According to the Central Weather Bureau, the winter of 2016 is in the state of La Nina, and this winter may be “frozen.” So cold winter, fruit trees will be very common cold. Apple trees are frozen, branches, flower buds and roots are obvious. Branches frozen, the appearance of no major changes, but the interior will become dark brown, causing serious black heart, germination late, leaf thin or deformed, growth is not normal, etc .; of which the twigs and branches of the angle vulnerable to frost damage. Flower bud frost damage manifested as internal scales brown, winter temperature is not stable, early spring flower buds after the end of dormant encounter the most susceptible to cold in winter, frostbite in early spring frost damage mainly pistils, the performance of death of the flower bud dry,
