Embodiment 1

[0045] A method for making water-soluble fertilizer by utilizing fish protein hydrolyzate, the method comprises the following steps: pretreatment, hydrolysis, concentration, neutralization and compounding.

[0046]The pretreatment includes washing, lyophilization, and grinding.

[0047] For the cleaning, put the fresh fish tissue into 3 times the volume of water, heat it up to 30°C, and ultrasonically clean it for 20min; filter out the fish tissue, put it into 3 times the volume of water again, heat it up to 40°C, and ultrasonically clean it for 30min ; filter out the fish tissue to complete the cleaning.

[0048] In the ultrasonic cleaning, the ultrasonic frequency is 30KHz.

[0049] The fish tissue is obtained from the waste materials of fish farms or fish product processing plants, including fish heads, fish scales, fish skins, fish steaks, fish bones, and fish internal organs.

[0050] In the cleaning, the fish tissue is thoroughly cleaned to remove the dirt and salt on ...

Abstract

The invention provides a method for preparing a water-soluble fertilizer from fish protein hydrolysate. The method comprises the following steps: pretreatment, hydrolysis, concentration, neutralization and compounding. According to the method for preparing the water-soluble fertilizer, hydrolysis is sufficient, nutrient substances in fish materials can be fully utilized, and meanwhile hydrolysis residues can be effectively prevented from being deposited in production equipment; the prepared water-soluble fertilizer is good in slow release effect, the loss of the water-soluble fertilizer in soil is effectively reduced, the utilization rate of the fertilizer is high, the fertilization operation frequency is effectively reduced, and the labor force and the planting cost of planters are effectively reduced; compared with an existing water-soluble fertilizer, the application amount is reduced by 10-13%, balanced nutrient elements can be provided for crops, and the water-soluble fertilizer is easily absorbed by the crops; after the fertilizer is applied for one year, the soil moisture content is increased by about 8-13%, and the soil porosity is increased by about 10-14%.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a method for making water-soluble fertilizers by utilizing fish protein hydrolyzate. Background technique [0002] my country is rich in aquatic resources. Since the 1990s, the annual total amount of aquatic products in my country has ranked first in the world, reaching 37.0 kilograms per capita. With the development of modern fishing technology and aquaculture technology, many small fish, shrimp and other low-value aquatic products can be quickly Reproduction has become the main source of aquatic economy, even far exceeding people's demand for fish protein. At the same time, although my country is rich in aquatic resources, the processing of aquatic products is seriously lagging behind. It is mainly based on rough processing, and there are very few finishing and deep processing products. Compared with developed countries, there is still a certain gap between its technology and product ...
