Embodiment 1

[0017] A method for propagating macadamia nuts, comprising the steps of:

[0018] 1) Cultivation of rootstock seedlings: Cultivate seedlings with tree planting bags. After 800 rootstock seedlings of macadamia nuts are cultivated to more than 60cm, timely weeding, fertilization, insect removal, disease prevention, strengthening management and protection, and selection of rootstock seedlings with a stem diameter of 1.15cm as grafting use seedlings;

[0019] 2) Scion selection: The scion is the semi-lignified spring shoot of Macadamia 788, retaining one complete leaf, and cutting off all the remaining leaves;

[0020] 3) Grafting: The grafting time is selected to be carried out in the late February of 2012 spring. Before grafting, apply enough fertilizer to the rootstock half a month ago to prevent and control diseases and insect pests. Cut the rootstock at a distance of 10 cm and cut off the leaves near the interface. For rootstocks with similar thickness, cut off 2 nodes and k...

Embodiment 2

[0023] A method for propagating macadamia nuts, comprising the steps of:

[0024] 1) Cultivation of rootstock seedlings: Cultivate seedlings with tree-planting bags. After 800 rootstock seedlings of macadamia nuts are cultivated to more than 60cm, timely weeding, fertilization, insect removal, disease prevention, strengthening management and protection, and selecting rootstock seedlings with a stem diameter of 0.95cm as grafting use seedlings;

[0025] 2) Scion selection: The scion is the semi-lignified spring shoot of Macadamia 788, retaining one complete leaf, and cutting off all the remaining leaves;

[0026] 3) Grafting: Grafting time is selected to be carried out in the late February of 2013 spring. Before grafting, apply enough fertilizer to the rootstock half a month ago to prevent and control diseases and insect pests. Cut the rootstock at 12cm, and cut off the leaves near the interface. For rootstocks with similar thickness, cut off 2 nodes and keep 1 complete scion ...

Embodiment 3

[0029] A method for propagating macadamia nuts, comprising the steps of:

[0030] 1) Cultivation of rootstock seedlings: Cultivate seedlings with tree planting bags. After 800 rootstock seedlings of macadamia nuts are cultivated to more than 60cm, timely weeding, fertilization, insect removal, disease prevention, strengthen management and protection, and select rootstock seedlings with a stem diameter of 1.35cm as grafting use seedlings;

[0031] 2) Scion selection: The scion is the semi-lignified spring shoot of Macadamia 788, retaining one complete leaf, and cutting off all the remaining leaves;

[0032] 3) Grafting: Grafting time is selected to be carried out in the late February of 2014 spring. Before grafting, apply enough fertilizer to the rootstock half a month ago to prevent and control diseases and insect pests. Cut the rootstock at a distance of 15 cm and cut off the leaves near the interface. For rootstocks with similar thickness, cut off 2 nodes and keep 1 complet...

Abstract

The invention provides a propagation method of macadamia integrifolia. The propagation method comprises the following steps: (1), culturing rootstock seedlings: using tree planting bags for culturing seedlings, timely weeding, fertilizing, performing deinsectization, disease prevention and strengthening management and protection after the rootstock seedlings are cultured to be 60 cm or above, and selecting rootstock seedlings with the rootstock stem diameter of 0.95-1.35 cm as grafting seedlings; (2), selecting scions: the scions are semi-lignified spring twigs, retaining one intact leaf and shearing to remove the rest of leaves; (3), performing grafting: grafting is performed in late February during the spring, clipping lower half parts of the selected scions in the step 2 to achieve smooth wedge-shaped notches of 2-3 cm in length, longitudinally cutting centers of the notches of the rootstock to obtain grafting openings of 2.5-3 cm in length, inserting the scions with the wedge-shaped notches into the grafting openings for grafting; when the plants grow stably and new roots grow out of the plants, the plants can be transplanted out of a nursery; (4), performing field management: the plants that are transplanted out of the nursery are watered timely , weeds are killed, the fertilizer is applied and pest control is carried out. According to the propagation method of macadamia integrifolia, provided by the invention, rootstock seedlings, scions and the grafting method are optimally selected, so that the grafting survival percentage of macadamia integrifolia can reach 95% or above.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, and in particular relates to a macadamia nut propagation method. Background technique [0002] Macadamia is the first of the four famous dried fruits in the world, and has been the best-selling dried fruit food in the international market for a long time. It is predicted that by 2020, the world's total output of macadamia nut shells will be about 250,000 tons, of which the annual output of Australian macadamia nuts will be about 50,000 tons, the United States will be about 40,000 tons, South Africa will be about 20,000 tons, and my country's output will reach about 20,000 tons. . However, the current demand for macadamia nuts is more than 400,000 tons. This large demand provides a very broad market prospect for the industrialization of macadamia nuts. [0003] Most of the existing macadamia breeding methods are large-scale grafting in summer, autumn, and winter. Usually, after germination and ...
