来自主题: gardening版 - 新人问个Apple tree pollinator的问题
我们在南加,刚种了一棵Anna apple tree,意识到Apple tree最好有cross-
pollinator,
问nursery owner,他们有Dorsset Golden, which is supposed to be a good
pollinator for Anna.
但owner建议Anna 不一定需要polination如果我们只想种一棵苹果树,如果想种点别的,
可以考虑Santa Rosa plum,因为它也可以给anna当cross-pollinator. 可我后来上网
查,
没有人说apple可以用plum来传粉的。有懂的可以给讲讲吗?

last week, I pollinated cantaloupe flowers. But only two out of 10 keeps
growing. I don't know why I did it wronly.
I just cut the male flower and pasted it inside the female flower, and used
tape to wrapper it.
What is your good way to pollinate the cantaloupe flowers?
Thanks.

I'm so happy! :-) I planted the tree in spring 2010, and now have two
persimmons. :-D
My friend told me that persimmon tree require cross-pollination. I only have
one persimmon tree.
I guess mine tree doesn't require cross-pollination, or I'm so lucky!

What To Know Before You Grow Fruit
In gardening, fruit trees yield an excellent return on investment. A semi-
dwarf apple tree with a harvest life of 15 to 20 years can yield up to 500
apples per growing season. If you average production costs for homegrown
apples over 10 years, the apples cost roughly a penny apiece – a definite
discount over organic store-bought apples. Plant different fruit trees with

The flowers are hermaphroditic and have a mechanism to avoid self-

later, male stage in a matter of hours. This requires a separate pollinator
that not only can collect the pollen from flowers in the male stage, but
also deposit it in flowers in the female stage.

It is pouring now. No bees. So I have to take an umbrella to go out to

Although I used the same protocol for the pollination today, I noticed some
difference for the stigma and stamen. For example, it is difficult for us to

if the stamen has successfully fallen onto the stigma.

Pollinating seems a easy job, but is actually exhausting.
You need to climb up sometimes, or kneel down sometimes.
Some stamen in male flower are small, so you need to tape them inside
the stigma of a female flower.
Most boring part is their leaves make you allergical.
The pollen can make you allergical too.

of course.
Tomato flowers are stigma and stamen existing at the same flower.
So it doesn't need bees, but strong wind for pollination in natural
environment.
I use my electric brushtooth for pollinating tomato flowers.
It works great!
My method works for pepper too.

这个吗?
If your zucchini blooms flowers but never bears actual zucchini, or it bears
fruit that stops growing when it's very small, then it's a pollination
issue. Most squashes have separate male and female flowers on the same plant
. To produce fruit, pollen from male flowers must be physically transferred
to the female flowers by bees. If you do not have enough bees, you can
manually pollinate with a Q-tip—or, add nearby plants that attract bees!
