摘要:
通过研究不同硝酸铵施用量对金叶女贞生长和光合特性的影响，以期为科学合理施用氮肥提供理论依据。试验在城市环境条件下，于2020年和2021年设置硝酸铵施用量为0 g/株（T1，CK）、5 g/株（T2）、10 g/株（T3）、15 g/株（T4）处理4个，重复3次。结果表明：2020年、2021年7月，T3、T4株高显著高于对照和T2；2020年、2021年5—7月，T3与T4净光合速率显著高于对照，4—6月T2与对照之间无显著差异；2020年5月和7月，2021年4月和7月、T3和T4气孔导度显著高于对照和T2，T2与对照之间无显著差异；2020年、2021年5—7月，T3、T4胞间CO2浓度显著低于对照，蒸腾速率显著高于对照。不同硝酸铵处理对金叶女贞株高和光合特性的影响顺序为T4>T3>T2。
Abstract:
To provide scientific and rational basis for nitrogen fertilizer application in garden maintenance, we studied effects of different ammonium nitrate amount per plant on the growth and photosynthetic traits of Ligustrum×vicaryi. The test was carried out under urban environmental conditions, by setting 3 treatments and CK in ammonium nitrate application as 0 (T1, CK), 5 (T2), 10 (T3), 15 (T4) g per plant in both 2020 and 2021. The results showed that the plants with T3 and T4 were significantly higher than those of CK and with T2 in July, 2020 and 2021. And the net photosynthetic rates with T3 and T4 were significantly higher than that of CK from May to July, no significant difference between those with T2 and of CK from April to June. In May and July 2020, April and July 2021, the stomatal conductance with T3 and T4 was significantly higher than those with and T2 and of CK, no significant difference between those with T2 and of CK either. From May to July in both 2020 and 2021, the plants with T3 and T4 were characteristic of significantly lower intercellular CO2 concentration, yet higher transpiration rate than those of CK. It was concluded that the effects of different ammonium nitrate treatments on the height and photosynthetic traits of L. × vicaryi was presented in such order as T4>T3>T2.
