Abstract

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.

壳聚糖-二氧化钛农业复合材料的原位获取与研究

摘要获得了含有不同浓度纳米二氧化钛的壳聚糖-二氧化钛复合材料农用颗粒。颗粒的平均直径为 35 毫米。实验表明，在研究范围内改变复合材料中二氧化钛纳米粒子的浓度不会影响其表面结构。对黄瓜（Cucumis sativus）种子进行了现场实验。实验结果表明，在最初的三周内，复合材料对植物的生长有抑制作用，而在颗粒开始溶解后，复合材料对植物的生长有促进作用。在土壤中加入两种壳聚糖和二氧化钛比例为 3:1 的复合材料颗粒时，植物的生长率最高。由此得出结论，壳聚糖-二氧化钛复合材料颗粒对植物的生长和形成过程有积极作用。

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
