[Biological and Phenological Properties of Salvia miltiorrhiza f. alba for Anti-continuous Cropping].

Morphological characteristics and phenological phase of Salvia miltiorrhiza f. alba for anti-continuous cropping was studied in the field.The data of fixed plants of different stages were collected and analyzed.The resistance of the strains for anti-continuous cropping was obviously higher than the others. The phenological phase of strains for anti-continuous cropping was divided into seedling stage, elongation stage,flower stage, fructification stage,root enlargement stage and dead stage. The whole development period was divided into the vegetative growth and reproduction growth by the flower stage.From the appearance characteristics and resistance observation, the growth of Salvia miltiorrhiza f. dlba for anti-continuous cropping was better than the other strains in the next year.
