Problems solved by technology

However, adding lime will easily cause the pH of the organic fertilizer to be too high at the initial stage of fermentation, which will have a great impact on the reproduction and growth of microorganisms; on the other hand, aeration or turning over the pile will cause a large amount of water to evaporate, which is not conducive to the growth of microorganisms, and there is still a lot of CO 2 、CH 4 , NH 3 、H 2 S and nitrogen oxides and other gas volatilization phenomenon

Abstract

The invention discloses a mineral additive for promoting organic fertilizer fermentation. The main component of the mineral additive is 70-95% of gamma-dicalcium silicate. The preparation method comprises the following steps of: (1) material preparation: grinding a calcareous material and a siliceous material to fineness of 150-300 meshes; (2) firing: mixing the calcareous material and the siliceous material according to a ratio of CaO to SiO2 of 2-2.5, and performing firing for 0.5-3 hours at the temperature of 1150-1450DEG C; and (3) grinding: cooling the fired material, and performing grinding to 80-200 meshes to obtain the mineral additive. The mineral additive can slowly improve the pH change of the organic fertilizer in the fermentation process in a long-acting manner, increases thecontent of nutritional ingredients in the organic fertilizer, can adsorb a large amount of CO2, CH4, NH3, H2S, nitric oxide and other gases through a chemical reaction, and reduces the influence of organic fertilizer fermentation on the climate environment to a certain extent.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a mineral additive for promoting the fermentation of organic fertilizer. Background technique [0002] At present, the main method of organic fertilizer fermentation is to use microorganisms to carry out aerobic fermentation. During the fermentation process, a large number of small molecule organic acids, CO 2 、CH 4 , NH 3 、H 2 S and nitrogen oxides and other gases. On the one hand, these fermentation intermediates lead to a decrease in pH during the fermentation process of organic fertilizers, and low oxygen content in the compost, which greatly affects the activity of microorganisms and prolongs the fermentation time of organic fertilizers; on the other hand, the CO produced during the fermentation process 2 、CH 4 , NH 3 、H 2 The volatilization of gases such as S and nitrogen oxides reduces the nutrient content of organic fertilizers, and at the sam...
