Abstract

Agrogels, a hydrogel applied in the soil that collects water during irrigation or rainfall and distributes moisture to plant roots during drought, are a solution to water shortage concerns. Extending the release of low molecular weight chemicals has the potential to minimise mineral fertiliser losses as well as water and soil pollution. Thus, the aim of the research is to obtain chitosan from insect chitin, to synthesize a hydrogel based on chitosan with included mineral and organic fertilisers, and to report on experiments with agrogels in the field. In this study, chitosan was obtained from the adult beetles Zophobas morio. IR spectroscopy was used to examine chitosan. The existence of absorption lines typical of primary amines was demonstrated. In one step, a technique for the manufacture of chitosan-based hydrogels containing embedded mineral fertilisers was established. Hydrogel has a swelling coefficient of 60 g/g. Agrogels were evaluated while planting spruce seedlings on "Semei Ormany" LLP experimental locations. The survival rate of seedlings was found to be 40% higher in the experimental group than in the control group.

昆虫壳聚糖基水凝胶在松木种植中的应用。
水凝胶是一种应用于土壤中的水凝胶,在灌溉或降雨时收集水分,在干旱时将水分分配给植物根系,是解决水资源短缺问题的一种方法。延长低分子量化学品的释放有可能最大限度地减少矿物肥料的损失以及水和土壤污染。因此,本研究的目的是从昆虫甲壳素中提取壳聚糖,在壳聚糖的基础上合成含矿质和有机肥的水凝胶,并报道凝胶在田间的实验。本研究从成虫中提取壳聚糖。利用红外光谱对壳聚糖进行了表征。证实了伯胺的典型吸收谱线的存在。在第一步中,建立了一种以壳聚糖为基础的含有嵌入矿物肥料的水凝胶的制造技术。水凝胶的膨胀系数为60g /g。在“Semei Ormany”LLP实验地点种植云杉幼苗时,对凝胶进行了评价。结果表明,试验组幼苗成活率比对照组高40%。
