Effects of Frost on Crops

The effects of frost on crops include providing water for crops, increasing pests and diseases, improving fruit quality, delaying crop growth and reducing crop yield.

1, providing water for crops.

There is little precipitation in winter, and many crops grow in dry natural environment for a long time. If frost falls in extreme drought, when the sun comes out, the frost will melt into water and be directly absorbed by the leaves of crops, and the water dripping in the soil will also be used by crops, which can promote the growth of crops.

2. Pests and diseases have intensified.

Frost can also lead to an increase in pests and diseases. Frost weather will damage plants and make them more vulnerable to pests and diseases. Pests and diseases are important factors in agricultural production, and a large number of pests and diseases will lead to a significant reduction in crop yield.

3. Improve the quality of fruit.

Frost is a cold temperature, forcing crops to collect sugar to improve their energy against cold. At this time, the fruit will become sweeter and taste better, the edible value and commodity value will be improved to a certain extent, and the income of growers will also be improved.

The growth of crops is behind.

Frost has a direct impact on the growth of crops, which will cause the leaves or roots of crops to suffer freezing damage, leading to crop growth inhibition, growth lag and even death. Some special crops such as fruit trees and vegetables in tropical or subtropical areas are more obviously affected by this.

5. Crop yield reduction

When the frost damage is serious, crops are often frozen, which will not only cause different degrees of damage, but also cause a series of freeze injury symptoms such as withering and water loss. Large-scale frost is harmful to crop growth, especially planting production, which directly leads to serious crop yield reduction.
