Abstract:
Objective:To explore the allelopathic effect of garlic volatiles on Angelica sinensis by studying the allelopathic effect of both living garlicand isolated garlic sprout volatiles on A. sinensis, and provide certain theoretical basis for Angelica garlic interplanting mode to alleviate the stress of continuous cropping A. sinensis. Method:Through the determination and analysis of the growth indexes and leaf protective enzyme system of A. sinensis，the adaptability of A. sinensis to continuous cropping stress and non-continuous cropping stress environment under the influence of the volatiles of living garlic and isolated garlic sprout as well as the mechanism of resistant growth and development were discussed. Result:The overall analysis showed that the growth index and leaf protective enzyme activity of isolated garlic sprout with alleloinductive treatment（DC2）under continuous cropping stress were increased by 17.51% and 48.34% respectively as compared with those under single cropping（CK1）. The growth index and leaf protective enzyme activity of angelica under continuous cropping and intercropping（LC2）were increased by 16.63% and 36.65% as compared with those under monocrop cropping（CK2）. Those indicated that the volatiles of isolated garlic sprout had more significant effect than those of live garlic on alleviating the stress of continuous cropping of A. sinensis. Conclusion:Regardless of the presence of continuous cropping obstacle，appropriate concentrations of living garlic and isolated garlic sprout volatiles had an allelopathic promoting effect on angelica root growth index and leaf protective enzyme activity，and the effect was more obvious in continuous cropping stress conditions，so intercropping garlic has a certain role in alleviating angelica's continuous cropping stress.
