1, turn over the audience
To plant carrots, you should choose fields with different families of previous crops and carrots, then clean up the fields after harvest, remove crop waste, and turn over the soil with a hoe for 20 cm to make the soil fine and flat.
Step 2 sow seeds
The most suitable sowing time for carrots is February in spring or July in autumn. First, dig planting ditches in the field, and then sow at the spacing of 12 cm, with 2-3 seeds per hole. After sowing, cover the soil 1- 1.2 cm, and the seedlings can be thinned when they grow 2-3 true leaves.
Step 3 cover the soil to keep warm
After sowing carrots, cover the seeds with fine soil to prevent the seeds from being pecked by birds and affect the germination rate, and cover the soil with a layer of straw to keep warm and accelerate the germination.
Yield per mu of carrot and its maintenance method
1, yield per mu
Generally, the yield of carrots is about 5000 Jin per mu. Different planting areas, environmental climate and management methods will affect the yield, and the yield will be different under different management methods. Under scientific management, the yield per mu can reach about 1 10,000 kg, and it can reach 9000-1.3,000 kg with sufficient fertilizer and water.
2. Maintenance methods
Within two months after sowing carrot seeds, the soil should be kept moist and not watered, and the seedlings should be watered in time after growing. In addition, after the three real leaves grow, ammonium sulfate and potassium fertilizer should be mixed, foliar fertilizer should be sprayed when the leaves grow vigorously, nutrients should be supplemented in the middle and late stage of planting, and water should be applied after fertilization.
During carrot planting, intertillage weeding is needed. Weeds are extremely tenacious. When they grow, they will rob the water and fertilizer in the soil and block the light. Regular weeding is beneficial to the healthy growth of plants. Herbicide ether can be sprayed when weeds are pulled out in the field to inhibit weed growth.
