Embodiment Construction
[0024] As shown in the figure, the production method of biological controlled release fertilizer of the present invention comprises the following steps:
[0025] The first step is to produce film-forming materials:
[0026] 1. Add 1.0kg of fungal spore powder PPF to 2.0kg of caramel color (JTS) and 2.5kg of 80°C hot water mixture, stir evenly to make a coating material solution, and transport it to the storage tank;
[0027] 2. Take the organic matter carrier and place it in the granulation tray. After the granulation tray is started, turn on the air compressor to atomize the coating material and then spray it to the organic matter in the granulation tray through the sprayer. on the surface of organic particles;
[0028] 3. The organic granules attached to the coating material enter the conveyor belt through the lower part of the granulation disc, and then transfer to the air-drying barrel for heating and drying. The heating temperature is 140-200°C, and the heating time is 3...

The invention discloses a biological controlled released fertilizer. A production method of the fertilizer comprises the following steps of: 1, producing a film-forming material; and 2, producing the biological controlled released fertilizer. According to the production method, traditional liquid bacillus is changed into fungal spore powder. The fungal spore powder does not contain cell sap, and has good dormancy, so that death caused by loss of cell sap does not exist. The fungal spore powder is prepared into a coated material and can be used for coating an organic carrier to obtain a film-forming material containing the fungal spore powder, and then the film-forming material is evenly mixed with an inorganic constituent to generate the biological controlled released fertilizer which is subjected to controlled release in the whole growth period of a plant. By adopting the biological controlled released fertilizer prepared by the method disclosed by the invention, the utilization rate of the fertilizer can be greatly improved, the fertility of soil can be cultivated, the rhizosphere soil environment of the plant can be improved, and acidification, alkalization and salinization of the soil can be alleviated.
Description
technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a method for producing biological controlled-release fertilizers. Background technique [0002] Agriculture is the basic industry of our country, and the level of agricultural development and benefits are directly related to the quality of life of hundreds of millions of farmers. Our government has always attached great importance to agricultural issues. The 18th National Congress of the Communist Party of China listed promoting agricultural development, building a harmonious society, and comprehensively solving the "three rural" issues as national priorities. [0003] Chemical fertilizers have made outstanding contributions to the high and increased production of my country's agriculture. At present, the average contribution rate of chemical fertilizers in agriculture in my country is about 38%, ranking first among production materials such as seeds, pesticide...
