In rural areas, what are the local methods for preventing frost and freeze of crops?

In rural areas, there are many ways to protect crops from frost. The main purpose is to prevent crops from stopping growth and development, frostbite or death due to the impact of frost in winter, and to reduce the risk of frost damage. We rural people have no choice but to take some anti-frost measures to solve the impact and losses on crops!

In our rural areas, the following are the ways to protect crops from frost in winter.

The first method is: use wild firewood, rice straw, straw, paddy, sawdust ash, and bran residue to cover the soil to keep it warm and moisturizing.

The method is to transplant the crops and cover them with a layer of 2 to 3cm of wild firewood, straw, straw, paddy, sawdust, ash, and bran residue between the vegetable spacing and row spacing. They slowly ferment themselves to keep warm and moisturizing. They can also increase the fertility of crops and help keep them warm through the winter.

The second method is: water the ground with salt water.

When frost occurs in winter, use 10:1 salt water every 3 to 5 days to irrigate crops, 10 pounds of water to 1 pound of salt, because the sodium chloride in the salt can not only prevent frost, It can also turn frost into fertilizer and water for irrigating the ground, which is more conducive to the growth and development of crops.

The third method is: spreading plant ash on crops can prevent frost.

The method is to sprinkle hay ash evenly on the crops when the temperature is relatively low in the morning and evening in winter and there is a lot of dew. The ash will automatically ferment when exposed to water and frost. The heat generated can not only prevent frost , and can also prevent and control pests and diseases.

The fourth method is to use groundwater to drip irrigation crops to prevent frost.

The method is to use groundwater to spray and drip irrigate crops. Because the temperature of groundwater in winter is higher than that of surface water, watering crops every 2 to 3 hours in the morning and evening can prevent frost and freeze. , melting frost.

The fifth method is: use mulching film to cover transplanting and planting.

The method is to cover the soil with mulching film when planting winter crops, and then drill holes in the mulching film to plant crops. This can prevent frost, which can damage the root system of crops and cause the death of crops. .

Method 6: If it is a transplanted tree or bamboo to prevent frost, use rice to wrap the tree tip, bamboo tip, or tie the bark with straw rope to prevent frost.
