Efficient picking method for macadamia nuts

Abstract

The invention belongs to picking technology of agricultural and forestry crops, in particular relates to an efficient picking method for macadamia nuts. The efficient picking method includes steps of rooting out weeds under trees and flattening the earth from the late August to the middle of September every year; preparing ethephon solution in concentration 1.4-1.8g / l, adding washing powder in same mass with ethephone into the ethephon solution, regulating pH (power of hydrogen) to 6.7-7.2 by sodium bicarbonate; uniformly spraying the surface of macadamia trees uniformly in sunny day with wind power at 0-1 level and humidity smaller than 85% until all leaves are wet, re-spraying if rain falls within four hours after spraying; picking nuts once every two weeks, picking three or four times to complete the entire picking process, pealing the picked-up nuts, drying and storing in an indoor air mesh bed. Compared with the conventional manual tree-climbing beating and picking process, the efficient picking method can greatly reduce labor cost for picking the macadamia nuts and reducing nut loss, and nut quality and tree growth can be unaffected.

Description

technical field [0001] The invention belongs to the harvesting technology of agricultural and forestry economic crops, and in particular relates to a high-efficiency harvesting method of macadamia nuts. technical background: [0002] Macadamia( Macadamia integrifolia spp.) is the genus Macadamia (Proteaceae) Macadamia ) Evergreen tree, native to Australia, its nuts have a fat content of 65%~83%, rich in a variety of unsaturated fatty acids and essential amino acids, trace elements and vitamins, long-term consumption can help reduce blood total cholesterol, Prevent arteriosclerosis, reduce the viscosity of platelets, reduce the incidence of heart disease, myocardial infarction and other cardiovascular diseases. The large-scale commercial planting of macadamia nuts began in Hawaii in 1948, so it is also called macadamia nuts. At present, its planting scope has expanded to the Americas, Australia, Kenya, South Africa, Southeast Asia and other countries and regions. [00...
