摘要:
本研究采用室内生测方法,测定了水稻秸秆水浸提液对杂草和作物发芽率的影响,研究了不同浓度浸提液对杂草和作物的化感作用。结果表明,可以把水稻秸秆作为硬草和王不留行除草剂的研究植物;在研究水稻秸秆提取液作为狗尾草有效的除草剂时,应使用浓度≥0.04 g/mL的提取液。同时,还研究了秸秆提取液对作物的除草安全性。研究结果表明,种植韭菜、番茄和萝卜时不可以使用水稻秸秆提取液研制的除草剂;种植小麦时可以使用浓度<0.01 g/mL的水稻秸秆提取液研制的除草剂;在种植白菜时可以使用浓度<0.02 g/mL的水稻秸秆提取液研制的除草剂。

Abstract:
In this research,the effects of water extract of rice straw on the germination rate of weeds and crops were studied by bioassay method,and the allelopathy of different extracts on weeds and crops was studied.The results showed that the rice straw could be used as bio-herbicides against the weeds of Sclerochloa dura and Vaccaria segetalis,and when the rice straw extract was used as the effective herbicide against green bristlegrass,the concentration should be≥0.04 g/mL.When the rice straw extract was used as herbicide,the safety for crops was also studied.The results were as follows:the herbicide produced by rice straw extract should not be used in the cultivation of leek,tomato and radish,and the concentration<0.01 g/mL could be used on wheat,while<0.02 g/mL could be used on Chinese cabbage.
Key words:  rice straw extract  weed  inhibition effect  allelopathy
