After the carrots are planted, the carrots are planted in the loose and fertile sandy loam soil due to the deep roots. Before ploughing, deep tillage is carried out, and after fertilization, solid fertilizer and fine soil are mixed and mixed. Fertilization has a great influence on the fleshy roots of carrots. When the application of chemical fertilizers is too much and the application of organic fertilizers is too small, the deformed carrot roots will gradually increase. In order to effectively reduce the formation of deformed fleshy roots, high-quality decomposed organic fertilizer should be applied as a base fertilizer. Carrots are applied with high-quality decomposed manure and human excrement 2000-2500kg per acre, 15-20kg of superphosphate, and 100-150kg of plant ash. Or only apply chemical fertilizer, apply 20kg of ammonium sulfate per acre, 30-40kg of superphosphate, 30-35kg of potassium sulfate. Carrots should be topdressed in addition to the base fertilizer. In the late stage of carrot growth, it should be effective to avoid excessive water and fertilizer, which will cause the root of carrot meat to crack. When the carrot is topdressed, it can be watered for pouring. At the same time, it is also possible to add water to human excrement and urine.
Carrot micro-fertilizer application should pay attention to, because carrots absorb more calcium, calcium will reduce the sugar content of carrots, it is easy to cause hollow disease; carrot micro-fertilizer, can be combined with spraying new high-fat film, can improve the active ingredients of fertilizer . After the carrot is fertilized, the fruit can be sprayed with the fruit to make the sub-fruits absorb enough nutrients, thereby increasing the growth of the carrots, making the carrots grow stronger and improve the quality and high yield.
