奇善宝对世玛除草剂在小麦上的药害的恢复效应研究

在冬前麦田化学除草过程中，除草剂药害经常发生，以世玛等除草剂产生的药害较多，研究其缓解技术十分必要。针对世玛除草剂药害麦田，通过叶面喷施海洋寡糖生物制剂奇善宝，研究其对受害小麦恢复效应；受除草剂药害小麦叶面喷施奇善宝后7天，小麦植株开始有别于对照，25天后处理株高、绿叶数量、次生根显著高于对照，处理产量增加了549.30 kg/hm2，增产9.7%。同时喷施奇善宝在一定程度上改善籽粒品质，稳定时间增加15.7%，吸水率较对照降低1.4%，硬度、沉降值、出粉率和拉伸参数差异不显著；奇善宝可显著缓解除草剂对小麦的危害程度，有显著的增产效应，并在一定程度上改善籽粒品质。

Recovery Effect of Qishanbao on Wheat Harmed by Shima Herbicide

Abstact: Aiming at the phytotoxicity caused by spraying herbicide Shima and Kuoji on wheat before winter, the study is focused on the victim recovery effect of wheat, by foliar spraying Qishanbao, a biologic of marine oligosaccharide, on wheat. 7 days later, after foliar spraying Qishanbao, the wheats poisoned by herbicide Shima and Kuoji started to differ from control. 25 days later, the height, the number of green leaves and the secondary roots are significantly higher than control, and the yield of experiment increased by 549.30kg/hm2, an increase of 9.7%. Meanwhile, spraying Qishanbao improved grain quality to a certain extent. It increased stable time by 15.7%, and decreased water absorption by 1.4% compared to control. There was no obvious difference in hardness, sedimentation value, flour yield or extensograph parameter.Keywords: Wheat, QiShanbao, Herbicide, Phytotoxicity, Yield
