大戟種子的採收法 My Euphorbia harvest method

這是我今年實驗的新方法：用紙膠帶
不知道為甚麼，紙膠帶的黏膠不會在高溫下分解
其他種類的膠帶放在溫室裡都會融掉

徒手撕下紙膠帶後，寫上住記，我的母本群都有流水號。用對折的方法把整朵花都黏起來。這樣同時可以做到住記交配式，避免昆蟲跑來亂受粉，以及包住亂射的種子。

大戟果實在爆開前就已經熟了，同一根花序上的一批果實會同時間成熟，只要其中一個爆開就能全收了。


I try this new method this year: using paper tape
I don't know why,but the glue in  paper tape will not decompose at high temperature.
Other types of tape will melted or decompose in the greenhouse.

After tearing off the paper tape by hand, write on the memory, my propagation plant all have a serial number. Folding the tape together to inclose the whole flower.
This method can make note in-situ , avoiding the insects running around, and capture exploding seed.


The Euphorbia fruit is already macture before it bursts, and a batch of fruit on the same inflorescence will mature at the same time. When one of them bursts open. Wole batch on same inflorescence can be harvest.

嫁接搶救塊根鳳仙 Impatiens tuberosa graft rescue

Impatiens tuberosa  還算好種，在亞熱帶的台灣，實生半年就能養到開花，塊根可以衝到4CM
但是他卻很容易莫名其妙根腐暴斃。
我嘗試腰水栽培，得到一個月0.5CM的極高生長速度，但是卻在九月初時爛掉了。

我的朋友很好心的在12月又送了我一株。
我二度挑戰後，這次改用較乾燥的介質，還是爛了。推測是我換盆後有傷口就澆水。
總之，他在悶濕環境下容易莫名其妙暴斃。
讓我有種擬蹄玉和石頭玉的感覺。


第二株腐爛時還在初期，塊根沒爛完。因此我能保留一部分塊根，嫁接時面積較大。
成功了。


我用花市買來的鳳仙花當台木嫁接。

嫁接後用石蠟膜膠帶封住，輕輕的纏繞包裹多次是訣竅。用手壓，讓石蠟膜彼此黏起來變成硬殼狀。

放在室內陽光散射的窗台，溫度有25~28C

第一次嫁接後，我把整株連盆放入悶箱。結果因為水分太充足，吸太多水後傷口爆開。
才過2天而已，我馬上就觀察到了，然後重接。

這次把他放在窗台上，成功了。
你可以明顯看到他生長，甚至還沒到生長季咧。

Impatiens tuberosa is't very hard so to speak . In the subtropical Taiwan, it can be flowered in half a year from seed, and the caudex can be pump up to 4CM.

But he is shockingly prone to root rot.
I tried to cultivate in the water tray and got a very high growth rate of 0.5CM per month, but it rotted at the beginning of September.

My friend kindly give me another seedling in December
In  my second attempt , this time I switched to a drier medium, it still rotten.
I speculated that i water too soon after rept,the wound touch the water and rot.

In short, he is inexplicably prone to sudden rot in a humid environment.
Remind me of Pseudolithos and lithops.


In the second case,the root rot is still in its early stages.A large chunk of caudex still remain. Therefore, I can retain a part of the caudex, which give me  larger touching area when grafted.

Success.

I used the balsam flower bought from the local flower market as stuck.

After grafting, it is sealed with parafilm tape. Gently press with  hand to make the parafilms stick to each other and become a hard shell.

Placed on the window sill of indoor sunlight scattering, the temperature is 25~28C

The first try, I put the whole plant into the humid box. As a result, because the water is too abundant, the wound bursts after sucking too much water.

It took only 2 days, I immediately observed it,cut and regraft.
This time he was placed on the window sill and succeeded.
You can clearly see the growth.It's not even growing season yet.
