英文摘要Nitrous oxide (N2O) emissions from N fertilizer applied to row crops makes up a large portion of the greenhouse gas loading to the atmosphere. Guayule (Parthenium argentatum A. Gray) is a desert perennial shrub being promoted for Central Arizona farmers as a source of natural rubber and hypoallergenic latex. Emissions of the greenhouse gas N2O and crop N uptake have not been previously quantified in this multi-year cropping system. A 2.5-year study was conducted on transplanted and surface-irrigated guayule on a Casa Grande sandy loam in Maricopa, AZ to assess the agronomic and environmental responses to N fertilizer application rate. Four N fertilizer rates ranging from 0 to 252 kg N ha-1 were applied as ammonium sulfate in three splits. Nitrous oxide emissions were measured with 1-L vented chambers 34 times over 98 weeks from 17 April 2013 to 6 March 2015 with pauses during winter dormant seasons. Nitrogen rate significantly affected N2O emissions, which ranged from 1.2 to 4.5 kg N ha-1 for the 0 and 252 kg N ha-1 fertilizer rates. Emission factors were 1.5, 1.4, and 1.3 % of the added ammonium sulfate-N emitted as N2O for 84, 168, and 250 kg N ha-1, respectively, which are in the range of those for other better-studied crops such as corn (Zea mays L.) and cotton (Gossypium hirsutum L.) Nitrogen uptake by guayule averaged 191 kg N ha-1 for biomass and rubber yields of 19 Mg ha-1 and 1070 kg ha-1, respectively. There was no effect of N rate on N uptake, biomass, or rubber yields because of initial soil profile nitrate (NO3) levels of 85-150 kg NO3-N ha-1. A N balance of inputs (initial soil NO3, N fertilizer, NO3-N added in irrigation) and outputs (N uptake, N2O, and dinitrogen (N2) emissions) was constructed. Unaccountedfor N was apparently lost as NO3 leaching below the root zone. In conclusion, the informative N2O emissions data presented are the first for guayule, and the N uptake levels reported here can be used in updated, improved N fertilizer recommendations for guayule.
