干扰百草枯除草效果的实验研究

The explore the herbicidal effect of paraquat interference

目的本研究探讨不同化合物对百草枯除草效果的干扰,旨在寻找能供临床使用的降解百草枯毒性的洗胃剂,以利于临床有效合理地早期治疗百草枯中毒。方法将试验草地分为,乙醇、漂白土、活性炭、清水、碳酸氢钠等干扰区和一个百草枯除草对照区,直观植物损伤的程度,判断化合物对百草枯的降解能力。结果碳酸氢钠区与百草枯对照区比效果显著(P<0.01),有明显干扰百草枯除草能力的作用。结论早期使用碳酸氢钠液冲洗有明显地水解百草枯的作用。

Objective This study aims to explore the herbicidal effect of paraquat interference, through observation and control , to find a drug or drugs which can effectively get paraquat toxicity disarmed or degradated. So early treatment of paraquat poisoning in clinical can be reasonably and effectively. Methods A zoning turf test, the interference group and a number of the control group. According to the physical characteristics of paraquat and commonly used drugs, we choose the interference ： alcohol, fuller earth, sodium bicarbonate, and activated carbon. Then judgment of the extent of damage can be got by observe and compare with the control. Results According to the observation of standards, effects of sodium bicarbonate group was significant, with a clear ability to interfere with the role of paraquat weeding. Conclusion Early use of sodium bicarbonate rinse obviously disarm paraquat role.
