就是看觉着玫瑰好看,所以种了几棵玫瑰,现在发现有那种绿虫在搞破坏,不知能不能开出花来,回家赶紧试试大蒜水,希望能解决问题
哦,可惜我家的地不够大,番茄跟玫瑰一起,这番茄不知是不是能把玫瑰挤开了从网上看的,番茄种在玫瑰旁边可以帮玫瑰解决黑斑。“Oddly enough, tomatoes allegedly prevent black spot, but not many people will be inclined to combine roses and tomatoes.” 看链接http://gardening.about.com/od/rose1/a/Rose_Companions.htm。
昨天查什么和番茄种一起好,看到的,在这里“Roses - Protects roses from black spot. You can interplant or use a spray. Spray: Liquify tomato leaves and then dilute them with 4-5 pints of water Add a tablespoon of cornstarch. Use to spray on rose leaves, when you can't plant tomatoes next to them. NOTE: It could be the cornstarch that does the trick here. Recent studies are showing cornmeal is an effective fungicide on tomatoes.” 从这个链接里看的,http://gardening.about.com/od/totallytomatoes/qt/Tomato-Companions.htm
你是说放个盆栽的番茄在玫瑰中间?我的玫瑰都集中在一块不大的地方,每棵之间也没留很远的距离,所以中间就只种了点小花小草什么的。有两棵玫瑰还被挤到别的角上去了。如果番茄叶管用,那倒是太好了!目前喷了大蒜叶,似乎还有绿虫子在上面,特别是那些长了花苞的玫瑰,虫子特喜欢 。前天把那些带黑斑的叶子都剪了,今天又看到有新的了,而且有的花苞都有斑点,很头大!你把一颗番茄种它们前边不就行了,或者你那个可以盆栽的。何况种不了还可以试试番茄叶子碾碎加水喷亚。
那个英文说Spray: Liquify tomato leaves and then dilute them with 4-5 pints of water Add a tablespoon of cornstarch. Use to spray on rose leaves, when you can't plant tomatoes next to them. NOTE: It could be the cornstarch that does the trick here. Recent studies are showing cornmeal is an effective fungicide on tomatoes. 你要是现在没番茄叶,索性直接搞点淀粉水喷上看看。不过这个我是真没经验。我的玫瑰池子估计后年能有,还有两年学习时间。你先试验着,到时候找你学习。你是说放个盆栽的番茄在玫瑰中间?我的玫瑰都集中在一块不大的地方,每棵之间也没留很远的距离,所以中间就只种了点小花小草什么的。有两棵玫瑰还被挤到别的角上去了。如果番茄叶管用,那倒是太好了!目前喷了大蒜叶,似乎还有绿虫子在上面,特别是那些长了花苞的玫瑰,虫子特喜欢 。前天把那些带黑斑的叶子都剪了,今天又看到有新的了,而且有的花苞都有斑点,很头大!
如果只是淀粉起作用的话,那就不应该是种番茄能防止玫瑰黑斑了,估计还是跟番茄有关,番茄的叶子是不太好闻,淀粉可能是起别的作用。就像有的建议滴点油什么的。我再观察几天,看看大蒜是否能完全请走这些小虫,实在不行,先把目前还没长大的番茄种在中间,等长大了再移走。那个英文说Spray: Liquify tomato leaves and then dilute them with 4-5 pints of water Add a tablespoon of cornstarch.
