1, selection of land preparation: choose a higher terrain, loose soil, good drainage and irrigation of loamy soil, and deep plowing, to keep the bed level, and apply basal fertilizer. 2, seed treatment: select the growth of healthy, not suffered from pests and diseases of the seeds for soaking treatment. 3, sowing: carrot sowing method to hole sowing, scattering based on the sowing method, sowing the appropriate mulch to keep the soil moist. 4, Field management: do a good job of irrigation, fertilizer, inter-seedling, mid-tillage weeding, pest control and other work.

A carrot planting technology

1, selecting the land rectification

carrot is suitable for growth in the higher terrain, loose soil, drainage and irrigation of good loamy soil, do not choose the soil viscous soil, so as not to affect the growth of the fruit. Before planting, the land should be y ploughed, keep the bed level, remove weeds and apply basal fertilizer to ensure nutrition, generally available rotted organic fertilizer.

2, seed treatment

Pick the growth of healthy, not suffered from pests and diseases of the seed, and then soaked in 37 ℃ warm water, waiting for 12-16 hours to fish out, fish out placed in the shade to dry, which can facilitate the later emergence of seedlings.

3, sowing

Sowing methods are mainly hole sowing and scattering. Sow carrot seeds evenly into the soil, and then cover the soil appropriately, keep the soil moist, and promote the germination of carrot seeds and seedlings.

4, field management

(1) reasonable irrigation: the growth of carrots require a large amount of water, need to be timely and appropriate amount of supply, the general choice of every 2-3 days of watering, every time you watering the soil can be wet after watering, don't stagnant water.

(2) staged fertilizer: generally between the carrot break white to the expansion period, the pursuit of a thin fertilizer water. Do not over-concentrate fertilizer or fertilizer too close to the roots, resulting in burning roots. If sufficient base fertilizer is applied, then the amount of fertilizer can be appropriately reduced when planting.

(3) timely inter-seedling: after the carrot seedlings, we should appropriately increase the time of inter-seedling, delayed seedling fixation, to ensure that the whole seedling of the carrot strong seedling rate. If it is sown, then the first inter-seedling is carried out when the seedlings appear two true leaves; if it is sown in the hole, it can be inter-seeded about 7 days after the emergence of seedlings.

(3) Plowing and weeding: usually after the first inter-seedling, you can carry out a plowing and weeding work to promote the growth of seedlings. You can also combine inter-seedling, weeding and plowing to save labor.

(4) pest control: carrot growth period focus on the prevention and control of cabbage greenfly, aphids, yellow stripe flea beetles and so on. Aphids can be prevented and treated with 10% aphid net 10 grams / mu of water 50 kg spray. Prevention of cabbage greenfly, yellow stripe flea beetle available Bt300 times liquid plus insecticide double 500 times liquid or 5% inhibit too much spray 1500 times liquid.

Second, the difference between carrots and carrots

1, the family is different

carrots for the cruciferous radish genus of biennial herbs; carrots are umbelliferae carrot biennial herbs.

2, the appearance of different

3, the taste is different

carrots full of water, the taste is more crunchy, with a little bit of sweetness, but also a little bit spicy; carrots with a certain toughness, less water, eaten in the raw taste sweet, the texture is harder.

4, different nutrients

carrots contain more dietary fiber; carrots in the carotenoid content is rich.
