Problems solved by technology

Although the above two methods can improve the survival rate, the operator must complete the grafting work in a short time, otherwise the survival rate will be low
The above-mentioned methods to improve the survival rate vary from person to person, and the proficiency of the operator is very strict, and the same person may also have poor reproducibility

Embodiment 1

[0025] The macadamia nut breeding method comprises the steps of:

[0026] (1) Seed treatment: The seeds harvested in the same year should be sown within one month of harvesting, and the large and robust seeds should be soaked in 1000~1200 times 70% thiophanate-methyl liquid for 15~20 minutes to disinfect them. sick.

[0027] (2) Sowing: Sow the sterilized and disease-free seeds on the germination sand bed. The ventral suture of the seeds should face down, the hilum and the germination hole should be on the same level, and the seeds should be separated by 1-2 cm. It is advisable to show the back slightly.

[0028] After sowing, the germination bed should be shaded with a sunshade net with 50% to 70% shading. Pay attention to frequent watering and keep the soil of the seedbed moist, especially within 1 week after sowing. In order to promote the smooth cracking of the seeds, it is necessary to ensure that the seeds have sufficient moisture. At the same time, special attention ...

Embodiment 2

[0040] The macadamia nut breeding method comprises the steps of:

[0041] (1) Seed treatment: The seeds harvested in the previous year should be soaked in clean water for 1 to 2 days before sowing, to remove floating shriveled and weak seeds, and to pick out moldy and bad seeds; The healthy seeds are soaked in 1200~1500 times 70% thiophanate-methyl medicinal solution for 10~15 minutes to disinfect and eliminate the disease.

[0042] (2) Sowing: Sow the sterilized and disease-free seeds on the germination sand bed. The ventral suture of the seeds should face down, the hilum and the germination hole should be on the same level, and the seeds should be separated by 1-2 cm. After sowing, cover with thin sand to prevent It is advisable to show the back slightly.

[0043] After sowing, the germination bed should be shaded with a sunshade net with 50% to 70% shading. Pay attention to frequent watering and keep the soil of the seedbed moist, especially within 1 week after sowing. In ...

Embodiment 3

[0055] The macadamia nut breeding method comprises the steps of:

[0056] (1) Seed treatment: Seeds harvested in the same year should be sown within one month of harvesting, and the large and robust seeds should be soaked in 1100~1300 times 70% thiophanate-methyl liquid for 15~20 minutes to disinfect them. sick.

[0057] (2) Sowing: Sow the sterilized and disease-free seeds on the germination sand bed. The ventral suture of the seeds should face down, the hilum and the germination hole should be on the same level, and the seeds should be separated by 1-2 cm. After sowing, cover with thin sand to prevent It is advisable to show the back slightly.

Abstract

The invention discloses a cultivating method for macadamia nuts. The cultivating method includes the steps of seed processing, seeding, seedling transplanting and grafting. The grafting further includes the steps of preparing before grafting, branch grafting and managing after grafting. Particularly, before grafting, people smear an aqueous surfactant solution on wounds of a scion and a rootstock, wherein the weight concentration of the aqueous surfactant solution is 0.5%o-1%. Due to the fact that people smear the surfactant solution on the surfaces of the wounds of the scion and the rootstock, the defect that gum flowing out of the wounds forms an isolation layer between scion and the rootstock can be overcome, permeability of body fluid between the scion and the rootstock is enhanced under the permeation action of the surfactant solution, the surfactant solution plays a role in sterilization and disinfection on the wounds, the survival rate of grafted seedlings is increased, and operation difficulty of grafting is lowered.

Description

technical field [0001] The invention relates to a macadamia nut breeding method and belongs to the field of agricultural planting. Background technique [0002] Macadamia is an evergreen tree or shrub of the family Longanaceae. It is also known as Queensland chestnut, macadamia walnut, macadamia nut, and Queensland fruit. The Latin name is Macadamia ternifolia F. Muell. Macadamia nuts have the highest economic value and have always enjoyed the reputation of "the king of dried fruits". It takes 8 to 10 years for macadamia seedlings to bear fruit after planting, but it takes 3 to 4 years for grafted seedlings to bear fruit. Therefore, the method of grafting seedlings is often used to cultivate macadamia nuts. The grafting survival rate of macadamia nuts is relatively low. The reasons are as described by Zhang Xiannu in "Factors and Countermeasures Affecting Grafting Survival Rates of Macadamia Nuts": 1. There is repulsion on the contact surface of grafting and healing wounds ...
