摘要
利用不同品种水稻材料对杂草的抑制作用差异，筛选具有显著抑草性能的水稻新品种，是解决水稻田杂草危害问题的
重要途径。本研究以多年田间对比试验筛选出具有显著抑草性能的抑草稻为试验材料，利用实验室盆栽培养法，获得苗期叶
片提取液、根提取液、根与根系土壤共同水浸液和非根系土壤水浸液，再分别利用上述水浸液培养皿滤纸培养法培养莴苣种
子，并以蒸馏水为对照，观察上述溶液对莴笋生长的抑制效果。结果表明：不同水浸液之间，抑制效果差异明显。其中，不
同浓度叶片提取液和非根系土壤水浸液的抑制效果与大田鉴定结果不一致，根提取液抑制效果则不明显，而只有根与根系土
壤共同水浸液对莴笋根长的抑制率效果与大田鉴定相一致，因而可以作为大田筛选鉴定抑草性能的辅助方法。本研究旨在获
得抑草稻抑草性能快速筛选方法，并探明抑草途径。

Abstract
Screening of new rice varieties with significant allelopathy among different rice materials via the differences in
allelopathic effect to weeds was an important way to solve the problem of rice weeds’ hazardness. In this study, new varieties with
significant allelopathy obtained from years of field comparison test were selected as experiment materials. Based on potted plant
cultivation in the laboratory, different extracts were obtained from leaf, root, root and soil of root system, and soil of non-root system.
Then we used these extracts to cultivate lettuce seeds with filter paper method, contrasted by distilled water, to observe the effects of
their allelopathy on lettuce seeds growth. The results indicated that effects of their allelopathy seem significantly different among
individual water extracts. The allelopathic effect of extracts from leaf and soil of non-root system in distinct proportions were
different from the field selection results. The allelopathic effect of root extracts was not significant. The allelopathic effects of
extracts from root and soil of root system was in accordance the field selection results, which, therefore, can be used as an assistant
method for field selection and breeding. The purpose of this research was to obtain a fast selecting method for the allelopathic effect,
and detect the pathway of allelopathy.
