Embodiment 1

[0043] The raw materials were weighed according to the following parts by weight: 10 parts of fish manure, 10 parts of residual bait, 4 parts of sugarcane filter mud, and a compound fermentation bacterial agent equivalent to 0.25% of the weight of sugarcane filter mud was added.

[0044] The compound bacterial agent is domesticated bacteria freeze-dried powder, yeast freeze-dried powder, Pseudomonas aeruginosa freeze-dried powder and Bacillus freeze-dried powder, and the weight ratio is 3:2:2:1.

[0045] The preparation method of the composite solid compost is:

[0046] (1) Use microfilters with different small apertures to filter the tail water of culture, obtain organic matter such as fish manure and residual bait in turn, dry them, and save them for future use.

[0047] (2) Mix the sugarcane filter mud, fish manure, residual bait and compound fermentation inoculum in a ratio of 10:10:4:0.01 (the ratio of compound inoculum is 3:2:2:1), stir evenly, and pile them into a certa...

Abstract

The invention discloses a method for preparing a sugarcane fertilizer from culture tail water filtration residues, which comprises the following steps: filtering culture tail water through microstrainers with different small apertures to obtain fish manure and residual bait, adding sugarcane filter mud and a compound fermentation inoculant, and carrying out aerobic composting to obtain a solid fertilizer. The solid fertilizer disclosed by the invention is synthesized according to the growth characteristics of the sugarcane and scientific treatment and scientific proportioning of culture tail water residues, and meets the nutritional requirements in the growth process of the sugarcane. The culture tail water is filtered, the culture tail water can be scientifically treated, the purification level and quality of the culture tail water are improved, and the yield and quality of sugarcanes can be improved. In addition, by-product filter mud of a cane sugar factory is also added into the fertilizer, so that high-value utilization of by-products is realized.

Description

technical field [0001] The invention relates to the technical field of solid fertilizers, in particular to a method for preparing a sugarcane solid fertilizer by filtering residues of aquaculture tail water. Background technique [0002] The aquaculture tail water refers to the aquaculture water that is no longer used and discharged from the entire aquaculture system during the aquaculture process or after the aquaculture work is completed. It contains a large amount of pollutants, including ammonia nitrogen, organic matter, etc. deterioration, further reducing the growth rate and quality of fish and shrimp. Scientific and rational treatment of tail water is of great significance for protecting aquaculture waters, creating a suitable growth environment for fish, effectively reducing the probability of disease occurrence, and improving aquaculture benefits. [0003] Filter mud is a by-product of sugar cane processing. It contains a lot of organic substances, mainly cellulose...
