Method for preparing special-purpose eucalyptus organic compound fertilizer by utilizing fermenting waste

Abstract

The invention discloses a method for preparing a special-purpose eucalyptus organic compound fertilizer by utilizing fermenting waste. The method comprises the following steps of: (1), concentrating, namely concentrating molasses fermenting waste liquor, wherein one part of the wastewater is used for alkaline hydrolysis and dehydration, and the other part of the wastewater is used for acid hydrolysis and dehydration; (2), carrying out alkaline hydrolysis and dehydration, namely adding an alkaline hydrolysis agent in the concentrated liquor, and stirring at a low speed to obtain alkaline hydrolysis seasoning; (3), carrying out acid hydrolysis and dehydration, namely adding an acid hydrolysis agent in the concentrated liquor, and stirring at a low speed to obtain acid hydrolysis seasoning; and (4), preparing neutralization seasoning, namely mixing the acid hydrolysis seasoning and alkaline hydrolysis seasoning to generate acid-alkali neutralization, drying, carrying out multi-stage biological fermenting retting, and regulating pH to obtain the active compound organic fertilizer. According to the method disclosed by the invention, a method of combining an acidification process and an alkalization process is adopted, a modern fermentation biological technology is combined, and fermenting waste after non-noxious treatment is used for preparing the special-purpose eucalyptus fertilizer, and therefore, technical problems such as multi-element deficiency of eucalyptus, soil hardening and poor disease resistance in the prior art are solved, and character and quality of the eucalyptus are improved.

Description

technical field [0001] The invention belongs to the field of industrial waste recycling and relates to a method for preparing special organic compound fertilizer for eucalyptus by using fermentation waste. Background technique [0002] Eucalyptus is the general name of Eucalyptus species in the family Myrtaceae, and its Latin name is Eucalyptus, which is native to Australia, Indonesia and the Philippines. Eucalyptus has been introduced to my country for more than 110 years, and it has become a strategic tree species for fast-growing and high-yield forests in southern my country. In 2002, according to the statistics of relevant departments, the area of ​​eucalyptus plantations in the world was 18 million ha 2 , accounting for about 25% of the area of ​​tropical plantations, providing 180 million m of timber per year 3 , China's eucalyptus plantations account for 12% of the world's total, or 1.5 million hm 2 , mainly distributed in Guangxi, Guangdong, Yunnan, Hainan, Fujian...

Problems solved by technology

[0008] The purpose of the present invention is to aim at the incomplete harmlessness of molasses fermentation waste liquid used in fertilizer production in the prior art, the single humification acidification or alkalization process, resulting in poor humification effect and incomplete humification, Fertilizers containing molasses fermentation waste liquid cause secondary pollution to the soil during use, fertilizers have no effect on crop growth, etc. Eucalyptus salt fertilizers pollute the soil, and a method for preparing organic compound fertilizers for eucalyptus using fermentation waste is provided , the method proposes the combination of acidification and alkalization, the concentrated liquid of molasses fermentation waste liquid is subjected to acid and alkali humification respectively, and then the two are moderated and neutralized so that the fermented waste liquid after humification can be used for Prepare a variety of organic / inorganic mixed compound fertilizers. The organic / inorganic mixed compound fertilizer uses modern microbial technology, inoculates biological bacteria, and undergoes multi-stage fermentation culture. According to the law of eucalyptus's intake of trace elements, efficient compound microbial fermentation can be produced. agent; coupled with the ash and filter mud produced in the production of alcohol waste liquid as a substrate, a fixed and high-efficiency biological fertilizer suitable for the robust growth of eucalyptus was developed
