What are the external conditions that affect the uptake of mineral elements by plant roots, and why?
With the ordinary lamp plant has obvious advantages over ordinary plant growth useless ultraviolet radiation lamp with infrared light on plants, waste a lot of energy, and LED growth light by using electro luminescent mechanism, in the same light intensity under the condition of LED growth light than plant growth lamp saving more than 80%.
The photoperiod sensitive plants, flowering (short day and long day plant) is mainly affected by the light duration or photoperiod, and not sensitive to photoperiod type plants (neutral) by light impact, photosynthesis is mainly affected by the amount of light and light intensity. Photosynthesis occurs mainly within the visible spectrum (400-700nm) in the LED region and the strongest photosynthesis plants grown in red light blue light according to the growth mechanism of plant photosynthesis by selective rotation of the LED light source, color mixing ratio of RB in accordance with the scientific, artificial plants 450-47 long required light, pure spectrum, spectrum in 0615-625.
Influence of light and light plant to plant in four forms: light, photoperiod, light intensity and light, plant growth and yield (plant size, flower number and other characteristics) is mainly affected by the light received within a day, plant morphology (height and plant type) and the main light (mainly, blue and red).
Light causes evaporation of water, which causes the roots to absorb moisture and absorb mineral elements.
