Water-retaining oxygen-increasing coated fertilizer

Abstract

The invention discloses a water-retaining oxygen-increasing coated fertilizer which is prepared from the following raw materials in parts by weight: 0.4-0.6 part of acrylamide, 1-2 parts of sodium hydrogen sulfite, 42-46 parts of cotton seed hull, 18-22 parts of chestnut shell powder, 3-4 parts of milk extract powder, 2-3 parts of potassium citrate, 1-2 parts of sodium silicate, 6-8 parts of turf powder, 10-12 parts of urea, 13-15 parts of 30% hydrogen peroxide solution, 1-2 parts of laxogenin powder, 0.4-0.6 part of butyl acrylate, 1-2 parts of dried sodium dihydrogen phosphate powder, 1.4-1.5 parts of nano-zinc oxide and a proper amount of water. According to the fertilizer disclosed by the invention, acrylamide and other raw materials with water retaining properties are added on the basis of nutrient ingredients, integration of the fertilizer and water-retaining agents can be realized, and the lowest moisture content available for a crop root system is guaranteed, so that the crops can maintain normal growth under waterflooding or drought conditions, the stress resistance of the crops is enhanced, and the yield and product quality of the crops in various adverse environments are effectively improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water-retaining and oxygen-increasing coated fertilizer. 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 respir...

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
