Multi-antibiotic organic bacterial fertilizer and preparation method thereof

Abstract

The invention relates to an organic bacterial fertilizer belonging to the technical field of agricultural production, and particularly relates to a functional multi-resistant biological organic bacterial fertilizer promoting growth of farm crops and cash crops. The multi-resistant biological organic bacterial fertilizer is prepared through the following steps: preliminarily mixing fresh cattle manure, fresh sheep manure, fresh chicken manure and powdery plant straws according to a certain volume ratio, then admixing with multiple biological bacteria and minor elements, and fermenting. According to the invention, the formula of the multi-resistant biological organic bacterial fertilizer chooses the organic raw materials which contain natural active substances and decomposition products and can inhibit and reduce soil-borne diseases; and meanwhile, the biological florae secrete multiple antibiotics and plant active substances, the enriched multiple fatty acids and antibiotics can obviously inhibit and relieve the soil-borne diseases of the crops, and the comprehensive nutrients improve the disease resistance of the crops. Thus, the fertilizer has better antibacterial and disease-resistant effects.

Description

technical field [0001] The invention relates to an organic bacterial fertilizer, which belongs to the technical field of agricultural production, in particular to a functional multi-antibiotic organic bacterial fertilizer for promoting the growth of crops and economic crops. Background technique [0002] With the advancement of science and technology in the field of microorganisms, agricultural scientists generally believe that fertilizers should be developed in the direction of high efficiency and compounding, that is, a new type of fertilizer should be sought, which not only uses nitrogen, phosphorus, potassium and trace elements in combination, but also combines chemical fertilizers, microorganisms Combining fertilizer and organic fertilizer to give full play to the overall advantages to establish a benign farmland ecological cycle system and a comprehensive crop nutrition system to make full use of the soil potential. At present, in the field of crop cultivation, on the ...

Problems solved by technology

At present, in the field of crop cultivation, on the one hand, due to successive years of large-scale fertilization, especially unbalanced and unreasonable fertilization, negative effects have gradually emerged, such as eutrophication of water bodies, soil compaction, deterioration of the taste of vegetables and fruits, and increased incidence of diseases. Serious waste of energy, etc.; on the other hand, soil-borne diseases caused by continuous cropping, improper fertilization and nematode infestation have not only become the main technical problems affecting the development of high-efficiency agriculture in China, but also the main obstacles in the production of solar greenhouses and off-season cultivation. The control effect is less than 30%

According to research, the culprit of soil-borne diseases is the pathogens in the soil cultivation layer, because they are distributed in different positions of the soil, as long as the host plants appear, these dormant pathogens will germinate and affect plant growth by producing toxins, Attack the root system of the plant and enter the plant body, resulting in plant disease or death. Pesticide control is difficult to eliminate these germs in the soil. Although soil disinfection is a relatively good method, it is difficult to do in actual production. The reason is that The diseased soil area is large and the amount is wide, the cost of comprehensive soil disinfection is high, and the operation is difficult, which is almost impossible
