摘　　要：为解决油茶采摘费时费力的问题,以15个湖北省主栽油茶品种为研究对象,选取12个与轻简化栽培相关的性状为评价指标(单果鲜重、干果出籽率、干籽出仁率、种仁含油率、枝叶密度、树形指数、单株产量、病害级别、旱害级别、冠外果实比例、红色果实比例、采摘效率),采用DTOPSIS分析法,对15个湖北省主栽品种进行轻简化栽培适宜性的分析评价。品种的轻简化栽培适宜性评价值由高到低依次为‘长林53号’(C>0.6),‘长林3号’、‘长林40号’、‘长林4号’(0.5<C<0.6),‘华硕’、‘华鑫’、‘华金’(0.4<C<0.5),‘长林23号’、‘鄂油102号’、‘鄂油63号’、‘长林18号’、‘鄂油465号’、‘鄂油81号’、‘鄂油151号’、‘鄂油54号’(C<0.4)。采用欧式距离对DTOPSIS评价值进行系统聚类,当类间距离为15时,可将15个品种聚为3类,即3个轻简化栽培适宜性档次,前2个档次有‘长林53号’、‘长林3号’、‘长林40号’、‘长林4号’、‘华硕’、‘华鑫’和‘华金’。此评价结果基本符合湖北省油茶栽植现状,亦可为后续油茶造林及品种选育提供参考。The paper aims to solve the problem of time-consuming and laborious picking of Camellia oleifera.In this paper,15 main C.oleifera varieties in Hubei Province were selected as the research objects,and 12 characters(fresh weight per fruit,dried fruit seed yield,dry seed kernel rate,seed kernel oil content,density of branches and leaves,tree shape index,average fruit yield per plant,average disease level,average drought damage level,proportion of the fruit outside of crown,proportion of red fruit,picking efficiency)were selected which related to light and simplified cultivation as evaluation indexes.DTOPSIS analysis method was used to evaluate the suitability for light and simplified cultivation of 15 main C.oleifera varieties in Hubei Province.The evaluation values of the light and simplified cultivation suitability of the varieties were in descending order:‘Changlin 53’(C>0.6);‘Changlin 3’,‘Changlin 40’,‘Changlin 4’(0.5<C<0.6);‘Huashuo’,‘Huaxin’,‘Huajin’(0.4<C<0.5);‘Changlin 23’,‘Eyou 102’,‘Eyou 63’,‘Changlin 18’,‘Eyou 465’,‘Eyou 81’,‘Eyou 151’,‘Eyou 54’(C<0.4).Euclidean distance was used to systematically cluster the DTOPSIS evaluation values.When the inter-class distance was 15,15 varieties could be clustered into 3 categories,that were the 3 light and simplified cultivation suitability grades.The first 2 grades included‘Changlin 53’,‘Changlin 3’,‘Changlin 40’,‘Changlin 4’,‘Huashuo’,‘Huaxin’and‘Huajin’.The evaluation results are basically in line with the planting status of C.oleifera in Hubei Province,and can also provide reference for subsequent afforestation and variety breeding of C.oleifera.
