Abstract
Description
Technical Field
[0001] The invention relates to the technical field of fly maggot chitin microbial fertilizers, in particular to a fly maggot chitin microbial fertilizer and a production process thereof. Background Art
[0002] Housefly belongs to the class Insecta, order Diptera, suborder Cycloschisis, family Muscidae. It is the most common and largest species in most parts of my country. It has a short life cycle and strong reproductive ability. The larvae of houseflies are maggots. Maggots (dry basis) contain crude protein, fat, chitin, and various amino acids, and have relatively comprehensive nutritional components. At the same time, the larvae also contain more than 10 trace elements such as iron, zinc, and manganese, and have high utilization value. For example, in the production of maggot chitin microbial fertilizer, houseflies are generally cultivated using livestock and poultry manure.
[0003] At present, most of the existing maggot chitin microbial fertilizers and their production processes simply mix maggot chitin into fertilizers, and cannot use the livestock and poultry manure used to cultivate maggots into fertilizers. The livestock and poultry manure after cultivating maggots can only be composted. Composting is one of the important technical means for resource-based and harmless treatment of livestock and poultry manure, but the high water content of livestock and poultry manure is a bottleneck that hinders the rapid heating and fermentation of compost. Traditional methods for producing organic fertilizers must add a large amount of auxiliary materials such as sawdust and fermentation bacteria, which not only greatly increases production costs, but also takes a long time to ferment. In this way, the production of organic fertilizers requires a long factory turnover time, and mechanical turning and manual work are required during the fermentation process, which generates a large amount of electricity consumption, oil consumption, and labor costs. Therefore, the production cost is very high, which in turn increases the production cost of maggot chitin microbial fertilizers in disguise. Therefore, a maggot chitin microbial fertilizer and its production process are proposed to solve the above problems. Summary of the Invention

[0019] 7) The deproteinized shell residue is washed and dried to obtain a chitosan product;
[0020] 8) The protein solution produced by the deproteinization treatment is subjected to hydrochloric acid precipitation, and then filtered, washed, precipitated, and low-temperature dried in sequence to obtain a protein product;
[0021] 9) Take out the fecal waste after the fly maggots are cultured in 3) and spray 2-3 parts of the mixed bacteria into the fecal waste;
[0022] 10) adding the chitosan separated in 7) to the fecal waste, and fermenting the mixture for 5-7 days to obtain a secondary fermentation fertilizer;
[0023] 11) Drying and crushing the secondary fermented fertilizer to obtain powdered fly maggot chitin microbial fertilizer.
[0024] (3) Beneficial effects
[0025] Compared with the prior art, the present invention provides a fly maggot chitin microbial fertilizer and a production process thereof, which has the following beneficial effects:
[0026] The fly maggot chitin microbial fertilizer and its production process reduce the cost of chitin acquisition by using livestock and poultry manure to cultivate fly maggots, then mix the fly maggot chitin with the livestock and poultry manure used to cultivate the fly maggots for mixed processing to obtain the fly maggot chitin microbial fertilizer. The livestock and poultry manure is fully utilized to produce the fly maggot chitin microbial fertilizer. From the release of fly seeds to the maturity of the fly maggots, it only takes 5 days in summer and 7-8 days in winter. In this way, the time for producing organic fertilizer by processing manure from cultivated fly maggots is shortened by 15-20 days compared with traditional production methods, greatly reducing the processing time of livestock and poultry manure, thereby achieving the effect of greatly shortening the turnover time of the factory to reduce production costs.
