The spring sowing carrots are very strict in the selection of varieties(plastic nursery pots). It is advisable to use early-maturing or medium-maturing small varieties that are strong in winter, difficult to convulsion, heat-resistant and disease-resistant. As far as possible before the arrival of summer, the fleshy roots have basically expanded to meet the commodity harvesting standards(1 gallon nursery pots wholesale). The carrots exported are required to be orange-red varieties with the same color of skin, meat and stem.
It is better to use tomato, kale, cabbage, eggplant, legumes and wintering spinach(plastic nursery pots wholesale).

Therefore, under the premise of selecting the varieties resistant to spring and sowing, the average temperature can be sown at 10 ° C and the average night temperature at 7 ° C(black plastic nursery pots). In the middle and lower reaches of the Yangtze River, a carrot is planted in the middle of March. The use of plastic small arch sheds or plastic greenhouses can also be broadcasted in advance as appropriate for spreading or broadcasting(3 gallon nursery pots wholesale).

(mini heavy duty plastic terracotta plant pots)The temperature at which the carrot fleshy roots expand is 18 to 25 ° C(cell trays). Carrot spring sowing summer harvest belongs to off-season cultivation. In recent years, the cultivated area has gradually increased, mainly to meet export needs. Before planting, the deep tillage is more than 30 cm, and the bricks or stones in the soil or base fertilizer are removed(5 gallon nursery pots wholesale). Spring carrots are soaked too early to convulsion, causing root defects or roots.
Generally, after 90 to 100 days of sowing, it can be harvested in batches(plastic nursery pots manufacturers). After harvesting, it can be stored in the 0-30C cold storage after pre-cooling, and can be supplied throughout the summer and autumn. In principle, as long as the soil is dry, it can be wet. Pay attention to 1 to 2 true leaf seedlings, the remaining strain is 3 cm, and the second seedling is 3 to 4 true leaves(7 gallon nursery pots wholesale).

Each time the seedlings are 6 cm apart, 4 to 5 true leaves are fixed, and the small variety is 12 cm(wholesale nursery pots). 40,000 seedlings per acre were climbed to the right, and the distance between large varieties was 15 to 18 cm, and about 30,000 plants per mu were kept(10 gallon nursery pots wholesale).

Late sowing causes the fleshy roots to swell in the above high temperature rainy season, and early maturing varieties can be harvested from early June(15 gallon nursery pots wholesale). In late June, the temperature rises above 30 °C, which inhibits the expansion of the fleshy roots and can be harvested.
