[Objective] The research aimed to provide a basis of silicon fertilizer in tomato production and wider fields. [Method]The effects of silicon fertilizer on yield,quality and fertilizer utilization rate of tomato(jinpeng No. 1) were researched. The completely randomized design was used in this experiment. [Result]Silicon fertilizer increased the yield of tomato significantly. Applying silicon fertilizer(N-P2O5-K2 O 20-10-20)could increase the yield by 16. 16% compared with the control,and increased by 5. 45%...
