Abstract:
To determine the appropriate irrigation amount of tomato in Xinjiang greenhouse，the field experiment was conducted to study the impact of different irrigation treatments on tomato growth，photosynthetic characteristics and yield in the research base of Xinjiang Academy of Agricultural and Reclamation Science.The results showed that plant height and stem diameter under every treatment increased fast at the seedling stage，with the propulsion of growth stage，tomato went into the vegetative and reproductive growth stage at the same time，in order that plant height and stem diameter grew slower until stably.Plant height and stem diameter increased with the amount of irrigation on the whole，which of T4 was the highest，T3 followed，and T1 was the lowest；net photosynthetic rate (Pn) and stomatal conductance (Gs) at each growth stage of tomato overall increased as the irrigation amount growing，the diurnal variation of net photosynthetic (Pn) rate at seedling stage was a single peak curve with the peaking at 13:00，which of flowering and maturity picking stage were bimodal curve，and the peaks appeared at 11:00 and 15:00.Stomatal conductance (Gs) curve at each growth stage was bimodal peak which appeared at 11:00 and 15:00.The size order of yield under four irrigation amount was T3>T4>T2>T1.Comprehensive analysis of the test results，the net photosynthetic (Pn) rate and stomatal conductance (Gs) of tomato under T3 had no significant difference with T4，and the yield was the highest，which indicated that the irrigation amount of 320 m3/667m2 was more appropriate to tomato in greenhouse of Xinjiang.
