高粱专用除草剂二氯莠去津喷后为何叶子发黄,可以自己变绿吗?

高粱专用除草剂二氯莠去津是一种广谱杂草除草剂,主要通过抑制植物体内的焦亚硫酸脱氢酶来杀灭杂草。当高粱叶子接触到该除草剂后,除草剂会进入叶片并抑制植物的光合作用,导致叶子发黄。 一旦高粱叶子发黄,通常无法自己变绿。这是因为二氯莠去津会在高粱叶子内形成比较稳定的结合物,这些结合物对光合作用的恢复起到抑制作用,从而导致叶片无法恢复正常的绿色。 因此,一旦高粱叶子发黄,就意味着受到了较为严重的伤害,无法通过自身机制恢复。为了确保作物的生长和产量,建议及时处理黄叶,例如剪去受损的叶片,以促进新叶的生长。同时,在使用除草剂时要按照产品说明书上的正确用量进行喷洒,避免超量使用或过早施用。

destroy,damage,ruin有什么区别
"destroy," "damage," and "ruin" are all verbs that are used to describe the negative impact on something. However, there are some differences in their meanings. 1. Destroy: When something is destroyed, it means it is completely ruined or annihilated. It suggests that the thing no longer exists in its original form and may be irreparable. For example, a building can be destroyed by fire or an object can be destroyed in an explosion. 2. Damage: Damage refers to the harmful effect or injury caused to something. However, it does not necessarily mean that the thing is completely destroyed. Damage implies that there is harm or impairment, but it can often be repaired or fixed. For example, a car can be damaged in an accident, but it can still be repaired. 3. Ruin: Ruin means to cause severe damage or destruction to something that may lead to its downfall or degradation. It implies a more severe and irreversible harm, often affecting the overall condition or functionality of something. For example, an economic crisis can ruin a country's economy or a bad decision can ruin a person's reputation. In summary, "destroy" suggests complete annihilation, "damage" implies harm or impairment that may be repairable, and "ruin" refers to severe and often irreversible damage or destruction.
