摘要
利用两间玻璃室内夜间不同的温度条件,研究了夜温升高对双季早晚稻秧苗素质的影响。结果表明,与夜间常温对照相比,夜温升高明显加快了早晚稻秧苗的出叶速率,提高干物质的积累量。但夜温升高降低晚稻秧苗的发根力,不利于秧苗的根系伸长。
By using the different nighttime temperature in two glass-houses, the experiments were conducted to study the effects of nighttime temperature increases on the seedling quality of double season rice. The results showed that： nighttime temperature increases can accelerate leaf appearance of rice seedlings obviously, and increase dry matter accumulation. But the root growth ability （the root number x average root length） and root length were decreased by nighttime temperature increases.
