Description

technical field [0001] The invention relates to an agricultural fertilizer and a production method thereof, in particular to a compound potassium dihydrogen phosphate solution and a production method thereof. Background technique [0002] At present, most of the agricultural foliar spray fertilizers are solid potassium dihydrogen phosphate, and there are also some powders prepared by the principle of metathesis, and polybasic potassium dihydrogen phosphate liquid using sodium nitrophenolate as the penetrating agent, but due to poor solubility and fertilizer efficiency Factors such as incompleteness lead to its poor effect. Contents of the invention [0003] One of the purposes of the present invention is to provide a kind of fast absorption of crops, avoid antagonism, and improve the composite potassium dihydrogen phosphate solution of fertilizer efficiency; [0004] The second object of the present invention is to provide a method for producing the above-mentioned fertil...
