Carrots are important vegetables in our country. They are generally planted in autumn and spring. Their fleshy roots like loose and fertile soil, and they have a high demand for potassium, which can help the formation of carrot roots in the cambium and easily increase production. Then carrots are correct What are the fertilization methods?

1. Base fertilizer

Because carrots are suitable for fleshy roots, the fertility of the soil layer should be high. Before sowing, deep ploughing is required for 25-30 cm, and decomposed farmyard manure is applied. The dosage is about 2500 kg, and a small amount can be applied. Phosphate fertilizer and potash fertilizer, if the organic fertilizer is insufficient, you need to supplement the appropriate amount of urea, if possible, you can also use calcium magnesium phosphate fertilizer.

2. Top dressing

After the carrots are fixed, they need to do a good job of cultivating and weeding. The first topdressing is in the seedling stage, and a small amount of biogas slurry is applied. When the fleshy roots are growing, the amount of fertilizer and water must be controlled, otherwise it will cause fertilizer damage, cracked roots, and affect the carrots. Commercial quality, the fertilizer is mainly urea, which promotes the expansion and growth of fleshy roots. Pay attention to the application of fertilizer with water.

3. Spray fertilizer on foliage

One month before the carrots are harvested, potassium dihydrogen phosphate can be sprayed with water on the leaf surface. If the soil is deficient in boron, you can also spray 0.1%~0.3% borax aqueous solution. If the aboveground part of the carrot is prosperous, you can use paclobutrazol. Spray the wettable powder.

4. Trace element fertilizer

Carrots like calcium fertilizer very much. When the calcium content is high, the sugar and carotene content of carrots will decrease, and calcium deficiency will also cause hollow disease; spray calcium fertilizer once at the seedling stage and leaf growth stage, and spray twice for photosynthesis during the fleshy root growth stage. Nutrient film fertilizer and borax solution.
