Abstract

The invention discloses fertilizer capable of adsorbing heavy metal. The fertilizer comprises raw materials in parts by weight as follows: 15-20 parts of monopotassium phosphate, 5-8 parts of ammonium dihydrogen phosphate, 10-12 parts of urea, 5-8 parts of ammonium nitrate, 0.5-1 part of sodium silicate, 3-5 parts of humic acid, 10-15 parts of edible fungus chaff, 8-12 parts of oyster shells, 20-30 parts of corn stalks, 10-15 parts of cassava residues, 10-15 parts of furfural residues, 1-3 parts of an EM microbial agent and 15-25 parts of an additive. The fertilizer is rich in nutrients and capable of adsorbing heavy metal, preventing vegetables from absorbing the heavy metal and regulating the soil environment, thereby facilitating adsorption of the heavy metal and realizing good heavy metal adsorption effect; the fertilizer can also promote growth and propagation of beneficial bacteria, effective microbial community is further formed, the activity of various enzymes can be increased, the soil is improved, the yield of vegetables can be increased, and the quality of the vegetables can be improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for absorbing heavy metals. Background technique [0002] As people's demand for vegetables is increasing, people increase vegetable production by increasing the cultivation of greenhouse vegetables and increasing the amount of fertilization. However, extensive application of chemical fertilizers will aggravate soil acidification, compaction, and pests and diseases in the soil. The use of organic fertilizers can improve the soil, but long-term application of manure organic fertilizers will increase the content of heavy metals in the soil and affect the edible safety of vegetables. Therefore, it is necessary to provide new fertilizers to improve the problem of high heavy metal content in the soil. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a fertilizer that absorbs he...
