A: Peach trees can be considered cold for trunk whitening, white trunks to prevent frostbite, frost, smoking, sunburn. The seedlings can be bagged in addition to the trunks. The preparation method and application method of the whitening agent are as follows: quicklime, lime sulfur, salt, grease (any animal or vegetable oil), clay, and water, and the trunk is painted white after being uniformly mixed. The white coated parts are mainly the base of the trunk (the height is 0.6-0.8m is appropriate) and the lower part of the main branch of the fruit tree, and the conditions can be properly coated to increase the height, so the effect is better. The whitening is carried out twice a year, after defoliation and in early spring. The whitening time in early spring is based on the premise that no ice is formed before drying after coating. The sooner the better, the newly planted trees should be painted immediately after planting.
