The Latest High-Yield Carrot Cultivation Techniques and Methods Tutorial
The carrot is a biennial herbaceous plant belonging to the Apiaceae family. Its fleshy root is rich in sucrose, glucose, starch, carotene, as well as potassium, calcium, phosphorus and other nutrients. Every 100 grams of fresh weight contains 1.67-12.1 mg of carotene, which is 5-7 times higher than that of tomatoes. After consumption, it is digested and broken down by the gastrointestinal tract into vitamin A, which can prevent night blindness and respiratory diseases. It can be stir-fried, boiled, pickled in sauce, salted, etc. It stores well. It is distributed all over the world, and is cultivated in both northern and southern China, with its output ranking second among root vegetables.
Biological Characteristics of Carrots
The carrot root system is a taproot system, with the main roots distributed within a 20-90 cm soil layer, reaching 180-250 cm deep. The upper part of the taproot, including a small portion of the hypocotyl, thickens to form the fleshy root, on which four rows of slender lateral roots are borne. The leaves grow in clusters on the shortened stem, are tripinnate compound leaves, with slender petioles, dark green in color, small in area, and densely covered with fine hairs. After the fleshy root is stored through the winter, it bolts and flowers, first producing the main bolt, then lateral branches, forming a compound umbel inflorescence. The seed embryo is very small, often underdeveloped or without an embryo, with poor emergence capacity, and the germination rate is as low as about 70%.
The phase development of carrots belongs to the green-body vernalization type. If sown too early in spring, once the seedlings reach a certain size, they will bolt prematurely due to receiving a longer period of low temperature. The vegetative growth period is 90-140 days, the germination period is about 10-15 days, the seedling period is about 25 days, the leaf growth period is about 30 days, followed by the fleshy root growth period of 30-70 days. Seeds can germinate at 4-6°C, with the optimum germination temperature being 20-25°C. The leaves have strong adaptability in growth, and the taproot enlargement period requires 13-23°C, with a night temperature of 13-18°C. The soil should be sandy soil, with a pH of 5-8, and the soil moisture requirement is 60-80% of field capacity.
