Embodiment 1
[0032] A special fertilizer for longan trees, made from the following raw materials in parts by weight:
[0033] 35 parts of livestock and poultry manure; 25 parts of starch residue; 20 parts of moldy feed; 10 parts of cottonseed meal; 10 parts of edible fungus residue; 5 parts of humic acid; 155 parts of urea; 160 parts of potassium chloride; 90 parts of superphosphate; 10 parts of lignin; 7 parts of amino acid chelated copper and boron; 7 parts of sucrose complexed manganese and calcium; 3 parts of ferric diamine fulvic acid;
[0034] The preparation method of the amino acid chelated copper and boron is as follows: fully dissolve the compound amino acid powder in water to obtain a solution, heat to maintain the temperature between 75-80°C, adjust the pH value to 6.0-7.0, and then follow the compound amino acid : The molar ratio of copper sulfate: boric acid is 4:1:1. Add copper sulfate to the solution first, react for 1 hour, and then add boric acid to react for 1.5 hours. T...
