1、 It has the function of sterilization and insecticidal; Reduce pests and diseases in spring

The main function of lime water is to kill insects and sterilize and protect trees from being bitten by pests and bacteria during dormancy. In early winter, insects like to lay eggs in the cracks of the old tree bark, which puts the trees at risk. Brushing lime water can kill these pests and make their "overwintering" plan fail, so as to greatly reduce the harm of pests and diseases in spring and make the trees vibrant and full of spring in spring

2、 Prevent pests from climbing trees; Prevent bark from being bitten by animals

Pests prefer dark, dark and dirty places rather than white and clean places. Therefore, the white of lime water will make them "flinch", and the pests in the soil dare not climb onto the trees to harm and gnaw on the trees, so as to ensure the safety of the trees. The small animals on the roadside also like to grind their teeth and play in the trees, and this layer of lime can also play a certain protective role, so that the trees will not suffer too much trauma

3、 Antifreeze and thermal insulation; Reduce the large temperature difference between day and night

We should know that winter is very cold. We humans will wear thick down jackets to keep out the cold. Then the lime water is equivalent to the "down jacket" of trees. When the lime water is dry, it can keep the trees warm and let them spend the winter safely. In winter, the temperature is very low at night, but during the day, due to the increase of temperature, and the skin of trees is dark brown, it is easy to absorb light and heat, and the temperature will rise quickly. Such a large temperature difference will make trees easy to crack. Apply the lime water. Because it is white, it can reflect 40% to 70% of the sunlight, so as to reduce the temperature difference between day and night and prevent the trees from cracking easily

Finally, in agriculture, lime can also be mixed with copper sulfate to produce the famous pesticide "bodol liquid". It is a powerful bactericidal pesticide, which is very useful and escorts the plants
