Example Embodiment

Specific embodiment one

[0033] This embodiment provides a method for manufacturing a slow and controlled release fertilizer based on keel flower leaf, which includes the following steps:

[0034] Step a, warm up

[0035] Put 1000Kg of nitrogen, phosphorus and potassium compound granular fertilizer with a diameter of 2mm in the granulation equipment to preheat to 65℃;

[0036] Step b, coating

[0037] First, put 250 Kg of urea in a melting device controlled at 130℃ for melting. After the urea is completely melted, add 250 Kg of sulfur powder, 8 Kg of polyvinyl alcohol and 10 Kg of phenyl acrylate, and then filter after stirring. A uniform texture of molten urea resin sulfur liquid; then the preheated fertilizer particles are formed into a material curtain in the granulation equipment, and the molten urea resin sulfur liquid is sprayed uniformly on the surface of the fertilizer particles by air pressure spraying at a spray pressure of 0.35 MPa-0.45MPa, the coating amount is the mass r...

Example Embodiment

Specific embodiment two

[0044] This embodiment is also an embodiment of a method for manufacturing a slow and controlled release fertilizer based on keel flower leaf. The difference from the first embodiment is that the quality of the keel flower leaf extract added in step b of this embodiment is 0, 5, 10, 15, 20, 25, 30 and 35 Kg, and according to the specific embodiment 1. Methods Seven groups of slow and controlled release fertilizers were obtained.

[0045] The slow and controlled release of these seven groups of slow and controlled release fertilizers were compared. The comparison method used to monitor the time taken when the urea content in the fertilizer was degraded to 10%. The results of the comparison were: 0, 5, 10, 15 for the keel flower leaf extract. In the case of, 20 and 25 Kg, the time used increases sequentially, indicating that within these data ranges, the slow and controlled release effect increases with the increase of keel flower leaf extract, while for ke...

Example Embodiment

Specific embodiment three

[0046] This embodiment provides a method for extracting the keel flower leaf extract described in specific embodiment 1, and the method includes:

[0047] Pre-treatment: In a vacuum environment, place the yellow keel flowers and leaves that fall off automatically under a purple light for 60 days;

[0048] Mid-term treatment: place the keel flower leaf at 200℃ for 1 minute, then quickly place it in the ice water mixture at 0℃;

[0049] Post-processing: boil the ice-water mixture with keel flower leaves, evaporate part of the water, and make the ratio of aqueous solution and keel flower solute to 10:1.

Abstract

The invention provides a production method of a controlled release chemical fertilizer based on hylocereus undulatus leaves, belongs to a production process of a controlled release chemical fertilizer, and particularly relates to a production method of a controlled release adjustable chemical fertilizer. The production method comprises the step of adding hylocereus undulatus leaf extract on the basis of a traditional process after urea is completely melted. By virtue of the technological means, only the hylocereus undulatus leaf extract needs to be added on the basis of a traditional controlled release chemical fertilizer, so that the controlled release effect of the traditional controlled release chemical fertilizer can be adjusted; the chemical fertilizer prepared by the method not only has an ideal controlled release effect but also has a simple process and is low in production cost; meanwhile, secondary pollution to soil is not caused; and more importantly, the controlled release effect can be adjusted so that the chemical fertilizer can meet wide market requirements.

Description

technical field [0001] The invention discloses a method for manufacturing slow-controlled release chemical fertilizers based on keel flowers and leaves, which belongs to the manufacturing process of slow-controlled release chemical fertilizers, and in particular relates to a manufacturing process of slow-controlled release adjustable fertilizers. Background technique [0002] At present, there are mainly four types of slow-release fertilizers in the international fertilizer market: stable nitrogen fertilizers containing transformation inhibitors, organically synthesized slow-release nitrogen fertilizers, polymer-coated slow-release fertilizers and coated slow-control fertilizers. Release fertilizer. [0003] First, stable nitrogen fertilizer containing transformation inhibitors [0004] Hydrogen and ammonium dihydrogen are usually used to inhibit urease and nitrification agents. Its main function is to inhibit nitrogen loss during urea conversion and nitrification, reduce g...
