小麦化感作用的种群生态位调节及其生态效应探讨

摘要

The ecological effects, involved in control of weeds using wheat allelopathic potential, were discussed in view of allelopathy, niche theory and their relationships. The ecological effects of wheat allelopathic potential and its key scientific problems, after wheat allelopathic varieties were released, were explored in the study, including the growth and withering of weed populations and changing trend of its niche. It was expected to provide the ecological basis and important scientific information for effective control of weeds by using allelopathic wheat varieties and its allelopathic potential for suppression of weeds.%本文针对利用小麦品种化感抑草潜力控制杂草所涉及的生态效应问题,从化感作用、生态位理论及其关系的角度展开论述,探讨了小麦化感抑草潜力及化感品种释放后的麦田杂草种群消长动态及生态位变化趋势等生态效应及关键科学问题,以期为合理利用小麦化感作用及其化感品种抑草潜力有效控制杂草提供生态依据和重要基础信息.
