Multifunctional nano titanium dioxide composite foliar fertilizer

Abstract

The invention relates to multifunctional nano titanium dioxide composite foliar fertilizer, belonging to the technical field of fertilizer. The multifunctional nano titanium dioxide composite foliar fertilizer is prepared from the following components by mass percent: 5-15% of nano titanium dioxide, 40-50% of nitrogen phosphorus potassium fertilizer, 30-40% of micronutrient fertilizer, 0.5-1% of dispersant, 5-10% of complexing agent and 0.1-0.5% of surfactant, wherein the nitrogen phosphorus potassium fertilizer is prepared from the following components by mass percent: 40-50% of urea, 10-20%of ammonium chloride and 35-45% of dipotassium phosphate; the micronutrient fertilizer is prepared from the following components by mass percent: 30-40% of ferrous sulfate, 10-20% of zinc sulfate, 10-20% of copper sulfate, 15-25% of magnesium nitrate and 10-15% of calcium nitrate. The multifunctional nano titanium dioxide composite foliar fertilizer is prepared by utilizing the special photocatalytic function of the nano titanium dioxide and then compounding other foliar fertilizer components; the composite foliar fertilizer can promote the photosynthesis of green crops, can also promote the rapid absorption of other nutrient components by leaf surfaces, can also degrade the pesticide residue and other organic residues on the leaf surfaces, also has antibacterial, insect-resistant and leafsurface self-cleaning effects, and achieves the effects of strengthening seedlings, resisting diseases, sterilizing, increasing yield, improving quality, and the like.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a multifunctional nano-titanium dioxide composite foliar fertilizer, which can be widely used on the leaves of various green crops, and uses the special photocatalytic function of nano-titanium dioxide to compound other foliar fertilizer components. It can promote the growth of crops and achieve the effects of strong seedlings, disease resistance, sterilization, production increase, and quality improvement. Background technique [0002] Green crops absorb nutrients mainly through the root system and the leaves. As a direct and efficient auxiliary fertilization measure, foliar fertilizer has become an indispensable part of modern agricultural fertilizers. In foreign countries, the proportion of fertilizers applied by foliage has exceeded 40%, which shows the importance of foliar fertilization. The reason why foliar fertilizers are widely developed and applied is because foliar...
