When they grow in the winter, they are required to cover the soil surface with a membrane or to build a large shed to maintain a suitable temperature and humidity. In the case of insufficient sunlight, life lights can be used to supplement the light, to promote light co-operation, to avoid defusing the soil and to avoid freezing. Outdoor water needs to be watered before the freeze period and every other week in the shed。
The technology for the winter of the cabbage
When growing in winter, cabbage can cover the surface of the soil with a transparent membrane, or be bred directly into a large shed to protect the temperature and humidity, as much as possible to control the growth temperature at around 15°c, and to facilitate the growth of seed sprouts and leaf sprouts, which can significantly improve the yield and quality of fruit。
Because of insufficient exposures to winter sunlight, to promote the growth of cabbage, lifelights can be used to radiate strains, supplement light, maintain normal operation for light cooperation and accelerate nutrient formation. Maintaining air moisture of about 65 per cent avoids the drying of leaves and slow growth。
In winter, when growing cabbage, outdoor water is required to take place before the soil is frozen, and every other week when growing in the shed, the water temperature needs to be close to room temperature to avoid freezing. When growth slows, small amounts of fermented organic fertilizers or urea can be applied to promote growth。
During the winter season, the cabbage does not take pine earth steps to avoid large amounts of evaporation, resulting in freezing of roots and freezing to death, resulting in slow growth and halt of plants. When a dying, decaying leaf is produced, it is not trimmed in time, and when it is slowly growing, the leaf dies and falls。
