Effects of Different Substrates on Pepper Plug Seedling Growth

The quality of substrate is a key factor for pepper plug seedling growth.In this study,six commercial substrates usually used in Fujian Province,and three compound substrates mixed with vermiculite,peat soil and perlite were tested for pepper plug seedling growth.Some physical and chemical properties of the seedling substrates were determined and the growth of pepper seedling was also studied.The results showed that different substrates significantly impact on the morphological index of pepper seedling.The Baili and Chaimihe substrates performed better than the other 7substrates with respect to pepper seedling plant height,stem diameter,canopy,sound seedling index and G value.In conclusion,Baili and Chaimihe substrates were suitable for pepper plug seedling growth in Fujian Province.
