Summer crops are exposed to heat and drought stresses at critical stages during and after flowering, and their intensity and frequency are likely to increase with climate change. Agronomic stress avoidance offers the opportunity to temporally separate critical crop stages from heat and drought events. However, it might require sowing cold-sensitive summer crops earlier into colder than recommended soil temperatures. There is a need to understand how cold is too cold to sow summer crops early in late winter as well as what are the yield benefits and risks.

对热应激的农艺适应：提前播种夏季作物


夏季作物在开花期间和开花后的关键阶段会受到高温和干旱胁迫，其强度和频率可能会随着气候变化而增加。农艺胁迫避免提供了在时间上将关键作物阶段与高温和干旱事件区分开来的机会。但是，它可能需要将对寒冷敏感的夏季作物早播种到比推荐土壤温度更冷的土壤温度下。有必要了解在冬末早期播种夏季作物有多冷，以及产量、收益和风险是什么。
