How to manage radish planting in winter?

1. The suitable growth temperature of radish stems and leaves is 15~20℃. If it is below this temperature for a short time, it can grow normally, but if it is stored at low temperature for a long time, it will stop growing. The succulent roots need higher growth temperature, and when it is lower than 6℃, the growth is slow. However, when frost occurs and the external environment temperature is lower than 0℃, the fleshy roots of radish will be frozen.

Secondly, winter and spring radishes are generally sown in June10 ~ mid-June and harvested in February ~ March. The growth period of radish is the high incidence of frost. If the varieties with poor cold tolerance are selected and placed in low temperature environment for a long time, premature bolting will easily occur, which will affect the expansion of fleshy roots and reduce the yield and quality. The open field in the north is not suitable for planting radish in winter, and the whole growth period will be affected by frost.

When there is frost, the fleshy roots of radish face low temperature, which consumes a lot of nutrients, and the cells freeze and lose water, which affects the yield and makes the frozen part inedible. So, how should radish be managed in the face of frost? When the low temperature comes, the mature radish should be harvested and stored in time, and the growing radish should be heated in time to prevent freezing injury.
