Oxygen aeration coated fertilizer with high enzymatic activity

Abstract

The invention discloses an oxygen aeration coated fertilizer with high enzymatic activity. The oxygen aeration coated fertilizer is prepared from the following materials in parts by weight: 2-3 parts of a peptidase preparation, 1-2 parts of enzyme, 36-38 parts of vinasse, 30-33 parts of biogas residue, 2-3 parts of sodium tartrate, 4-5 parts of calcium chloride, 5-6 parts of monoammonium phosphate, 4-6 parts of potassium feldspar powder, 12-14 parts of urea, 16-19 parts of a 30% hydrogen dioxide solution, 2-3 parts of laxogenin powder, 0.8-1.0 part of butyl acrylate, 2-3 parts of dry sodium dihydrogen phosphate powder, 1.2-1.5 parts of nano-zinc oxide and a proper amount of water. The enzyme preparation is pelletized, adsorbed and coated with an outer membrane, the scattered distribution of the enzyme in a soil layer in a free state is reduced, the activity of the enzyme is prevented from being affected by soil acidity alkalinity, the vitality of the enzyme in the fertilizer is effectively reduced, the release of a fertilizer nutrient is promoted, and the fertilizer efficiency of the fertilizer is further prolonged.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an oxygen-increasing coated fertilizer with high enzyme activity. Background technique [0002] With the abnormal global climate, heavy rains and floods occur frequently in some areas. At the same time, factors such as improper irrigation or poor drainage often cause waterlogging in crop land, making the soil in a state of flooding. Under flooding conditions, the gas in the soil is forced to discharge. It is easy to cause insufficient oxygen in the soil. Oxygen is necessary for plant root respiration. Long-term hypoxia will hinder the electron transfer of plant cells, accumulate a large amount of active oxygen, damage the structure and function of cell membranes, and even cause a large number of crops to die. Under hypoxic stress, the root system accumulates a large amount of toxic substances such as ethanol and lactic acid, the root metabolism is disordered, and the aerobic...

AI Technical Summary

Problems solved by technology

The invention has higher fertilizer nutrient content and faster fertilizer efficiency, but it does not effectively increase the oxygen content of the soil plow layer, and it cannot improve the resistance of crops against unfavorable conditions such as flooding, and there is no significant increase in added value, which limits the use of fertilizers. use
