Carrot is rich in nutrients, contains more carotene, sugar and calcium, phosphorus, iron and other mineral elements. It is known as a small ginseng. However, in the cultivation process, due to improper fertilization, it often results in phenomena such as cracking roots, hollowness, malformation, quality aging, and woodiness. Therefore, scientific and rational fertilizers should be applied. The characteristics of fertilizer requirements and fertilization techniques are described as follows: I. Fertility requirements Carrots are a type of vegetable that requires a large amount of fertilizer. Studies have shown that the production of 1000 kilograms of carrots requires 2.4 kg of pure nitrogen, 0.8 kg of phosphorus pentoxide, and potassium oxide. 5.7 kg. Different stages of carrot growth and development, the required nutrient content is also very different. In the two months after sowing, the absorption of each factor was small, and the growth rapidly increased when the roots began to swell in the middle and late periods. The absorption of nutrients increased with the increase in the amount of fertility. The maximum amount of potassium was absorbed, followed by nitrogen, phosphorus. Second, fertilization technology 1, basal carrot root deep into the soil, suitable for loose fertile sandy loam. Before planting, deep plowing should be applied and basic fertilizer applied. In general, 2000-2500 kg organic fertilizer is applied per mu, and 30-40 kg of Stanley compound fertilizer. 2, top dressing carrots In addition to the use of base fertilizer, but also dressing 2 to 3 times. The first time is 20 to 25 days after emergence. After growing 3 to 4 true leaves, 5 to 10 kg of potassium sulfate compound fertilizer is applied per mu. The second topdressing is carried out after the carrots are seeded, and 10 to 15 kg of potassium sulfate compound fertilizer can be used per mu. The third top-dressing in the root swelling stage, per acre of potassium sulfate compound fertilizer 15 to 20 kg. 3, foliar carrots absorb more boron. It can be sprayed once in the seedling stage and the leaf growth stage respectively, and boric acid solution or borax solution with 0.1% to 0.5% twice in the root swelling stage.
