以同鹽度的海水與食鹽水培養綠豆實驗結果：1. 綠豆在海水與食鹽水中的生

以同鹽度的海水與食鹽水培養綠豆實驗結果：1. 綠豆在海水與食鹽水中的生長趨勢一致，濃度愈高，綠豆生長受抑制的情形愈明顯。本實驗目的在探討土壤鹽化對植物生長的影響。因此，我們在前實驗中先嘗試以綠豆為探討對象，初步看到綠豆在食鹽水中生長會受到抑制在綠豆生長實驗中，低濃度的鹽水對綠豆的生長影響不大，但當鹽水濃度超過 0.4％時，綠豆的根、莖生長皆開始受到明顯的抑制，而且濃度越高，生長的抑制越明顯。所以我們找到重量百分濃度 0.5％的食鹽水，作為抗鹽分實驗的關鍵濃度。們在比較相同鹽度的海水和食鹽水實驗中，發現綠豆在海水中生長較食鹽水好。這可能是因為海水是混合物，混雜較多的離子，因此讓我們想到可以探討各種離子溶液對綠豆生長的影響。為了排除不同滲透壓的干擾，所以相關實驗改以相同的體積莫耳濃度為比較標準。我們查閱相關資料，知道任何植物如果長久生長在某一單一無機鹽溶液中，其根部細胞的細胞膜的通透性容易受到毒害，最後導致死亡，這種溶液只含有一種金屬離子而對於植物引起毒害作用的現象，成為“單鹽毒害”。我們的實驗中，綠豆在超過 0.5％食鹽水的關鍵濃度以上無法生長，這便是 NaCl 造成的“單鹽毒害”。而根據我們收集的資料，我們知道在能引起毒害作用的溶液中加入另一種礦質離子，植物將減弱對於原有金屬離子的吸收，其對植物的毒害作用即能減弱或消失，這種不同離子間、能互相消除毒害的現象成為“離子拮抗”作用。

Cultivating green beans with water and brine salinity
results:
consistent trend in growth of mung bean 1. seawater and salt water, the higher the concentration, the case of mung bean growth inhibition of more obvious.
Purpose of this study to explore the effects of soil salinity on plant growth. So, let's try to mung bean as in the previous experiment
to explore objects, preliminary green beans in salt water to see the growth will be inhibited
in growth of mung bean experiment, the low concentration of salt has little effect on the growth of green beans, but when the salt concentration exceeds 0.4 %, the
root of the mung bean, are stem growth began to be significantly inhibited, and the higher the concentration, the more significant inhibition of growth.
Therefore, we find the weight percent concentration of 0.5% saline as the salt concentration of the key points of the experiment.
Are the same in comparing the salinity of sea water and salt water experiments, we found good green beans grow more salt water in the sea.
This may be because the water is a mixture, mix more ions, so we want
to explore the possible effects of various ions in the solution of the growth of mung bean. In order to exclude interference of different osmotic pressure, so the relevant real
experiment a volume change at the same molar concentration as comparison standard.

We have access to relevant information, to know if the long-term growth of any plant in a single inorganic salt solution, the root cell
membrane permeability vulnerable to poisoning, leading to death, this solution contains only one metal ion and for the
cause of plant poisoning the role of the phenomenon as the "salt toxicity." Our experiments, green beans more than 0.5% sodium chloride
can not grow above the water critical concentration of NaCl which is caused by the "salt toxicity." The root
according to the information we collect, we know that the addition of another mineral ions in solution can cause toxic effects in plants will be
reduced to the original metal ion absorption of its toxic effects on plants that can weaken or disappear, this difference ion
between, can eliminate the poison of another phenomenon became "ion antagonistic" effect.

Mung bean culture with seawater and salt water of the same salinity
Experimental results:
One The growth trend of mung bean in seawater and salt water is the same. The higher the concentration is, the more obvious the growth of mung bean is inhibited.
The purpose of this experiment is to explore the effect of Soil Salinization on plant growth. Therefore, we try to use mung bean as the first experiment
The growth of mung bean in salt water will be inhibited
In the experiment of mung bean growth, low concentration of salt water had little effect on the growth of mung bean,
The root and stem growth of mung bean began to be significantly inhibited, and the higher the concentration, the more obvious the growth inhibition.
So we found 0.5% salt water as the key concentration of salt resistance experiment.
We found that mung bean grows better in seawater than in saline water in the experiment of comparing seawater and salt water with the same salinity.
This may be because the sea water is a mixture of more ions, so let's think
In order to eliminate the interference of different osmolality, we can discuss the effect of various ionic solutions on the growth of mung bean
In the test, the concentration of moles in the same volume was taken as the comparison standard.
We look up relevant data and know that if any plant grows in a single inorganic salt solution for a long time, its root cells
The permeability of the cell membrane is susceptible to toxicity, leading to death. This solution contains only one metal ion
In our experiment, mung bean is more than 0.5% of salt
The key concentration of water can not grow, which is the "single salt toxicity" caused by NaCl
According to the data we collected, we know that the plant will
If the absorption of original metal ions is weakened, the toxic effect on plants will be weakened or disappeared
The phenomenon of elimination of poison between and can be called "ion antagonism".
