Outcome record is at the bottom of April December to next year in the table, and minute is contained winter and spring, promptly under the low situation of temperature, observe easily since the heat that rhizosphere illumination produces to the influence of water temperature.The result shows, the water temperature of various processing is more stable, do not take place to cause that because of the light action of various light emitting diodes tangible water temperature changes, the water temperature that the light that wherein has is handled is contrast rising 0.5 ~ 1.0 degree, but low 0.5 ~ 2.0 degree of the contrast that also has, and this temperature high or low be not to be constant at certain light to handle in process of growth, but irregularly handle no correlation with LED light, and what the analysis reason may be with temperature in the winter greenhouse is inhomogeneous relevant.
Though the rhizosphere water temperature has such minor variations, luffing does not all exceed the temperature range of plant normal growth needs, changes the comparativity that does not influence processing.So can conclude, light emitting diode is tested as the illumination that light source can be used in the root system environment.
The illumination of tomato rhizosphere is to the influence of growth
As known from Table 2:
(1) at night in the test of LED according to root system and day on daytime illumination overground part (A), have only the white and LED-blue streak of LED-to handle and produced positive result, with contrast ratio, two plant heights of handling are low, and total dry weight LED-is white high by 39%, and the LED-orchid is high by 17%.The long dry weight of its every 10cm stem increases obviously, and LED-increases by 54% in vain, and LED-is blue to increase by 31%.Opposite two hat/roots of handling reduce than all, and LED-descends 2.6 in vain, and LED-is blue to descend 1.5, show that both root growths contrast good.LED is according to root by day, day illumination overground part, promptly in the test with two irradiations (B) in the time, it is short that the white and LED-orchid of LED-etc. is all compared the height of photograph, both total dry weights are compared respectively according to high 49% and 86%, both long dry weights of every 10cm stem are compared respectively according to improving 50% and 1 times, and their hat/root illustrates that than comparing respectively according to reducing 2.4 and 1.6 the two overground part well-growns of handling well are consistent with its root growth.So the trend as a result of test (B) is same as test (A).
(2) effect that daytime, LED shone root (B) is than shining the effective of (A) evening, and in the test of LED according to root (B), except that the red injury of LED-, all the other are handled and all are better than contrast, show that tomato root does not have obvious selectivity to various LED light by day.
But need to prove that test (A) water circulation in evening has only 3 times, it is many to can not show a candle to test (B), and this reason may influence the effect of various LED light in the test (A).But this test evening, white and LED-orchid can cause that also the result of dry matter increase is very important according to LED-.
Test obtains PRELIMINARY RESULTS, keeping under the environmental condition such as normal illumination, with the root of light emitting diode (LED) as light source irradiation tomato, except that the root well-grown, the raising of overground part dry matter, demonstrates the efficient assimilation of plant.
The illumination of table 2 tomato rhizosphere is to the influence of growth
