Abstract: Effects of different package fertilizers on tomato in facility were studied to provide references for high quality and high efficient production of tomato in Xi’an. Gibon package fertilizers (T1), Jingu package fertilizers (T2) and Yuanfeng compound fertilizers (T3, CK, namely the conventional fertilization) were used to set up three fertilization treatments. The results showed that: (1) as to soil organic matters, there was no obvious difference among the treatments after one season cultivation, however, compared with T3, T1 and T2 lowered the soil pH value and electrical conductivity; (2) the plant height, stem diameter, plant width and dry weight of stem and leaf of T3 were higher than those of T1 and T2, but tomato fruit weight, yield, soluble solid, vitamin C content and economic benefit of T3 were lower than those of T1 and T2, respectively. In general, the effect of Gibon package fertilizers and Jingu package fertilizers are superior to that of the conventional fertilization, however, the Gibon package fertilizers has lower cost and a higher economic benefit compared with Jingu package fertilizers, and could better attain the goal of cost-efficiency.
