Composite fermentation microbial inoculant and application of composite fermentation microbial inoculant in preparation of citrus pulp bio-organic fertilizer

Abstract

The invention discloses composite fermentation microbial inoculant and an application of the composite fermentation microbial inoculant in preparation of a citrus pulp bio-organic fertilizer. The composite fermentation microbial inoculant includes fertilizer fermenting zymocyte, bacillus subtilis, enterococcus faecalis and trichoderma. The composite fermentation microbial inoculant can ferment organic waste having a main raw material of citrus pulp to obtain the biological organic fertilizer. A preparation method of the citrus pulp bio-organic fertilizer provided by the invention is simple inoperation, low in operation cost, good in product effect, can be promoted and applied on a large scale, can not only realize harmless treatment of the citrus pulp, solve environmental pollution problems, but also realize the recycling of the agricultural waste, and has good economic and ecological benefits; and the conventional nutrient indicators of the obtained bio-organic fertilizer meets the standards of Bio-Organic Fertilizer Standards of ''Agricultural Industry Standards of the People's Republic of China (NY 525-2012)'', and the bio-organic fertilizer is rich in nutrients, and can effectively improve soil, promote plant growth, enhance plant disease resistance, and improve the quality of agricultural products.

Description

technical field [0001] The invention belongs to the technical field of agricultural soil fertilizers, and in particular relates to a composite fermentation bacterial agent and its application in preparing citrus pulp bio-organic fertilizers. Background technique [0002] Citrus is the fruit with the largest production in the world, accounting for 20% of the world's total fruit production. In China, citrus is the fruit with the second highest yield in China. A large number of citrus are planted in Guangdong Province every year, mainly distributed in the area of ​​the Pearl River Triangular Pillar, especially in Xinhui, Jiangmen City, where a large number of tea oranges are planted every year. , After storage and aging, it is made into the well-known Xinhui tangerine peel. The peeled mandarin orange meat is large and cheap, except for a small amount of food, the rest are discarded. In traditional methods, except for a small amount of citrus pulp used for feed, beverage and o...

Problems solved by technology

In order to adjust the pH of the material to be suitable for microbial fermentation, the patents CN10396235, CN104892281 and CN108640781 adjust the pH value of citrus peels to 6.5-8 by adding lime powder or quicklime, but the prepared organic fertilizer is easy to cause calcification and alkalization of the soil

Patent CN103833467B discloses a citrus peel organic compound fertilizer and its preparation method, which uses microbial fermentation to reduce acidity and reduce the acidity of citrus peel, avoiding soil calcification and alkalization caused by the use of quicklime, but the acid-reducing microbial pretreatment requires 24~ 72h, the fertilizer production cycle is long, and the preparation method has complicated process, high operating cost, and long production cycle, which is not conducive to large-scale popularization and application

[0005] It can be seen that the effect of applying the existing technology to process citrus pulp is not ideal enough, therefore, it is urgent to develop a new method for large-scale processing of citrus pulp to produce bio-organic fertilizers, so as to remove cellulose, pectin, and protein from citrus pulp. and other macromolecular components are converted into small molecule nutrients for plant growth, so that the citrus pulp is completely degraded
