Abstract

The invention relates to a method for preparing fertilizer granules. The method comprises the steps of feeding a mixture of farmyard manure, raw bone meal and sewage into a first fermentation tank toobtain first fertilizer powder; mixing a nitrogen fertilizer, borax and clay into nitrogen fertilizer powder to obtain second fertilizer powder; crushing straw powder, grass ash, rice hull powder, soybean meal and potatoes and feeding the mixture into a second fermentation tank to obtain third fertilizer powder; mixing a phosphorus fertilizer, zinc sulfate and the clay into phosphate fertilizer powder to obtain fourth fertilizer powder; feeding straws, rice bran and a river mud mixture into a third fermentation tank to prepare fifth fertilizer powder; mixing a potassium fertilizer, yellow humic acid and the clay into potassium fertilizer powder to obtain sixth fertilizer powder; feeding the first fertilizer powder, the second fertilizer powder, the third fertilizer powder, the fourth fertilizer powder, the fifth fertilizer powder and the sixth fertilizer powder into a granulator successively, and spraying a bonding solution into the granulator to obtain the fertilizer granules. According to the method, the combination of inorganic fertilizers and organic fertilizers is achieved, and the organic fertilizers and the inorganic fertilizers are alternately superposed to form the fertilizer granules, and the nutritional demand of crop growth can be met.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a method for preparing fertilizer granules. Background technique [0002] With the continuous development of science and technology and the continuous innovation of agricultural technology, all kinds of agricultural machinery have been widely used in large-scale and large-scale farmland. In order to facilitate mechanized fertilization, granular fertilizer has become the development trend of chemical fertilizers today, because it is more Powdered fertilizer has the advantages of good physical properties, no dust during loading and unloading, no caking during long-term storage, good fluidity, easy to spread evenly during fertilization, and easy to realize mechanical fertilization. In addition, after the powder fertilizer is directly applied to the soil, the nutrients are released too quickly, which is easy to burn the crops, and the nutrients that are not absorbed and utilized in time ar...
