Abstract: In north of China，film covering soil ridge was widely used for greenhouse vegetable production.A novel method of film-covering cultivation ridge-ridge substrate-embedded cultivation（RSC）was put forward，and two types were derived which included RSC-P（PE groove-embedded）and RSC-W（wire netting groove with plastic film-embedded），and then effect of four kinds of film covering cultivation ridges included SR and PEG on the growth of sweet pepper seedlings were studied.Test results showed that three kinds ridges of RSC-P，RSC-W and PEG compared to SR could improve height，leaf number and leaf chlorophyll content of sweet pepper seedlings significantly，heights were higher by 26%，27.5% and 32% than SR，respectively，leaves of sweet pepper seedlings were more than SR，and the content of chlorophyll of sweet pepper seedlings were higher than SR.Experiment showed that three kinds of film covering cultivation ridge which we set could significantly promote growth of sweet pepper seedlings.
