What should the latest spinach pay attention to overwintering?

Vegetables in winter are no longer as rare as they used to be. Some vegetables are grown in many places in winter, and spinach is one of the choices of many people. When planting in winter, temperature is a big problem, so what problems should spinach pay attention to overwintering at this time? Let's learn about a few key points for spinach overwintering.

1. Increase weight and promote growth

Before the winter, the size of spinach is very important, small has no resistance to low temperature, larger external contact area, more likely to be frozen. Before overwintering, it is necessary to fatten and promote the growth of spinach, so that the leaves of spinach can quickly grow to about 5-6, which is more suitable for the stage of spinach wintering, when the resistance of spinach itself is very strong, and the area affected by the outside world is not very large. However, attention should be paid to the dosage and collocation when fertilizing, so as not to overgrow spinach and then freeze to death on a large scale!

2. Grass film protection

Grass film protection is divided into two kinds, one refers to forage mulching, the other refers to plastic film, both of which are determined by the actual situation of each place. If the local temperature is extremely low, and the moisture is too much, it is easy to freeze, then it is best to choose plastic film, so the heat preservation effect is better. If the local snow is more, and continuous snow weather is more, it is best to use forage as a film. We can also decide these two according to our own conditions. generally speaking, when the temperature is continuously low, we should begin to prepare for use, not too late.

3. Soil moisture control

When the surface temperature reaches below zero, it freezes, but this is not the case in the soil. Many people think that wetting the soil a little before the winter will cause the spinach to freeze. In fact, this is wrong. As long as the soil is not so wet that it is slippery, the soil will not freeze. Wetting the soil is also good for the temperature, because the groundwater basically does not freeze, they can keep the temperature in the soil from falling below zero, so that spinach can better survive the winter. Therefore, it is necessary to control the soil moisture before overwintering.

4. Prevent frost

The frost during the overwintering period is a disaster that has the greatest impact on spinach, some are caused by snow at the same time, some are caused by snow thawing during the day, and then freeze again at night, spinach faces this disaster, basically will lose a lot of money. In the face of such a situation, you can consider blocking the top of the spinach field with plastic sheeting, which can effectively reduce the loss of the disaster. Put the plastic sheet sideways and prepare a few more fixed points in case the wind blows away.

These are some of the problems that spinach should pay attention to when overwintering. Many times in winter, people can't deal with these problems in time, so it's best to prepare in advance and don't have to worry about it when winter comes.
