Effect of Different Fertelizationon on Yield and Quality of Cherry Tomato in Substrate Culture

Under the condition of the same nutrition solution concentrations in drip irrigation,the effect of substrate cul-ture on the yield and the quality of cherry tomato by adding different fertilizer ahead or spraying foliar in the growth peri-od was studied.The results showed that the yield and the quality can be both increased by applying foliar and organic fertilizer.The best organic fertilizer treatment increased the yield of cherry tomato by 13.6%,disinfect chicken mannure treatment increased the yield of cherry tomato by 8.9%.The quality can be improved by applying organic fertilizer and the chemical fertilizer at the same time;soluble solids can be improved by 2.08%-6.5%;VC content can be improved by 4.1%-11.3%,and at the same time,nitrate content was decreased by 8.5%-14.7%.The foliar fertilizer promoted the botany characters such as growth of plant height and stem diameter better than the other two.
