The temperature is very low at night in winter, but during the day, as the temperature rises and the bark of the trees is dark brown, which easily absorbs light and heat, the temperature will rise very quickly. Such a large temperature difference will make trees susceptible to frost cracking. Apply lime water, because it is white, it can reflect 40% to 70% of sunlight, reducing the temperature difference between the day and night of the trees, so that they will not crack easily.

Finally, in agriculture, lime can also Mixed with copper sulfate to produce the famous pesticide "Bodor's solution", it is a powerful bactericidal pesticide, which can be said to be very useful in protecting plants.
