Obtaining and Studying In Situ a Chitosan–Titanium Dioxide Composite Material for Agriculture
摘要
Granules of a chitosan–titanium dioxide composite material with different concentrations of titanium dioxide nanoparticles for agricultural use are obtained. The average diameter of the granules is 35 mm. It is shown that varying the concentration of titanium dioxide nanoparticles in the composite material within the studied limits does not affect the structure of its surface. Experiments are carried out in situ on the seeds of cucumber (Cucumis sativus). It is noted that, during the first three weeks, the composite material has an inhibitory effect on plant growth, and then, after the onset of dissolution of the granules, it has a growth-stimulating effect. The best growth rates are observed when two granules of a composite material with a ratio of chitosan to titanium dioxide of 3 to 1 are added to the soil. It is concluded that the obtained granules of a chitosan–titanium dioxide composite material can have a positive effect on the processes of plant growth and formation.
