Abstract

The invention discloses fertilizer capable of reducing lead pollution. The fertilizer is prepared from, by weight, 60-80 parts of charcoal, 20-30 parts of excrement of livestock, 10-12 parts of compound fertilizer, 10-12 parts of phosphorus pentoxide, 3-5 parts of potassium oxide, 2-4 parts of compound microorganism bacterium agent, 10-15 parts of potassium fulvic acid, 3-5 parts of cellulose and6-10 parts of auxiliaries. The fertilizer contains rich elements like nitrogen, phosphorus and potassium, and the nutrients needed for the growth of crops are effectively guaranteed; more importantly,potassium fulvic acid is polycondensate of a multivalence phenol-type aromatic compound and a nitrogen compound, and can be subjected to organic complexation and adsorption with lead ions, the activity of the lead ions is lowered, the absorption of the lead ions by the crops is effectively reduced, and the deposition of lead in tissue and organs of the human body is reduced.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a fertilizer capable of alleviating lead pollution. Background technique [0002] No matter in the fields of food crops or commercial crops, fertilization has been used for a long time to improve crop yield and quality. From the earliest application of farm organic fertilizers to the application of inorganic fertilizers, and then to the application of organic-inorganic compound fertilizers. Fertilizer type, fertilization amount and ratio have a great impact on the yield and quality of food crops or economic crops. Although traditional fertilizers, especially organic-inorganic compound fertilizers, have played a good role in increasing crop yields. However, traditional fertilizers have an unreasonable ratio of ingredients and nutrients, which can hardly restore soil fertility, improve soil structure, and even cause side effects, such as soil compaction. [0003] Fertilizers are compo...
