Embodiment Construction

[0021] In order to better understand the present invention, the embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0022] In order to convert the nutrient elements in freshwater fish into nutrients that are easily absorbed by plants, the invention provides a process for preparing bio-organic fertilizer from fish. The bio-organic fertilizer process of the present invention uses leftovers of fresh freshwater fish as raw materials, and utilizes biological fermentation technology to ferment and transform the raw materials.

[0023] see figure 1 , which is a schematic diagram of the first preferred embodiment of the process of fish biofertilizer of the present invention. The process specifically includes the following steps:

[0024] Step 101: Crushing freshwater fish leftovers into powder. Freshwater fish scraps include fish heads, fish tails, fish viscera, fish bones and other wastes left after processing freshwater ...

Abstract

The invention relates to a process for preparing biological organic fertilizer from fish. The process comprises the following steps of: crushing leftover materials of freshwater fish into powder; throwing the powder into a fermenting tank; throwing edible phosphoric acid into the fermenting tank; adding water into the fermenting tank; adding biological leaven into the fermenting tank; fermenting for 5 days by controlling the temperature of the fermenting tank to be between 16 and 35 DEG C; and filtering the liquid after fermentation. In the process, the powder of the leftover materials of the freshwater fish and the main ingredient leaven bacteria in the biological leaven are subjected to aerobic fermentation to decompose animal protein and animal fiber of the leftover materials of the freshwater fish; and nitrogen-fixing bacteria, phosphorus-dissolving bacteria, silicate bacteria, lactic acid bacteria and the like which are easily absorbed by plants are generated after decomposition, so the activity of soil nutrient, soil fertility and quality of agricultural products can be improved.

Description

【Technical field】 [0001] The invention relates to bio-organic fertilizers, in particular to a process for preparing bio-organic fertilizers from fish. 【Background technique】 [0002] Fertilizer is a necessity for the growth of crops and a necessary condition for agricultural production. Currently widely used fertilizers mainly include three types: organic fertilizers, inorganic fertilizers and bio-organic fertilizers. [0003] There are many kinds of organic fertilizers (such as human excrement, animal excrement and manure, green manure, compost and manure, etc.), and the source is wide and the quantity is large, which is convenient for local materials and local use, and the cost is relatively low. The characteristic of organic fertilizer is that it contains more comprehensive nutrients. It not only contains nitrogen, phosphorus, and potassium, but also contains calcium, magnesium, sulfur, iron, and some trace elements. However, most of these nutrients are in the state of ...
