Embodiment 1

[0030] A Jincheng high-efficiency composite tree-retaining preservative is characterized in that it is made of the following components by weight: 2,4-dichlorophenoxy sodium acetate: 1.2kg; sodium bicarbonate: 0.60kg; compound amino acid powder: 33.75 kg; boric acid: 20.61kg; zinc sulfate: 7.91kg; ferrous ammonium sulfate: 12.65kg; potassium sulfate: 23.28kg.

[0031] see figure 1 , the preparation method of the above-mentioned Jincheng high-efficiency composite tree-retaining preservative, specifically comprising the following steps:

[0032] a), take each component by weight part;

[0033] b), 2,4-dichlorophenoxy sodium acetate and sodium bicarbonate are premixed in parts by weight;

[0034] c), premixing compound amino acid powder, boric acid, zinc sulfate, ferrous ammonium sulfate, and potassium sulfate by weight;

[0035] d), the mixture obtained in steps b and c is carried out secondary mixing;

[0036] e), the mixture obtained in step d is dried in an oven at 50-60°...

Embodiment 2

[0038] A Jincheng high-efficiency composite tree-retaining agent is characterized in that it is made of the following components by weight: 2,4-dichlorophenoxy sodium acetate: 1.50kg; sodium bicarbonate: 0.72kg; compound amino acid powder: 35.63 kg; boric acid: 22.33kg; zinc sulfate: 9.23kg; ferrous ammonium sulfate: 14.76kg; potassium sulfate: 15.84kg.

[0039] The preparation method is the same as in Example 1.

[0040] The method of using Jincheng high-efficiency compound tree-retaining preservative: Dilute the Jincheng high-efficiency compound tree-retaining preservative 600 times, during the color change period (early November) of Jincheng fruit, the ripening period (early December) and before the low temperature comes ( In the first ten days of January) Spray once on each sunny day, focusing on the fruit and spraying the whole plant.

Embodiment 3

[0042] A Jincheng high-efficiency composite tree-retaining preservative is characterized in that it is made of the following components by weight: 2,4-dichlorophenoxyacetic acid sodium: 0.7kg; sodium bicarbonate: 0.3kg; compound amino acid powder: 28kg ; Boric acid: 15kg; Zinc sulfate: 4kg; Ferrous ammonium sulfate: 7kg; Potassium sulfate: 6kg.

[0043] The preparation method is the same as in Example 1, and the use method is the same as in Example 2.

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...
