Problems solved by technology

The thin film deposition method mainly uses vapor phase evaporation, spray pyrolysis method, pulsed laser deposition method, etc. These methods are not easy to control the size of ITO nanoparticles
Solution-based synthesis includes Penchini method, co-precipitation method, etc., many methods can only get In(OH) 3 Or InOOH precursor, further heating is required to obtain oxide products, and the use of surfactants will also cause its residue on the ITO material, affecting the subsequent characterization and use of the material

Abstract

The invention discloses a method for promoting cut-flower Chinese roses to absorb light by using ITO nano particle sol as leaf fertilizer. The method includes the steps that 1, ITO nano particles aresynthesized; 2, ITO leaf fertilizer is synthesized; 3, the method for applying the ITO leaf fertilizer is implemented. The synthesized ITO nano particle sol is used as the leaf fertilizer for the first time, in this way, the photosynthesis of the cut-flower Chinese roses is enhanced, the range of absorption wavelength in photosynthesis of plant leaves is enlarged, and potential application is broad in photosynthesis absorption of plants.

Description

technical field [0001] The invention belongs to the technical field of nanotechnology and new materials, and in particular relates to a method of using ITO nanoparticle sol as a foliar fertilizer to promote the light absorption of cut flower roses. Background technique [0002] In recent years, with the development of fertilization technology, foliar fertilization has been rapidly promoted and applied as a fertilization measure to strengthen the nutrient absorption of garden plants and prevent certain deficiency symptoms. Practice has proved that foliar fertilization is one of the fertilization techniques with rapid fertilizer efficiency, high fertilizer utilization rate and low dosage. Traditional fertilizers provide nutrients to the roots of plants, while foliar fertilizers provide energy to plant leaves. Relevant studies have shown that foliar fertilizers are more effective than traditional fertilizers. [0003] Compared with traditional fertilizers, foliar fertilizers h...
