Abstract: The influence of corn straw,SEM bio-bacterial fertilizer, soil conditioner and their combination on the growth, fruit setting and fruit quality of over-winter tomato in solar greenhouse was studied using a field experiment. The result showed that all treatments had no obvious effect on growth, and positively increased the fruit rate of tomato. The fruit rate of the first to fourth cluster in ‘straw+EM +conditioner’ treatment was significantly increased, up to 24.07%, 24.07%, 16.86% and 24.07% respectively. The net photosynthetic rate, stomatal conductance, transpiration rate and intercellular CO2 concentration in all treatments were also improved, and the effect of ‘straw+EM+conditioner’ treatment was most significant, the maximum net photosynthetic rate 15.64% higher than control. In addition, all treatments appeared fruit soluble solids, total acid (titratable acid), Vc, soluble sugar and soluble protein contents increased. The soluble solids, total acid and soluble protein contents in the ‘straw+EM+conditioner’ treatment was significantly increased. In summary, straw, bio-bacterial fertilizer and soil conditioner can be used in greenhouse tomato production.
