The present invention relates to a mountain fruit tree nutrition liquid, which comprises, by weight, 200-220 parts of urea, 150-170 parts of potassium nitrate, 60-80 parts of zinc phosphate, 30-40 parts of copper sulfate, 10-20 parts of ferrous sulfate, 15-20 parts of magnesium sulfate, 10-15 parts of manganese sulfate, 15-20 parts of borax, 7-10 parts of ammonium molybdate, and trace components. The mountain fruit tree nutrition liquid of the present invention contains amino acids, plant growth hormones and trace elements, and can have effects of gradual plant rhizosphere soil pH value adjusting, microorganism activity increase, organic matter decomposition accelerating, soil pellet structure improving, and fertilizer utilization rate improving. In addition, the trace components of the invention are the trace elements, such that the good growth of the fruit tree can be promoted, the trace element content in the fruit can be increased, and the fruit nutrition can be increased.
