1、 Planting time

The planting time of carrot is divided into two crops, mainly in summer, that is, sowing seeds in July and August, so that they can be harvested in November. With the demand of the market, there are also varieties sown in spring. The earlier time should be from February to March. If the open air temperature is low at this time, it can be selected from mid and late March to early April. If it is sown too early, the bolting time is correspondingly advanced, and it is easy to be flooded if it is sown too late

2、 Planting technology

1. It is suitable for growing in loam with deep soil layer and good drainage effect. If the soil is sticky, it is necessary to ensure good and smooth drainage, which determines whether the cultivation is successful. The land is deeply cultivated, and the base fertilizer is applied to ensure nutrition. Rotten organic fertilizer can be selected

2. Select suitable seeds, soak them in warm water at 37 ℃ before sowing, wait for 12-16 hours, and then take them out and dry them in a cool place, which is conducive to seedling emergence in the later stage

3. Before sowing, rake the soil several times to ensure that the surface layer is flat. Sprinkle seeds on it and cover it with 1.5cm soil layer. In order to ensure uniform sowing, sand can be mixed inside

4. After sowing, pour enough water to ensure that the soil is wet, so as to make the seeds full of vitality. Their emergence speed is very slow, and weeds often grow first, so they need to be sprayed with pesticides to remove weeds
