AI Technical Summary

Technical Problem

In macadamia nut cultivation, mistletoe plants invade the phloem and xylem of the plant through their suckers, causing the loss of water, minerals and nutrients, mechanical damage to the tissue structure, and interference with the synthesis and transport of endogenous hormones, resulting in tree decline and reduced fruiting capacity, and in severe cases, the death of the entire plant.

Method used

By pruning diseased branches, spraying preventative pesticides, and supplementing with biological agents, organic fertilizers, high-potassium compound fertilizers, and micronutrient fertilizers, combined with treating wounds with bactericides and protective agents, the re-germination of parasites can be prevented, and the tree's vigor can be restored.

Benefits of technology

It effectively controls the recurrence rate of parasitic infestation, enhances the resistance of fruit trees, promotes the recovery of tree vigor, ensures the normal growth and development of fruit, and achieves a fresh fruit weight of 18.3~24.6g, restoring normal growth levels.

Abstract

The present application relates to the technical field of macadamia planting, comprising the following steps: cutting diseased branches; chemical control: spraying 0.03-0.08% copper sulfate, 10-20 mg / L 2,4-dichlorophenoxyacetic acid, potassium fulvate 1800-2200 times liquid, 0.2-0.5% potassium dihydrogen phosphate, and tea bran water 150-300 times liquid on the macadamia nut trees from which the diseased branches are cut; tree vigor recovery: supplementing fertilizer at the roots of the macadamia nut trees from which the diseased branches are cut. The method of the present application can better prevent and inhibit the re-emergence of parasitic plants, and can also accelerate the renewal and rejuvenation of the macadamia nut trees, and ensure the normal growth and development of the fruits.
