Embodiment 1

[0031] Embodiment 1, a kind of fruit tree iron-rich special effect foliar fertilizer, its raw material is: ferrous sulfate 1.0Kg, histidine 0.25Kg, cysteine ​​0.25Kg, nicotinamide 0.25Kg, citric acid 0.25Kg, malic acid 0.25Kg, Tween 80 0.5Kg, EDTA 0.5Kg and water 100.0Kg.

[0032] The preparation steps are as follows:

[0033] 1. Put cysteine ​​into 50.0kg water, and then heat to 80°C to dissolve cysteine; obtain cysteine ​​aqueous solution;

[0034] 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;

[0035] 3. Add ferrous sulfate to the mixture, and adjust the pH to 4.5 with 1mol / L HCl solution to obtain iron-rich foliar fertilizer for fruit trees.

Embodiment 2

[0036] Embodiment 2, a kind of fruit tree iron-rich special effect foliar fertilizer, its raw material is: ferrous sulfate 2.0Kg, histidine 0.5Kg, cysteine ​​0.5Kg, nicotinamide 0.5Kg, citric acid 0.5Kg, malic acid 0.5Kg, Tween 80 1.0Kg, EDTA 1.0Kg and water 100.0Kg.

[0037] The preparation steps are as follows:

[0038] 1. Put cysteine ​​into 50.0kg water, and then heat to 80°C to dissolve cysteine; obtain cysteine ​​aqueous solution;

[0039] 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;

[0040] 3. Add ferrous sulfate to the mixture, and adjust the pH to 5 with 1mol / L HCl solution to obtain iron-rich foliar fertilizer for fruit trees.

Embodiment 3

[0041] Embodiment 3, a kind of fruit tree iron-rich special effect foliar fertilizer, its raw material is: ferrous sulfate 4.0Kg, histidine 1.0Kg, cysteine ​​1.0Kg, nicotinamide 1.0Kg, citric acid 1.0Kg, malic acid 1.0Kg, Tween 80 1.5Kg, EDTA 2.0Kg and water 100.0Kg.

[0042] The preparation steps are as follows:

[0043] 1. Put cysteine ​​into 50.0kg water, and then heat to 80°C to dissolve cysteine; obtain cysteine ​​aqueous solution;

[0044] 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;

[0045] 3. Add ferrous sulfate to the mixture, and adjust the pH to 5.5 with 1mol / L HCl solution to obtain iron-rich foliar fertilizer for fruit trees.

Abstract

The invention discloses an iron-rich foliar fertilizer for fruit trees. An base material aqueous solution of the iron-rich foliar fertilizer for fruit trees comprises: by weight, 2.0 to 4.0 parts of ferrous sulphate, 0.5 to 1.0 part of histidine, 0.5 to 1.0 part of cysteine, 0.5 to 1.0 part of nicotinamide, 0.5 to 1.0 part of citric acid, 0.5 to 1.0 part of malic acid, 1.0 to 1.5 parts of a surfactant, 1.0 to 2.0 parts of a chelating agent and 100 parts of water. Through pH adjustment, the base material aqueous solution has a pH value of 4.5 to 5.5 and forms the iron-rich foliar fertilizer for fruit trees. Through utilization of the iron-rich foliar fertilizer for fruit trees, the iron content and a nutrition value of a fruit are improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to an iron-rich special-effect foliar fertilizer for fruit trees. Background technique [0002] Iron is an essential trace element for the human body. It is widely distributed in the human body and is found in almost all tissues. It is also known as the "building material" for human development. However, the nutritional imbalance caused by iron deficiency is one of the main nutritional and health problems faced by human beings in the world. one. According to statistics, more than 3.5 billion people in the world are iron deficient, especially adolescents, pregnant women and the elderly, as many as 1.48 billion suffer from iron deficiency anemia, and the iron deficiency rate of children under 5 years old is as high as 35%; and 90% of iron deficient people live in developing countries. In China, about 70% of the people with micronutrient malnutrition are farmers, and 40% to 60% of c...
