Abstract

The invention provides a quick cultivating method of macadamia integrifolia grafting seedlings. The quick cultivating method comprises the steps of selecting one-year-old seeds which are mature from the last ten-day period of September to the first ten-day period of October, of which the diameter is greater than or equal to 2.5cm and which reach physiological maturity for seedling culture; performing sowing in time at the middle ten-day period of the October, cultivating sand bed plantlets, and after 2 euphyllas of the seedlings are aged, performing transplanting in December; at the last ten-day period of the October next year, using the seedlings of which the height reaches 1.2-1.5m and the trunk middle part diameter reaches 1.5cm as root stock grafting seedlings; using scions after 45-60d of band girdle; if many buds are germinated, gradually screening robust 1-2 buds for growth, and erasing the other buds; and after branches and leaves are aged twice, performing coming out of the nursery. Through the adoption of the quick cultivating method disclosed by the invention, the cultivating cycle of the macadamia integrifolia grafting seedlings can be shortened, and quick cultivation of the macadamia integrifolia grafting seedlings can be completed within about 18 months.

Description
