Embodiment 1

[0017] (1) Firstly, the propagated Chinese cherry was used as the base stock, and in the fall of that year, the imported Hungarian large cherry dwarf intermediate stock Mahally No. .

[0018] (2) In the spring of the second year, cut the anvil at 2 cm above the joint between the middle stock and the base stock, and untie the budding rope, and wipe off the new sprouts on the base stock at any time; The anvil is 10cm away from the grafting interface, and then the method of wood budding or square budding is used to graft the fine variety of large cherry variety Zao Daguo. The middle stock needs to be cut 2cm above the grafted large cherry variety, which has cultivated a dwarf middle stock. The survival rate of cherry seedlings is over 90%.

[0019] (3) In the winter of the third year or the spring of the fourth year, the dwarfing and close planting cultivation in the greenhouse is carried out, and the dwarfing middle stock that has been cultivated is planted with a row spacing o...

Embodiment 2

[0021] (1) Sow the Mahally cherry seeds at first, take the grown Mahally cherry seedlings as the base stock, and in the autumn of that year, graft the introduced Hungarian large cherry dwarf intermediate stock Mahally 2 with the method of wood budding or square budding No., grafted on the base anvil 20cm from the ground.

[0022] (2) In the spring of the second year, cut the anvil at 2 cm above the joint between the middle stock and the base stock, and untie the budding rope, and wipe off the new sprouts on the base stock at any time; The anvil is 12 cm away from the grafting interface, and then the method of wood budding or square budding is used to graft the fine variety of large cherry variety Hongdeng. The middle anvil needs to be cut 2 cm above the grafted large cherry variety, which has cultivated a dwarf middle anvil. The survival rate of cherry seedlings is 90%.

[0023] (3) In the winter of the third year or the spring of the fourth year, the dwarfing and close plant...

Abstract

The invention provides a method for densely cultivating dwarf interstock big cherry tress in a protected area. The method comprises the following steps that 1, selecting stocks, introduced big cherry dwarf interstocks are grafted to rootstocks; 2, dwarf interstock big cherry seedlings are cultivated; 3, dwarf interstock big cherry seedlings are densely planted. By the adoption of the method, the densely cultivated dwarf interstock big cherry trees are free of root knots, dry rot and other quarantine disease and insect pests, tree forms can be formed within two years, the trees can bear fruits within two years, the dwarf interstock big cherry tress bear fruits 2-3 years earlier than dwarf big cherry trees cultivated according to an existing dense cultivation method, the fruits come into the market earlier, the yield and quality of the big cherries are improved, high economic benefits are achieved, greenhouse cultivation and potted cultivation become possible, and the big cherry trees in the protected area have a bigger development space.

Description

technical field [0001] The invention relates to a method for densely planting large cherries in protected areas, in particular to a method for densely planting large cherries with dwarfed middle stocks in protected areas. Background technique [0002] Cherry (Cherry) is Rosaceae (Rosaceae), Prunus (Prunus), cherry subgenus (Cerasus) arbor-type fruit trees, its cherry tree body is tall, not suitable for growing in greenhouses, natural growth enters the fruiting period late, it takes 5 It takes ~6 years to bear fruit, and it takes 8 years to enter the high-yield period. The investment return period is long, and the management cost is high, which seriously limits the development of large cherries in protected areas. [0003] Dwarfing and dense planting usually refers to a cultivation method that uses biological and cultural methods to make the tree short, the crown compact, and convenient for dense planting. Nowadays, the dwarfing and dense planting of fruit trees has become an...
