摘　　要：为探究生物炭和稀土肥添加对蜜柚生理特性的影响,以四种施肥措施(常规化肥+生物炭+稀土肥、常规化肥+生物肥、常规化肥+稀土肥和常规化肥)在相同条件下培养蜜柚苗木。培养结束后测定蜜柚超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)、丙二醛(MDA)、游离脯氨酸(Pro)、相对电导率(REC)、叶绿素A(ChlA)、叶绿素B(ChlB)和叶绿素总量(Chl)。结果表明,生物炭与稀土肥的添加可显著提高蜜柚的生物量,降低蜜柚SOD、POD和CAT的含量,促进蜜柚光合作用的进行,提高蜜柚叶绿素含量。Seedlings of honey pomelo were cultivated under identical conditions by the application of four different fertilization treatments including the conventional fertilizer+biochar+rare earth fertilizer,conventional fertilizer+biofertilizer,conventional fertilizer+rare earth fertilizer,and conventional fertilizer alone so as to investigate the effects of biochar and rare earth fertilizer additions on the physiological characteristics of honey pomelo.Upon completion of cultivation,it was measured in honey pomelo the superoxide dismutase(SOD),peroxidase(POD),catalase(CAT),malondialdehyde(MDA),free proline(Pro),relative electrical conductivity(REC),chlorophyll A(ChlA),chlorophyll B(ChlB)and total chlorophyll(Chl).The results showed that the addition of biochar and rare earth fertilizer could significantly enhance the biomass of honey pomelo,reduce the content of SOD,POD,and CAT,promote photosynthesis,and elevate chlorophyll content in pomelo leaves.
