Embodiment 1

[0025] Example 1 : rootstock germination test

[0026] 1.1 Test treatment

[0027] Seeds of cherry cherry in Guangxi were selected, soaked with different concentrations of gibberellin, and then stratified at low temperature to investigate the germination rate, the number of lateral roots and the root length.

[0028] 1.2 Test method

[0029] The wild cherry seeds are divided into 5 groups, each group has 100 seeds, the first 4 groups are soaked with 0mg / L (clear water), 100mg / L, 200mg / L, and 300mg / L gibberellin for 24 hours, and the last group is CK (dried without treatment) as a control, then placed in a 4°C environment for low-temperature stratification for 40 days, and then placed at room temperature to allow it to germinate completely. Germination rate, number of lateral roots and root length were counted.

[0030] 1.3 Test Management

[0031] routine management.

[0032] Table 1 rootstock germination test

[0033]

[0034] It can be seen from Table 1 that the ro...

Embodiment 2

[0035] Example 2 : affinity test

[0036] 2.1 Test treatment

[0037] Four varieties of Meizao, Tourella, Brooks and Labins were selected for internal grafting and cultivation, and the survival rate of grafting and the degree of size of feet were investigated.

[0038] 2.2 Test method

[0039] Sow the rootstock seeds of the wild species of Chinese cherry-Cherry cerevisiae in Guangxi, and bud graft when the thickness of the rootstock reaches 0.75cm.

[0040] 2.3 Test Management

[0041] routine management.

[0042] Table 2 Grafting affinity test

[0043]

[0044]

[0045] It can be known from Table 2 that the grafted survival rate of rootstocks of Guangxi cherry blossoms is above 86%, indicating that the rootstocks have good affinity, and the grafted seedlings grow well.

Embodiment 3

[0047] A method for breeding and cultivating cherry seedlings suitable for being planted in the alpine mountainous area of ​​Guangxi, comprising the steps of:

[0048] (1) Collection and processing of rootstock seeds: at the end of April to the beginning of May, use the rootstock as the mother tree for seed collection. After picking the fruit, immediately put it into clean water and scrub it to remove the pulp, remove the fruit stems, remove the seeds, and dry them in the air; The rootstock is Guangxi wild cherry;

[0049] (2) Pre-germination in low-temperature sand storage: After passing the fine river sand through a 1mm sieve, soak and wash it twice with boiling water, and then dry it. After mixing the sand, put it on a tray or a seedling tray and cultivate it at a low temperature of 4°C for 35 days, keep the water, and pay attention to frost in the early stage; after 40 days, put it at room temperature to germinate; the specific operation of the low-temperature sand storage...

Abstract

The invention relates to the technical field of cherry cultivation, in particular to a propagation and breeding method of cherry seedlings suitable for being planted in a Guangxi cold highland area. The propagation and breeding method of the cherry seedlings suitable for being planted in the Guangxi cold highland area comprises the following steps of (1) collection and treatment of stock seeds, (2) low-temperature sand storage and germination accelerating, (3) seedling hardening, (4) selection of seedling growing land and leveling of the land, (5) transplanting of buds to the seedling growingland and management and (6) grafting and transplanting. According to the propagation and breeding method, a Chinese cherry wild species, namely Guangxi mountain cherries which locally grow in Guangxiare regarded as stocks for cultivation, and through seedling sowing, the stocks are used as grafting stocks of cherries of ultra-short low-temperature species and short low-temperature species. According to tests, seedlings obtained through germination accelerating and seedling growing on seeds of the Guangxi mountain cherries grow quickly, grafting can be conducted in the same year, and nursery stocks obtained after grafting of the stocks grow well, have good scion healing performance, are naturally dwarfed, bear fruits early, and are suitable for climate and soil of the Guangxi highland area.

Description

technical field [0001] The invention relates to the technical field of cherry cultivation, in particular to a method for breeding and cultivating cherry seedlings suitable for planting in the alpine mountainous area of ​​Guangxi. Background technique [0002] Cherry is the Chinese name for Acirola cherry. It is native to tropical America, West Indies, and the Caribbean, so it is also called West Indian cherry. Sweet cherry is also one of the earliest mature tree species among deciduous fruit trees. It is known as "the first fruit in early spring". All fresh cherry varieties with commercial value have been praised as a treasure among fruits. The current market is in short supply and has high economic value. [0003] Cherry fruit is bright in color, crystal clear and beautiful, soft and delicious, rich in nutrition, sweet and sour, etc., and has extremely high commercial value. At present, most of the commercial cherries in Guangxi and even South China are imported from abro...
