Actual water use efficiency的用法和样例：
- Raised bed planting (RBP) can get higher grain yield and water use efficiency than flat planting (FP).
- Relationship between soil water content and water use efficiency of apple leaves.
- The results showed that when SWC was 50.6%,the water use efficiency(WUE) was the highest.
- Rainfall interception by the canopy of turfgrass (Zoysia sinica Hance) has important effect on water use efficiency.
- The results showed that the water use efficiency was improved obviously by alternate-furrow irrigation.
