Abstract

The invention belongs to the field of agriculture and particularly discloses efficient trace element liquid fertilizer and a preparation method thereof. The efficient trace element liquid fertilizer is prepared on the basis of fermentation of livestock manure with high water content, a trace element solution and a composite additive are added to the livestock manure, the mixture is chelated and concentrated, and the efficient trace element liquid fertilizer is prepared. The content of the trace elements in the prepared efficient trace element liquid fertilizer is not lower than 100 g/L. Therefore, the efficient trace element liquid fertilizer has the advantages of high nutrition facts, balanced ratio, high stability, convenience in application and the like, effectively solves the problem that the livestock manure in rural areas is difficult to use due to overhigh water content at present and has broad application prospects.

Description

technical field [0001] The invention specifically relates to the preparation of high-efficiency trace element liquid fertilizer by fermenting livestock and poultry manure with high moisture content and a method thereof, which belongs to the technical field of agricultural organic waste recycling and also belongs to the field of liquid fertilizer in the agricultural field. Background technique [0002] Under the background of my country's implementation of new rural construction, the recycling of organic waste in rural areas has become a top priority. At present, the massive discharge of livestock and poultry manure in rural areas and the irregular burning of crop residues have led to increasingly serious pollution of the rural ecological environment. It is estimated that by 2020, the total discharge of livestock and poultry manure in my country will reach 4.5 billion tons, of which the discharge of free-range farming in rural areas will account for at least half. Since most...
