This study aimed to investigate the feasibility of using pig manure and coconut coir as raw materials to configure seedling substrates.Red Pearl tomato variety was selected as the test material.Four materials,including pig manure,coconut coir,earthworm castings,and vermiculite,were selected and combined to form seedling substrates.The physical and chemical properties of the sub-strates and the physiological indicators of tomato seedlings were studied under different ratios.The grey relation analysis was used to comprehensively analyze the seedlings under different substrate treatments.The results showed that the tomato seedlings under the T4 treatment(pig manure:coconut coir∶earthworm castings∶vermiculite=4∶3∶1∶1)had the best plant height and stem diameter 50 days after sowing.The soluble sugar content,soluble protein content,and root activity of the tomato seedlings under the T4 treatment were significantly higher than those of the other substrates.The grey relation analysis results indicated that T4 had the highest evaluation.Pig manure and coconut coir can be used as raw materials to configure seedling substrates,and the optimal ratio is pig manure:co-conut coir∶earthworm castings∶vermiculite=4∶3∶1∶1.This study further broadens the ideas for formulating vegetable seedling sub-strate recipes.
