Fast propagation method of macadimia nut seedlings

Abstract

The invention discloses a fast propagation method of macadimia nut seedlings. The method comprises the steps of stock cultivation, wherein a macadimia nut germination accelerating device is used, themacadimia nut germination accelerating device comprises a cabinet and germination accelerating boxes, air outlets are formed in the top of the cabinet, multiple atomizing nozzles are arranged on the top of the cabinet, an air inlet is formed in the bottom of the cabinet, and multiple water discharging and ventilation parts for water circulation and ventilation are arranged on the bottom of each germination accelerating box; stock seedbed production, germination accelerating and sowing, stock raising, scion treatment, grafting and field planting, wherein wounds of scions and stocks need to be washed with a mixture of a snail extract, honey, a glucose injection and a normal saline solution before grafting. By means of the method, the growth speed and the grafting survival rate of the seedlings can be improved, so that fast propagation of the macadimia nut seedlings is achieved.

Description

Technical field [0001] The invention relates to the technical field of macadamia nut planting, in particular to a method for rapid propagation of macadamia seedlings. Background technique [0002] Macadamia nuts are the top of the four famous dried fruits in the world and have long been the best-selling dried fruit food in the international market. 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 is about 50,000 tons, the United States is about 40,000 tons, South Africa is 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 industrial development of nuts. The suitable grafting time for macadamia nuts under natural conditions is spring, but due to the rainy days in spring, the grafting time is limited, which s...

AI Technical Summary

Problems solved by technology

Under the natural conditions of macadamia, the suitable time for grafting is spring. However, due to the more rainy days in spring, the grafting time is limited, which seriously affects the scale of grafting and the number of nurseries. Therefore, the existing macadamia breeding methods are mostly carried out in summer, autumn and winter. Large-scale grafting, usually after germination into seedlings, transplanting the seedlings, and then grafting the seedlings, this method has a long seedling raising cycle, high seedling raising costs, and the grafting survival rate is lower than 50%
