Embodiment 1

[0022] This embodiment provides a method for grafting macadamia nuts, the steps are as follows:

[0023] S1. Seed treatment: the seeds are first sterilized with mercuric chloride solution, then alcohol, and then frozen at -20 to -18°C for 30 days, and the frozen seeds are kept at 4°C for 5 days;

[0024] S2, rootstock culture: put the treated seeds at room temperature for 8 hours, then soak them in water at 50-60°C for 24 hours, put the seeds in a sandy soil tray, and place them in a constant temperature incubator at 28-30°C to accelerate germination. After the crack, sow the seed crack downwards into the seedling cup, water thoroughly, put the seedling cup into a greenhouse for cultivation, and cultivate until the stem is 0.3-0.5 cm thick as a rootstock;

[0025] S3, scion cultivation: select two to three-year-old seedlings of good macadamia nuts as the female parent of the scion, cut off the top bud of the main branch, and promote the germination of the axillary bud; Apply ...

Embodiment 2

[0031] This embodiment provides a method for grafting macadamia nuts, the steps are as follows:

[0032] S1. Seed treatment: The seeds are first sterilized with mercuric chloride solution, then alcohol, and then frozen at -20 to -18°C for 28 days, and the frozen seeds are kept at 4°C for 6 days;

[0033] S2. Rootstock cultivation: put the treated seeds at room temperature for 10 hours, then soak them in water at 50-60°C for 24 hours, put the seeds in a sand tray, and place them in a constant temperature incubator at 28-30°C to accelerate germination. After the crack, sow the seed crack downwards into the seedling cup, water thoroughly, put the seedling cup into a greenhouse for cultivation, and cultivate until the stem is 0.3-0.5 cm thick as a rootstock;

[0034] S3, scion cultivation: select two to three-year-old seedlings of good macadamia nuts as the female parent of the scion, cut off the top bud of the main branch, and promote the germination of the axillary bud; Apply o...

Embodiment 3

[0040] This embodiment provides a method for grafting macadamia nuts, the steps are as follows:

[0041] S1. Seed treatment: the seeds are first sterilized with mercuric chloride solution, then alcohol, and then frozen at -20 to -18°C for 20 days, and the frozen seeds are kept at 4°C for 6 days;

[0042] S2. Rootstock cultivation: put the treated seeds at room temperature for 9 hours, then soak them in water at 50-60°C for 30 hours, put the seeds in a sand tray, and place them in a constant temperature incubator at 28-30°C for germination. After the crack, sow the seed crack downwards into the seedling cup, water thoroughly, put the seedling cup into a greenhouse for cultivation, and cultivate until the stem is 0.3-0.5 cm thick as a rootstock;

[0043] S3, scion cultivation: select two to three-year-old seedlings of good macadamia nuts as the female parent of the scion, cut off the top bud of the main branch, and promote the germination of the axillary bud; Apply once a day, ...

Abstract

The invention belongs to the technical field of grafting, in particular relates to a method of grafting macadamia nut. The method comprises the steps of S1, seed treatment, S2, stock culture, S3, scion cultivation, S4, grafting, and S5, management after grafting. The macadamia seeds are treated at a low temperature before sowing, when the seeds germinate and grow to 0.3-0.5 centimeter in stem length, they are used as the rootstock, the non-lignified branches produced by the grown grafted female parent are used as the grafted rootstock, in the grafting process, the rootstock and the scion are treated using a plant growth regulator, after the grafting process, the temperature and humidity are controlled, and fertilizer is applied, the grafting survival rate of the macadamia nuts is improved; when the seeds germinate and grow to 0.3-0. 5 centimeter in stem length, they are used as the rootstock, then grafted, and when they survive after the grafting process, the seedling rearing step is directly conducted, and the time used for seedling rearing is shortened.

Description

technical field [0001] The invention belongs to the technical field of grafting, and in particular relates to a method for grafting macadamia nuts. Background technique [0002] Macadamia ternifolia F.Muell is a plant of the genus Macadamia of the family Longanaceae, native to the subtropical rainforests of Queensland and New South Wales, Australia. It was introduced to Hawaii by Americans in the 19th century. In the 1920s and 1930s It was only domesticated and became an economically cultivated fruit tree, and it was introduced into China for trial planting in the 1960s and 1970s. Due to its high economic value, the world has developed rapidly in recent years. At present, it is planted in Guangdong, Guangxi, Yunnan, Fujian, Sichuan, Guizhou and Chongqing in China. [0003] Macadamia nuts are generally propagated by grafting. The traditional grafting technique for breeding macadamia seedlings has a low survival rate of only 15-50%. [0004] The application publication dat...
