High-yielding cultivation techniques for carrots in spring

1. Use good varieties: It is recommended to select high-yield and high-quality varieties suitable for spring sowing, such as "Red Beauty" and "Kuroda Five-inch". 2. Choose plots and fertilize the land: fertile, well-drained sandy soil, 4,000 kg of organic manure before maturity and 50 kg of ternary fertilizer. Organic manure must be fully decomposed, finely crushed, and fully applied. Mix well with the soil. Otherwise, it will damage the main root. 3. Rigging: Apply enough basal fertilizer to rid it after leveling the ground. Rigging specifications: ridge width 50 cm, height 20 cm. Before the ridging, two trenches were opened, and 30 kg of compound fertilizer was applied in Mushi, and the ridge was turned into the soil. 4. Seeding, filming (1) Seed treatment: soaking seeds to soak the seeds, immerse the seeds in water at 40°C-45°C, soak for about 2 hours, take them out and place them at an air temperature of 20-25°C, keep them moist, and turn them frequently. Some seed germs can be sown when exposed. (2) sowing: Spring sowing is generally 10 centimeters in temperature kept at 12 °C sowing. Each ridge is planted in two rows, with a 20 cm row spacing, and the seeds are evenly planted along the ditch, covering 0.5 cm to 1 cm thick. In general, 250 grams of seed are used. (3) Spraying herbicides: Spray 33% of the weeds on the ground with no spray or heavy spray. (4) Cover: In order to increase the emergence rate, the mulch film shall be covered immediately after the herbicide is sprayed, and the film shall be peeled off before the emergence. 5. Field management (1) Saplings and Dinglings: After sowing for 20 days, grow 2 to 3 true leaves for 5 days. In the seedlings grow 5 - 7 true leaves when the seedlings, seedlings from 10 cm. (2) Dressing: During the growth period, fertilization is generally conducted twice, in 3 to 4 true leaves and 7 to 8 true leaves. Every time 30 kg of compound fertilizer is applied, it is applied in the middle and lower part of the ridge shoulder and then covered with soil. (3) Watering: keep the ground moist before emergence, generally not more watering, appropriate seedlings; leaf vigorous growth period, appropriate control of water; in the root swelling of the meat should maintain adequate water supply. Note that the ground must not be dry and damp to prevent cracking. (4) Cultivating soil: Before the roots of the fleshy roots are swollen, the soil is immersed in the roots so as to prevent the light from turning green and reduce the quality. 6. Harvesting: The harvest can be carried out after the fleshy roots are fully swollen. Harvesting can affect the yield too early, but later it will make the root tissue of the flesh grow old, easy to form crooked heart and reduce quality.
