Plants cannot grow without sufficient nutrients, and carrots are no exception. In the process of planting carrots, growers need to apply fertilizer reasonably for many times to achieve high yield of carrots. So the question is, how to fertilize carrots? We need to conduct targeted fertilization after understanding the fertilizer demand characteristics of carrots, so as to meet the nutrients required for carrot growth. First, sufficient base fertilizer should be applied. Before planting carrots, sufficient base fertilizer should be applied in combination with land reclamation to provide a good nutritional basis for carrot growth and ensure long-term nutrient supply. As for the selection of carrot base fertilizer, it is generally based on fully decomposed farm manure, supplemented by a certain compound fertilizer, which can balance various types of nutrients. Second, reasonable topdressing. In addition to applying sufficient base fertilizer, carrots generally need to be topdressed about three times after emergence to ensure that the nutrient requirements of carrots in the rapid growth period are met. In terms of the amount of topdressing, we should pay attention to less before more. As for the type of topdressing, remember not to apply nitrogen fertilizer on a biased basis, but to combine a small amount of nitrogen fertilizer with phosphorus and potassium fertilizer. To be specific, the first topdressing is carried out about when the carrots grow three real leaves, the second topdressing is carried out when the carrots are fixed, and the third topdressing is carried out when the fleshy roots of the carrots develop and expand. Each fertilization is slightly more than the previous one. |
