Abstract
[Objective] To investigate the effect of different soil irrigation on Qinghai Nuomuhong black fruit wolfberry photosynthetic characteristics and yield.[Method] We took the 3-year-old Qinghai Nuomuhong black fruit wolfberry newborn branches as test materials,and measured their leaf photosynthetic parameters and fruit yield by different levels of moisture control test.[Result] There were significant impact on black fruit wolfberry photosynthetic gas exchange parameters,with irrigation amount decreasing,black fruit wolfberry photosynthetic gas exchange parameters (photosynthetic rate,transpiration rate and stomatal conductance) showed first increasing then weakening trend;under different irrigation black fruit wolfberry chlorophyll content increased compared to the control,and there was significant differences among treatments;water use efficiency decreased gradually with irrigation amount increasing,and 3 000 m3/hm2 treatment was optimal for water use efficiency by 24.43 g/kg;4 500 m3/hm2 treatment was optimal for yield as 2 175 kg/hm2,but there was no significant difference between the 2 treatments.[Conclusion] According to the principles of sustainable economic use and soil moisture under different irrigation treatments under drip irrigation,irrigation quota of 3 000 m3/hm2 is better.关键词
