Abstract: Effects of substrates with different hickorg epicarp contents on the plant growth, yield and fruit quality of protected tomato were investigated in the present study. The local soil was set as the control, and two compound substrates were selected. One compound substrate was manure-hickorg epicarp with volume ratio of 7:3, and the other one was manure-hickorg epicarp-rice hull with volume ratio of 7:2:1. We found that in comparison with local soil, the bulk density and EC of both substrates decreased significantly, and soil porosity, pH and organic matter content increased notably. Both compound substrates improved the yield and fruit quality significantly. The tomato yield in compound substrate of manure-hickorg epicarp reached 22.88 kg·m-2, and increased by 35.9% compared with the control. Besides, in comparison with the control, the content of soluble sugar, soluble protein and Vc in tomato fruits grown in compound substrate of manure-hickorg epicarp increased by 72.1%, 23.6% and 122.1%, respectively. Meanwhile, the yield of tomato in compound substrate of manure-hickorg epicarp-rice hull reached 21.86 kg·m-2, and increased by 29.9% compared with the control. Furthermore, the content of lycopene in tomato fruits grown in compound substrate of manure-hickorg epicarp-rice hull increased by 18.8%. Therefore, both compound substrates can be used in protected cultivation of tomato.
