Embodiment 1

[0021] A method for grafting and cultivating apple seedlings suitable for dwarfing middle stock apple seedlings in alpine regions is characterized in that it comprises the following three steps:

[0022] (1) Cultivate the seed anvil: in February of the first year, prepare the seeds of Vitex and carry out germination treatment. The method of germination treatment is: soak the seeds of Vitex with warm water at 28°C for 1 day, pull out the seeds and control them. Dry, then soak in 5 / 1000 potassium permanganate aqueous solution for 40-60 minutes, remove and dry, mix the seeds with 1.5 times the volume of river sand, keep the temperature of the river sand at 5°C, and the water content at 50%. After 25 days, adjust the river sand temperature to 18°C ​​for 5 days;

[0023] After the germination treatment, sow the seeds of Vitex chinensis in the greenhouse, control the temperature of the greenhouse to 18°C, the humidity to 40%, and the light intensity to 1800lx; mix the soil, river sa...

[0029]A method for grafting and cultivating apple seedlings suitable for dwarfing middle stock apple seedlings in alpine regions is characterized in that it comprises the following three steps:

[0030] (1) Cultivate the seed stock: prepare the seeds of Vitex japonica for germination treatment in February of the first year. The method for germination treatment is: soak the seeds of Vitex japonica with warm water at 30°C for 1.5 days, pull out the seeds and control them. Dry, then soak in 5 / 1000 potassium permanganate aqueous solution for 60 minutes, remove and dry, mix the seeds with 2 times the volume of river sand, keep the temperature of the river sand at 8°C, and the water content at 60%, after 30 days Adjust the river sand temperature to 20°C for 7 days;

[0031] After germination treatment, sow the seeds of Vitex chinensis in the greenhouse, control the temperature of the greenhouse to 25°C, the humidity is 50%, and the light intensity is 2200lx; mix the soil, river sand...

Embodiment 3

[0037] A method for grafting and cultivating apple seedlings suitable for dwarfing middle stock apple seedlings in alpine regions is characterized in that it comprises the following three steps:

[0038] (1) Cultivate the seed stock: in January of the first year, prepare the seeds of Vitex and carry out germination treatment. The method of germination treatment is: soak the seeds of Vitex with warm water at 29°C for 1.5 days, pull out the seeds and control them. Dry, then soak in 5 / 1000 potassium permanganate aqueous solution for 50 minutes, remove and dry, mix the seeds with 2 times the volume of river sand, keep the temperature of the river sand at 7°C, and the water content at 55%, after 28 days Adjust the river sand temperature to 19°C for 6 days;

[0039] After germination treatment, sow the seeds of Vitex chinensis in the greenhouse, control the temperature of the greenhouse to 22°C, the humidity to 45%, and the light intensity to 2000lx; mix the soil, river sand and hum...

Abstract

The invention discloses a grafting cultivation method suitable for dwarf interstock apple seedlings of apples in alpine regions belonging to the technical field of apple grafting cultivation. The method comprises the three steps of seedling rootstock cultivation, dwarf interstock grafting and bud grafting of cultivated varieties, and specifically comprises the following steps of preparing malus baccata seeds from January to February of the first year for germination accelerating treatment; sowing the malus baccata seeds in a greenhouse after germination accelerating treatment; after the malus baccata seeds germinate, screening out qualified malus baccata nursery stocks and transplanting outdoors; purchasing MM106 dwarfing rootstocks in September of the first year, grafting with malus baccata; and from August to September of the second year, selecting scions of a cultivated variety with the tree age of 4 to 6 years, treating the scions for 1 to 2 days, then grafting buds to dwarf interstock seedlings, and spraying a plant growth regulator after 10 to 15 days. The survival rate of the dwarf interstock apple seedlings obtained through the method in the alpine regions reaches 96 percent or above, and the seedling raising cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of grafting and cultivating apple seedlings, in particular to a method for grafting and cultivating apple seedlings suitable for dwarfing apple seedlings in alpine regions. Background technique [0002] Apple is a plant of the genus Malus in the subfamily Rosaceae, and its tree is a deciduous tree. Apples have high nutritional value, rich in minerals and vitamins, and rich in calcium, which helps to metabolize excess salt in the body. Malic acid can metabolize calories and prevent obesity in the lower body. China is a big apple producing country, accounting for 65% of the total apple production. [0003] Apple trees are temperate fruit trees that like low temperature and dryness. It is required that there is no severe cold in winter and no severe heat in summer. The suitable temperature range is the annual average temperature of 9-14°C, the extreme low temperature in winter is not lower than minus 12°C, an...
