Weed Control System by Damaging Growth Point

从臭氧化水在锦葵上滴下实验结果来看，臭氧对锦葵的生长有抑制作用。虽然臭氧并没有完全消灭犹太人的锦葵，但它会使杂草在臭氧的影响下健康生长，使作物在光竞争中占据上风。另外，如果臭氧水改变锦葵形状的效率被证明对其他植物，特别是杂草有用，就有可能减少杂草的光合作用量，最终抑制杂草危害的影响。另外，在保持臭氧水浓度不变，只改变每天臭氧水滴下速率的条件下，实验结果表明，每天1次的小区与每天5次的小区中，犹太锦葵的生长差异显著。因此，我们可以说，每天落在犹太锦葵上的臭氧水总量会影响植物的生长。与除草剂的破坏力相比，臭氧水的破坏力是非常弱的。但考虑到臭氧水在除草时不会将有毒物质残留在作物体内，不污染地下水和土壤，对除草者健康影响小等优点，臭氧水处理杂草可以成为替代除草剂撒播的有效除草方法。

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.
