Problems solved by technology

In the prior art, the method for changing the color of apples is usually realized by laying reflective film during the apple coloring period. This method is time-consuming and laborious, and cannot improve the flavor of apples, but reduces the flavor of apples to some extent.
[0003] The use of water-soluble fertilizers to improve the color of apples or to improve the flavor of apples has become a hot spot in scientific research, but the water-soluble fertilizers used to improve the color or flavor of apples in the prior art exist in liquid form, and this form of water-soluble fertilizers is not stable; and the existing The technical water-soluble fertilizer has a single fertilizer effect, and cannot satisfy both the effect of improving the color and flavor of apples at the same time

preparation example Construction

[0045] The present invention also provides the preparation method of the water solubility fertilization, including the steps of:

[0046] (1) The components in the water solubility fertilizing fertilization are mixed with water, dissolved to obtain intermediate liquid 1;

[0047] (2) The intermediate liquid is 1 homogenesis to obtain intermediate liquid 2;

[0048] (3) The intermediate liquid 2 was dried to give water-soluble fat.

[0049] In the present invention, the mass ratio of the water-soluble fat and water is 1: 1 to 2, preferably 1: 1.5;

[0050] Step (1) The dissolution is stirred and dissolved;

[0051] The stirring speed is 120 to 150 rpm, preferably 135 rpm;

[0052] The dissolved time is 30 to 40 min, preferably 35min;

[0053] The dissolved temperature is 50 to 60 ° C, preferably 55 ° C.

[0054] In the present invention, the homogeneous pressure of step (2) is 160 to 180 MPa, preferably 170 MPa;

[0055] The homogeny time is 10 to 15 min, preferably 12.5 min.

Abstract

The invention provides a water-soluble fertilizer for improving apple quality and a preparation method and application thereof, and relates to the technical field of fertilizers. The water-soluble fertilizer comprises the following components in parts by mass: 40-50 parts of potassium pyrophosphate, 10-20 parts of urea, 1-3 parts of ammonium nitrate, 7-9 parts of cane sugar, 1-3 parts of ethephon, 0.5-1.5 parts of abscisic acid, 2-4 parts of chelated iron, 1-3 parts of chelated zinc, 2-4 parts of chelated copper, 2-4 parts of chelated manganese, 1-3 parts of chelated magnesium, 3-5 parts of boric acid, 3-5 parts of potassium molybdate and 7-9 parts of sodium hyaluronate. The water-soluble fertilizer prepared according to the preparation method can improve the coloring degree of apples, increase the yield of the apples and improve the flavor of the apples.

Description

Technical field [0001] The present invention relates to the field of fertilizers, and more particularly to a water solubility fertilizer and preparation method thereof in improving apple quality. Background technique [0002] As the public's consumption levels are gradually improved, people's quality requirements for Apple are getting higher and higher, not only requires beautiful colors, but also requires delicious. The prior art method for changing the color of Apple is usually achieved in the production of reflective films in apple, this method is expensive, and the apple's flavor is not improved, but the apple flavor has decreased. [0003] Use water-soluble fat to improve the color of Apple or improve Apple's flavor to become hot spots in scientific research, but prior art is used to improve apple color or flavor water-soluble fat in liquid form, this form of water solubility is unstable; and existing Technical water-soluble fertilizer is single, and it is not possible to me...
