食蟲植物的根

http://www.bio.nsysu.edu.tw/seminar/sem_cont/B942010023-%E5%BE%90%E7%91%8B%E5%90%9B-%E9%A3%9F%E8%9F%B2%E6%A4%8D%E7%89%A9%E7%9A%84%E6%A0%B9.doc

E篇野可信性唔知高唔高,但都有D參考價值同值得討論o既地方....
其實好多人都冇用蒸餾水淋花.....但唔見得種得差

唔係任何一種食蟲植物都要用蒸餾水淋
不過有D就真係必需

請問係邊幾種?
我的捕蠅草大約有3年冇用蒸餾水淋....我的捕蠅草有花又有夾又食蜜蜂又冇變黑

所以我認為食蟲植物中捕蠅草是可以唔用蒸餾水淋
而文中亦有在第4 part一提到捕蠅草生於含鹽的酸性沼澤

請問你係邊到住?

都應該要考慮番水質

VII. High-nutrient conditions

Some CPs may reduce their growth and even die when grown in nutrient enriched soils (see Juniper et al., 1989, p. 134). Dionaea muscipula grew very poorly in a conventional clay-loam garden soil (Roberts and Oosting, 1958). The leathery leaves did not develop traps and flowering was greatly reduced. After 5 months, most plants were dead. Similarly, when grown in a fertilized greenhouse potting soil, roots of Dionaea were atrophied, no new roots formed, and plants died within 70 days. In another experiment, the growth of Dionaea in a sand culture with mineral nutrient solution was poor; plants declined in weight, and died after about 3 months, while the controls watered with distilled water grew much better. The insect- or protein-fed plants showed more vigorous growth than the controls. As follows Dionaea is very susceptible to higher soil nutrient level and its root growth is suppressed in heavier soils (cf. Adamec et al., 1992). Eleuterius and Jones (1969) studied the growth of Sarracenia alata in a southern Mississippi bog and found a growth decrease in fertilized bog soil (seasonal supply of 37.1 g N.m-2 and 5.9 g P.m-2; cf. Stewart and Nilsen, 1992; chapter VI.). Possible negative effects of nutrient-rich soils on the growth of Nepenthes were discussed by Juniper et al. (1989, p. 134).

咁鍾意睇文獻就睇D勁D既 review 啦 ~

慢慢睇 !

多謝行大篇文獻，但系我就真系睇唔到距點樣勁法，果d nutrient enriched soils 究竟有幾nutrient，完全無單位睇到，真系唔知點樣勁法。同吸烟會危害健康無咩分別，但系偏偏有d阿叔吃左幾十年煙都身體健康。D文獻裡面記載著1d實驗，但系你屋企我屋企其他人屋企唔系一樣都系做緊實驗咩？我3年來都系用水喉水種花，無錯，sydney d 水喉水軟過hk的，但系絕對唔系蒸餾水，同埋我3年黎好似未換過d植料，我仲系用7cm pot（save翻d泥啊嘛）。
唔知你仲記唔記得之前討論過Utricularia 系魚缸度種果個post？

Argon 你咁即係攞黎拗啫 ~ 有 detail 就叫勁, 冇分析含量就唔知點樣勁法 .. 你D definition 都幾無厘頭噃 ~

你用水喉水種花就叫做實驗 ?? 你咁叫撞彩 ~ 我所謂做實驗至低限度係用電導表度住做嘅 ~

你用水喉水種花唔死就代表可以叫全世界跟你用水喉水種呀 ?! 至多可以話 "用你果D水喉水" 種花唔死啫 ~

到而家你都唔明點解叫人用蒸餾水種花呀 ?? 冇人話唔用蒸餾水種花一定死, 現實產區D泥都有 minerals, 爭在多定少啫, 因為唔係人人都有導電度或者離子表, 咁唯有用最安全既方法囉, 用蒸餾水咪包冇死囉 ~

蒸餾水導電度係 0 μs/cm

仲睇唔到佢同你篇台灣論文比較點樣勁法 ?? 咪淨係 reference 都多幾廿頁紙囉 ~

大家都係以事論事
最重要唔好傷到大家和氣

其實呢個問題都冇咩好講,
我都記得睇書睇過礦物係對捕蠅草有害

Argon
呢個係香港的論壇,水質都係以香港的水質黎衡量
如果以香港的水喉水水質黎講
就唔係好適合捕蠅草喇

唔系2x盤都撞采啊嘛？
我唔系學者，唔識分篇journal勁唔勁。。。。
我只系覺得篇野有值得討論o既地方....

12# dryfish
我真系覺得有討論的空間，我的經驗再加埋我見到hk人用水喉水種的post，同埋篇0野，所以我先開post，想大家討論下。我亦都好尊重魚干兄同行大的意見，可能大家觀點角度唔同姐。無話傷唔傷氣的。

其實食蟲植物對水質的要求高,相信大家都知道.
需不需要用蒸餾水我覺得真的視乎地區和經驗,
以我的經驗,我使用水喉水一定不能,因為都失敗過好多次.但同樣在香港,我的朋友在沙田使用水喉水就完全沒有問題.
所以可以使用水喉水與否,每個人的經驗都不同而有選擇!!
當然以香港為例子,初種食蟲植物以蒸餾水是最安全的做法!
篇文我都未有空看,遲下看看先!!

4.        鹽分
　　捕蠅草生於含鹽的酸性沼澤（Juniper et al., 1989），露松也有可能生於這種環境（Harshberger, 1925）。另有四種豬籠草- N. albomarginata、N. reinwardtiana、N. treubiana、N. mirabilis（Juniper et al., 1989）生於東南亞海邊浪區，無競爭者。根據Speris（1981）豬籠草分布的研究顯示，豬籠草的祖先為白堊紀沿岸的鹽土植物（halophyte），由於海平面下降而移至內陸。

我唔系學者，唔識分篇野可信性唔知高唔高,但相信有D參考價值同值得討論o既地方....

Argon 你咪咁執著啦 ~ 好多 review 論文都係不求甚解亂抄, 與傳統背道而馳, 根本無乜討論的空間 ~

總之, 需唔需要用蒸餾水根本無需咩實驗或者經驗, 揾個表度下睇下過唔過 100 μs/cm 咪知用唔用得你水喉果D水囉 ~ 呢D先至叫科學吖嘛 ~ 唔係無標準講咩都冇用 ~ 明冇 ?!

感謝行大的意見,需要時間思索......
唔知你仲記唔記得之前討論過Utricularia 系魚缸度種果個post？

簡單講我認為食蟲植物適應香港水變港蟲用唔用蒸餾水淋都冇所謂

講講迷你毛同陸生狸
陸生狸生命力強頑，建議先用蒸餾水種，種定之後想佢死都幾難，用唔用蒸餾水種都冇所謂。
迷你毛因為個體單一同細小，環境唔適合有可能集體死亡，一日之間捐失慘重，建議用蒸餾水種。
