- Observation Leaf blade nitrogen content exceeded leafstalk nitrogen content.
- Observation Leaf nitrogen content declined during vine growth.
- Intervention effect Fertilization at 20 to 40 cm significantly increased leaf nitrogen content.
- Observation Leafstalk nitrogen was less affected by fertilization depth and season.
- Observation Leafstalk phosphorus exceeded leaf blade phosphorus.
- Observation Leaf phosphorus changed little during vine growth.
- Intervention effect Fertilization at 40 to 60 cm significantly promoted phosphorus in leaf blade and leafstalk.
