Rapid fermentation method of bagasse and preparation of floating seedling substrate with fermented bagasse

Abstract

The invention provides a quick bagasse fermentation process and a method for preparing float breeding matrixes through bagasse. The method includes the implementing steps that sugar mud and brown coal are added into the smashed bagasse and are mixed evenly, then the carbon-nitrogen ratio is adjusted through nitrogenous fertilizers, the microorganism probiotic bacteria are added into the bagasse mixtures in proportion after being subjected to activating and propagating expanding and are mixed evenly to serve as fermentation materials, the fermentation materials are put into a fermentation tank, static fermentation is conducted for 50-60 days, decayed fermentation bagasse is obtained, the decayed fermentation bagasse is mixed with extrusion perlite and vermiculite are mixed in proportion, the float breeding matrixes are obtained after the mixtures are stirred evenly, and the moisture content of the adjustment matrixes ranges from 30% to 40%. By means of the method, the bagasse fermentation time is shortened by 44% to 67%, the fermentation time is short, the use cycle of the fermentation tank is short, the occupied field is small, the investment cost is low, the preparing yield is large, the benefits are high, the bagasse type float breeding matrixes can replace the method of grass carbon type float breeding matrixes, the exploit and utilization of non-renewable resources are reduced, and ecological benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a rapid fermentation method of bagasse and preparation of a floating seedling-raising substrate by fermenting bagasse. Background technique [0002] Floating seedling cultivation technology combines the advantages of matrix cultivation, hydroponics, container cultivation and pollution-free cultivation, and has been widely used in the production of tobacco, vegetables, flowers, seedlings and other seedlings. [0003] The substrate is the foundation of floating seedlings and an important factor determining the growth environment of seedling roots. In the process of floating seedlings, the substrate not only supports and fixes the plants, but also plays an important role as a nutrient transfer station. The nutrients in the nutrient solution and The water is transferred through the seedling substrate and then absorbed by the roots of the plants. [0004]...

Problems solved by technology

But because the crude fiber contained in the bagasse is very high, as high as 44% to 46%, and the carbon-to-nitrogen ratio is as high as 170 to 190, the fermentation method of the prior art ferments the decomposed bagasse for more than 3 months, and the application number is 200710052296.1 patent publication The technical scheme of the bagasse fermenting and decomposing process requires retting for 3-8 months, and the technical solution disclosed in the patent application number 200710101516.5 requires 8-12 months for the bagasse fermenting and decomposing process, and the fermentation and decomposing speed is slow, and the required time is longer. The efficiency is low, the production process needs to occupy a large number of fermentation sites, the investment cost is high, the processing output is small, and the benefit is low, which is not conducive to the implementation and application of bagasse as a floating seedling substrate, and seriously hinders the efficient use of bagasse as a renewable resource.
