摘  要:
为利用铁杆蒿开发生物除草剂,以小麦品种小偃22为材料,研究了不同浓度铁杆蒿全草浸提液对小麦种子萌发和幼苗生长的化感作用。结果表明:经铁杆蒿全草浸提液处理后的小麦种子,其萌发率和发芽指数随浸提液浓度的升高而显著降低,并且对小麦种子萌发速度的抑制作用强于对其萌发率的抑制作用;高浓度铁杆蒿全草浸提液对小麦种子初生胚根和幼苗的生长表现出较强的抑制作用,而低浓度铁杆蒿浸提液表现出促进作用。其中,浓度为0.05和0.01g·mL-1的铁杆蒿全草浸提液能够显著增强小麦根系活力。

摘  要:
In order to develop biological herbicide with Artemisia sacrorum,taking wheat variety Xiaoyan 22 as test material,the allelopathy of different water extract solution concentration of Artemisia sacrorum on wheat seeds germination and seedling growth was studied.The results showed that seeds soaking with different concentration water extract solution of Artemisia sacrorum,the germination rate and germination index of wheat seeds decreased dramatically with the increasing of water extract solution concentration.Moreover,the inhibiting effect on the speed of wheat seeds germination was stronger than that of wheat seeds germination rate.Meanwhile,higher extract solution concentration had inhibiting effect while lower extract solution concentration had promotion effect.When extract solution concentration of Artemisia sacrorum was 0.05 and0.01g·mL-1,root activity improved obviously.
