1. Land selection: carrots are plants with developed roots, which need to be planted in deep and fertile plots, and the soil water content needs to reach 60%-80%. 2. Sowing date: The sowing date of carrots is generally in the spring and autumn, so it should not be too early or too late. 3. Sowing method: carrots need to choose the correct sowing method, such as organic drilling, liquid sowing, on-demand sowing and so on. 4. Planting management: it is necessary to control the growth temperature of carrots and ensure the soil moisture of carrots.
First, land selection.
1. Planting requires a sandy land with fertile soil, deep soil layer and rich humus content in Junze.
2. The topsoil of the soil should be about 40-60 cm, not shallower than 30 cm, creating a good soil environment for carrots.
3. The water content of clods should reach 60%-80%. If the soil moisture is not enough, carrots will have rough meat, uneven shape and thin roots. If the humidity is too high, it will lead to the growth of tumors on the surface of carrots, which is easy to crack the roots.
3. Before sowing, the plot needs to be prepared in the field, ploughed and prepared for drainage. When applying base fertilizer to the plot, the base fertilizer should be applied 3-5 days before sowing. After application, it needs to be plowed and raked together with the fertilizer, and the fertilizer should be evenly buried in the soil layer below 6 cm.
Second, sowing time.
1. Carrots are suitable for planting in spring and autumn;
(1) In spring, carrots are usually sown in February and harvested from May to July.
(2) In autumn, gourd wave is sown in July, and can be harvested in11-65438+February.
2, according to different regions, the termination time of carrots is different:
(1) In the middle and lower reaches of the Yangtze River, carrots are usually sown in early August and harvested at the end of 1 1.
(2) In Guangdong, Fujian and other coastal areas, carrots can be planted from August to June and harvested in winter.
(3) North China is generally sown in early July and harvested in the middle of165438+1October.
(4) In cold areas, such as Xinjiang, the sowing time can be advanced to early June, and the harvest can be achieved in 10.
Third, the sowing method
1, machine drilling: drill drilling in the field with smaller seeds.
2. Liquid sowing: Carrot seeds are germinated with water seeds and made into suspension, and the suspension is sprayed with a seeder or sprayer for sowing.
3. Hole sowing: determine the sowing density before sowing, and sow carrot seeds into the soil according to the hole distance.
4. Sowing: Sowing is generally carried out in the weather where the temperature is higher than 10 degrees, and the germinated carrot seeds are scattered on the clods.
Fourth, planting management.
1. Radish needs to be interplanted three times after sowing. If interplanting or not interplanting in advance, carrot seedlings will be blown down by the wind because they are too small and thin, and the planting density will be too dense, which will also lead to root cracking and rough epidermis.
2. Within 60 days after sowing, moderate watering is needed to avoid carrot drought. Water needs to seep from top to bottom, but not too much to avoid carrot disease.
3. The weeds in the carrot field have strong vitality. Plot planting will compete for the nutrients of carrots, so it is necessary to use herbicides or pull weeds manually in time.
4. After sowing for 3 months, cracks appeared in the soil at the roots of carrots, and the leaves of carrots began to turn yellow, so carrots could be harvested.
