Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] see figure 1 , a kind of method that utilizes green foxtail algae to cow dung composting, is prepared according to the following steps:

[0024] S1. Weighing the compost raw materials required for composting: the compost raw materials are composed of fresh green foxtail, cow dung, straw, sawdust and waste biomass carbon, and the green foxtail, cow dung, straw, sawdust The addition ratios of biochar and waste biochar are 30% to 70%, 12% to 52%, 5%, 10%,...

Abstract

The invention relates to the technical field of fertilizer processing, and discloses a method for composting cow dung by using myriophyllum elatinoides gaudich. The cow dung is prepared according to the following steps that S1, compost raw materials required for composting are weighed; S2, preparation of complex microbial agents is performed; and S3, mixing and composting are performed. The linkssuch as mechanical dehydration or natural dehydration of traditional aquatic plant compost are eliminated, the workload and site are reduced, meanwhile, the resource utilization of aquatic plants is realized, so that the harvested aquatic plants can be used as compost raw materials, the workload and the economy cost of subsequent processing of the aquatic plants are reduced, and secondary pollution is avoided; and the raw materials used for composting are agricultural production waste, and waste recycling is realized. The prepared organic fertilizer has good fertilizer effect, the organic matter content (dry weight) reaches 45% or above, the total primary nutrient (dry weight) reaches 5% or above, and the moisture (fresh weight) is 30% or less. The killing rate of alien species of ova of roundworm and escherichia coli is 95% or above, the content of heavy metals (based on drying basis) is lower than the limit standard, and the national standard for organic fertilizers (NY525-2012) canbe met.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a method for composting cow dung by using viridiflora. Background technique [0002] With the rapid development of animal husbandry in my country, the pollution caused by livestock and poultry manure to the environment is becoming more and more serious. Generally, cattle farms mainly carry out harmless treatment through anaerobic fermentation and composting fermentation. Since anaerobic fermentation is limited by the capacity of the device, it is not suitable for large-scale farms. Since the moisture content in the cow dung is above 80%, this affects the gas permeability of the cow dung and the activity temperature of the natural fermentation bacteria in the cow dung, prolonging the fermentation period of the cow dung. At present, domestic cow dung composting mostly uses methods such as adding straw and rice husk to absorb water and increase air permeability. This ...
