Problems solved by technology

[0003] The present invention aims at the existing problems: the cold resistance of cinnabar plum is relatively poor, and the reproduction and survival are generally low, which affects the popularization and planting of its varieties; wherein the seed breeding method generally adopts sowing in late autumn, the external temperature is low, the seed germination speed is slow, and long-term retention in The soil will cause seed mildew, and its poor cold resistance will eventually lead to an extremely low survival rate of cinnabar plum trees; and using adult cinnabar plum tree branches as scions or cutting branches cannot improve the cold resistance and environmental adaptability of cinnabar plum trees , there is also a low reproductive survival rate of cinnabar plums, and the cultivated cinnabar plums have poor adaptability, and daily management is time-consuming and laborious

Embodiment 1

[0020] A method for improving the cold resistance grafting cultivation of cinnabar plum, comprising the following steps:

[0021] (1) Seed preservation: immerse cinnabar plum and apricot plum seeds in potassium permanganate solution for sterilization, which can reduce the inhibitory effect of pathogenic bacteria metabolites on planting germination, and then mix with organic fertilizer and store at -4.5°C for 18 days , and use a 220lux ultraviolet lamp to irradiate for 3.5 hours a day, which can promote the production of mutant individuals adapted to low temperature, and improve the nutrient accumulation and stress resistance in the body, so that the seeds of cinnabar plum and apricot plum can be preserved;

[0022] (2) Mutagenesis: immerse the preserved cinnabar plum seeds in the nutrient solution for mutagenesis treatment. The nutrient solution contains vitamins, organic selenium and other ingredients that can protect the germ. First, set the temperature at 38°C for 14 minutes...

Embodiment 2

[0034] (1) Seed preservation: immerse cinnabar plum and apricot plum seeds in potassium permanganate solution for sterilization, which can reduce the inhibitory effect of pathogenic bacteria metabolites on planting germination, and then mix with organic fertilizer and store at -3.5°C for 19 days , and use a 230lux ultraviolet lamp for 4 hours a day, which can promote the production of mutant individuals adapted to low temperature, and improve the nutrient accumulation and stress resistance in the body. It is necessary to preserve the cinnabar plum seeds and apricot plum seeds;

[0035] (2) Mutagenesis: immerse the preserved cinnabar plum seeds in the nutrient solution for mutagenesis treatment. The nutrient solution contains vitamins, organic selenium and other ingredients that can protect the germ. First, set the temperature at 39°C for 15 minutes, and then Lower the temperature to -2°C and let stand for 24 minutes, and use 68 rem gamma rays to irradiate for 8 minutes / time at ...

Embodiment 1、 Embodiment 2

[0060] To embodiment 1, embodiment 2, contrast 1, contrast 2, contrast 3, contrast 4, contrast 5, contrast 6 and control group experimental scheme, statistics cinnabar plum cold-resistant temperature, survival rate, florescence time and variation rate

[0061] project

[0062] Comprehensive results: Compared with the control group, the cinnabar plum cultivated by the method of the present invention has a 9°C lower cold-resistant temperature, a 46.1% higher survival rate, a 9d longer flowering period, and a variation rate of more than 2.31%. Using ultraviolet lamps and mutagenesis treatment methods can reduce the cold-resistant temperature by 2°C and 5°C, increase the survival rate by 8.7% and 15.3%, and increase the mutation rate by 0.56% and 1.42%, and the mutagenesis treatment can prolong the flowering time by 4 days; As a rootstock, the cold-resistant temperature can be reduced by 2°C, the survival rate can be increased by 10.4%, and the flowering time can be exten...

Abstract

The invention discloses a grafting plantation method capable of improving the cold resistance of armeniaca mume var. mume f. purpurea. The grafting plantation method comprises the following aspects of: (1) seed preservation: seeds of armeniaca mume var. mume f. purpurea and armeniaca mume var. bungo Makino are soaked in a potassium permanganate solution for sterilization treatment, then the soakedseeds are mixed with organic fertilizer, and the obtained mixture is preserved at a low temperature and irradiated with a UV lamp every day; (2) mutation: the preserved seeds of armeniaca mume var. mume f. purpurea are soaked in a nutrient solution for mutagenic treatment and irradiated with gamma rays at a low temperature; (3) cultivation in a greenhouse: organic fertilizer and fine sand are added into soil, mixing is performed, and seedbed laying is conducted; the seeds of armeniaca mume var. mume f. purpurea and armeniaca mume var. bungo Makino after generation accelerating are mixed and sowed for temperature cultivation; (4) grafting: the upper parts of young seedlings of armeniaca mume var. mume f. purpurea are cut out as scions, inclined cutting is conducted on both sides of the lower part of each young seedling of armeniaca mume var. mume f. purpurea, and young seedlings of armeniaca mume var. bungo Makino are cut out as rootstocks, cutting is carried out at the middle parts ofthe young seedlings of armeniaca mume var. bungo Makino, a protective liquid coating is applied to the joint parts, and two layers of preservative films are used to wrap the joint parts; and (5) later-stage cultivation: grafted plants of armeniaca mume var. mume f. purpurea are placed in a cultivating pot for cultivation in a greenhouse, external adaptive cultivation is conducted for 30 days, andthen the grafted plants of prunus mume var bunqo are transplanted.

Description

technical field [0001] The invention belongs to the technical field of cinnabar plum cultivation, and in particular relates to a grafting cultivation method for improving the cold resistance of cinnabar plum. Background technique [0002] Cinnabar plum, which belongs to the dicotyledonous class Rosaceae ornamental plants, is a straight-legged plum variety in plum blossoms. The branches of cinnabar plum are straight or oblique, and there will be no distortion during growth. It is mainly distributed in East Asia, Central Asia, Asia Minor and In the Caucasus region; the flower color of cinnabar plum is light red, and its new xylem is light purple. It is called "bone red". It has bright colors and elegant fragrance, and has high ornamental value and economic value. Side or courtyard landscape setting, it is a precious variety among plum blossoms. Apricot plum has the characteristics of robust growth, strong cold resistance, and strong resistance to diseases and insect pests, an...
