    摘要:

    糖醇是许多植物的光合作用初产物,在植物体内具有多种生物学效应,作为配体合成的糖醇螯合肥能促进钙、硼等营养元素在植株韧皮部迁移,该特性使其在农业生产中备受关注,但是糖醇螯合肥在我国的发展仍处于初始阶段,其科学研究远滞后于实际应用,根源在于当前的研究侧重糖醇螯合肥的作物效应,较少关注施用糖醇螯合肥对土壤环境及根际、叶际微生物造成的生态影响。同时,既往的研究通常忽略糖醇配体在生物体内的作用,且应用的糖醇螯合肥多为混合物,难以明确是糖醇、糖醇螯合物或按一定比例合成的混合物对作物生长起到关键作用。此外,由于糖醇螯合物的螯合机理不明,难以利用有效手段对其进行定性与定量分析,也阻碍了糖醇螯合肥的肥效机理研究。基于此,本文简要阐述了糖醇螯合技术及糖醇螯合肥的优势,并概述了糖醇配体在植物体内的生物学效应,通过当前糖醇螯合肥的应用现状指出糖醇螯合肥应用研究和开发中的不足,旨在为糖醇螯合肥的发展提供技术依据与发展方向。

    Abstract:

    Sugar alcohols which are products of photosynthesis of many plant species have a variety of biological effects and participate in plant life activities through different ways. Sugar alcohols-chelated fertilizers synthesized with sugar alcohol as a chelating ligand promote the migration of calcium, boron, and other nutrients in plants. Although related studies have shown that sugar alcohol chelating agent can effectively improve crop yield and quality, its development in China is still in the initial stage. One reason for this slow adoption is that researchers pay more attention to the efficiency of sugar alcohol chelated fertilizers than they do for the response mechanism of crops under different conditions. Thus, scientific research on sugar alcohol chelated fertilizers lags far behind its practical application, which has resulted in the lack of in-depth understanding of the ecological effects. Importantly, previous studies have often neglected the role of sugar alcohols in organisms, and sugar alcohol chelated fertilizers are mostly mixtures, so it was difficult to distinguish whether sugar alcohols or sugar alcohol complexes played a key role in promoting crop growth. Besides, due to the unclear chelating mechanism of sugar alcohol complexes, it was difficult to use available methods to perform qualitative and quantitative analysis. This hindered the promotion and application of sugar alcohol chelated fertilizers in China's agriculture. Based on the above reasons, this paper briefly describes (i) sugar alcohol chelating technology, (ii) the advantages of sugar alcohol chelated fertilizers, (iii) the biological effects of sugar alcohols in plants, and (iv) the shortcomings in the research of sugar alcohol chelated fertilizers through the current application status. Thus, this review aims to provide a technical basis and development direction for the research, development, and popularization of sugar alcohol chelated fertilizers.
