A kind of green environmental protection bio-organic fertilizer and preparation technology thereof

Abstract

The invention discloses a kind of environment-friendly bio-organic fertilizer. The environment-friendly bio-organic fertilizer comprises, by weight, 50 parts to 80 parts of duck manure, 20 parts to 30 parts of humic acid, 10 parts to 15 parts of straw, 5 parts to 10 parts of withered flowers and fallen leaves, 5 parts to 10 parts of filtered mud, 2 parts to 4 parts of plant ash, 5 parts to 8 parts of functional bacteria, 10 parts to 15 parts of corncobs, 5 parts to 10 parts of ground phosphate rock, 5 parts to 8 parts of maize meal, 1 part to 3 parts of zymogen agent, 1 part to 3 parts of coal gangue, 3 parts to 5 parts of neutral protease, 2 parts to 5 parts of plant growth accelerator, and 5 parts to 8 parts of deodorizing bacteria. According to the environment-friendly bio-organic fertilizer, because the duck manure, the straw, the corncobs, the filtered mud, the plant ash and the like serve as raw materials, environmental pollution is reduced, it is guaranteed that the soil structure is not destroyed, environment protection is achieved, soil fertility is effectively improved, the fertilizer can be easily absorbed by crops, producing cost is reduced, the virtuous circle of agricultural production is promoted, and economic benefit is increased comprehensively.

Description

technical field [0001] The invention relates to a green and environment-friendly bio-organic fertilizer and a preparation process thereof. Background technique [0002] At present, my country's aquaculture industry is developing rapidly, and is developing in the direction of specialization, scale and intensification. At the same time, there are more and more wastes in aquaculture archways. Duck manure contains a large amount of organic pollutants. COD alone has reached 71.18 million tons, which has far exceeded the sum of COD of industrial and domestic sewage pollutants. Faced with the severe problems of population increase and environmental degradation, the extensive use of inorganic fertilizers in agricultural production will also make environmental degradation more serious. The shortcomings of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, imbalances in the proportion of various nutrients, aci...

Problems solved by technology

However, the existing biological fermentation technology has the following disadvantages: long fermentation period, incomplete killing of harmful bacteria and insect eggs, low conversion rate of organic matter, low dehydration rate, and poor deodorizing effect
