Organic fertilizer prepared by fermentation of fruit and vegetable slag and production technology thereof

Abstract

The invention relates to an organic fertilizer prepared by fermentation of fruit and vegetable slag and production technology thereof, belonging to the technical field of organic fertilizers. The raw materials of the organic fertilizer comprise, by weight, 400 to 1000 parts of one or more selected from the group consisting of apple slag, pear slag and vegetable slag, 600 to 1800 parts of sludge, 500 to 1000 parts of livestock manure and 0.5 to 1.5 parts of an activator. The production technology comprises the following steps: (1) respectively taking the above-mentioned raw materials according to desired parts and evenly mixing the raw materials; (2) piling the mixed raw materials into a certain shape or putting the mixed raw materials into a fermenting tank for fermentation; (3) evenly overturning the fermenting raw materials every 40 to 50 hours and overturning three to four times so as to obtain the bio-fertilizer after the fermentation is finished. The advantages of the invention are as follows: the waste things are turned into the valuable; the obtained bio-fertilizer is rich in nutriments, has high fertilizer efficiency, and enables environmental pollution resulted from the deterioration and decay of fruit and vegetable slag to be avoided.

Description

1. Technical field [0001] The invention relates to an organic fertilizer prepared by fermenting fruit and vegetable dregs and a production process thereof, belonging to the technical field of organic fertilizers. 2. Background technology [0002] my country's annual fruit output reaches 250 million tons, of which about 38% is used for deep processing. At present, a wide variety of fruit juices and vegetable juices are flooding the beverage market. With the development of fruit planting and processing industries, the output of pomace has increased significantly. Pomace is a by-product obtained from the process of fruit juice or canning, mainly fruit pulp, fruit stone, fruit peel, etc. According to each processed 1000kg fruit, It can produce 300-500kg of fresh pomace and 120-165kg of dried pomace after drying. There are about tens of millions of tons of pomace resources in the country every year. Fruit and vegetable pomace contain a large amount of nitrogen, phosphorus, potassi...

With the development of the fruit planting and processing industry, the production of pomace has increased significantly. Pomace is a by-product obtained from the process of fruit juice or canned production. It can produce 300-500kg of fresh pomace and 120-165kg of dried pomace after drying. There are about tens of millions of tons of pomace resources in the country every year. Fruit and vegetable pomace contain a large amount of nitrogen, phosphorus, potassium, organic matter, humic acid and other substances. However, there is still a lack of effective means for the comprehensive utilization and development of pear pomace, apple pomace, and vegetable pomace at present. Except for a small amount of being used for deep processing, the pomace in most fruit juice factories in my country has not been well utilized. The water content is high, and it is easy to be spoiled and deteriorated. It is a relatively conventional treatment method to pile up, landfill or directly discard, and let it rot and deteriorate. This will not only seriously pollute the environment but also cause a waste of resources, and also affect the sustainability of the fruit industry develop
