Other claims from this paper (12)
- Intervention effect Plastic-film drip irrigation gave the highest maize yield, WUE and NUE.
- Intervention effect Biodegradable-film drip irrigation gave the highest maize yield, WUE and NUE.
- Intervention effect Plastic-film irrigation consumed more soil water in two layers than biodegradable film.
- Intervention effect Plastic-film irrigation accelerated root and leaf senescence relative to biodegradable film.
- Intervention effect Straw-return drip irrigation promoted deeper root length density.
- Intervention effect Straw-return drip irrigation maintained higher physiological activity during reproduction.
- Intervention effect Furrow irrigation produced higher deep-layer nitrate than drip treatments.
- Intervention effect Furrow irrigation increased nitrogen leaching risk compared with drip treatments.
- Association Topsoil root length density was positively correlated with yield, WUE and NUE.
- Association Topsoil root length density was negatively correlated with root nitrogen use efficiency.
- Association The correlations of root length density with performance were weaker in deeper layers.
- Recommendation The authors recommend biodegradable-film drip irrigation for sustainable maize production in Northeast China.
