Problems solved by technology

[0003] In order to improve the resistance of Hongye Plum, the method of grafting is usually used to propagate Hongye Plum seedlings. The traditional method of grafting and propagation of Hongye Plum is complicated. It is necessary to prepare seedlings as rootstocks, and then the buds of Hongye Plum can be grafted on the rootstock. The operation is complicated. The cultivation period is long, and at the same time, the scion cannot be effectively induced to combine with the rootstock, and the survival rate of the scion is low, which needs to be improved

Embodiment 1

[0019] A cold-resistant, salt-alkali-resistant, and highly adaptable method for breeding red-leaf plum seedlings, comprising the following steps:

[0020] S1: Seedbed preparation, deep plowing in the autumn of the previous year, the plowing depth is 25cm, every 667m 2 Apply 2000kg of decomposed organic manure, pour through frozen water, and deliquescence in winter to activate the soil, fertilize the soil, and kill overwintering pests. After the soil is cultivated in the early spring of the next year, plow it again, and the plowing depth is 15cm. Height 20cm, width 80cm, bed distance 20cm;

[0021] S2: rootstock preparation, select the strong annual branches of the top of the mountain peach plant that grows vigorously and are free of diseases and insect pests, and cut the branches into rootstocks with the same length. Make a slanted cut to expand the contact surface between the cut and the soil, which is conducive to the absorption of nutrients and water. Cut the upper part of...

Embodiment 2

[0026] A cold-resistant, salt-alkali-resistant, and highly adaptable method for breeding red-leaf plum seedlings, comprising the following steps:

[0027] S1: Seedbed preparation, deep plowing in the autumn of the previous year, the plowing depth is 30cm, every 667m 2 Apply 2000kg of decomposed organic manure, pour through frozen water, and deliquescence in winter to activate the soil, fertilize the soil, and kill overwintering pests. After the soil is cultivated in the early spring of the next year, plow it again, and the plowing depth is 20cm. Height 20cm, width 80cm, bed distance 20cm;

[0028] S2: rootstock preparation, select the annual strong branches of the mountain peach plant with vigorous growth and no damage by diseases and insect pests, and cut the branches into rootstocks with the same length. Make a slanted cut to expand the contact surface between the cut and the soil, which is conducive to the absorption of nutrients and water. Cut the upper part of the branch...

Embodiment 3

[0033] A cold-resistant, salt-alkali-resistant, and highly adaptable method for breeding red-leaf plum seedlings, comprising the following steps:

[0034] S1: Seedbed preparation, deep plowing in the autumn of the previous year, the plowing depth is 35cm, every 667m 2 Apply 2000kg of decomposed organic manure, pour through frozen water, and deliquescence in winter to activate the soil, fertilize the soil, and kill overwintering pests. After the soil is cultivated in the early spring of the next year, plow again to a depth of 35cm, and rake the bed. Height 20cm, width 80cm, bed distance 20cm;

[0035]S2: rootstock preparation, select the annual strong branches of the mountain peach plant with vigorous growth and no damage by diseases and insect pests, and cut the branches into rootstocks with the same length. The oblique opening is used to expand the contact surface between the cutting and the soil, which is conducive to the absorption of nutrients and water. The upper part of...

Abstract

The invention discloses a breeding method of prunus cerasifera seedlings with cold resistance, saline-alkaline tolerance and strong adaptability. The method includes the following steps: S1, seedbed preparation; S2, preparation of rootstocks; S3, preparation of scion; S4, grafting; S5, management after grafting. The method grafts the prunus cerasifera into prunus dacidiana, so that the cold resistance, saline-alkaline tolerance and adaptability of the prunus cerasifera are improved. Annual strong and robust branches on the upper portions of prunus cerasifera plants are directly selected asrootstocks, so that the production process of the rootstocks is greatly reduced, and the breeding efficiency of the prunus cerasifera is improved. The survival rate of rootstock cutting can be improved by means of a rooting agent, and the survival rate of scion grafting can be improved by adopting healing fluid for treatment.

Description

technical field [0001] The invention belongs to the technical field of nursery stock breeding, and in particular relates to a method for breeding red-leaf plum seedlings with high cold resistance, salt-alkali tolerance and strong adaptability. Background technique [0002] Purple leaf plum, alias: red leaf plum, Rosaceae Prunus is a deciduous small tree, up to 8 meters high, native to southwest Asia, and widely planted in North China and its south. The leaves are purplish red all the year round. It is a famous foliage tree species. It is suitable for solitary planting and group planting, and can set off the background. Especially the shiny purple leaves, among the green leaves, look like invincible flowers, forming a beautiful landscape in the green mountains and green waters. [0003] In order to improve the resistance of Hongye Plum, the method of grafting is usually used to propagate Hongye Plum seedlings. The traditional method of grafting and propagation of Hongye Plum...
