Peach blossom originated in central and northern China and has a long cultivation history. Later, it gradually spread to the surrounding areas of Asia and spread from Persia to the west. Persica, a peach blossom, means Persia in Latin. China, French, Mediterranean, Australian and other warm regions. Its reproduction is mainly grafting.
Grafting is the main method of peach blossom propagation, and cuttage or shield bud grafting is commonly used. Peach (a semi-cultivated type of peach) is widely used as rootstock in East China, while apricot is used in North China. However, peach trees grafted with Prunus armeniaca or Prunus armeniaca rootstock have short tree age and many pests and diseases. If apricot is used as the rootstock, although the grafting is laborious and the initial growth is slightly slow, the life span is longer and there are fewer pests and diseases. Autumn sowing is convenient for rootstock seeds; Or sow in layers with wet sand after autumn, and take it out for sowing in early spring of the following year.
When sowing, the general row spacing is 40 ~ 50 cm, the plant spacing is 10 ~ 20 cm, and the furrow is 5 cm, with one grain for each place. When sowing in spring, if the buds have sprouted, cover them with soil. Bud grafting is mostly carried out in July and August. One-year-old seedlings are better as rootstocks, and two-year rootstocks are barely available. The survival rate of bud grafting is very high, mostly above 95%; Most of them didn't germinate that year, so they should be checked once in spring. Those who survive will remove the rootstock bud and let the peach blossom scion sprout, while those who don't survive can make up the bud and propagate immediately.
