摘要
为了找到合适的光伏板密度,为葡光互补新型栽培模式的推广提供依据,设置葡光互补栽培钢架未安装光伏板(CK)、光伏板间隔1.5 m(C1)、光伏板间隔1.0 m(C2)、光伏板间隔0.5 m(C3)和传统小棚架葡萄园(NEA)共5个处理,测定葡光互补栽培模式和传统小棚架下无核白果实的外观品质和内在品质,并使用方差分析和主成分分析法比较各处理果实品质的差异。结果表明,与CK相比,无论是光伏板遮阴还是传统的低矮小棚架对无核白果实的外观品质均无显著影响,但显著降低了葡萄果实的可溶性固形物、果糖和葡萄糖含量。通过主成分分析发现,按照各处理的果实品质综合得分由高到低排序为:CK,C2,NEA,C3,C1。处理CK和C2的综合得分分别为75.88、75.16,分别排名第1位、第2位,明显高于NEA的综合得分(50.45),C3和C1处理的综合得分分别为47.86、45.30,与NEA综合得分相近。因此,在综合考量葡萄品质和光伏板发电效益的情况下,在吐鲁番地区宜选择光伏板间隔1.0 m的葡光互补栽培模式进行推广。
In order to find suitable density of photovoltaic panels,and to provide some bases for a new extending cultivation mode of grape-photovoltaic panel complementation,appearance quality and internal quality of Thompson Seedless Grape fruits were determined under grape-photovoltaic panels complementation cultivation model and small traditional trellis,and differences of fruit quality between each treatment were compared by variance analysis and principal component analysis.The five treatments were no photovoltaic panel on trellis(CK),photovoltaic panel spacing of 1.5 m(C1),photovoltaic panel spacing of 1.0 m(C2),photovoltaic panel spacing of 0.5 m(C3),and small traditional trellis(NEA),respectively.The results showed that compared with CK,both photovoltaic panel shading and small traditional trellis had no significant effects on appearance quality of Thompson Seedless Grape fruits,but significantly reduced contents of soluble solids,fructose and glucose in fruits.The results of principal component analysis showed that,the order of each treatment based on comprehensive scores of fruit quality from high to low was CK,C2,NEA,C3,C1.The comprehensive scores of CK and C2 treatments were 75.88 and 75.16,ranking the first and the second respectively,which were significantly higher than the comprehensive score(50.45)of NEA treatment.The comprehensive scores of C3 and C1 treatments were 47.86 and 45.30,which were similar to the comprehensive score of NEA treatment.Therefore,through comprehensively considering grape quality and photovoltaic panel power generation benefits,it was recommended to extend the cultivation model of grape-photovoltaic panels complementation with photovoltaic panel spacing of 1.0 m in Turpan.
