Embodiment 1

[0018] In parts by weight, the following components are used:

[0019] 15 parts of straw, 8 parts of shell powder, 20 parts of kaolin, 7 parts of woody plant powder, 5 parts of water retaining agent, 1 part of potassium salt and 4 parts of urea, the particle size of straw is 30 mesh; Prepared by mixing, the mass ratio of oyster shells and mussel shells is 3:1.

[0020] In this embodiment, the woody plant is paulownia, of course, it can also be other woody plants, such as pine and cypress.

[0021] Water retaining agent is a functional polymer material with particularly strong water absorption capacity. Non-toxic and harmless, it releases and absorbs water repeatedly. It is a kind of "miniature reservoir". At the same time, it can also absorb fertilizers and pesticides and release them slowly to increase fertilizer and drug effects. In this embodiment, the water-retaining agent is ammonium polyacrylate, of course, it can also be other water-retaining agents, such as starch gr...

Embodiment 2

[0025] In parts by weight, the following components are used:

[0026] 25 parts of straw, 20 parts of shell powder, 30 parts of kaolin, 15 parts of woody plant powder, 10 parts of water retaining agent, 5 parts of potassium salt and 9 parts of urea, the particle size of straw is 60 mesh; Prepared by mixing, the mass ratio of oyster shells and mussel shells is 4: 1.5.

[0027] In this embodiment, the woody plant is camellia, and the water-retaining agent is polystyrene amide.

Embodiment 3

[0029] In parts by weight, the following components are used:

[0030] 19 parts of straw, 12 parts of shell powder, 25 parts of kaolin, 10 parts of woody plant powder, 7.5 parts of water retaining agent, 3 parts of potassium salt and 6 parts of urea; shell powder is made by mixing oyster shells and mussel shells, oyster shells and mussel shells The mass ratio of shells is 3.2:1.2.

[0031] In this embodiment, the particle size of the straw is 40 mesh. The selection of straw particle size can provide convenience for the mixing of various raw material components. The woody plants are pine trees, and the water-retaining agent is polystyrene amide.

[0032] In this embodiment, the particle size of shell powder is 55 mesh, and the particle size of kaolin is 50 mesh. Of course, the above selection is not a limitation, and shell powder and kaolin of other meshes can also be used, for example, 40 mesh of shell powder and 30 mesh of kaolin are selected.

Abstract

The invention provides fertilizer and relates to the technical field of chemical products. The fertilizer comprises the following ingredients in parts by weight: 15-25 parts of straw, 8-20 parts of shell powder, 20-30 parts of kaoline, 7-15 parts of woody plant powder, 5-10 parts of water retention agent, 1-5 parts of sylvine and 4-9 parts of urea, wherein the straw is 30-60 meshes in particle size; the shell powder is prepared by mixing oyster shells and mussel shells at a mass ratio of (3-4):(1-1.5). The fertilizer can utilize the straw wasted originally, and saves resources, and the prepared fertilizer can effectively improve soil and has a water retention effect.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a fertilizer. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after the seeds are harvested. After harvesting the seeds, people often discard the straw, or even burn the straw, which not only wastes resources, but also damages the ecological environment. Contents of the invention [0003] In view of this, the invention provides a fertilizer to improve the problem of straw waste. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A fertilizer, the composition of which is as follows in parts by weight: 15-25 parts of straw, 8-20 parts of shell powder, 20-30 parts of kaolin, 7-15 parts of woody plant powder, 5-10 part...
