Embodiment 1

[0059] (1) Bacterial solution preparation: prepare Bacillus subtilis purchased from the market with an effective viable concentration of 100 billion / g: white sugar: process water at a ratio of 1:5:4 to make a bacterial solution with a viable concentration of 10 billion / g and heat before use To 50 ℃, it is a liquid with good flow;

[0060] (2) The bare fertilizer of 15-15-15 nitrosulfur compound fertilizer produced by China-Arabian Fertilizer Co., Ltd., after being cooled by the fluidized bed, enters the fertilizer anti-caking wrapping tube, and drips 10 billion / g bacterial powder aqueous solution 5.0 kg / ton of fertilizer, then evenly add anti-caking powder 3.0 kg / ton of fertilizer, and then dropwise add anti-caking oil agent 2.0 kg / ton of fertilizer preheated to 80-100 ° C, later, the finished product The chemical fertilizer flows out of the anti-caking packaging tube and enters the finished product warehouse; the synergistic fertilizer has a good appearance, uniform color, n...

Embodiment 2

[0063] (1) Bacterial solution preparation: prepare Bacillus subtilis purchased from the market with an effective viable concentration of 100 billion / g: white sugar: process water at a ratio of 1:2:2 to prepare a bacterial solution with a viable concentration of 20 billion / g and heat before use To 50 ℃, it is a liquid with good flow;

[0064] (2) The 15-15-15 nitrosulfur-type compound fertilizer bare fertilizer produced by China-Arabian Fertilizer Co., Ltd., after being cooled by a fluidized bed, enters the fertilizer anti-caking wrapping tube, and drips 20 billion / g bacterial powder aqueous solution 5.0 kg / ton of fertilizer, then evenly add anti-caking powder 3.0 kg / ton of fertilizer, and then dropwise add anti-caking oil agent 2.0 kg / ton of fertilizer preheated to 80-100 ° C, later, the finished product The chemical fertilizer flows out of the anti-caking packaging tube and enters the finished product warehouse; the synergistic fertilizer has a good appearance, uniform color...

Embodiment 3

[0067] (1) Bacterial solution preparation: prepare Bacillus subtilis purchased from the market with an effective viable concentration of 100 billion / g: white sugar: process water at a ratio of 1:2:2 to prepare a bacterial solution with a viable concentration of 20 billion / g and heat before use To 50 ℃, it is a liquid with good flow;

[0068] (2) The large-grain urea produced by China BlueChemical Co., Ltd. is put into the fertilizer anti-caking wrapping tube, and 5.0 kg / ton of 20 billion / g bacterial powder aqueous solution in step (1) is added dropwise, and then preheated to 80 ~100℃ anti-caking oil agent 2.0 kg / ton fertilizer, after a while, the finished product flows out of the chemical fertilizer anti-caking package tube and enters the finished product warehouse; the synergistic fertilizer has a good appearance, uniform color, touches without any powdery feeling, The theoretical viable count of compound fertilizer is 100 million / g fertilizer.

Abstract

The invention discloses biological agent synergized inorganic fertilizer and a preparation method thereof, and belongs to the technical field of agricultural fertilizer. The method comprises the following steps: firstly, preparing a microbial agent, an organic protective carrier and process water into a flowable bacterial solution; secondly, sequentially coating the surface of granular inorganic fertilizer with the bacterial solution in the first step, anti-caking powder and an anti-caking oil agent in a fertilizer anti-caking packaging barrel to form the biological agent synergized inorganicfertilizer. The preparation method of the biological agent synergized inorganic fertilizer disclosed by the invention has the advantages that the biological agent synergized inorganic fertilizer withuniform coating and no risk of bacterial powder falling is obtained without any disturbance to the production process of fertilizer; in addition, the organic protection carrier in the bacterial solution coating can play dual roles of a microbial agent, protector and a plant growth stimulant.

Description

technical field [0001] The invention relates to a biological bacterial agent synergistic inorganic fertilizer and a preparation method thereof, belonging to the technical field of agricultural fertilizers. Background technique [0002] Fertilizers, especially chemical fertilizers, are a source of nutrients necessary for crop growth. However, with the extensive use of chemical fertilizers, especially long-term excessive fertilization and lack of timely replenishment of soil organic matter, soil compaction and acidification have been caused, soil fertility has decreased, the number of beneficial bacteria has decreased, and the natural ecological environment has deteriorated. To solve this problem, on the one hand, it is necessary to fertilize rationally, on the other hand, it is to replenish soil organic matter in a timely manner. At the same time, the development of environmentally friendly, value-added and synergistic fertilizers is also one of the effective ways to achieve ...
