植物磷素吸收机理研究进展
Research Progress on the Mechanism of Plant Phosphorus Absorption
磷是植物生长发育所必需的营养元素之一,对于植物的新陈代谢及蛋白质、脂肪、碳水化合物和维生素的合成、分解和转化有着重要作用,同时也是构成植物体内ATP、蛋白等大分子物质的重要组分。在农林业生产中,磷是决定土壤肥力和质量的关键指标,磷肥的施用对植物吸收磷的有效性至关重要。然而,磷肥的来源是一种磷酸盐矿石,属于不可再生资源。据世界磷矿储量估计,在未来 50～100 年内磷酸盐矿石将被耗尽,但是在我国许多农业土壤中仍存在过量施用磷肥的现象。磷素缺乏是限制…查看全部>>
Phosphorus is one of the essential nutrient elements for plant growth and development.It plays an important role in plant metabolism and the synthesis,decomposition and transformation of protein,fat,carbohydrates and vitamins.It is also a major component of ATP,nucleic acid,and protein in plants.An important component of molecular substances.In agricultural and forestry production,phosphorus is a key indicator that determines soil fertility and quality,and t…查看全部>>
