When the technology was not developed in the past, carrots could not be planted in spring and summer. Since the implementation of greenhouse technology, carrots can be cultivated in early spring. So how do you cultivate the early spring carrots in the field? The following Hui Nongwang Xiaobian will study with you.
First, cold insulation
The temperature in early spring is still relatively cool. The low temperature environment is not suitable for the growth of carrots. Therefore, we must first do a good job of cold insulation. After sowing, the greenhouse can be sealed for about seven days. This is to increase the seed emergence rate.
Then, when the sun goes out every morning, open the greenhouse and let the sunlight shoot the carrot seedlings. When the sun is gradually reduced, then close the greenhouse and cover the grass.
Second, suitable distance between seedlings
There must be a problem when planting, that is, the seeding density, density is too dense and too thin is not conducive to the growth and development of carrots.
After emergence, the seedlings are carried out according to the actual situation. When the leaves of the carrot seedlings are fully unfolded and the true leaves appear, the first seedling work can be carried out at around 10:00 every morning.
The distance between each seedling is generally about 10cm, so that the seedlings and the seedlings do not grab nutrients.
Third, enhance ventilation
More than half a month after sowing, the carrot seedlings can almost all be out. When the temperature in the shed is high during the day, the shed can be properly ventilated. When the temperature drops, remember to turn it off in time.
Fourth, reasonable watering
The growth cycle of early spring carrots is not long, and the temperature is not high, so watering should not be too early or excessive. If the soil moisture in the greenhouse is high, the carrots may not be watered during the emergence period. When the meat is rooted and the temperature is fully recovered, you can pour water once.
In general, a good field management program can help carrots achieve high yields, so if you don't know how to manage carrots, then learn the techniques first.
