Abstract:
In this study,the effect of vermicompost dosage (EM1，16.67 g?kg-1 soil；EM2，20.00 g?kg-1 soil ;EM3，26.67 g?kg-1 soil) on tomato growth and yield and quality was conducted comparing with the treatments of cattle manure (CM) and no fertilizers (CK) applied.Pot experiments were used,in order to get the best amount of vermicompost.The results showed that with the increasing of dosage of vermicompost,plant height,stem diameter increased.From April 12th for the first time on May 25th measured plant pinch point,plant height growth rate of cattle manure (CM) was 61.9% higher than vermicompost (EM2),but the stem diameter growth rate of EM2 was 18.8% higher than the CM.Among all treatments,EM1 treament had the most of the small tomatoes (fruit diameter<5.8 cm),but the highest yield per plant.Comparing with CK,EM1 was 1.23 times of the yield.With the increasing of dosage of vermicompost the content of the number of small fruit,organic acids and soluble sugar increased,but yield of per plant,the value of the tomato (5.8 cmfruit diameter6.4 cm) and sugar-acid proportions decreased.The treatment of EM2 had the highest content of vitamin C,and was 31.95 mg?(100g)-1.The yield,value and sugar-acid ratio of tomato of EM2 treatment were slightly higher than the same fertilizer rate of CM.The suitable dosage of vermicompost was 16.67-20.0 g?kg-1 soil for greenhouse tomato.
