Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, and specifically discloses an organic fertilizer for walnut saplings. Background technique [0002] Walnut is one of very nutritious nuts, and the planting area of ​​walnut saplings in my country is increasing, and the output of existing organic fertilizers for planting walnut saplings is low, which cannot meet the agricultural needs of the development of the mouth, and in the prior art Some of the planted walnut saplings contain pesticide residues, which are harmful to the health of consumers to a certain extent. In the soil with excessive application of chemical fertilizers, the content of inorganic matter soars, organic matter weakens, trace elements are unbalanced, and crop diseases and insect pests become more and more serious. A large amount of chemical fertilizers are leached into groundwater or into lakes with rainwater, causing secondary pollution to the environment. [0...
