- Intervention effect Micro-drip irrigation lowered nitrogen concentration near cucumber roots by more than 24% relative to subsurface drip irrigation.
- Intervention effect Micro-drip irrigation raised soil urease activity by 31.5%.
- Intervention effect Micro-drip irrigation raised soil alkaline phosphatase activity by 37.7%.
- Intervention effect Micro-drip irrigation raised partial nitrogen productivity by 22.1%.
- Intervention effect High fertilization raised cucumber yield by 20%–45% versus low and medium fertilization.
- Intervention effect High fertilization lowered soil urease activity by 11.4%–15.3%.
- Intervention effect High fertilization lowered soil alkaline phosphatase activity by 11.5%–23.0%.
- Intervention effect High fertilization significantly raised nitrogen concentration around cucumber roots.
- Recommendation The authors identified 300 kg N hm-2 under micro-drip irrigation as the optimal fertilization level for greenhouse cucumber.
