项目摘要

From the experimental results of the dropping experiment of ozonized water on Jew's mallow, ozone has the efficiency to inhibit the growth of Jew's mallow. Though ozone didn't eliminate Jew's mallow completely, it will make weeds on what ozone is dropped be inhibited from their healthy growth and crops have the upper hand in the optical competition. Additionally, if the efficiency of ozonized water to transform the shape of Jew's mallow is proved to be useful for the other plant, especially weeds, it will be possible to reduce the amount of the weeds' photosynthesis and finally to restrain the influence of the weed damage.Besides, the experimental results under the condition that the concentration of ozonized water was kept to be constant and only the dropping rate of ozonized water per day was changed showed that the difference between the growth of Jew's mallow in the plot of I time per day and that in the plot of 5 times per day was significant. Therefore, it will be said that the total amount of ozonized water dropped on Jew's mallow per day influences the growth of the plant.As compared with destruction power of herbicides, it would have to be said that the power of ozonized water is very poor. But considering the merit of ozonized water that ozonized water does not leave the toxic substances behind crops, does not pollute the ground water and the soil, and has little influence to pursuers' health on weeding, the treatment of weeds using ozonized water can be the effective weed control method what replaces broadcasting of herbicides.

从臭氧水对黄花葵的滴加试验结果来看，臭氧对黄花葵的生长具有抑制作用。虽然臭氧并没有完全消灭犹太人的锦葵，但它会使臭氧投放的杂草受到抑制，使作物在光学竞争中占据上风。此外，如果臭化水对其他植物，特别是杂草也有一定的改造效果，那么就有可能减少杂草的光合作用，最终抑制杂草的危害。此外，在保持臭氧浓度不变，仅改变臭氧水的日滴速的情况下，试验结果表明，在每天1次的情况下，与每天5次的情况下，朱砂的生长差异显著。因此，可以说，每天洒在犹太锦葵上的臭化水总量会影响植物的生长。与除草剂的破坏力相比，臭化水的杀伤力应该说是很差的。但考虑到臭氧化水不会留下有毒物质，不污染地下水和土壤，除草时对人们的身体健康影响不大等优点，用臭氧化水处理杂草可以成为替代喷洒除草剂的有效除草方法。
