Embodiment 1

[0010] First use the meat grinder and pulverizer to grind the discarded aquatic products leftovers of aquatic products into meat sauce and powder, then put them into clean water and soak them overnight for 24 hours, then drain the water and add 1‰-1% volume weight For Bacillus subtilis inoculum, control the temperature at 28°C-37°C, stir evenly and carry out continuous composting fermentation, and the fermentation time is 3-7 days. After the fermentation is completed, it can be directly used for fertilizing fruit trees and crops. Filtration can be used to remove moisture.

Embodiment 2

[0012] Grind the scraps of aquatic products and put them into clean water to soak overnight for 24 hours, then filter to remove water, add Bacillus subtilis inoculum with a volume-to-weight ratio of 1‰, control the temperature at 28°C, stir evenly, and carry out continuous composting fermentation, fermentation time for 7 days.

[0013] The above-mentioned fertilizer is applied to the grape orchard, and the application rate is 700-1000 times of dilution and flushing.

[0014] After applying the fertilizer, the grape yield increased by 23% compared with that of the grape orchard without the fertilizer.

[0015]

Embodiment 3

[0017] Grind the scraps of aquatic products and put them in clean water to soak overnight for 24 hours, then filter to remove water, add 1% volume-to-weight ratio of Bacillus subtilis inoculum, control the temperature at 37°C, stir evenly, and carry out continuous composting fermentation, fermentation time for 3 days.

[0018] The above-mentioned fertilizer is applied to the grape orchard, and the application rate is 700-1000 times of dilution and flushing.

[0019] After applying the fertilizer, the grape yield increased by 25% compared with that of the grape orchard without the fertilizer.

Abstract

The invention provides a preparation method of a crop and fruit tree fertilizer. The preparation method comprises the steps of grinding raw materials into meat paste or powder by utilizing a meat grinder or a pulverizer, soaking in water, removing moisture, then adding a bacillus subtilis inoculant, controlling the temperature to be 28-37 DEG C, stirring and composting for continuous fermentation to obtain the crop and fruit tree fertilizer after the fermentation is completed. The fermented aquatic protein is conducive to the absorption of crops and grape fruit trees, and can quickly restore soil fertility and take an effect for a long time. The preparation method provided by the invention realizes the purpose of secondary comprehensive utilization of wastes, protects the living environment, improves the air permeability, water permeability and the like of soil, realizes the reuse of the soil, and also avoids the addition of a lot of chemical fertilizers. The crop and fruit tree fertilizer can be directly used for fertilization for fruit trees and crops.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizers, and relates to a method for preparing fertilizers for crops and fruit trees. It is a method for preparing fertilizers from biologically fermented aquatic leftovers, and is suitable for fertilizing crops or fruit trees. Background technique [0002] Wastewater from aquatic product processing contains about 0.5-2.0% soluble protein. Taking the surimi production industry as an example, the current annual output of surimi in my country is about 300,000 to 400,000 tons. According to the calculation of about 15 tons of wastewater per ton of surimi, 90,000 to 120,000 tons of water-soluble proteins are lost. The existing domestic technology cannot effectively recover and utilize protein, resulting in a large loss of high-quality protein resources and seriously polluting the environment. [0003] On the other hand, chemical fertilizers are commonly used in my country's agriculture. The ap...
