It is interior, the growth of plant is maintained by being colonized cotton absorption nutrient solution, (the general section's science and technology in Shenzhen is limited by LED plant growth lamp
Company) type of wavelength is abundant, just coincide with plant light synthesis and the spectral region of photomorphogenesis that it is photosynthetic to be effectively promoted
Effect improves plant growth rate, after 5-8 days, direct observation experiment phenomenon.
4. by the water suction line to connecting, penetrate in plant cultivation pipe, one section of rope is put into lucite pipe, and is added
Water, other end are placed on dry table top, by the mung bean after immersion be placed on to connect water suction line intermediate position, 5-8 days
Afterwards, direct observation experiment phenomenon, no matter according to which kind of modes of emplacement, as long as the moist degree of 2 ropes has notable difference, finally
The root of plant just will appear obviously hydrotropism, this experiment illustrates that the root of plant has the characteristic to water.
5. 2 water suction cotton ropes are penetrated in plant cultivation pipe, the mung bean impregnated is placed on water suction line, and pull water suction
Line, allows mung bean to be located at plant cultivation pipe middle, and water suction line both ends will be put into lucite pipe and add water, 5-8
After it, direct observation experiment phenomenon, no matter how we place plant cultivation pipe, at first, because plant cultivation pipe
It stops, root and stem can all be grown sidewards, but once be detached from the obstruction of plant cultivation pipe, and root is grown vertically downward at once, stem horse
On grow up, illustrate that plant has obvious to (back of the body) property.
6. fresh water pouring is to suitable position in lucite pipe, be then perfused edible oil, effect be by oil to water into
Row sealing eliminates the observation influence that the evaporator strip of the water surface itself comes, removes seal closure, epipremnum aureum branch is inserted into lucite pipe
It is interior, then tester is sealed with seal closure again, observes whether seal closure surface has water mist later within 30 minutes, is passing through oil seal
Afterwards, in the case of without plant, seal closure does not have water mist, and in the case of having plant, sealing is covered with water mist, and plant can be observed
Transpiration.
