Production process for manufacturing liquid fertilizer by using fish waste

Abstract

The invention discloses a production process for manufacturing a liquid fertilizer by using fish waste, which comprises the following steps: firstly, mixing fish waste and water in a certain ratio for boiling, and cooling the mixture to obtain a colloidal semi-finished product; secondly, mixing the colloidal semi-finished product with water, edible brown sugar, enzyme bacteria and humic acid in a ratio; thirdly, placing the mixture in a barrel head for fermentation, wherein during fermentation, the mixture fermenting in a barrel is stirred for 10 minutes each 24 hours; and finally, obtaining a finished product after complete fermentation. By the process, organic substances in the fish waste are fermented and decomposed, so that organic substances that are difficult to be absorbed by plants are converted into N, P, K and other inorganic nutritive elements and trace elements that are easy to absorb for plants to meet the need for absorbing nutritive elements of plants for growth. The method has the advantages of smart conception, simple manufacturing process, low cost and great benefits. The liquid fertilizer manufactured by the process can effectively improve soil, protect flowers and fruits, increase yield of crop and improve the quality of agricultural products.

Description

technical field [0001] The invention relates to the technical field of fertilizer production technology, in particular to a production technology for making liquid fertilizer from fish waste. Background technique [0002] At present, there are a lot of other fish wastes such as fish heads, fish tails and viscera left after the production of fish products processing plants. Fish wastes are rich in organic nutrients such as protein and fat. Generally, fish wastes are processed into powder, When added to fertilizers or other products, it is difficult for the nutrients in fish waste to be fully absorbed and utilized by plants. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcoming of the prior art, provide a kind of ingenious design, utilize the production technology of the liquid fertilizer of the nutrient element that the plant absorbs easily after utilizing fish waste to ferment. [0004] The present invention...
