How to grow carrots?

1. Carrots are suitable for planting in moist and well-drained deep soil. Sowing is usually carried out from late August to mid-September, and the harvest period is11-65438+February.

3. When sowing, water or manure should be poured first, and then the seedlings should be covered with soil, so that the seedlings will have greater capacity.

3. When sowing, first seed with a new high-fat film, and then sow 5-7 seeds in each nest. After sowing, the thickness of covering soil is about 2 cm, not too thick. At the same time, spraying 800 times solution of new high-fat film can keep moisture and prevent evaporation, prevent sun and drought, keep warm and prevent freezing, prevent soil hardening, suffocate and isolate pests and diseases, and improve the emergence rate.

4. When carrots emerge, they should be interplanted in time (that is, even seedlings) to avoid crowded seedlings or poor lighting, but we must master the principle of early interplanting and late seedling. When the average number of plants is 1-2 leaves, it can be planted evenly once, leaving 3 plants in each nest; When there are 3-4 leaves, the seedlings are evenly distributed for the second time; 5-6 leaves grow into seedlings, leaving 1 plant in each nest. ?

5. Spraying new high-fat film after transplanting seedlings can effectively prevent water evaporation and diseases and pests on the ground, shorten the slow seedling stage, quickly adapt to the new environment and grow healthily.

How to fertilize?

1, organic fertilizer as base fertilizer is applied at one time, and 5-6kg of urea, 0/3-17kg of diammonium phosphate and 5-7kg of potassium sulfate are applied per mu.

2. Top dressing. Urea 1 1- 13 kg and potassium sulfate 8-9 kg were applied per mu in the early stage of fleshy root swelling; Urea 9- 10 kg and potassium sulfate 5-6 kg were applied in the middle stage of fleshy root swelling.

3. Spraying 0.3% calcium nitrate and 0.2% boric acid on the leaves in the middle and late stage of topdressing outside the roots for 2-3 times to prevent calcium deficiency and boron deficiency; Spraying 0.2% potassium dihydrogen phosphate on leaves can improve yield and quality.
