英文摘要	Afforestation plays a crucial role in environmental management for many countries. Yet, frequently extreme high temperature (EHT) events in arid and semi -arid regions easily cause the death of artificially planted saplings. To address this, we present a new in -situ supplementary irrigation device (SID) consisting of a rainwater catching board, a storage tank, and ceramic emitters. A continuous EHT experiment combined with the HYDRUS-2D model in North China is further conducted to investigate the soil water -heat properties of the in -situ SID and the growth performance of the planted saplings ( Platycladus orientalis ) under EHT. The results show that in -situ SID keeps a stable and suitable soil water -heat status in the root layer of the planted saplings under EHT. Especially, the in -situ SID with one ceramic emitter maintains the soil water moisture in a narrow and suitable range from 0.149 cm 3 cm -3 to 0.153 cm 3 cm - 3 , and reduces the maximum soil temperature by 2.7 degrees C compared to the traditional irrigation method. Furthermore, the in -situ SID with one ceramic emitter presents the highest average leaf water content (66.9%), new shoot (35.0 mm), and tree height (62.0 mm). The economic benefit analysis finds that the in -situ SID provides a shorter time to recover high funds and saves a large amount of irrigation water resources. Overall, this study provides an effective irrigation device for forest managers to improve the ecological service effectiveness of afforestation in areas with frequent EHT events and scarce water resources.
