Problems solved by technology

[0002] Fertilizers can provide the necessary nutrients for the growth of crops, but different fertilizers or similar fertilizers have different ratios of ingredients and different manufacturing processes, and the degree of absorption and utilization of them by crops is also different, and some of them lead to very slow absorption by crops. , and some cannot be directly absorbed at all, such as calcium magnesium phosphate fertilizer, which is a powdery phosphate fertilizer, which is difficult to apply, which is not conducive to manual operation, agricultural machinery operation, or granulation. Modern mechanical operations It becomes a problem; it is also a kind of citrus soluble fertilizer, insoluble in water, and it is difficult for crops to absorb it directly. After calcium magnesium phosphate fertilizer is applied to the soil, the

Embodiment 1

[0022] A kind of slow release phosphate fertilizer, its production method is as follows:

[0023] The phosphate rock containing 12%-16% phosphorus is crushed by a crusher into blocks with a diameter of 0.5cm-1.0cm, then dried by a dryer for 15 minutes, and then ground by a ball mill to a fineness of 90 -100 mesh phosphate rock powder for standby;

[0024] Mix 3 tons of chicken manure, 3 tons of distiller's grains, 4 tons of bagasse, 3 tons of coal gangue and 6.7 tons of sludge according to the proportion, and then perform high-temperature drying and sterilization treatment to control the water content of the mixture at 8 %-10%, and then the mixture is ground into a powder with a fineness of 90-100 mesh by a ball mill, and then the bacteria material is added to the above-mentioned powdered mixture and mixed evenly, and finally the above-mentioned mixture Pile it into the fermentation tank for fermentation. Control the temperature of the fermentation tank between 20-30 degrees ...

Embodiment 2

[0031] The difference between this embodiment and Example 1 is: a slow-release phosphate fertilizer, which, on the basis of ensuring the basic efficacy of this fertilizer, focuses on the advantages of the functional application of the biological bacteria slow-release agent, that is, in the biological bacteria slow-release agent. Within the value range of the weight ratio, the value tends to be maximized, so that this fertilizer can fully exert the functions of nitrogen fixation, phosphorus dissolution, and potassium dissolution, and can activate the solidified nitrogen, phosphorus, and potassium in the soil. , realize the unity of quick effect and long-term effect, and at the same time enhance the functions of salt resistance, drought resistance, lodging resistance, heavy cropping resistance and disease prevention and control of crops.

[0032] The present embodiment is made up of the raw material of following ratio: 0.50 ton of phosphate rock powder, 0.15 ton of biological bac...

Abstract

The invention discloses slowly released phosphatic fertilizer which consists of the following raw materials in parts by weight: 40-60 parts of powdered rock phosphate, 10-15 parts of biological bacterium controlled release agent, 20-40 parts of calcium magnesium phosphatic fertilizer and 7-10 parts of bentonite. The production method comprises the following steps of: firstly mixing powdered rock phosphate, the biological bacterium controlled release agent and calcium magnesium phosphatic fertilizer according to the ratio in parts by weight, then stirring uniformly, stacking and fermenting, finally adding bentonite into the fermented fertilizer, granulating by a rotary drum, and then packaging finished products. The slowly released phosphatic fertilizer disclosed by the invention has the advantages that the using quantity of the fertilizer is reduced; soil is modified, and the release speed of nutrients is regulated and controlled, and the integration of quick acting and long acting is realized; the pesticide use quantity is reduced, and the capabilities of salt resistance, drought resistance, lodging resistance, continuous cropping resistance of crops are intensified; and conditions for large modern mechanical operation are created.
