Abstract:
Taking Pogostemon cablintissue culture seedlings and Perilla frutescens seedlings as materials and adopting a method of the pot culture in house，there were 3 treatments,continuous cropping group(only the second crop Pogostemon cablin)，intercropping group(the second crop Pogostemon cablin intercropping with perilla frutescens),control group(only the first crop Pogostemon cablin),and the agronomic traits,the content of malondialdehyde (MDA) in leaves,microbial quantities and soil enzyme activities in rhizosphere soil,the content of patchouli alcohol and pogostone in Pogostemon cablin were determined,in order to study the relieving effect of Pogostemon cablin intercropping with Perilla frutescens on its continuous cropping obstacle.The results showed that after 90 days of cultivation，the agronomic traits (plant height，dry weight，fresh weight，main root length) and the content of patchouli alcohol and pogostone were significantly higher in the intercropping group than in the continuous cropping group (P<0.05),and there were no significant differences between intercropping group and control group.For the content of MDA in the leaves，intercropping group was reduced by 33.74% (P<0.05) compared with the continuous cropping group，but there was no significant difference between intercropping group and control group.Compared with the continuous cropping group,the number of soil bacteria and actinomycetes in Intercropping group increased by 30.35% and 66.67% (P<0.05)，respectively,and the intercropping group increased by 21.24% and 75.00%(P<0.05)，respectively,compared with the control group.There was no significant difference in the number of soil fungi between the intercropping group and the control group.The activities of soil invertase，urease and acid phosphatase in intercropping group were increased by 25.50%，30.58% and 50.22% (P<0.05)，respectively than the continuous cropping group.The soil invertase activity was not significant difference between the intercropping group and the control group.While urease and acid phosphatase activities in intercropping group were increased by 7.44% and 41.92% (P<0.05)，respectively,compared with the control group.It was concluded that the intercropping of Perilla frutescens could alleviate the continuous cropping obstacle in Pogostemon cablin to a certain extent.
