摘要： Ammonia (NH3) is one of the important greenhouse gases which could affect the climate change, to reduce the number of farmland ecosystem of NH3 emissions, using the intermittent airtight ventilation method, studied the impact of rotation and long-term plant crude opium cultivation conditions above emission regularity of NH3 volatilization and dynamic growth. The results show that compared with the crop rotation treatment, continuous cropping treatment can significantly increase the emissions of NH3 volatilization rate and vega cumulants, stage and basal fertilizer than vega emissions of NH3 volatilization rate is high, the soil is 0.46 kg. hm(-2). d(-1); In stage basic fertilizer and fertilizer, continuous cropping treatment and rotation of NH3 volatilization cumulants are in line with the Logistic growth curve, and the measured values and calculated a highly positive correlation between simulation value; Throughout the vega fertilizing period, continuous cropping treatment of NH3 volatilization cumulant than 0.055 kg/hm(2), rotation and continuous cropping treatment and rotation NH3 volatilization loss rate of 1.58 times. Crop rotation system can reduce the NH3 volatilization rate, and can reduce the NH(3)volatilization cumulative loss, and thus can reduce the NH3 volatilization loss rate.
