Other claims from this paper (11)
- Intervention effect Intelligent drip fertigation reduced irrigation water application rate by 33% in watermelon.
- Intervention effect Intelligent drip fertigation reduced N application rate by 46% in watermelon.
- Intervention effect Intelligent drip fertigation reduced P2O5 application rate by 72% in watermelon.
- Intervention effect Intelligent drip fertigation reduced K2O application rate by 57% in watermelon.
- Intervention effect Intelligent drip fertigation did not compromise watermelon yield and fruit quality.
- Observation Dry matter accumulation and N, P2O5 and K2O uptake of watermelon were fitted well by a logistic growth function.
- Observation Dry matter accumulation during the fruit expanding stage to whole growth stage was 79.0% of the total in greenhouse watermelon.
- Observation N uptake during the fruit expanding stage to whole growth stage was 67.9% of the total in greenhouse watermelon.
- Observation P2O5 uptake during the fruit expanding stage to whole growth stage was 72.4% of the total in greenhouse watermelon.
- Observation K2O uptake during the fruit expanding stage to whole growth stage was 71.8% of the total in greenhouse watermelon.
- Mechanism Intelligent drip fertigation may improve watermelon root uptake and translocation capacity for water and nutrients.
