Other claims from this paper (9)
- Intervention effect Drip irrigation and fertilization significantly improved water productivity and fertilizer agronomic use efficiency of grape compared with the CK and CG treatments.
- Observation The highest grape yields were obtained with the F2 treatment under drip fertigation.
- Observation The highest grape yield in wet years was 16044 kg/hm2, obtained at W1F2.
- Observation The highest grape yield in dry years was 12728 kg/hm2, obtained at W2F2.
- Intervention effect Under W1 irrigation at the same F2 fertilization level, grape yield was 37.95% higher in wet years than in dry years.
- Intervention effect Under W2 irrigation at the same F2 fertilization level, grape yield was 23.73% higher in wet years than in dry years.
- Intervention effect Under W3 irrigation at the same F2 fertilization level, grape yield was 23.50% higher in wet years than in dry years.
- Recommendation For wet years, the response-surface optimal irrigation and fertilization intervals were given, with irrigation of 8 to 11 mm.
- Recommendation For dry years, the response-surface optimal irrigation and fertilization intervals were given, with irrigation of 32–38 mm.
