Analysis on the best planting time and high-yield planting techniques of carrot
When is the best time to grow carrots? How to produce high yields? The best time for planting carrots is in the heat and heat, from late February to early March. For the high-yield planting techniques of carrots, Xiaobian will explain in detail below, I hope everyone can help.
1, the best time for carrot cultivation
a, the best planting time for carrots is between the heat and the heat.
b. The best planting time for spring sowing carrots: from late February to early March.
2. Suitable temperature for carrot planting
a. Carrots are semi-hardy vegetables, the most suitable temperature for germination is in the range of 20-25 degrees, the optimal growth temperature during the day is 18-23 degrees, and the optimal growth temperature at night is 13-18 degrees.
b. During the growth of carrots, the temperature is too high or too low is not conducive to the growth of carrots.
c. Because carrot roots are relatively developed, in the process of planting carrots, deep rooting of the soil can effectively promote the vigorous growth of carrot roots and the hypertrophy of fleshy roots.
3. Soil requirements for carrot planting
a. When planting carrots, it is best to choose deep sandy loam with a pH of 5-8.
b. Soil requirements: The soil moisture is required to be 60-80% of the maximum water holding capacity of the soil.
c. The growth of carrots in the early stage is relatively high, which will make the growth of the aboveground part more vigorous, thus affecting the growth of the fleshy roots.
d. The growth of carrots in the late stage is relatively small, which will make the straight roots not fully expand and reduce the yield of carrots.
4, carrot seedling watering and fertilization
a. When the seedlings are 7-8 leaves, the deep seedlings are carried out while the soil is in a humid state, which promotes the development of the main roots and the roots, and can effectively inhibit the leaves.
b. When the fleshy root of the carrot is obviously enlarged, the water required for the growth of the carrot is satisfied, so that the soil remains wet.
c. When carrots are 3-4 pieces of true leaves, apply 2-3 kg of ammonium sulfate, 3-4 kg of superphosphate, and 2-3 kg of potassium fertilizer per mu.
d. When the seedlings are combined with watering, 10kg of diammonium phosphate and 3-4kg of potassium chloride are applied per mu, so that the carrot seedlings can promote the rapid growth of the seedlings.
e. When the fleshy root begins to grow, apply quick-acting organic liquid fertilizer or diammonium phosphate or potassium chloride per mu.
4, carrot harvest time
a, spring carrot: harvested 90-100 days after sowing.
b. Autumn carrots: harvested and stored before the onset of winter.
