Embodiment 1

[0030] Embodiment 1, a kind of fruit tree zinc-rich foliage fertilizer, its raw material is: zinc sulfate heptahydrate 1.0Kg, histidine 0.25Kg, cysteine ​​0.25Kg, nicotinamide 0.25Kg, citric acid 0.25Kg, malic acid 0.25 Kg, Tween 800.5Kg, EDTA 0.5Kg and water 100.0Kg.

[0031] The preparation steps are as follows:

[0032] 1. Put cysteine ​​into 50.0kg of water, and then heat to 80°C to dissolve cysteine;

[0033]2. Dissolve histidine, nicotinamide, citric acid, malic acid, Tween 80 and EDTA in the remaining 50.0kg of water; then add cysteine ​​aqueous solution and shake well; obtain a mixed solution;

[0034] 3. Add zinc sulfate heptahydrate to the mixture, and adjust the pH to 5 with 1mol / L HCl solution to obtain zinc-rich special-effect foliar fertilizer for fruit trees.

Embodiment 2

[0035] Embodiment 2, a kind of fruit tree zinc-rich foliar fertilizer, its raw material is: zinc sulfate heptahydrate 2.0Kg, histidine 0.5Kg, cysteine ​​0.5Kg, nicotinamide 0.5Kg, citric acid 0.5Kg, malic acid 0.5 Kg, Tween 801.0Kg, EDTA 1.0Kg and water 100.0Kg.

[0036] The preparation steps are as follows:

[0037] 1. Put cysteine ​​into 50.0kg of water, and then heat to 80°C to dissolve cysteine;

[0038] 2. Dissolve histidine, nicotinamide, citric acid, malic acid, Tween 80 and EDTA in the remaining 50.0kg of water; then add cysteine ​​aqueous solution and shake well; obtain a mixed solution;

[0039] 3. Add zinc sulfate heptahydrate to the mixture, and adjust the pH to 4.5 with 1mol / L HCl solution to obtain a zinc-rich special-effect foliar fertilizer for fruit trees.

Embodiment 3

[0040] Embodiment 3, a kind of fruit tree zinc-rich foliage fertilizer, its raw material is: zinc sulfate heptahydrate 4.0Kg, histidine 1.0Kg, cysteine ​​1.0Kg, nicotinamide 1.0Kg, citric acid 1.0Kg, malic acid 1.0 Kg, Tween 80 1.5Kg, EDTA 2.0Kg and water 100.0Kg.

[0041] The preparation steps are as follows:

[0042] 1. Put cysteine ​​into 50.0kg of water, and then heat to 80°C to dissolve cysteine;

[0043] 2. Dissolve histidine, nicotinamide, citric acid, malic acid, Tween 80 and EDTA in the remaining 50.0kg of water; then add cysteine ​​aqueous solution and shake well; obtain a mixed solution;

[0044] 3. Add zinc sulfate heptahydrate to the mixture, and adjust the pH to 5.5 with 1mol / L HCl solution to obtain zinc-rich special-effect foliar fertilizer for fruit trees.

Abstract

The invention discloses a fruit tree zinc rich foliar fertilizer. Base material aqueous solution of the foliar fertilizer consists of the following components in parts by weight: 2.0-4.0 parts of heptahydrate zinc sulphate, 0.5-1.0 part of histidine, 0.5-1.0 part of cysteine, 0.5-1.0 part of niacinamide, 0.5-1.0 part of citric acid, 0.5-1.0 part of malic acid, 1.0-1.5 parts of surfactant, 1.0-2.0parts of chelating agent and 100 parts of water; and then the pH of the base material aqueous solution of the foliar fertilizer is adjusted to obtain the fruit tree zinc rich foliar fertilizer. By using the foliar fertilizer, the zinc content in plant fruits can be increased and the nutritive value of the plant fruits is increased.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a zinc-rich special-effect foliar fertilizer for fruit trees. Background technique [0002] Zinc is an essential micronutrient element for the human body. It directly or indirectly participates in the physiological and biochemical functions of the human body and plays an extremely important role in life activities. It is called "the flower of life" and "the element of wisdom" by the modern medical and nutritional circles . According to statistics, more than 3 billion people in the world are facing the problem of lack of micronutrient elements, among which iron and zinc deficiency in children aged 0-5 accounts for 35%. Adolescents and children in many areas of our country have varying degrees of zinc malnutrition. Zinc deficiency can lead to disorders of the human immune system, reduce work efficiency, cause female infertility or adverse pregnancy consequences, and affect childr...
