Abstract

The invention discloses a fertilizer for adsorbing heavy metals and promoting formation of beneficial florae in greenhouse soil. The fertilizer for adsorbing heavy metals and promoting formation of beneficial florae in greenhouse soil comprises, by weight, 8-10 parts of ammonium nitrate, 8-12 parts of urea, 10-15 parts of potassium phosphate, 8-12 parts of a calcium magnesium phosphate fertilizer, 1-2 parts of zinc sulfate, 1-3 parts of potassium silicate, 0.4-0.6 parts of calcium chloride, 40-50 parts of a decomposed organic fertilizer, 8-10 parts of biochar, 10-15 parts of purple root water hyacinth root powder, 3-5 parts of functional bacteria and 1-3 parts of jasmomc acid. The fertilizer disclosed in the invention has the advantages of abundant nutrition, good heavy metal adsorption, promotion of growth and breeding of beneficial bacteria in order to form beneficial florae, increase of the activity of various enzymes, soil improvement, and improvement of the output and the quality of vegetables.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer that absorbs heavy metals and promotes the formation of beneficial bacteria in greenhouse soil. 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, there is a need to provide new fertilizers that improve soil problems and high levels of heavy metals. Contents of the invention [0003] Based on the technical problems existing in the background technol...
