Efficient slow release fertilizer used for wheat and having function of resisting dry and hot wind

Abstract

The invention discloses an efficient slow release fertilizer used for wheat and having the function of resisting dry and hot wind. The slow release fertilizer is prepared from raw materials in parts by weight as follows: 25-45 parts of fermented chicken manure, 10-15 parts of seabird faeces, 6-14 parts of bone residues, 10-20 parts of fermented peanut meal, 10-20 parts of pond silt, 3-7 parts of biochemical fulvic acid powder, 3-5 parts of sodium nitrophenolate, 4-10 parts of water-soluble boron, 3-7 parts of carbasalate calcium, 25-45 parts of potassium sulfate, 30-40 parts of ammonium bicarbonate, 35-55 parts of modified urea, 4-10 parts of montmorillonite, 4-8 parts of turf, 3-7 parts of sepiolite powder, 4-8 parts of bentonite, 0.3-0.7 parts of EDTA chelating iron, 1.5-2.5 parts of clay, 0.4-1 part of EDTA chelating manganese and 0.03-0.06 parts of compound bacteria. The slow release fertilizer meets the demand law of the wheat for nutrients, can stabilize the biological membrane structure and improve the cell activity and is stable in dry and hot wind resistance.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer for high-efficiency wheat resistant to dry and hot wind. Background technique [0002] The wheat planting area in Huanghuaihai area of ​​my country accounts for 68% of the total wheat area in the country, ranking first in the country. This wheat area is not only the main producing area of ​​winter wheat in my country, but also the most severely damaged area by dry hot wind. After the wheat is damaged by the dry hot wind, the parts of the wheat lose water and become dry, the glumes are gray and dull, the awn tips are dry, the wheat awns are opened, the leaves are curled and withered, the stems are withered and white, and the severe ones are burnt and fried. Dark and dull. Plant transpiration intensity increases, plant water content decreases, and water metabolism is out of balance; photosynthetic rate decreases, grains become dry, and thousand-grain weigh...

AI Technical Summary

Problems solved by technology

Seriously affect the yield and quality of wheat

At present, there is a lack of wheat dry and hot air fertilizer that is rich in nutrients, has good fertilizer efficiency, and is stable against dry hot air, and is easy to use.
