Method for breeding new varieties of peach trees

Abstract

The invention discloses a method for breeding new varieties of peach trees. The method particularly includes the steps: (1) ridging a field and seeding on ridges; (2) watering and fertilizing sprouted seeds at regular intervals and performing conventional care; (3) taking new branch buds of Chinese birthday peaches as grafts after peach seedlings are bred for a year, grafting the new branch buds by taking the peach seedlings as tree stocks, cutting the grafts into blade shapes and inserting the grafts to wood portions of the tree stocks or joints of basts and the wood portions; (4) wrapping grafting ports with plastic films, exposing the grafts to breathe and removing the films after the grafts grow and survive; (5) uniformly laying a layer of grasses on the ridges and among the ridges with the growing peach seedlings when the field temperature is higher than 35 DEG C in the growing process of the tree stocks to prevent the peach seedlings from high-temperature burn; (6) cooling the peach trees before a flowering phase; and (7) watering and fertilizing the peach trees at regular intervals and performing conventional care. The new varieties bred by the method are superior to winter peaches growing in the north in terms of condition and quality, and the situation that peaches cannot grow in regions except for the north in late winter is improved.

Description

technical field [0001] The invention relates to agricultural technology, in particular to a method for cultivating new qualities of peach trees. Background technique [0002] At present, there are no peach tree varieties that can go on the market in winter in my country except the north. Consumers in regions other than the north must transport peaches from the north if they want to eat peaches in winter. Due to the long distance from the north to areas other than the north, especially from the north to the south, peaches are inevitably crushed and crumbled during transportation. Winter peaches transported to the south after long distances are often of different quality, which affects sales. In addition, the long-term transportation process takes a long time, and the winter peaches in the hands of the fruit grower to the transporter and then to the distributor are not fresh and have a poor taste. Therefore, there is often no market for winter peaches in the north in the sou...
