Does frost affect vegetables? How to do a good job of frost prevention measures?

If the frost is light, the leaves will only turn yellow and white, and the vegetables can continue to grow after the cold protection in the later stage. In severe cases, the leaves will dry up and die, leading to the death of the whole plant. For some vegetables that have just sprouted or are in the seedling stage, the mortality rate of seedlings after frost is still quite high.

How to do a good job of frost prevention measures?

The first one: build an arched shed. This kind is the most common in my family. We all put bamboo in the ground to form an arch, then cover it with plastic film, and then press the plastic film around with broken soil, and a simple arch shed comes out, which is simple and economical. Generally, the air is released around 0: 00 am/kloc-0, and the tuyere is closed around 4 pm. The duration of the wind is determined by the weather. In this way, you will not be afraid of frost, and it is also good for some vegetables that need high temperature.

The second type: cover vegetables with straw, weeds and sugarcane leaves. For example, after the leek is harvested, it is generally enough to cultivate the soil or cover it with straw. Protect with straw, weeds, etc. Frost won't hurt it.

The third type: directly covered with large plastic film. In my home, they found it troublesome to make a small arch shed, so some people covered it with large plastic film and opened it the next day. In fact, this is also possible. I remember one year, my mother just built a large vegetable field with a large piece of plastic film to prevent vegetables from freezing to death.

Fourthly, quick-acting fertilizers can be properly added to vegetables that are not seriously damaged by frost, so that they can absorb nutrients, improve their cold resistance and restore their growth ability. At the same time, it is necessary to clean up the frozen plants to prevent the rot from spreading to other vegetables.

Fifth: always pay attention to the climate. Now the information network is very developed, and it is easy to understand the local climate. So we should pay close attention to the climate and take preventive measures at any time.

Sixthly, the vegetables to be picked should be picked in time before frost, so as to avoid the damage of frost to vegetables and reduce losses.

In a word, frost affects vegetables. For vegetable farmers, we should pay attention to the weather forecast in time. Keep plastic film, straw, weeds, etc. Always keep it at home, so that you can come in handy when you need it. The above is my personal opinion.
