The present invention discloses an efficient and ecological organic fertilizer, which is formed by uniformly mixing the following raw materials by weight: 4-6 parts of powdery oil cake, 2-4 parts of phosphorite powder, 1-3 parts of nature potassium magnesium sulfate, and 2-4 parts of a natural organic acid solution. According to the present invention, the matching is simple, and simple powdery oil cake, the phosphorite powder and the nature potassium magnesium sulfate are mixed to form the efficient and ecological organic fertilizer, such that the processing difficulty can be reduced compared with other the organic fertilizers with multiple varieties, the nitrogen fertilizer content in the organic fertilizer and the seasonal utilization rates of the phosphorus fertilizer and the potassium fertilizer are improved, and the fertilizer efficiency is stable.
