Every season, there are kinds of vegetables suitable for their own solar terms, and the scarcity of things is precious, which is suitable for the market of each product category. In the blink of an eye, when the four seasons are wintering, some farmers are busy preparing crops for wintering and some farmers start planting in winter.
In winter, because of the cold weather and temperature characteristics, there are certain requirements for the growing environment of vegetables. Some vegetables are not suitable for planting in winter if they are not cold-tolerant, and it will be more challenging to plant vegetables in the wrong season in winter.
Planting vegetables in any season has its advantages and disadvantages, and so does winter. It is well known that the weather is getting colder and colder in winter, and the temperature in some places will be very low.
Then, it is very important to know the precautions needed in winter planting in order to effectively prevent them in the planting process, so as to ensure the quality and yield of vegetables, especially for people who are full-time vegetable maintenance.
First of all, we should pay attention to prevent freezing injury when planting in winter. It will snow in many places in late winter, and it is common for the outdoor temperature to reach MINUS several degrees. Vegetables are easily frostbitten under such temperature conditions.
Secondly, it is necessary to prevent the occurrence of dead seedlings, and appropriate heat preservation measures should be taken when the temperature is low in winter, but it is not good if the temperature in the greenhouse is too high, and the temperature in the greenhouse is high and the ventilation is poor.
The first kind is the familiar radish. Although radish likes warm growing environment, it has strong cold tolerance and can still be planted in low temperature climate in winter. The cold-resistant temperature of radish is about 0 degrees, as long as the temperature is not very low, it can be planted. Choose varieties with high cold-resistant ability, and good varieties can make users worry a lot.
The second kind is lettuce, which is also a kind of cold-resistant vegetables. Lettuce seeds can germinate at about 4 degrees, the cold-resistant temperature of seedlings can reach about MINUS 6 degrees, and the temperature of 12-20 degrees can grow well. Therefore, if lettuce is planted in the south, it is no problem to plant lettuce in winter, because the climate in the south is warm in winter, and it will not rain in some areas in winter.
The third kind is Chinese cabbage, and the planting rate of Chinese cabbage is high in all parts of the country. The third kind of late autumn is a good season for cabbage planting, and it is no problem to grow cabbage in the open air in the south. If you plant Chinese cabbage in the north, you generally need to cultivate it in greenhouse, because the soil in the north is easy to freeze in winter, and greenhouse planting can effectively ensure the yield of Chinese cabbage.
