以番茄品种中杂105为试材,研究了不同遮光率的新型白色遮阳网和传统黑色遮阳网覆盖对网室内温光环境、番茄幼苗生长指标及生理特性的影响。结果表明,随着遮阳网遮光率的降低,网室内光量子通量密度、气温、5厘米和10厘米地温均呈升高趋势。遮光率50%的黑色遮阳网和白色遮阳网的透射光谱明显不同,黑色遮阳网对紫外光的透光率较高,对可见光和红外光
The effects of new white shade net with different shading percentage and traditional black shade net covering on indoor temperature and light environment, growth index and physiological characteristics of tomato seedlings were studied with Zhongza 105, a tomato variety. The results showed that with the decrease of the shading rate of shading net, the light flux density, air temperature, 5 cm and 10 cm ground net temperature increased. The shading rate of 50% of black shading mesh and white shading is significantly different transmission spectrum, the black shade of UV light transmittance higher, visible and infrared light
