【摘要】 本试验测定了不同尿素处理的温室模拟箱内NO2和NH3浓度的变化特征,以及不同光、温条件对温室模拟箱内NO2和NH3浓度的影响。结果表明:箱内NO2和NH3的积累随尿素种类不同有明显差异,且与温度和光照有关:大棚内外NO2和NH3浓度差异显著,且与气象条件有关。盆栽辣椒成熟叶片褐色病斑伤害程度随两种气体浓度的升高而加剧。
【Abstract】 Summary Study on the concentration of NO2 and NH3 in the simulated greenhouse chest and effect of light strengrh and temperature on it in greenhouse and simulated chest with different types of urea was conducted by pot experiment. Results showed that the concentration of accumulated NO2 and NH3 varied with the types of urea in the simulated chest and it related significantly with the light strength and temperature. The concentration of NO2 and NH3 inside and outside the greenhouse were different significantly and it related to the weather. Brown spots on the maturing leaves of hot pepper aggravated with the increase of concentration of this two gases.
