Chicken manure fermentation organic fertilizer and preparation method thereof

Abstract

The invention relates to a chicken manure fermentation organic fertilizer and a preparation method thereof. The chicken manure fermentation organic fertilizer comprises the following raw materials in parts by weight: 40-50 parts of chicken manures, 40-50 parts of straw powder, 2-5 parts of agricultural enzyme microorganism, 3-8 parts of inorganic raw materials, 1.5-3 parts of mineral soils, and 1-2 parts of starches. By using the prepared chicken manure fermentation organic fertilizer, the manures can be completely decomposed in 7-10 days; moreover, the chicken manure fermentation organic fertilizer has the characteristics of short composting periods, high temperature rising speed, high temperature and high lasting property, small fertilizer efficiency loss, high content of compost humic acid and complete innocent treatment; moreover, pathogenic bacteria of organic materials can be effectively deodorized and killed.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a chicken manure fermented organic fertilizer and a preparation method thereof, belonging to the field of biological fertilizers. Background technique [0002] In the prior art, the fertilizer starter is a compound flora composed of various natural beneficial microorganisms such as bacteria, filamentous fungi, yeasts, and actinomycetes, and has a strong aerobic fermentation and decomposition ability. All kinds of chicken manure, pig manure, cattle and sheep manure, fallen leaves, sawdust, fur and other animal and plant waste, domestic garbage waste or all other organic materials that need to be treated can be treated in a harmless and resourceful manner. However, the functional strains in the fertilizer starter in the prior art have strict requirements on the ambient temperature, which needs to be above 10-15°C. [0003] The invention patent with the appl...

[0003] The invention patent with the application number 200710093109.4 discloses a fermented chicken manure fertilizer and its preparation method. In this application, the fertilizer consists of fresh chicken manure, bran powder, corn flour, wheat flour, brown sugar, lime powder, dinoflagellates, yeast, lactic acid bacteria, Made of high-temperature actinomycetes, etc., the application is fermented twice, the fermentation time is long, and the environment is harsh. The temperature of the first fermentation is 45-60°C, and the temperature of the second fermentation is 25-35°C. Due to the complicated steps , harsh conditions, increased capital investment; and the pH of the fertilizer is weakly alkaline, long-term use in alkaline soil will increase the compaction of the soil, which is not conducive to the adjustment of the soil

The invention patent with application number 201410399156.1 discloses a chicken manure organic fertilizer fermented by microorganisms, including chicken manure 45%-70%, bran powder 5%-20%, straw powder 15%-35%, EM stock solution 0.1%-2 %, bran 0.5%-4%, the investment cost of this patent is relatively high
