Abstract:
Tomato was used as test material，the effects of low pressure oistube-irrigation on greenhouse microclimate and field tomato growth characteristics were studied.To explore the suitability of low pressure oistube-irrigation of facilities greenhouse.The results showed that the change of oistube-irrigation ground temperature was more stable than that of dripirrigation;the ground temperature of tomato seedling-fruit stage was 2.98 ℃ higher than that of dripirrigation and 2.03 ℃ lower than that of dripirrigation in fruit-mature period.Oistube-irrigation had a positive effect on regulating the solar greenhouse microclimate，increasing indoor temperature by 2.63 ℃ and humidity by 11.2 percentage point compared with dripirrigation，respectively.The root diameter and stem diameter of oistube-irrigation were 19.30% and 14.50% higher than that observed in dripirrigation.However，the main root length and quantity of dripirrigation increased by 13.80% and 11.29%.Oistube-irrigation increased tomato growth trend especially at the stage of seedling-fruit.Oistube-irrigation increased the diameter of the stem and quantity of fibrous root of tomato，but it inhibited the length and quantity of main root.
