按照Nature期刊格式翻译下面一句话：通过引言部分的讨论和文献综述我们总结了研究差：热应力的发生与灌浆期高度重合导致灌浆中断严重限制了产量。然而通过补水缓解玉米高温的田间观测证据受到的关注有限。此外在特定的生长阶段如生殖阶段通过补水来缓解玉米的热效应还不清楚。

Through the discussion in the Introduction and literature review, we have summarized the research gap: the occurrence of heat stress coincides with the tasseling period, leading to interrupted pollination and severely limiting yield. However, there is limited attention to field observations of alleviating high temperatures in maize through irrigation. Additionally, it is unclear whether alleviating heat stress through irrigation is effective during specific growth stages, such as the reproductive stage
