Abstract

The invention brings forward a composite biofertilizer and its preparation method. The preparation method comprises the following steps: 1) 20-40 parts by weight of domestic sludge and 0.1-0.2 part by weight of a fermented culture are mixed uniformly; 2) the above uniformly-mixed fermented culture undergoes aerobic fermentation and then is uniformly mixed with 0.1-0.2 part by weight of nitrogen, phosphor and potassium nutrient elements; 3) the above uniformly-mixed materials undergo granulation; and 4) particles obtained by the granulation undergo drying and cooling processes and then mixed with 0.15-0.25 part by weight of biological probiotics, so as to obtain the composite biofertilizer. According to the invention, the problem that sludge pollution is caused, soil structure is damaged and biodiversity in nature and ecosystem stability are reduced in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a compound biological fertilizer and a preparation method thereof. Background technique [0002] The report of the Seventeenth National Congress of the Communist Party of China pointed out: "We must strengthen energy and resource conservation and ecological and environmental protection, and enhance the ability of sustainable development. Adhering to the basic national policy of saving resources and protecting the environment is related to the vital interests of the people and the survival and development of the Chinese nation. A resource-saving and environment-friendly society should be placed in a prominent position in the development strategy of industrialization and modernization. It is necessary to improve the laws and policies that are conducive to saving energy resources and protecting the ecological environment, and speed up the development of sustainable devel...
