Abstract

The invention discloses a composite slow release fertilizer capable of improving the strawberry quality. The fertilizer is prepared from, by weight, 110-120 parts of macroelementfertilizer, 25-35 parts of sunflower seed meal, 4-12 parts of swelling soya dregs, 2-8 parts of alfalfa meal, 2-8 parts of turfy soil, 2-6 parts of coconut shell meal, 4-8 parts of soil improvement agent, 0.1-0.6 part of fulvic acid diamine iron and 0.4-0.9 part of zinc humate. The macroelementfertilizer is prepared from, by weight, 50-60 parts of composite urea, 25-35 parts of concentrated superphosphate, 10-18 partsof seabird excrement and 10-16 parts of cement kiln dust. The composite urea is prepared through the technology comprising the steps that bentonite and water are mixed, stirring is performed while thetemperature is increased, myristyltributyl ammonium chloride is added, stirring is performed while the temperature is increased, urea is added, paraffin is stirred, chitosan is added while stirring continues to be added, filtering is performed, a filter cake is washed, and drying and smashing are performed to obtain the composite urea.
