When is the right time to sow carrots?Greenhouse-grown carrots are usually sown in late January to early to mid-February and harvested in April.

Spring mulch cultivation carrots are sown in March-April and harvested in late May. For open-field cultivation in summer, sowing can be done in May-June and harvesting in July-August. In high-latitude and high-altitude areas such as Xinjiang, sowing can be done in early June and harvesting can be done in September-October. In Hebei Province, Shanxi Province, Henan Province and other places in the Yellow River Basin, sowing can be done in early to mid-July and harvesting can be done in October-November.

Carrot seed planting precautionsOnly by selecting the most suitable varieties for the local area in different seasons according to local environmental and soil conditions can we obtain high-quality and high-yield carrots. Carrot seeds have a short lifespan, so it is best to choose new seeds of the current year or seeds from the previous year for sowing. When sowing carrots in hot seasons, it is best to place the seeds in a well, air-raid shelter, sweet potato cellar, cave, or other place with a lower temperature for germination to increase the germination rate . In addition, carrot seeds are often stuck together. After drying the seeds before sowing, rub off the prickles to facilitate uniform sowing . Carrot sowing amount and methodThe sowing amount of carrots is generally 300-500 grams per acre . Generally, row sowing is adopted with a row spacing of 15-20 cm and sowing after digging a 2 cm furrow. After sowing, just sweep the ground with a broom to level it. To prevent weeds, use herbicides once within 3 days after sowing to reduce the workload. After sowing in the hot season, cover with a layer of straw mats or other covering materials to keep the soil moist. After the carrots emerge, uncover the covering materials in the afternoon and start normal management. |
