Abstract

Aim

This multidisciplinary study explores the effects of hydrogel mixed with sawdust and soil on the sorption properties and vitality of poplar cuttings under drought conditions.

Results

The hydrogel–sawdust mixture exhibited superior water retention, absorbing up to 1.11 g water per gram of dry mixture, significantly improving soil moisture compared to soil alone. Fertilizer addition to the hydrogel enhanced nutrient availability without substantially affecting soil pH. Notably, the combination of sawdust and hydrogel balances nutrient availability while maintaining moisture levels, supporting plant growth during drought. Physiological analyses indicate that these mixtures positively affect plant vitality, as evidenced by increased photosynthetic performance. Chemical composition of plants remained largely stable, with minor changes in the proportion of cellulose and hemicelluloses.

Conclusion

This study uniquely combines scanning electron microscopy (SEM) analysis, and comprehensive chemical and physiological analyses to highlight the benefits of hydrogel in forest management, particularly under water stress conditions.

通过水凝胶和木屑组合优化土壤特性，促进植物生长

目的研究干旱条件下木屑与土壤混合水凝胶对杨树扦插枝吸附特性和活力的影响。结果水凝胶-木屑混合物具有较好的保水性，每克干燥混合物吸水率高达1.11 g，与单独使用土壤相比，显著提高了土壤水分。向水凝胶中添加肥料可以提高养分有效性，但不会对土壤ph产生实质性影响。值得注意的是，木屑和水凝胶的组合可以平衡养分有效性，同时保持水分水平，在干旱期间支持植物生长。生理分析表明，这些混合物对植物活力有积极影响，如提高光合性能所证明的那样。植物的化学成分基本保持稳定，纤维素和半纤维素的比例略有变化。本研究独特地将扫描电镜（SEM）分析与综合化学和生理分析相结合，突出了水凝胶在森林管理中的益处，特别是在水分胁迫条件下。

期刊介绍： Established in 1922, the Journal of Plant Nutrition and Soil Science (JPNSS) is an international peer-reviewed journal devoted to cover the entire spectrum of plant nutrition and soil science from different scale units, e.g. agroecosystem to natural systems. With its wide scope and focus on soil-plant interactions, JPNSS is one of the leading journals on this topic. Articles in JPNSS include reviews, high-standard original papers, and short communications and represent challenging research of international significance. The Journal of Plant Nutrition and Soil Science is one of the world’s oldest journals. You can trust in a peer-reviewed journal that has been established in the plant and soil science community for almost 100 years. Journal of Plant Nutrition and Soil Science (ISSN 1436-8730) is published in six volumes per year, by the German Societies of Plant Nutrition (DGP) and Soil Science (DBG). Furthermore, the Journal of Plant Nutrition and Soil Science (JPNSS) is a Cooperating Journal of the International Union of Soil Science (IUSS). The journal is produced by Wiley-VCH. Topical Divisions of the Journal of Plant Nutrition and Soil Science that are receiving increasing attention are: JPNSS – Topical Divisions Special timely focus in interdisciplinarity: - sustainability & critical zone science. Soil-Plant Interactions: - rhizosphere science & soil ecology - pollutant cycling & plant-soil protection - land use & climate change. Soil Science: - soil chemistry & soil physics - soil biology & biogeochemistry - soil genesis & mineralogy. Plant Nutrition: - plant nutritional physiology - nutrient dynamics & soil fertility - ecophysiological aspects of plant nutrition.
