Non-ventilation irrigation used as control group,two different kinds of ventilation volume(50% of soil porosity as a reference standard,ventilation coefficients were set 0.8,1.2) and with three different soil moisture(60%～70%,70%～80%,80%～90%of field capacity) were set.The growth of tomato plants under ventilation irrigation treatment was significantly promoted.In addition to T2 treatment(ventilation coefficient is 1.2,60%～70% of field capacity),yields of the remaining ventilation irrigation were higher(20%)...
