Sweet potato residue and chicken manure fertilizer and preparation method thereof

Abstract

The invention discloses a sweet potato residue and chicken manure fertilizer and a preparation method thereof. The sweet potato residue and chicken manure fertilizer is characterized by being prepared from the following raw materials in parts by weight: 200-300 parts of sweet potato residues, 200-300 parts of chicken manure, 60-80 parts of ammonium sulfate, 30-50 parts of magnesium sulfate, 50-60 parts of potassium sulfate, 15-20 parts of zinc sulfate, 10-15 parts of borax, 80-100 parts of achnatherum inebrians, 60-80 parts of anabasis, 80-90 parts of radix aconiti kusnezoffii, 60-90 parts of sophora alopecuroids and 8-10 parts of soil conditioner. The soil conditioner contains a jade component with a great number of trace elements beneficial to human bodies, and meanwhile, the soil conditioner contains an adsorption component capable of effectively adsorbing and curing toxic heavy metal elements in soil and increasing the yield of crops. According to the invention, the two wastes which are hardest to treat are combined and utilized artfully and are turned into things of value, the environment pollution problem is solved, meanwhile, nutrients and trace elements are provided for plants, and the nutritive value is very high.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a sweet potato dregs chicken manure fertilizer and a preparation method thereof. Background technique [0002] As one of the main raw materials of starch production plants, sweet potato consumes a lot. In the process of utilizing sweet potatoes to produce starch, in order to ensure the quality and color of starch, sweet potato dregs must be removed. It is very difficult to deal with a large amount of sweet potato dregs produced by starch factories. One of the existing treatment methods is to directly bury it, which not only occupies the field, but also rots and smells, polluting the environment. Another treatment method is to clean it and use it as a feed raw material, but as a feed raw material, not only the nutritional content does not meet the standard, but also the processing cost is relatively high. [0003] As we all know, because the chicken manure is dir...
