Carrots are usually sown in summer and fall and harvested in fall and winter. According to the climate of different regions and varieties, determine the sowing time, seedlings in the hotter season, root fertilizer in the cooler season. In order to provide fresh carrots in the summer, you can use Zhao Suzong spring wave, to avoid too long a period of low temperatures in the seedling period, to prevent seedlings through the vernalization stage caused by early autumn large.

Soil should be deep sandy good soil, PH5-8 is more suitable. Soil moisture requirements of 60% ~ 80% of the maximum soil retention, too much moisture before growth, the ground part of the growth is too good, will affect the expansion of the fleshy roots. Insufficient moisture in the late growth period, the rectus muscle can not fully expand, and the yield is reduced. Application of too sticky soil or immature base fertilizer will prevent the normal growth of fleshy roots and lead to deformed roots.

Carrot planting time

The best time to sow carrots is between summer and summer, and in recent years, due to mayor/market demand, there is also a spring onion carrot. Spring broadcasting is earlier and usually takes place from late February through early March!

Carrot planting temperature

Carrot is a half-hardy vegetables, suitable for germination temperature of 20-25, the growth of the appropriate temperature for the daytime 18-23, the night temperature of 13-18, the temperature is too high, too low is not conducive to the growth of carrots, carrots roots are developed, so the deep land has an important role in the promotion of vigorous growth of the root and the fleshy roots of the hypertrophy.

The above are the growing conditions for carrots, all of which can be collected in reserve!

Carrots are a cold temperature sensitive crop, and production of carrots for flowering and seed setting requires a vernalization treatment at the seed production stage of carrots. Vernalization treatment is the treatment of radish seeds or plants with low temperatures. Currently, Korean cold-tolerant varieties are more widely adapted, and their growth and quality are not affected by slightly lower temperatures in the early part of the season, unless they are below 10. High daytime temperatures and low nighttime temperatures in summer and fall also contribute to nutrient accumulation and expansion of fleshy roots. In addition, the range of temperatures adapted to radishes varies according to the species and variety. If the growth of the four seasons without fleshy roots is adapted to a wide range of 9 ~ 23. The growth of the same kind can be adapted to a small range of temperatures. Especially at high temperatures, it is difficult to form a fat fleshy root, and it is easy to be infected with virus diseases.
