摘要
【目的】研究猕猴桃/生姜间作对生姜光合特性及产量的影响,为猕猴桃/生姜间作模式的应用提供科学依据。【方法】以生姜品种长姜1号为研究对象,设置遮阴生姜单作(CK)、未遮阴生姜单作(US)和猕猴桃/生姜间作(KG)3种栽培模式,比较各栽培模式对生姜光照强度、叶绿素含量、光合参数、抗氧化系统、形态指标和产量的影响。【结果】与CK模式相比,KG模式下生姜的叶片光照强度、叶绿素含量、光合参数(除蒸腾速率)、过氧化氢酶活性、1,5-二磷酸羧化酶活性、丙二醛含量和形态特征(除根茎纵长)均无显著差异。与US模式相比,KG模式下生姜叶片的光照强度显著降低58.36%,叶绿素a、叶绿素b和总叶绿素含量显著提高;净光合速率和蒸腾速率显著升高,气孔导度和胞间CO_(2)浓度显著降低;过氧化物酶和超氧化物歧化酶活性以及可溶性蛋白含量显著提高,丙二醛含量显著降低;生姜株高、茎粗、叶片数、地下部形态指标(除姜球直径)和产量均显著提高。【结论】猕猴桃/生姜间作能够有效降低光照强度,提高生姜的叶绿素含量、光合参数和抗氧化酶活性,促进生姜生长并提高产量,具有良好的应用潜力和推广价值。
[Purpose]To study the effects of kiwifruit/ginger intercropping on photosynthetic characteristics and yield of ginger,providing scientific evidence for the application of this intercropping model.[Methods]Ginger variety‘Changjiang No.1’was used as research object,and three cultivation patterns were set up:shaded ginger monoculture(CK),unshaded ginger monoculture(US),and kiwifruit/ginger intercropping(KG).The effects of these three cultivation patterns on the illumination intensity,chlorophyll content,photosynthetic parameters,antioxidant system,morphological indicators,and yield of ginger were compared.[Results]Compared with CK,there was no significant difference in illumination intensity,chlorophyll content,photosynthetic parameters(except transpiration rate),catalase activity,1,5-diphosphocarboxylase activity,malondialdehyde(MDA)content and morphological characteristics(except longitudinal length of rhizome)of ginger under the KG.Compared with US,the KG significantly reduced the illumination intensity by 58.36%,while the chlorophyll a,chlorophyll b,and total chlorophyll contents significantly increased;net photosynthetic rate and transpiration rate increased significantly,while stomatal conductance and intercellular CO_(2) concentration decreased significantly;the activities of peroxidase and superoxide dismutase,and soluble protein content increased significantly,but MDA content decreased significantly;plant height,stem diameter,leaf number,morphological characteristics of underground parts(except diameter of ginger ball),and yield of ginger significantly increased.[Conclusion]Kiwifruit/ginger intercropping can effectively reduce illumination intensity,increase ginger chlorophyll content,photosynthetic parameters,and antioxidant enzyme activity,promote ginger growth,and increase yield.Therefore,this intercropping pattern has excellent application potential and promotion value.
