Embodiment 1

[0015] Take the 6-year-old physiologically mature fruit of the H2 macadamia variety, remove the outer skin, soak it in water for 11 hours, let it germinate at room temperature (≥20°C), remove the floating shriveled and weak seeds, air-dry, repeat three times, and mature the grain size Seeds soaked in 1000 times 50% thiophanate-methyl solution for 3 minutes and then sowed on the sand bed to accelerate germination. When most of the seedlings’ first two rounds of leaves have stabilized and hardened, they are transplanted into nutrition bags for centralized management. The composition of nutrition bags is 1:1 by weight. The mixed fermented and decomposed chicken manure and soil, when the thickness of the rootstock for grafting is 0.8-1.0 cm (about 15 cm in diameter from the ground), grafting begins after reaching the test standard. .

[0016] Grafting was carried out in March, and the scion was Qiushao of Guire No. 1 variety, which grew vigorously, matured and plumped up, and had ...

Abstract

The invention provides a macadamia nut seedling cultivating method. The method is characterized in that H2 or OC macadamia nut variety seedlings are used as stock, the first Guire macadamia nut variety is used as scions, and the cleft grafting method is adopted for grafting; the seedling cultivating step comprises seedling planting, scion processing and management performed after grafting. According to the method, drought hardening is performed before stock seedling germination, phosphorus and potash fertilizer is reasonably applied to the grafted seedlings, nitrogenous fertilizer is properly controlled, the root system of seedlings is promoted to grow downwards, and plants are prevented from growing upwards, so that the root system is developed and deep rooted, the ratio of the root to the crown is large, the resistance is high, and the survival rate of transplanting is high.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation, in particular to a macadamia nut grafting and seedling cultivation technology. Background technique [0002] Macadamia nuts (Latin scientific name: Macadamia ternifolia F.Muell.) Alias: Queensland chestnut, macadamia walnut, macadamia nut, Queensland fruit. Macadamia nuts are rich in nutrients, with an oil content of 70% to 79%. They are especially rich in unsaturated fatty acids, mainly oleic acid and palmitic acid. The ratio of unsaturated fatty acids to saturated fatty acids in the kernels of light-shelled macadamia nuts is 6.2 , the rough shell species is 4.8; the protein is 9%, and it is also rich in calcium, phosphorus, iron, vitamin B1, B2 and 8 kinds of amino acids necessary for the human body. Macadamia nuts are crispy, smooth, tender and delicious, with a unique buttery aroma. They are the highest quality edible nuts in the world and are known as the "Queen of Dried ...
