Embodiment Construction

[0018] The invention provides a method for preparing fermented sawdust / sawdust organic fertilizer, comprising the steps of:

[0019] (1) Raw material selection: select sawdust and shaving powder left over from woodworking processing;

[0020] (2) Moisture control: Pour the above-mentioned wood chips on the fermentation tank, and use a water gun to spray evenly from the top to the surrounding area. After the wood chips are wet, add plant fermentation bacteria and mix them. The required moisture ratio is 60%-65%. Add 1 kg of plant fermentation bacteria;

[0021] (3) Initial pile fermentation: In the above-mentioned mixture of wood chips and plant fermentation bacteria, multiple wood chip fermentation piles are built by spreading bacteria while piling up, and a thermometer is inserted into each wood chip fermentation pile to observe the temperature change. Less than 80 cm, width not less than 2 meters and total volume of a single fermentation pile not less than 3 cubic meters; ...

Abstract

The invention relates to a method for preparing organic fertilizer by fermenting wood chips / sawdust. The method can effectively ferment wood chips / sawdust into organic fertilizer, effectively reuses plant wastes, and broadens the preparation scheme in the field of preparation of organic fertilizer; according to the scheme, fermentation and turnover are adopted for a plurality of times, so that plant fermentation bacteria and the wood chips are enabled to be evenly mixed so as to be fully fermented; furthermore, the relevant environmental parameters are reasonably set, so that the nutrition, color, appearance and odor of the organic fertilizer obtained by fermentation are greatly improved.

Description

technical field [0001] The invention relates to the field of plant organic fertilizers, in particular to a method for preparing fermented sawdust / sawdust organic fertilizers. Background technique [0002] The preparation methods of plant organic fertilizers that are common in the market at present, such as: corn or wheat straw, hay, etc., can effectively convert plant waste into organic fertilizers, and then use them to exert secondary value; [0003] For the sawdust, shavings and other powdered wood chips left during wood processing, they are usually not used for the preparation of organic fertilizers, but are only used for filling or hygroscopic properties of powdered wood chips, and there is no breakthrough in the preparation of organic fertilizers. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing fermented sawdust / sawdust organic fertilizer. [0005] The invention provides a method for preparing fermented saw...
