Method for producing wormcast culture medium through sugar refinery waste

Abstract

The invention discloses a manufacturing method for producing a wormcast culture medium through sugar refinery waste. The method comprises the steps that after broken bagasse and sugarcane filter mud are fermented and composted, 10-100 kg of waste molasses is added into per cubic meter of materials, 0.5-0.9 mg/L of sodium selenite is added, larger than 2.0*10<7> cfu/g of bacillus subtilis is added, uniform stirring is performed, the water content is adjusted to be 40-75%, then, earthworm seeds are inoculated, and earthworms and wormcast are separated after reproduction is performed for a period of time. According to the prepared culture medium, the element absorptivity, the utilization rate and the safety of crops are greatly improved, the culture medium is environmentally friendly, the emergence rate and the survival rate are higher than those of a common culture medium, and the method is suitable for most crops, even flowers with the strict requirement for the culture medium. The method is easy to implement, high in resource utilization rate and relatively low in environment pollution.

Description

technical field [0001] The invention relates to a method for producing a vermicompost cultivation substrate by utilizing sugar factory waste materials. Background technique [0002] Vermicompost can be used as new biological fertilizers, adsorbents, deodorants, antidotes, etc., but many researches are still in the stage of laboratory testing, lacking field trials and actual effective applications. Vermicompost, as a by-product of vermiculture, has been in a sluggish domestic sales situation, and it can only be sold as general organic fertilizer (and processed to meet the organic fertilizer index) instead of a cultivation substrate. Its good cultivation function has not been developed. High-end products can only be sold as low-end organic fertilizers, so there is a certain gap between the price and the international market. At present, the deep processing of vermicompost is insufficient, and most enterprises only simply process and sell vermicompost, which makes most vermicu...

Problems solved by technology

Although the comprehensive utilization of waste from sugar factories in my country, such as bagasse, has made great progress, there are still some deficiencies. At present, an unreasonable phenomenon common in all sugar factories is that there is a large amount of bagasse remaining on the production side of the cropping season. , while still needing to be burned, stolen

In addition, fresh bagasse is irregular loose particles with low density and poor combustion characteristics, which is inconvenient for transportation, storage and use, which restricts the use of bagasse as a biomass energy source.

[0005] Invention patent "a selenium-enriched organic fertilizer based on vermicompost" (201310480212X), which uses a mixture of urban sludge, cow dung, and inorganic selenium as erbium material for earthworms, and uses the enrichment of earthworm metabolism to convert it into rich organic fertilizers. Selenium vermicompost, and finally add bacteria on the basis of vermicompost to process it into organic fertilizer". Generally speaking, 80% of urban sludge is used as the main raw material to match other raw materials and then feed vermicompost to make vermicompost , which often has a high failure rate due to high pH and heavy ammonia smell after fermentation. The most important thing is that the patent covers the pile with plastic cloth to make it into retting instead of composting, which will inevitably lead to anaerobic materials. Fermentation produces a state of high pH, ​​heavy ammonia smell,
