Embodiment Construction

[0042] figure 1 It is a schematic flow chart of a method for preparing fertilizer provided by the embodiment of the present invention. see figure 1 , the method includes:

[0043] S101. Obtain waste liquid after anaerobic fermentation of the hemicellulose aqueous solution, where the hemicellulose in the hemicellulose aqueous solution comes from straw.

[0044] S102. Obtain the fertilizer by mixing the waste liquid with chemical fertilizer.

[0045] For example, the pH value of the hemicellulose aqueous solution is equal to 7 or approximately equal to 7.

[0046] For example, the straw includes: cereal straw, reed, wood, flax, corn straw, miscanthus, giant fungus grass, sunflower straw, walnut shells, weeds, edible fungus waste, cotton straw and potato seedlings at least one of .

[0047] For example, the corn stover includes grain husks and bran, and the corn stover includes corn cobs.

[0048] The hemicellulose aqueous solution contains organic matter. Through anaerobi...

Abstract

The invention provides a fertilizer. The fertilizer comprises a waste liquid obtained from anaerobic fermentation treatment of a hemicellulose aqueous solution and a chemical fertilizer, wherein hemicellulose in the hemicellulose aqueous solution comes from straw. The fertilizer is helpful to reduce the dosage of the chemical fertilizer, and reduces the negative effect of the chemical fertilizer on soil.

Description

technical field [0001] The present invention relates to the field of chemistry, in particular to fertilizers. Background technique [0002] Fertilizer is a widely used fertilizer for crops. When the nitrogen, phosphorus or potassium in the soil cannot meet the needs of crop growth, fertilizers containing nitrogen, phosphorus or potassium can be applied. [0003] However, while chemical fertilizers increase crop yields, they also have a negative effect on the soil. [0004] On the one hand, the application of chemical fertilizers has increased heavy metals and other toxic substances in the soil. Raw materials for making fertilizers may contain heavy metals. In addition, the process of making fertilizers may also introduce heavy metals. This makes fertilizers also contain heavy metals. For example, the raw material for preparing phosphate fertilizer can be phosphate rock. Phosphate rock contains fluorine (F) and arsenic (As). [0005] On the other hand, chemical fertili...
