Method for protecting flowers and fruits of macadamia nuts

Abstract

The invention provides a method for protecting flowers and fruits of macadamia nuts. Basic fertilizer is applied after the fruits of the macadamia nuts are harvested; the basic fertilizer is prepared from the following raw materials in parts by weight: 8 to 10 parts of urea, 3 to 5 parts of potassium phosphate, 40 to 60 parts of composted fowl manure, 8 to 10 parts of a water retention agent and 3 to 5 parts of vermiculite powder. At a flowering period of the macadamia nuts, artificial supplementary pollination or insect supplementary pollination is carried out, and flower-protecting water-soluble fertilizer is sprayed at the flowering period; the flower-protecting water-soluble fertilizer is prepared from the following raw materials in parts by weight: 3 to 5 parts of borax, 10 to 15 parts of sodium alginate, 1 to 3 parts of sodium nitrophenolate, 1 to 2 parts of zinc fertilizer and the balance of water which is supplemented until the total content is 100 parts. Fruit-protecting water-soluble fertilizer is sprayed at a fruit setting period of the macadamia nuts; the fruit-protecting water-soluble fertilizer is prepared from the following raw materials in parts by weight: 2 to 4 parts of potassium dihydrogen phosphate, 10 to 15 parts of sodium alginate, 2 to 3 parts of sodium nitrophenolate and the balance of water which is supplemented until the total content is 100 parts. By adopting the method provided by the invention, flower falling and fruit falling of the macadamia nuts can be effectively controlled, the yield of the fruits is improved and the benefits are increased; tree bodies are kept healthy and strong.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for preserving flowers and fruits of macadamia nuts. Background technique [0002] Macadamia ternifolia F., also known as macadamia nut, belongs to the family Longanaceae. The flowering period is March-April and the fruiting period is August-September. The kernel of macadamia nuts is rich in nutrition (milky white), the outer skin is green, the inner skin is hard and brown, the weight of a single fruit is 15-16 grams, the oil content is about 70%, the protein is 9%, and it contains 8 kinds of amino acids necessary for human body Including 17 kinds of amino acids, also rich in minerals and vitamins. Macadamia nuts are crispy, tender and delicious, with a unique buttery aroma. They are the highest quality edible fruit in the world. They are known as the "Queen of Dried Fruits" and "King of Nuts in the World". The flavor and taste are far better than cashews...

AI Technical Summary

Problems solved by technology

[0003] Most macadamia nuts bloom in large quantities every year, but only 0-2% of the flowers finally grow into fruits, and more than 98% of the flowers fall off after flowering (early stage) or young fruit development stage (late stage), and excessive flower and fruit drop , not only affect the yield and benefit, but also weaken the tree vigor of the fruit tree itself
