Peach tree, a small deciduous tree in Rosaceae, is a small deciduous tree with fruit as its fruit. Flowers are visible, fruits are juicy, and can be eaten raw, pickled or canned, and nucleolus can also be eaten.

The flesh is white and yellow, and there are many varieties of peaches. Generally, the skin is hairy, the nectarine skin is smooth, the flat peach fruit is flat and disc-shaped, and the peach is an ornamental peach with various petals.

After peach trees enter natural dormancy, they need to experience a certain low temperature to get through dormancy, that is, to break dormancy. Otherwise, the germination is late, the development is poor and irregular, the flower buds do not open or fall off, and the roots and branches of peach trees sometimes grow synchronously and sometimes alternately, reflecting the transfer of nutrition distribution centers.

In spring, the roots begin to move at the earliest, providing necessary water, nutrition and hormones to promote cell division and growth. Before normal defoliation, the leaves of peach trees return and are stored in buds, branches, stems and roots, so it is of great significance to keep leaves in autumn for supporting roots, strengthening buds and enriching branches.

Morphological characteristics of peach

1, leaf

Young leaves are folded in half at bud stage, and then open when flowering, and open at the same time. There are often glands on petiole or leaf margin.

2. flowers
