Example Embodiment

[0025] Example 1

[0026] A preparation method of a special compound fertilizer for ginkgo trees based on cyanobacteria, comprising the following steps:

[0027] Step 1. Take cyanobacteria, squeeze to remove excess water to obtain wet cyanobacteria, add 10Kg of water to 1Kg of wet cyanobacteria, then add 0.05Kg of cellulase and 0.05 Kg of protease, mix well, heat to 40 ° C, and the enzyme After dissolving for 2 hours, and then inactivating the enzyme, the enzymatic hydrolysis solution was obtained;

[0028] In the second step, add 0.05Kg of potassium sulfate to the enzymatic hydrolysis solution, heat to 80°C, keep it for 3 hours, and after cooling, vacuum-concentrate the feed solution until the volume is reduced to 1 / 3 to obtain a concentrated solution;

[0029] Step 3: Add 0.03Kg sodium humate, 0.03Kg potassium humate, 0.1Kg urea, 0.1Kg ammonium bicarbonate, 0.05Kg phosphogypsum, 0.05Kg potassium citrate, 0.02Kg zinc sulfate, 0.02Kg amino acid to the concentrated solution ,...

Abstract

The invention relates to a preparation method of a compound fertilizer dedicated to ginkgo trees, in particular to a preparation method of the compound fertilizer dedicated to ginkgo trees by using blue-green algae as a base material, belonging to the technical field of fertilizers. The preparation method comprises the steps of squeezing blue-green algae to remove excessive moisture to obtain wet blue-green algae, sequentially adding water, cellulase and protease in parts by weight, mixing uniformly, heating, carrying out enzymolysis, and performing enzyme deactivation to obtain enzymatic hydrolysate; adding potassium sulphate in the enzymatic hydrolysate, heating, keeping the temperature for 3-5h, cooling, and carrying out vacuum concentration to obtain concentrated solution; adding sodium humate, potassium humate, ammonium bicarbonate, phosphogypsum, potassium citrate, zinc sulfate, amino acid, polyvinyl alcohol, cellulose and calcium carbide in the concentrated solution, stirring uniformly, spray-drying, and then granulating to obtain a product. The compound fertilizer dedicated to the ginkgo trees can enable the ginkgo trees to have higher stems and more leaves and have high content of active substances.

Description

[0001] technical field [0002] The invention relates to a preparation method of a special compound fertilizer for ginkgo trees, in particular to a preparation method of a special compound fertilizer for ginkgo trees with blue-green algae as a base material, and belongs to the field of fertilizer technology. [0003] Background technique [0004] Ginkgo biloba is an excellent tree species with both fruit and wood. It is tall and beautiful, and it is also a beautiful ornamental tree species. Ginkgo biloba has strong adaptability to soil, is resistant to acid, alkali, and drought, and has a lifespan of hundreds or even thousands of years. It is called "Gongsun tree" by the masses. The fruit is rich in ginkolic acid and ginkgool, rich in nutrition, edible, and can also be used as medicine. The leaves can make medicines such as "coronary ketone", and can be used as paddy field fertilizers and insecticides. Its wood is light, flexible, tough, fine-grained, and not easy to warp...
