Re-grafting repair method for macadamia nuts

Abstract

A re-grafting repair method of macadamia nuts comprises the steps of treatment of re-grafting points, treatment of re-grafted branches, selection of re-grafting time, re-grafting and application of a multi-point method and management and trimming after re-grafting. The re-grafting survival rate reaches 90% or above, and the fruit ripening time of the macadamia nuts can be one year ahead. By re-grafting original varieties or new varieties on branches, the purposes of replacing varieties and adding new branches are achieved, the centers of fruit trees can also be adjusted, the center of gravity can be lowered, adverse weathers such as typhoon can be resisted, the borne fruit quantity and the fruiting quantity can be increased, the variety repairing time can be shortened, the production can be quickly restored, trial production can be achieved in the second year after large repair, the original yield can be restored in the third year, the economic benefit loss can be reduced, and a great promoting role is played for increasing the economic benefits of agricultural farmers.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for multiple grafting and repairing macadamia nuts. Background technique [0002] Macadamia nuts, also known as Queensland chestnuts, macadamia walnuts, and macadamia nuts, are known as the "king of dried fruits" for their crispy, smooth, and delicious nuts with a unique buttery aroma. Macadamia nuts are rich in nutrients, with an oil content of 70%-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 macadamia nuts is 6.2 , protein 9%, also rich in calcium, phosphorus, iron, vitamin B1, B2 and 8 kinds of amino acids necessary for human body. Regular consumption of macadamia nuts can also regulate body cholesterol, lower blood pressure, control blood sugar levels, prevent tumors and some cancers, anti-aging, improve skin con...

Problems solved by technology

[0003] The branches of the macadamia tree are fragile. When planting macadamia nuts, the tree canopy is dense, the root system is shallow, and it is not wind-resistant. Therefore, the orchard should be located in a place with little wind all year round and in areas that are easily affected by typhoons. A windbreak forest belt should be built. Bamboo and tree branches are needed for support to resist wind damage; in reality, growers have suffered heavy losses from adult macadamia trees that were blown down by typhoons and caused large-scale fractures; once they are blown down, it is too late to replant them, The economic cost is very high, and it usually takes four years to breed new varieties, which seriously affects agricultural production; often due to unprofessional technology and over-pruning during planting, the macadamia nuts with too few adult branches have less fruit bearing in large seedlings, which affects income; There are still problems in the stage of macadamia planting, such as improper management, too high setting pole, resulting in late fruit bearing, missed fruit, or the variety has been planted for a long time, resulting in no fruit.
