The invention discloses aspen 
fertilizer which comprises the following raw materials, 20-40 parts of 
guano, 10-20 silkworm excrement, 5-15 parts of animal bone 
powder, 5-15 parts of broomcorn 
straw powder, 30-40 parts of 
wood processing saw dust, 15-25 parts of bean pulp, 10-20 parts of 
cottonseed meal, 5-15 parts of grain 
stillage, 10-20 parts of vinegar residue, 10-20 parts of 
traditional Chinese medicine dregs, 10-20 parts of castor roots, 5-15 parts of pagoda leaves, 10-20 parts of peach leaves, 20-30 parts of pine needles, 20-30 parts of cortex meliae, 10-20 parts of 
achnatherum inebrians, 20-30 parts of 
urea, 10-20 parts of 
calcium nitrate, 20-30 parts of 
magnesium chloride, 5-15 parts of 
magnesium acetate and 5-15 parts of 
zinc sulfate. The aspen 
fertilizer can improve the quality of aspens, an can improve 
soil structure at the same time, soil hardening due to that fact that chemical 
fertilizer is applied too much is avoided, organic materials of the soil are increased, and soil ecological balance is maintained. The added 
traditional Chinese medicine can expel, kill and prevent pests, 
pesticide consumption is reduced or avoided, the 
disease-resistant, pest-resistant and lodging-resistant capacity of the aspens is improved, and the aspen fertilizer has good economical and environmental benefits.
