Problems solved by technology

Carbonized rice husks are easy to break and have high carbonate content. When used in the production of substrates, it is difficult to maintain a good particle size structure and good permeability of the substrate, and it will increase the conductivity of the substrate, which is easy to cause yellowing. Seedling death phenomenon, underdeveloped root system, weak resistance, not conducive to strong seedlings
Therefore, the effect of using rice husk as a matrix material is not good and has not been paid attention to.

Embodiment 1

[0036] A method for deep fermentation of rice hulls of the present invention includes the following steps:

[0037] (1) Pretreatment: Dissolve urea in water and add it to rice husks, then add rapeseed cake and mix well, perform ammoniating treatment at room temperature (20℃~35℃), adjust the initial carbon to nitrogen ratio to 25, and then add water Mix well and adjust the initial moisture content to 60% to obtain the pretreated product; in this step, the normal temperature usually refers to 20°C to 35°C, the initial carbon to nitrogen ratio refers to the carbon to nitrogen ratio of the entire material to be fermented, and the initial moisture refers to the entire material to be fermented Of moisture.

[0038] (2) Add the fast-rot microbial agent to the pretreatment product, mix it and pile it into a stack of 2.2 meters wide, 1.2 meters high, and 3.5 meters long, and carry out stacking and fermentation treatment, turning the stack once every 3 days, one month The fermentation is co...

Abstract

The invention discloses a deep fermentation method of a rice hull and an application in producing a high-end substrate. The method comprises the following steps of: (1) adding urea and a rape seed cake into the rice hull for ammoniated treatment until the carbon nitrogen ratio is adjusted to 20-35 to obtain an ammoniated mixture, then adjusting the water content of the ammoniated mixture to 55-65percent to obtain a pretreatment product; (2) adding a fast decomposing microbial agent into the pretreatment product, carrying out the fermentation treatment of a pile-shaped pile, and realizing thedeep fermentation of the rice hull. The process is simple and convenient, the cost is low, the fermentation time is short, the fermentation effect is good, and the fermented product obtained by the method can be used for producing high-end substrates.

Description

Technical field [0001] The invention belongs to the technical field of organic fertilizer processing, and relates to a method and application of rice husk fermentation, in particular to a method of deep fermentation of rice husk and its application in the production of high-end substrates. Background technique [0002] As a kind of agricultural waste, rice husk has a carbon-to-nitrogen ratio of 75, which is one of the organic materials that are difficult to ferment. It is difficult to "subdued" it with general starters. The fermentation time is more than half a year by the way of ordinary pile fermentation, and the fermentation degree is not high, not soft enough, and the use ratio in the substrate is small. [0003] The application method of rice husk in substrate production is usually to burn it in isolation from air and then use it. Carbonized rice husks are easy to break and have a high carbonate content. When used in the production of substrates, it is difficult to maintain a...
