The invention relates to the technical field of chemical industry, and especially relates to a method for preparing dipotassium hydrogen phosphate and preparing a special fertilizer for spinach as a byproduct. The effective absorption amounts of N, P and K elements are analyzed according to fertilizer requirements of spinach, and the contents of elements in the production process are adjusted and matched to make the prepared compounded composite fertilizer maximally meet the demands of spinach, so the too high cost caused by improper matching of the elements in the production of the composite fertilizer is avoided, and environmental pollution caused by solidification of the composite fertilizer due to the addition of excess elements into soil is further avoided.
