Abstract:
Taking‘Fendeshuai No.2’tamato variety as materials，straw biogas and perlite were used as composite matrix，different nutrient solution formulations was designed by the principle of material readily available，to screen for easy plug seedling nutrient solution formula，and tomato plug seedlings trial with northern nutrient solution was used as a control formula.The results showed that，after sowing 13-28 days，treatment T2（152.3 mg/L urea，508.76 mg/L monopotassium phosphate，291.67 mg/L potassium sulphate，707.00 mg/L calcium nitrate）in plant height，leaf area，shoot fresh weight，root fresh weight all showed no significant difference with CK，after sowing 33 days，treatment T2 in plant height，stem diameter，leaf area，shoot and root fresh weight were slightly higher than CK，shoot and root dry weight showed little difference with CK.Nutrient solution formula T2 had the similar effect on plug seedling production with CK，and didn’t contain potassium nitrate，ammonium nitrate and phosphoric acid，it was easy to configure with raw materials and suitable for promotion in production applications.
