摘要

使缓释和控释氮肥(SCRNFs)的氮(N)供应量与水稻的氮需求量同步,对于用缓释和控释氮肥的单次基施取代多次施用尿素至关重要。传统的氮供应特性评估主要侧重于氮释放模式,而这种模式只适用于涂层型 SCRNF,忽略了氮的转化机制,因此需要一种更通用、更可靠的指标。根据作物氮状况检测氮缺乏或过量的能力,我们假设采用叶片氮平衡指数(NBI)作为氮状况的衡量指标,可以为评估 SCRNF 的氮供应特性提供新的见解。我们进行了田间试验,涉及四种单独的 SCRNF--腐植酸尿素(HAU)、硫包尿素(SCU)、脲酶抑制剂尿素(UIU)和聚合物包膜尿素(PCU)--及其四种组合形式,以及作为对照的高产尿素分施(CK)。结果表明,NBI 相对于 CK 的动态变化可以反映不同 SCRNF 的氮供应潜力,同时将它们分为短效、中效和长效肥料。添加长效 SCRNF(PCU)的组合在产量(5.5%)和氮利用效率(42.8%)方面始终优于其他组合,因为它们在整个水稻生长周期中提供了更稳定、更高效的氮供应。谷物产量与 SCRNFs 和 CK 的 NBI 动态差异呈负相关,表明一次性施用 SCRNFs 和常规高产施肥之间的同步氮供应是实现高产的关键。我们的研究结果确定了通过叶片 NBI 诊断氮状况来评估 SCRNFs 氮供应特性的潜力,并强调了同步氮供应对一次性施用 SCRNF 的重要作用。

Optimizing rice yield: evaluating the nitrogen supply characteristics of slow- and controlled-release fertilizers using the leaf nitrogen balance index
Synchronizing the nitrogen (N) supply of slow- and controlled-release N fertilizers (SCRNFs) with rice N demand is pivotal in substituting multiple urea applications by a single basal application of SCRNFs. Traditional assessment of N supply characteristics focuses mainly on N release patterns, which are only applicable to coated SCRNFs and ignore N transformation mechanisms, thus raising the need for a more universal and reliable index. Based on the ability of crop N status to detect N deficiency or excess, we hypothesized that employing leaf N balance index (NBI) as a measure of N status could provide new insights into assessing N supply characteristics of SCRNFs. We conducted field experiments involving four individual SCRNFs-humic acid urea (HAU), sulfur-coated urea (SCU), urease inhibitor urea (UIU), and polymer-coated urea (PCU)- and their four combined forms, along with the high-yield urea split application as control (CK). The results showed that NBI dynamics relative to CK could reflect the N supply potential of different SCRNFs while classifying them as short-, medium-, and long-acting fertilizers. Combinations that incorporated the long-acting SCRNF (PCU) consistently outperformed others in yield (by 5.5%) and N use efficiency (by 42.8%) by providing a more consistent and efficient N supply throughout the rice growth cycle. Grain yield showed negative correlation with the difference in NBI dynamics between SCRNFs and CK, indicating synchronizing N supply between one-time application of SCRNFs and conventional high-yield fertilization is the key for high yield. Our findings identify the potential of N status diagnosed by leaf NBI to evaluate N supply characteristics of SCRNFs and emphasize the significant role of synchronized N supply for a one-time SCRNF application.
