Abstract

The invention discloses a special slow-release fertilizer for resisting diseases and improving the quality and yield of rapeseeds. The special slow-release fertilizer is prepared from the following raw materials: urea, molasses powder, monoammonium phosphate, potassium chloride, EDTA chelated zinc, EDTA chelated manganese, EDTA chelated copper, borax, amino acid, Fe3O4/chitosan magnetic microspheres, tung oil and a starch/silica sol/nano-TiO2 compound. The invention also discloses a preparation method of the special slow-release fertilizer for resisting diseases and improving the quality and yield of rapeseeds. The special slow-release fertilizer for oilseed rape can avoid premature senility and fertilizer loss, ensures nutrient absorption during flowering and seed setting of the oilseed rape, and improves the quality and yield of the oilseed rape.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special slow-release fertilizer that resists diseases and improves the quality and yield of rapeseed and its preparation method. Background technique [0002] Rapeseed is an oil crop with strong adaptability, wide application, high economic value and great development potential. Rapeseed often needs to continuously absorb various nutrients needed for growth during the period of flowering and setting seeds, but the existing fertilizers usually cannot achieve the effect of sustained slow release and the nutrient utilization rate of fertilizers is low, which limits the sustainable development of rapeseed during the period of flowering and setting seeds. Strong growth. The Jingmen area of ​​Hubei is one of the important production areas of rapeseed in the country, and it is very suitable for research and development experiments on slow-release fertilizers for rapeseed. The de...
