Carrot is a semi-cold vegetable. It is a biennial herb belonging to the Umbelliferae family. It is a home-made vegetable with crisp and delicious taste and high nutritional value. It contains many nutrients such as vitamins, carotene and carotenoids. Small ginseng is called. The edible portion of carrots is a tender, fleshy root with high nutritional value and is a healthy functional food.

Carrot roots are well developed. Therefore, deep-sloped land plays an important role in promoting root growth and fleshy root hypertrophy. Sandy loam with deep soil is required, and PH5-8 is more suitable. It is required that the soil moisture is 60-80% of the maximum soil water holding capacity. If the water is too high in the early stage of growth, overgrowth of the above ground part will affect the growth of fleshy roots; if the water content is insufficient in the late growth stage, the straight roots will not be able to fully inflate, resulting in a decrease in yield. . Overly viscous soils or the application of unrefined basal fertilizers can interfere with the normal growth of the fleshy roots and produce deformed roots.

Carrots are more tolerant to drought and should be properly controlled when they enter the vigorous growth period of the leaves. If necessary, they can be properly cultivated. When the roots start to enlarge, the amount of watering is increased and the water is evenly poured, but water cannot accumulate.

Carrot 7-8 real leaves when the beginning of normal fertilization, combined with watering, spraying every 20 days or so; fleshy roots began to increase when the ratio of phosphorus and potassium fertilizers to increase.

About 3 months after the carrots were harvested and planted, the roots of the carrot were formed. The more mature the roots were, the deeper the color of the roots was, and the crude fiber and starch were reduced, the sweetness was increased, the quality was soft, and the nutritional value was increased. Therefore, carrot harvesting should not be too early, but should be harvested after the meat roots are sufficiently mature and mature.
