Abstract: The Taishan sealwort likes wet and resistants cool, evades the glare to fear dry, The purpose of this study is to evaluate the influence of the light intensity to taishan sealwort’s growth and yield. Is highest by the apple forest interplanting sealwort addition output and the new rhizome polysaccharide content respectively reaches 19.4%, 21.8%,40% transmittance visor net visor processing sealwort addition output and the new rhizome polysaccharide content is lowest, has 13.4% and 11.0%. Under the visor net the sealwort average transpiration rate is open-air cultivates 81.4%, explained that the Taishan sealwort does not suit the open-air growth.The net photosynthesizes of different leaves drops rapidly when there is more than 20 piece of leaves,you may cut the terminal bud in production for the promotion underground portion growth. The shade culture may reduce the occurrence probability of the sealwort spot leaf effectively, it is lightest by 40% diaphanous cultivation, preventive effect reaches 68.4%. The visor net cover cultivation causes the sealwort output distinct enhancement,which is best by 40% diaphanous processing production increases effect, increases production 27.71%, the volume variance reaches the extremely remarkable level with the CK processing and 25% shade processing.
