洋葱如何消毒

1. 洋葱中含有一定的钙质。洋葱中含有植物杀菌素如大蒜素等,因而有很强的杀菌能力。

2. 洋葱所含的微量元素硒是一种很强的抗**剂,能清除体内的自由基,增强细胞的活力和代谢能力,具有防癌抗衰老的功效。葱蒜类蔬菜种子在贮藏保管过程中易吸附携带多种病菌,农民朋友在葱蒜类蔬菜播种时,若按下列方法进行种子消毒处理,可有效灭杀多种病菌,确保齐苗、壮苗。

将洋葱种子用300倍的40%福尔马林稀释液浸泡3小时,浸后用清水洗净,晾干后播种,以鳞茎方式繁殖的,可将鳞茎放入40℃~50℃温水中浸泡90分钟,然后置于泠水中散热,晾干后栽种,可有效灭杀洋葱种子携带的炭疽病及黑斑病病毒。将洋葱种子用50%克菌丹可湿性粉剂,或50%六氯代苯粉剂,或50%福美双可湿性粉剂(上述药剂任选一种即可)按照1:4的药、种比例均匀拌处,可消除洋葱种子携带的黑粉病病菌。以鳞茎方式繁殖的洋葱,可将鳞茎放入40℃温水中浸泡1.5个小时或在43.5℃的温水中浸泡2个小时,浸后立即用冷水散热,晾干后栽种,可防治茎线虫病病菌。用50℃温水浸泡洋葱种子25分钟,浸后置于冷水中降温,晾干后播种;用鳞茎繁殖的洋葱,可将鳞茎置于45℃温水中浸90分钟,浸后置于冷水中降温,晾干后栽种,可消除洋葱种子携带的霜霉病病菌。

洋葱可以杀菌消毒

In 1919. When the flu killed 40 million people, there was this doctor that visited the many farmers to see if he could help them combat the flu. Many of the farmers and their family had contracted it, and many died.1919年。当流感造成了四千万人死亡时,有一位医生到各地农场去探视,看是否可以帮助人们战胜流感。很多农民和他们家庭感染了流感,很多人因此而死亡。

The doctor came upon this one farmer, and to his surprise, everyone was very healthy.

这位医生来到一家人家。出乎预料,这家的每一个人都非常健康。

When the doctor asked what the farmer was doing that was different, the wife replied that she had placed an unpeeled onion in a dish in the rooms of the home (probably only two rooms back then).

医生询问这家的做法与其他人家有何不同,这家的妻子说她在家里的每一个房间(那时大概也就是两间吧)里放置了一颗没有剥皮的洋葱。The doctor couldn’t believe it, and asked if he could have one of the onions, and place it under the microscope.医生无法置信,因此就问是否可以要一颗洋葱以便放在显微镜下观察观察。She gave him one, and when he did this, he did find the flu virus in the onion.她给了他一颗。医生观察时真的在洋葱上发现了流感病菌。It obviously absorbed the bacteria, therefore keeping the family healthy.

显然,洋葱吸收了病菌,因此让这家人保持健康。Now, I heard this story from my hairdresser in Arizona.如今,我从亚利桑那州我的理发师那里听到类似的故事。She said that several years ago, many of her employees were coming down with the flu, and so were many of her customers.她说几年前她的很多雇员感染流感,她的很多顾客也是如此。The next year, she placed several bowls with onions around in her shop. To her surprise, none of her staff got sick. It must work . . .次年,她在她的理发店里放了几个果盘,里面放了一些洋葱。令她吃惊的是,她的员工没有一个生病的。看来洋葱真的起作用… (And no, she is not in the onion business.)(真的,她并不做洋葱的生意。)The moral of the story is, buy some onions and place them in bowls around your home.故事的核心是,买一些洋葱吧,把它们摆放在你的家里的果盘里。If you work at a desk, place one or two in your office, or under your desk,or even on top somewhere.如果你是坐办公室的,在你的办公室里,或者办公桌下面,或者在柜子顶部放置几颗洋葱吧。Try it and see what happens.试试看效果怎么样。We did it last year, and we never got the flu.我们去年做了,没有人得流感。If this helps you and your loved ones from getting sick, all the better.如果这样做可以帮助你和你所爱的人不感冒,那就太好了。If you do get the flu, it just might be a mild case.如果你仍然得了感冒,也许会是比较轻微的症状。Whatever, what have you to lose?不管结果如何,你又会有什么损失呢? Just a few bucks on onions!除了几颗洋葱之外! Now there is a P. S. to this for I sent it to a friend in Oregon who regularly contributes material to me on health issues.下面是后续。我把这个送给我在奥尔良的朋友,她经常给我一些健康方面的建议。She replied with this most interesting experience about onions:她回复说了关于洋葱的最有趣的实验:I don’t know about the farmer’s story, but I do know that I contracted pneumonia, and needless to say I was very ill.我不知道那个农民的故事,但是我知道我得了肺炎。无需说,我病的不轻。I came across an article that said to cut both ends off an onion, put one end on a fork, and then place the forked end into an empty jar, placing the jar next to the sick patient at night.我读到一篇文章,建议把洋葱的两头切掉,插在叉子上,然后把叉子放在花瓶里,晚上放在病人身旁。It said the onion would be black in the morning from the germs.据说,洋葱会因为病菌而在次日清晨变黑。Sure enough, it happened just like that.果然,事情跟说的完全一样。The onion was a mess, and I began to feel better.洋葱看起来糟透了,但我却开始好起来。Another thing I read in the article was that onions and garlic placed around the room saved many from the black plague years ago.那篇文章还谈到放在屋子里的洋葱和大蒜在多年前的黑死病中救了很多人的命。They have powerful antibacterial, antiseptic properties.

洋葱的病虫害有哪些

洋葱常见病害有霜霉病、紫斑病、灰霉病和炭疽病等。霜霉病,在发病初期用80%乙磷铝500倍液+64%杀毒矾500倍液、或70%甲霜灵锰锌或乙磷铝锰锌500倍液、或72%杜邦克露600-800倍液、或72.2%普力克700倍液、或绿乳铜800倍液、或特立克800倍液、或克霜氰600倍液、或75%百菌清800倍液等。紫斑病,在发病初期用78%科博可湿性粉剂500倍液、或41.5%扑霉灵1500倍液、或75%百菌清可湿性粉剂600倍液、或64%杀毒矾可湿性粉剂500倍液、或50%异菌脲,可湿性粉剂1000倍液等。 灰霉病,发病初期,用25%咪鲜胺乳油1000倍液、或施佳乐悬浮剂1200倍液、或速克灵3000倍液、或50%扑每因可湿性粉剂1500倍液等。 炭疽病,在发病初期用10%世高水分散颗粒剂1500–2000倍液、或用25%咪鲜胺乳油1000倍液、或50%炭疽福美可湿性粉剂500-800倍液。  在洋葱生产过程中容易出现很多病虫害,要采取“预防为主,综合防治”的植保方针。 

在洋葱生产过程中容易出现的虫害主要有葱潜叶蝇、葱蓟马、葱蝇等。叶片长出2~3个时出现葱潜叶蝇,应用乐果800~1000倍液及时防治。4~5片叶时,叶腋紧凑便出现葱蝇和葱蓟马,可用灭杀毙6000倍液、乐果1000倍液、辛硫磷1000倍液防治。 

进入雨季后虫害较少,开始出现病害,所以在进入雨季之前的6月中、下旬开始喷药预防。洋葱在生产上常见的病害有紫斑病、灰霉病和软腐病。紫斑病可用75%百菌清500~600倍液、50%扑海因1500倍液、64%杀毒矾500倍液隔7~10天喷1次,连续防治3~4次。灰霉病可用扑海因1500倍液、50%速克灵2000倍液7~10天喷1次,连续喷3~4次防治。软腐病可用72%农用硫酸链霉素可溶性粉剂4000倍液、新植霉素4000~5000倍液视病情隔7~10天喷1次或2次进行防治。更多病虫害防治办法尽在植物网。
