[Baosted base fertilizer] Carrot roots are deep into the soil and suitable for fertile and loose sandy loam. Deep tillage before planting, apply enough base fertilizer. There are two methods of application: application and ditch application. Where solid fertilizer is applied, it should be mixed with fine soil and mixed. Fertilization has a great influence on the shape of fleshy roots. When the amount of chemical fertilizer is large and the organic fertilizer is small, the proportion of deformed roots is significantly increased. Adding decomposed organic fertilizer as base fertilizer can reduce the formation of deformed fleshy roots. If the unfertilized organic fertilizer is applied, it is easy to increase the deformed root.
[Chicken application micro-fertilizer] Carrots absorb more calcium. When the calcium content is high, the content of carrot sugar and carotene will decrease. When calcium deficiency, it will cause hollow disease. The absorption of magnesium by carrot is not much, and the magnesium content is more. The more sugar and carotene content, the better the quality. The application of calcium magnesium phosphate fertilizer in the base fertilizer can be sprayed once in the seedling stage and the leaf growth stage. At the same time, it is combined with spraying new high-fat film to improve the utilization rate of effective components of fertilizer.
[reasonable topdressing] In addition to the application of base fertilizer, carrots must also be topdressed. In the later stage of growth, excessive water and fertilizer should be avoided, otherwise it will easily cause cracking and is not conducive to storage. The method of topdressing can be carried in with water, or it can be applied to human excrement and water. At the same time, spraying the fruit and strengthening the body, the nutrient transport conduit of the underground fruit is thickened, the fruit fruit is expanded and expanded, the fruit surface is smooth, the fruit shape is strong, and the quality is high.
