middle and lower reaches of the Yangtze River are sown in August. When sowing, the seeds are rubbed off first, mainly by drilling or broadcasting. After sowing, cover with shallow soil to suppress, then spread with thin soil and miscellaneous fertilizer and cover with grass to keep soil moisture and prevent rain damage. Base fertilizer: it is best to choose well-decomposed farm manure as the base fertilizer, and the manure should be fine and broken. The base fertilizer can be about 5000 kg per mu, and the combined use of nitrogen, phosphorus and potassium compound fertilizer can be about120 ~160 kg. Then deep ploughing is carried out to make the soil and fertilizer blend in the soil. The management in actual growth is like this. When carrots grow to the thickness of fingers, water them in time, irrigate them regularly and evenly, and keep the soil moist, but there can be no water accumulation. We observed that the land should be watered as soon as it turns white, and the amount of water must be small. If possible, it is best to use sprinkler irrigation.

Soil preparation Before sowing, it is necessary to deeply plough the land, then apply enough farm manure as base fertilizer, and then turn the land into flat land. After turning, if you want to drill, you can make a border, which is not too high, but you must water it. In the seedling stage, the cutworm is harmful, and it can be prevented by mixing 500 grams of matrine with fertilizer per mu during soil preparation. If there are still pests in the growth process, trichlorfon and fried oil cake can be used as poison bait and sprinkled into the fields in the evening to prevent and control them.
