Other claims from this paper (11)
- Intervention effect Leaf glutamine synthetase activity and soluble protein content first increased and then decreased with increasing nitrogen application.
- Intervention effect Potassium application significantly increased leaf glutamine synthetase activity and soluble protein content.
- Observation Leaf nitrogen metabolic capacity was greatest at the K1N2 fertilizer ratio.
- Intervention effect Leaf SPAD increased with increasing nitrogen application.
- Intervention effect Net photosynthetic rate, stomatal conductance and intercellular CO2 first increased and then decreased as nitrogen application rose.
- Intervention effect Potassium fertilizer significantly affected net photosynthetic rate, stomatal conductance and intercellular CO2 concentration.
- Intervention effect Tuber starch and protein content increased as nitrogen application increased.
- Intervention effect Tuber soluble sugar content decreased as nitrogen application increased.
- Intervention effect Sweet potato vine length increased continuously with increasing nitrogen application.
- Intervention effect Potassium fertilizer significantly increased tuber number and stem thickness.
- Recommendation The authors conclude that an appropriate combined nitrogen–potassium application promotes nitrogen metabolism, photosynthesis, yield and quality.
