Embodiment 1

[0016] A method for grafting and propagating red plums utilizing green plums as stock, comprising the steps of:

[0017] (1) Pretreatment of greengage rootstock: In order to increase the survival rate of the trees after grafting, the selection season is at the beginning of September, and the greengage tree with a diameter of 20 cm is selected, and the upper part of the greengage tree to be grafted is cut off at a distance of 4 cm from the ground 10 days before grafting 2 days before grafting, the rootstock is watered and the section is sterilized. In order to promote the healing growth of the rootstock section and the scion after grafting, add 10% naphthalene acetic acid with a concentration of 250ppm in the common plant healing agent to smear the section to make rootstock to be used;

[0018] (2) Acquisition and processing of scions: collect annual-year-old robust branches without diseases and insect pests from mature mother trees suitable for local cultivation. The branches ...

Embodiment 2

[0022] A method for grafting and propagating red plums utilizing green plums as stock, comprising the steps of:

[0023] (1) Pretreatment of greengage rootstock: In order to increase the survival rate of the trees after grafting, the selection season is at the beginning of October, and the greengage tree with a diameter of 40 cm is selected, and the upper part of the greengage tree to be grafted is cut off at a distance of 6 cm from the ground 15 days before grafting 4 days before grafting, the rootstock was watered and the section was sterilized. In order to promote the healing growth of the rootstock section and the scion after grafting, 20% naphthalene acetic acid with a concentration of 250ppm was added to the common plant healing agent to smear the section. rootstock to be used;

Embodiment 3

[0028] A method for grafting and propagating red plums utilizing green plums as stock, comprising the steps of:

[0029] (1) Pretreatment of greengage rootstock: In order to increase the survival rate of the trees after grafting, the selection season is at the beginning of November, and the greengage tree with a diameter of 30 cm is selected, and the upper part of the greengage tree to be grafted is cut off at a distance of 5 cm from the ground 12 days before grafting 3 days before grafting, the rootstock is watered and the section is sterilized. In order to promote the healing growth of the rootstock section and the scion after grafting, add 15% naphthalene acetic acid with a concentration of 250ppm in the common plant healing agent to smear the section to make rootstock to be used;

Abstract

The invention discloses a red plum graft propagation method by using green plums as rootstocks. The red plum graft propagation method includes: selecting the green plums which are low in price, abundant in output and usually taken as waste by farmers as the rootstocks, subjecting the green plum rootstocks to pretreatment, scion treatment and grafting, and managing nutrient and water in later stages. By the aid of the red plum graft propagation method, perfect combination between the rootstocks and scions during graft propagation operation is guaranteed, survival rate of trees is increased while life time of the trees is prolonged by the aid of the pretreatment of the rootstocks and the scions, fertilizer efficiency of red plums is guaranteed to be sufficient rather than excessive by the aid of nutrient and water management in different periods in the later stages, growth cycle of red plum trees is shortened, growing quality and blooming quality of the trees are guaranteed, and disease resistance of plants is strengthened.

Description

technical field [0001] The invention relates to tree cultivation techniques, in particular to a method for grafting and propagating red plums using green plums as rootstocks. Background technique [0002] Red plum, small deciduous tree, Rosaceae, Prunus, plant height is about 10m, the stem is brownish purple, the flower is red or light pink, fragrant, with 5 petals, it has high ornamental value, and its growth cycle is long , so the price of red plum trees is also relatively high. At present, there are methods of grafting and propagating tree species such as peaches, plums, and apricots as rootstocks, but they have weak stress resistance, short lifespan, slow growth or low survival rate or There are problems such as high grafting costs, while the growth cycle of green plums is half shorter than that of red plums, and the price is lower. Rootstock resources for grafting. Contents of the invention [0003] Purpose of the invention: In order to solve the problems of short l...
