摘要
为探究砧木对短枝富士“成纪1号”长势、光合作用、果实品质和产量的综合影响,筛选出“成纪1号”在甘肃陇东地区不同水分条件下的适宜砧木,以正常供水和自然降水两种水分条件下,密植(行株距3.5 m×1 m)立架栽培的不同砧木[M9-T337(矮化自根砧)、新疆野苹果(乔化自根砧)、M26(矮化中间砧,基砧为新疆野苹果)]“成纪1号”嫁接树为试材,测定与树体生长、枝类组成、叶片光合特性、果实品质及产量有关的多项指标,采用模糊隶属函数法进行综合评价。结果表明,综合评价得分由高到低排序为正常供水+M9-T337(0.932)>正常供水+新疆野苹果(0.754)>自然降水+新疆野苹果(0.638)>正常供水+M26(0.521)>自然降水+M9-T337(0.258)>自然降水+M26(0.043)。陇东地区有灌溉条件的川塬区宜推广M9-T337砧,而依靠自然降水的山旱地果园宜推广新疆野苹果砧。
To investigate the comprehensive effects of rootstocks on the growth,photosynthesis,fruit quality,and yield of the short-branch Fuji apple cultivar Chengji No.1 and screen suitable rootstocks for Chengji No.1 under different water conditions in Longdong region of Gansu Province,Chengji No.1 grafted on different rootstocks,including M9-t337(dwarfing self-rooted stock),Malus sieversii(vigorous self-rooted stock),and M26(dwarfing interstock with M,sieversii as the base rootstock)were used as test materials to determine the multiple indicators related to tree growth,shoot composition,leaf photosynthetic characteristics,fruit quality,and yield under two water regimes,normal irrigation and natural precipitation,using a high-density trellis cultivation system(row spacing:3.5 m×1 m),and a comprehensive evaluation was conducted using the fuzzy membership function method.The results showed that the comprehensive evaluation score of each treatment was ranked as follow:normal irrigation+M9-T337(0.932)>normal irrigation+M.sieversii(0.754)>natural precipitation+M.sieversii(0.638)normal irrigation+M26(0.521)>natural precipitation+M9-T337(0.258)>natural precipitation+M26(0.043).In Longdong,for plain and plateau areas with irrigation condition,M9-T337 is recommended as the preferred rootstock,while M.sieversii is more suitable for rain-fed orchards in mountainous and arid areas.
