Problems solved by technology

[0002] Among the currently known nutrients required by crops, the effects of nitrogen, phosphorus, and potassium are well known. They are basically chemical fertilizers, which are high-content quick-acting fertilizers made by chemical methods. The main disadvantage is that they are used in large quantities. Under normal circumstances, the soil will be compacted, the soil fertility will decline, and finally a large amount of resource waste will be caused; while the existing organic fertilizers (commonly known as farmyard manures) have long fertilizer effects, but are not suitable for topdressing, and their relative fertility is poor; therefore, compound fertilizers are currently the best choice for fertilizers. A major development trend, to overcome the shortcomings of chemical fertilizers that have a single component and cannot meet the overall needs of crops, especially the existing compound fertilizers lack a variety of trace elements, so how to choose a suitable ratio so that compound fertilizers can be used as base fertilizers It can also be used as top dressing and improve the soil, which is a new direction and subject of fertilizer development

Embodiment 1

[0007] The present invention is further specified by the following examples: 50 parts of steamed bone meal, 20 parts of peat powder, 5 parts of concentrated sulfuric acid, 10 parts of water and 30 parts of ammonium nitrate are stirred evenly, and then enter the fermentation tank or tank for fermentation for 7 days. The fermentation temperature is controlled at about 50 degrees Celsius. The above-mentioned fermented mixed material is mixed with 30 parts of phosphate rock powder containing more than 30% phosphorus, granulated, and dried to form the bone meal compound fertilizer, which can be packaged according to specific conditions. library. The above-mentioned bone meal compound fertilizer is particularly suitable for crops such as forest fruit, rice, and vegetables.

Embodiment 2

[0009] 50 parts of steamed bone meal, 20 parts of peat powder, 5 parts of concentrated sulfuric acid, 10 parts of water and 30 parts of urea are stirred evenly, and put into a fermentation tank or tank for fermentation for 7 days. The fermentation temperature is controlled at about 50 degrees Celsius. The final mixed material is mixed with 30 parts of phosphate rock powder containing more than 30% phosphorus, granulated, and dried to become the bone meal compound fertilizer, which is packed and put into storage according to specific conditions. The above-mentioned bone meal compound fertilizer is particularly suitable for crops such as wheat, corn, peanuts, and cotton.

[0010] The production steps of the steamed bone meal are as follows: put animal bones into a pressure tank, add steam to the pressure tank with a steam boiler, and raise the pressure to 0.6-2 MPa / cm 2 , kept for 2-3 hours, at this time, the temperature in the pressure tank was kept at 110-130 degrees Celsius, ...
