Abstract：Torreya grandis is a unique economic tree species in China,and its extracts contain various active ingredients.As a raw material,it has development value in various fields such as agriculture,chemical industry,food,and medicine.To investigate effects of T.sinensis extract on plant growth and disease prevention and control,this study used non-heading Chinese cabbage as the test material,the chemical composition and content of T.sinensis extract were determined by gas-mass spectrometry.The effects of T.sinensis extract on the yield,commodity and soft rot resistance of non-heading Chinese cabbage were determined by spraying different concentrations of T.sinensis extract during the growth period of non-heading Chinese cabbage.The results showed that the chemical components with relatively high relative mass fractions(content≥1%)in T.sinensis extract,including 11 substances such as D-limonene and α-pinene.The height,number of leaves,individual weight,and yield of non-heading Chinese cabbage treated with the original solution of T.sinensis extract were significantly higher than those of the control,which could improve the yield and marketability of non-heading Chinese cabbage and prevent the occurrence of soft rot disease,with a control effect of over 79%.
