Abstract:
A randomised group trial was conducted with ‘Kenpan 1503’.The experiment was conducted to study the effects of different irrigation rates and water terminating times on the ripening and yield of processed tomatoes under drip irrigation conditions,in order to provide a reference basis for field management of processed tomatoes.The results demonstrated that different irrigation rates and water terminating times had significant effects on fruit weight,fruit maturity and yield traits (yield,red fruit rate,green fruit rate and rotten fruit rate).This included significant effects on quality traits (fruit soluble solid content,lycopene,β-carotene and chlorophyll content).The optimum harvest time for processing tomatoes was 14 d after water stoppage,with an optimum irrigation rate of 4 875 m3·hm-2,resulting in a yield of 18.25×104 kg·hm-2 and 95.24% fruit ripeness.Green and rotten fruit rates were low,fruit soluble solid content reached 5.43% and lycopene content reached 20.97 mg·（100g）-1.
