Carrots have high nutritional value and are rich in multivitamins. The boron content is the highest among vegetables. Carrots also increase blood flow to the coronary arteries, lower blood lipids, lower blood pressure, and have anti-cancer effects.
The growth period of carrots is divided into vegetative growth period and reproductive growth period. The vegetative growth period can be divided into germination stage, seedling stage, continuous stalk stage, and fleshy root expansion period. The fleshy root expansion period is the key period of fertility. Carrot roots are developed, so the requirements for water are not strict, but the soil requirements are strict, and the sand loam with deep, fertile and well-drained soil is preferred.
According to comprehensive data, each 1000 kg of carrots absorbs 3.2 kg of nitrogen, 1.3 kg of phosphorus and 5 kg of potassium. Carrots have a large absorption of nitrogen and phosphorus, followed by phosphorus, but nitrogen should not be too much, otherwise it will easily cause the length of the meat to become thinner and reduce the yield.
According to the fertility characteristics and fertilizer characteristics of carrots, the fertilization should follow the principle of base fertilizer and supplemented by topdressing. Generally, on the basis of applying organic fertilizer, the application of Tianji brand potassium phosphate can be 25-30 kg per mu. .
Carrots are cultivated in both the north and the south of China. In the vast northern regions, it is one of the main winter storage vegetables due to its simple cultivation method, less pests and diseases, strong adaptability and storage resistance. At the same time, carrots are also a traditional disaster-relief crop. They are often replanted after the summer crops in the rainy season.
