Efficient compound on-tree preservative agent for glorious oranges and preparation method thereof

Abstract

The invention discloses an efficient compound on-tree preservative agent for glorious oranges and a preparation method thereof, and the preservative agent comprises the following components in parts by weight: 0.7-2.0 parts of 2,4-sodium dichlorophenoxy acetate, 0.3-1.0 part of sodium bicarbonate, 28-40 parts of compound amino acid powder, 15-26 parts of boric acid, 4-12 parts of zinc sulfate, 7-18 parts of ammonium ferrous sulfate and 6-40 parts of potassium sulfate. The preparation method comprises the following steps: a) weighing the components; b) premixing the 2,4-sodium dichlorophenoxy acetate and the sodium bicarbonate in parts by weight; c) premixing the remaining components in parts by weight; d) mixing the mixtures obtained in the steps b and c again; and e) baking the mixture obtained in the step d in a baking oven at 50-60 DEG C, enabling the moisture content of the mixture to be less than or equal to 5 percent, crushing, sieving, inspecting, packaging, and obtaining the product. The on-tree preservative agent has good effect, convenient use, simple preparation method, low cost, no pollution to the environment and long shelf life.

Description

technical field [0001] The invention relates to a fruit fresh-keeping agent, in particular to a high-efficiency composite tree-retaining fresh-keeping agent for golden oranges and a preparation method thereof. Background technique [0002] Citrus is the largest fruit in the world, with a global planting area of ​​8.716 million hectares and an annual output of 122 million tons of fresh fruit. my country's citrus planting area is 1.967 million hectares, and the total annual fresh fruit output reaches 22.019 million tons, ranking first in the world. In countries with developed citrus industries, such as the United States and Brazil, a reasonable allocation of early, medium and late-maturing varieties is adopted to form a balanced supply of citrus fresh fruit and orange juice processing raw materials. my country's citrus is dominated by mid-ripening varieties, and the mid-ripening sweet oranges that mature from December to January of the next year account for more than 85% of t...

AI Technical Summary

Problems solved by technology

In recent years, sweet oranges commonly used to keep trees fresh are mostly achieved by spraying high-concentration 2,4-dichlorophenoxyacetic acid, combined with measures such as winter canopy mulching, but there are cumbersome operations, increased investment, overwintering fruit drop, and fruit loss. Issues such as aging and low yield in the following year
