摘要
为探究不同灌溉水量对沙棘品质的影响,在新疆生产建设兵团第九师170团进行大田试验.试验以当地主栽品种为研究对象,设置5个水分梯度.通过测定果实品质指标,结合主成分分析法探究灌溉水量对沙棘品质的影响,并且构建综合评价模型,从而筛选最优灌溉方案.结果表明:5个水分梯度下10项品质指标中,灌溉水量对沙棘维生素C影响显著;开花期、结果期增加灌水量显著提高了百果质量及果实纵横径;果实膨大期、果实成熟期适当减少灌水量并未对沙棘营养品质造成负面影响;随着灌水量的减小,总糖、维生素C及可溶性固形物增加,而总酸降低;主成分分析提取的3个主成分的累计贡献率达98.573%;综合评价模型计算得分表明,处理W3(灌溉定额450 mm)为最优水分处理.研究结果可为规模化种植沙棘提供参考依据.
In order to investigate the effects of different irrigation moisture content on the quality of sea buckthorn,field experiments were conducted at the 170th Regiment of the Ninth Division of the Xinjiang Production and Construction Corps.The study focused on the locally dominant variety,with five water gradients established.The fruit quality indexes were measured,and the principal component analysis method was applied to investigate the effect of different irrigation moisture on sea buckthorn quality,and a comprehensive evaluation model was constructed to select the optimal moisture treatment.The results show that among the 10 quality indexes under five moisture gradients,the effect of irrigation moisture has a significant effect on the vitamin C content of sea buckthorn.Increasing irrigation during the flowering and fruiting periods significantly improves the weight of a hundred fruits and the fruit′s longitudinal and transverse diameters.The appropriate reduction of irrigation moisture content during fruit expansion and fruit ripening does not negatively affect the nutritional quality of sea buckthorn.With the decrease in irrigation moisture,the total amount of sugar,vitamin C,and soluble solids increase,while the total acid content decreases.The cumulative contribution of the three principal components extracted from the principal component analysis reaches 98.573%.The calculated score from the comprehensive evaluation model indicates that treatment W3(irrigation quota 450 mm)is the optimal water treatment.The results of this study can provide a reference basis for the large-scale plan-ting of sea buckthorn.
