磷尾矿基调理剂对樱桃萝卜萌发、生长及氟积累的影响
Effects of Phosphate Tailings-based Conditioner on Germination,Growth and Fluorine Accumulation of Cherry Radish
摘要
Abstract
To evaluate the effects of phosphate tailings-based conditioner(PTC)on the growth of radish crops and its flu-orine release risk during soil improvement,this study conducted seed germination and pot experiments to examine germina-tion,growth and fluorine accumulation and transformation in cherry radish(Raphanus sativus).Radicus persicatus culti-vated in soils amended with 0%(CK),0.05%,0.50%,2.00%and 5.00%PTC.The results showed that the germina-tion energy,germination rate and germination index of cherry radish seeds were not inhibited in soil with PTC content≤5%.Moreover,such PTC levels promoted the expansion of fleshy roots and the increase in plant height of cherry radish at maturity.While PTC addition elevated pre-planting soil levels of total fluorine,bioavailable fluorine,total calcium and water-soluble calcium,these values for bioavailable fluorine and water-soluble calcium declined at maturity,suggesting their uptake by radish or immobilization in the soil.The accumulation of fluorine in underground roots increased with the amount of PTC in the soil,whereas the accumulation in shoots exhibited an inverse trend.A significant reduction in the root-to-shoot transfer factors of fluorine indicated that PTC restricted fluorine translocation from roots to shoots.This phe-nomenon likely stems from the uptake of calcium by cherry radish roots and the calcium-fluorine co-precipitation mecha-nism,which concurrently reduced fluorine's interference with aerial physiological processes(e.g.,photosynthesis),pre-venting fluorine toxicity in cherry radish when soil PTC≤5%.These findings provide a theoretical foundation for optimi-zing PTC application strategies and managing fluorine risks.关键词
