lawn service公司来兜售生意,说我门前草长得不好,有fungi,要处理,不然明年春天
就要全部重搞,thousands dollars。
当然我才不入他的圈套, 但是现在这个草确实是越长越稀,不知道怎么搞。
请教一下,是不是去Homedepot 找除fungi的药喷一下? 需要确定是哪一种fungi吗?
那人说杀了fungi之后要施肥(具体没听懂啥东西), 然后瘌痢头会自动长好。 是不
是就撒一些lawn fertilizer? 有没有针对瘌痢头的专门方子?

v**a 发帖数: 2062 | 23 刚才有人建议开专题讲采蘑菇。我来讲讲我在NJ采蘑菇的经验。
最开始采蘑菇是跟个俄国女同事学的。NJ各个park和山头走了不少,最后觉得蘑菇最多
的地方是cheesequake state park,从edison沿GSP十几分钟就到。到了秋天,特别下
雨后,此公园到处都是蘑菇。九月份是最好的时候,十月后天气转冷就没有蘑菇了,八
月也应该有,但是因为labor day以前进去要交钱,我没有在七八月去过。
初学采蘑菇可参照下面的网页。
http://mdc.mo.gov/nathis/mushrooms/mushroom/edible.htm
切记学会认清能吃死人的Amanitas的几个典型特征,其他的一般就算有毒也吃不死人。
可采蘑菇中最容易辩认也不会搞混的是Boletes和CORAL FUNGI(见所给连接图片和介绍
),我最开始只采这两种。
Boletes帽顶是棕色,帽底一般是黄色海绵状,有的会偏绿。不要摘帽底是橙色或红色
的。这种蘑菇最容易辨认,味道也极佳。初学才蘑菇者最好先从bolets开始。不过
bolets因为跟枯叶颜色相似,不容易一眼看出来。
coral fungi特征也极 |

If your camera happens to get infected with fungus, you need to act

protective coating; the fungi may even etch the glass and ruin the lens.
Luckily for us, this type of fungus is rare. There are few mixtures you can
