Abstract This experiment using biogas residue and coal cinder to study their effects on the growth and yield of tomato in greenhouse.The results showed that the physical and chemical properties of the mixed substrates could meet the requirement of tomato plant growth.Biogas residues could accelerate tomato growth,improve its yield and quality.Among all treatments,the treatment of 3 biogas residue+1 coal cinder(V/V)had achieved the highest root activity and the highest yield(per plan of the first three fruit cluster yields 0.93 kg)and the highest ratio of sugar to acid(6.24).
