Abstract
Potted experiments were conducted in a solar-heated greenhouse to investigate the effects of treflan applied into irrigation water on root distribution of subsurface drip irrigated tomatoes and clogging.The experiment includes one controlled sample without treflan and two samples with treatments sharing the same treflan application level but applied at different times.For treatment A the treflan was applied on the 3~(rd) day after transplantation,whereas for treatment B the treflan was applied on the 24~(th) day.The Tomato roots were sampled at harvest and analyzed by using the software WinRHIZO.The results show that,as far as the root length density around the drippers in concerned,both samples with treatment are significantly lower than the sample without treflan,which means application of treflan into irrigation water can reduce the potential of dripper's root clogging.The total root length,surface area,dry weight and volume for sample with treatment A are approximately the same as that without treflan,whereas these parameters of sample with treatment B is significantly lower than the controlled one.There are no differences in tomato biomass accumulation above the ground among these samples.No treflan residues were found in tomato fruits.
