摘　　要：为了评估在城市绿地上种植本土植物的园艺方法,比较了扦插法、移植法、播种法、嫁接法、压条法对月季成活率、生长速率、叶片光合速率、叶绿素含量、比叶质量及叶片酶活性等关键指标的影响.嫁接法在成活率方面表现最为突出(86.33%),显著高于其他处理方法.移植法的成活率也较高(83.23%).嫁接法在60 d的生长周期内月季株高和茎粗均最高,生长速度在不同阶段均保持稳定.叶片光合速率的测定进一步证明嫁接法在提高光合作用效率方面具有优势,其光合速率最高,且叶片内部二氧化碳浓度较低,气孔导度较高,有利于水分管理.嫁接法处理组在叶绿素a、叶绿素b和类胡萝卜素含量上均表现优异,叶绿素a/b比值也相对较高.嫁接法在增强月季抗氧化防御能力方面效果明显,其过氧化氢酶、超氧化物歧化酶和过氧化物酶活性均显著高于其他处理组.综合分析表明,嫁接法在提高月季成活率、生长速率、光合效率、叶绿素含量、水分管理和抗氧化能力方面均表现出显著优势.In order to evaluate the horticultural methods of planting native plants in urban green space,this study compared the effects of cutting,transplantation,sowing,grafting and layering methods on the survival rate,growth rate,leaf photosynthetic rate,chlorophyll content,specific leaf weight and leaf enzyme activity of Chinese rose.The results showed that the grafting method was the most prominent in terms of survival rate,reaching 86.33%,which was significantly higher than other treatment methods.The survival rate of transplantation method was also higher,which was 83.23%.The grafting method had the highest plant height and stem diameter in the 60-day growth cycle,and the growth rate remained stable at different stages.The determination of leaf photosynthetic rate further showed that the grafting method had the advantage of improving photosynthetic efficiency.The photosynthetic rate was the highest,and the carbon dioxide concentration in the leaves was low,and the stomatal conductance was high,which was beneficial to water management.The grafting method treatment group showed excellent performance in chlorophyll a,chlorophyll b and carotenoid content,and the chlorophyll a/b ratio was also relatively high,which may be related to the improvement of light energy utilization efficiency of plants.The effect of grafting method on enhancing the antioxidant defense system of rose,and the activities of catalase,superoxide dismutase and peroxidase were significantly higher than those of other treatment groups.The comprehensive analysis showed that the grafting method showed significant advantages in improving the survival rate,growth rate,photosynthetic efficiency,chlorophyll content,water management and antioxidant capacity of rose.
