Resource Utilization of Medicinal Plant Erigeron breviscapus Cropland

Used Erigeron breviscapus Rhizosphere soil aqueous extract and mix soil (E. breviscapu Rhizosphere soil and vegetable field ) to cultivate three crops (Pisum sativum Linn, Chinese cabbage, Brassica campestris L), got investigated physiological and biochemical indicators of the above three crop seeds. The results show that seed germination rates, root length and fresh weight decreas with the aqueous extract concentration and rhizosphere soil proportion increase after Pisum sativum Linn was used. All of these physiological indicators of Brassica campestris clearly are not stable. Meatime, E. breviscapu Rhizosphere soil aqueous extract and mixed soil promote Chinese cabbage growth. Allelopathic sensitivity indexes of Chinese cabbage are positive value. So, Chinese cabbage can be as appropriate rotation crop with E.breviscapus. E.breviscapus cropland can also use to plant Chinese cabbage to achieve cultivated resource utilization.
