Macadamia-nut cold-proof method

Abstract

The invention relates to the field of agriculture, in particular to a macadamia-nut cold-proof method. According to the macadamia-nut cold-proof method, macadamia nut trees are subjected to cold-prooftreatment with a combined method of advance topdressing and protection agent applying, so that all reasonable elements are supplemented in advance to the macadamia nut trees, stagnation of growing development of the macadamia nut trees when the low-temperature period comes is reduced, and the problems that as the cold weather influences on the macadamia nut trees, the flower period is postponed,and the fruit setting rate is reduced are solved; applying is carried out with cold-proof protection agent, characteristics of raw materials such as kieselguhr, lime sulphur, Chinese-prickly-ash cakemeals, rosin, peach gum, magnesium aluminum silicate or magnesium lithium silicate and seaweed extract are fully developed, and finally, the macadamia-nut cold-proof method capable of effectively preventing macadamia-nut young trees from being cold injured and died from cold and solving the problems that as the cold weather influences on macadamia nut mature trees, the flower period is postponed,and the fruit setting rate is reduced is obtained.

Description

technical field [0001] The invention belongs to the field of agriculture, in particular to a cold-proof method for macadamia nuts. Background technique [0002] Macadamia nut (Latin scientific name: Macadamia ternifolia F.Muell.) Alias: Queensland chestnut, macadamia walnut, macadamia nut, Queensland fruit, is a tree nut native to Australia. Macadamia nuts are evergreen trees and dicotyledonous plants. The crown is tall, with 3-4 whorls of leaves, lanceolate, leathery, smooth, with spiny serrations on the edges. Racemes axillary, beige flowers, spherical fruit, leathery, hard endocarp, beige to light brown kernels. 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 , the rough shell species is 4.8; the protein is 9%, and it is also rich in calcium, phosphorus, iron...

AI Technical Summary

Problems solved by technology

[0004] Macadamia trees have strong stress resistance and can tolerate short-term low temperatures of about -5°C, but frostbite will still occur under longer low temperatures, and the cold weather in early spring has an impact on macadamia flower spikes and flowering Larger ones will delay the flowering period of macadamia nuts and reduce the fruit setting rate. Young trees under 3 years old have poor cold resistance and are prone to frost damage, resulting in frostbite or freezing to death
