Effects of Different Artificial Light Sources on Mechanical Properties of Closed Stereoscopic Rice Seedlings

Abstract

 The effects of fluorescent lamp (TFL), LED fluorescent lamp (W), LED red light (R), LED blue light (B) and three different combinations of LED red light and LED blue light (R:B 3:1, R:B 5:1, R:B 7:1) on the mechanical properties of rice seedlings were studied. The results showed that the stem diameter of seedlings was positively correlated with the stem pulling force, the dry weight of 100 plants and the stem shearing force.and the growth strength order of the rice seedling under different light conditions was W > NL > TFL > RB > R > B.Appropriate artificial light source can improve the seedling quality.
