With the onset of winter, the temperature drops, the leaves fall back to the roots, the nutrients return, the photosynthesis and absorption activities of the trees stop, the resistance decreases, and the trees in the dormant period lose the shade of the leaves, and the branches are exposed to nature. Among them, freezing and sunburn are prone to occur, weakening the tree's potential, affecting the annual output, and even causing tree death. Dormant trunk whitening not only can prevent sunburn and frost damage of fruit trees, but also eliminate a large number of pathogens and pests that overwinter on tree trunks. It is an important measure for pest control and tree protection in dormant fruit trees. The preparation ratio of the whitening agent is: 10 parts of quicklime, 2 parts of stone sulphur mixture, 1-2 parts of salt, 2 parts of clay, and 35-40 parts of water. It is best to use white for 2 times. The first time after defoliating the fruit trees until the soil is frozen, the second time is in early spring.
