The invention belongs to the technical field of a fertilizer, and in particular relates to a chromium-rich specialized foliar fertilizer characterized by comprising the following raw materials by weight: 25-35 parts of chromium (III) trichloride, 15-25 parts of urea, 5-15 parts of potassium dihydrogen phosphate, 10-20 parts of potassium oxide, 10-12 parts of boron, 8-10 parts of zinc, 3-5 parts of manganese, 0.5-1.5 parts of copper, 1-2 parts of iron and 0.1-0.3 part of molybdenum. Compared with the prior art, the chromium-rich specialized foliar fertilizer has the fertilizer-medicine double effect, is full in nutrition components, high in concentration, low in cost, non-toxic, remarkable in disease and disaster prevention effect, convenient to use, great in yield increasing extent, and suitable for a variety of soil and crops for application and the like. The content of the main elements of nitrogen, phosphorus, potassium, chromium and the like in the chromium-rich specialized foliar fertilizer is high, after application of the crops, the chromium content is greatly improved, and the chromium-rich specialized foliar fertilizer plays a good role to promote crop growth and increase stress resistance.
