a) Seedling cultivation
Peach trees are usually propagated by grafting. Commonly used rootstocks are grafted, and nectarine is mostly used in southern China and western regions; in the north, there are more pecans; in others, apricots, plums and almonds are used as rootstocks. In recent years, for the purpose of dwarfing close planting, the use of wool cherries, prunus triloba, etc. as rootstocks has become more effective. Although the dwarfing effect is obvious, the performance varies across the country and needs further study. It is best to choose Taoyuan as a plot of land where there is plenty of sunshine, high dryness, deep soil, loose soil, plenty of water, and unobstructed drainage.
Peach rootstock grows vigorously, mostly in the spring sowing, autumn grafting, two years out of the garden. Seeds of rootstock go through 80 fingers and peaches before sowing.
Peach trees can be grafted in spring, summer and autumn. Branches or shoots can be used in the spring and shoots in the fall. If the rootstock has a suitable thickness, buds will be planted in advance in June, then the anvil can germinate quickly, and then the nursery can grow into a nursery. Buds should be selected as the result of the buds in the middle of the branch. Do not use single buds. The buds that survived in the fall were then used for patching by the grafting method.
(b) Planting
It is best to choose Taoyuan as a plot of land where there is plenty of sunshine, high dryness, deep soil, loose soil, plenty of water, and unobstructed drainage.
The planting density of peach trees depends on factors such as the type of rootstock, variety characteristics, topography, climate, soil, shaping, and management methods. General land can be planted at a spacing of 35 meters. However, in recent years, there has been a tendency to gradually reduce the planting distance. In particular, the use of dwarfing stocks can be appropriately reduced in planting distance in order to achieve the goal of premature delivery and premature harvest. At present, it is considered that the appropriate density of planting is 2.5 meters (Y. In short, what kind of density is the most favorable, it has yet to be tested in all aspects.
Peach trees belong to self-pollination fruit trees. Only a few female flower varieties and self-flowering varieties with low seed setting rate need to be equipped with pollinating trees. For example, Okubo, Orange Early Harvest, Qingfeng, Yanhong, and Sahua River Peach are all optional pollination varieties. The pollination variety should be similar to the flowering period of the main cultivar.
To prevent pests and diseases from the nursery, 4 degrees lime sulfur can be used to disinfect the roots of the seedlings before planting (wash with clean water after disinfection).
