在酸性土壤上使用活性磷矿石(RP)作为牧草和大田作物的磷源相对于可溶性磷酸盐而言具有明显的经济优势。然而,一些研究表明活性RP的短期效应(1年)比水溶性磷差,表现为不但对早期收获的作物产量和品质不利,而且对总产量也不利,特别是当作物在施用初期受到生物或非生物胁迫的影响时。本研究中,我们对利用新型土壤生物刺激素提高酸性土壤上应用RP肥料作为牧 The use of activated phosphate rock (RP) on acid soils as a source of phosphorus for pasture and field crops has significant economic advantages over soluble phosphates. However, some studies indicate that the short-term effect (1 year) of active RP is poorer than that of water-soluble phosphorus, not only for yield and quality of early-harvested crops but also for total yield, especially when the crop is exposed to biological or The impact of abiotic stress. In this study, we investigated the application of new soil bio-stimulants to improve the application of RP fertilizers on acidic soils
