Embodiment 1

[0025] A method for dwarfing macadamia nuts, comprising the following steps:

[0026] (1) Select the rootstock: Take macadamia seedlings with a growth time of 9 months and a stem diameter of 0.9 cm as the rootstock;

[0027] (2) Select grafted spikes: select a mother tree with a pure variety, a strong mother tree, high and stable yield, and no pests and diseases, and cut macadamia nut branches with a length of 8 cm and 2 axillary buds as grafted spikes;

[0028] (3) Pre-treatment of grafted spikes: Spray and moisturize the grafted spikes with sterile water at a temperature of 8°C, and then irradiate the grafted spikes with 0.1 Mev of gamma rays at a dose of 0.2KGy to obtain treated grafts Spike;

[0029] (4) Grafting: cut the rootstock at a distance of 22 cm from the ground with branch shears to form a rootstock incision, and then graft the treated grafted scion onto the rootstock incision to obtain macadamia grafted seedlings;

[0030] (5) Management of grafted macadamia se...

Embodiment 2

[0035] A method for dwarfing macadamia nuts, comprising the following steps:

[0036] (1) Select the rootstock: Take macadamia seedlings with a growth time of 11 months and a stem diameter of 1.1 cm as the rootstock;

[0037] (2) Select grafted spikes: select a mother tree with a pure variety, a strong mother tree, high and stable yield, and no pests and diseases, and cut macadamia nut branches with a length of 12cm and 4 axillary buds as grafted spikes;

[0038] (3) Pre-treatment of grafted spikes: Spray and moisturize the grafted spikes with sterile water at a temperature of 12°C, and then irradiate the grafted spikes with 0.4 Mev of gamma rays at a dose of 0.4KGy to obtain treated grafts Spike;

[0039] (4) Grafting: cut the rootstock at a distance of 26 cm from the ground with branch scissors to form an incision on the rootstock, and then graft the treated grafted scion onto the incision on the rootstock to obtain macadamia grafted seedlings;

[0040] (5) Management of g...

Embodiment 3

[0045] A method for dwarfing macadamia nuts, comprising the following steps:

[0046] (1) Select the rootstock: Take macadamia seedlings with a growth time of 10 months and a stem diameter of 1.0 cm as the rootstock;

[0047] (2) Select grafted spikes: select a mother tree with a pure variety, strong mother tree, high and stable yield, and no pests and diseases, and cut macadamia nut branches with a length of 9 cm and 3 axillary buds as grafted spikes;

[0048] (3) Pre-treatment of grafted spikes: Spray and moisturize the grafted spikes with sterile water at a temperature of 10°C, and then irradiate the grafted spikes with 0.3 Mev gamma rays at a dose of 0.3KGy to obtain treated grafts Spike;

[0049] (4) Grafting: cutting the rootstock at a distance of 24 cm from the ground with branch shears to form a rootstock incision, and then grafting the treated grafted scion onto the rootstock incision to obtain macadamia grafted seedlings;

Abstract

The invention discloses a macadamia nut dwarfing method. The grafted scion woods are sprayed and moisturized with low-temperature sterile water before the grafted scion woods are irradiated by the gamma rays, the grafted scion woods can be prevented from withering, and the grafting survival rate is increased; the illumination intensity of the macadamia nut grafted seedling in the daytime is properly weakened, and the light of the macadamia nut grafted seedling is increased at night, so that the rhizomes of the macadamia nut grafted seedlings are thickened, and meanwhile, the transverse growthrate of the tree bodies is accelerated; konjac glucomannan can be added into the root treating agent, so that the soil penetration depth of the macadamia tree root system can be increased, sufficientnutrients are improved for macadamia nut trees, and the premature senility of the macadamia nut trees can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for dwarfing macadamia nuts. Background technique [0002] Macadamia nut, also known as macadamia nut (summer fruit), is an emerging fruit tree in the world today. It is favored by consumers because of its excellent nutritional properties and flavor quality. It is expensive and enjoys the reputation of "Queen of Dried Fruits". The planting area of ​​macadamias in my country is about 1.2 million mu, mainly distributed in Guangxi, Yunnan, Sichuan, Guangdong and other subtropical regions without typhoon hazards. The macadamia tree grows vigorously and can grow all year round. If left unattended, there will be too many branches, clustered branches, broom branches, and messy structure, which will affect the ventilation and light transmission of the fruit tree, resulting in poor tree growth and greatly weakening the tree. The wind resistance and lodging resistan...
