穹顶棚架栽培对杨梅果实品质的影响

Effect of Cultivation with Dome Pergola on Fruit Quality of Myrica rubra

研究杨梅穹顶棚架栽培模式对果实品质的影响,拟解决杨梅成熟期常遇雨水和果蝇为害致使果实品质下降的问题。以‘东魁’杨梅为试验材料,于2016年在浙江青田开展杨梅穹顶棚架栽培试验,对采收期果实的理化指标进行测定分析。结果表明,与露地栽培相比,穹顶棚架栽培模式下杨梅果实单果重、果实硬度、可溶性固形物、总糖、Vc含量及甜度分别提高10.3%、19.2%、10.5%、17.6%、20.3%和17.8%,同时,可滴定酸含量减少24.5%,虫果率降低92.0%。杨梅采用穹顶棚架栽培模式可以达到避雨防虫的效果,进而提升果实品质,有效促进杨梅绿色高效生产。

The paper aims to study the influence of Myrica rubra dome pergola cultivation mode on fruit quality,and to solve the problem of fruit quality degradation caused by rain and drosophila in the mature stage of M.rubra,so as to lay a foundation for the sustainable and healthy development of M.rubra industry.Using‘Dongkui’M.rubra as the test material,the dome pergola cultivation test of M.rubra was carried out in Qingtian,Zhejiang Province in 2016,and the physical and chemical indexes of fruit during harvest period were measured and compared.Compared with open field cultivation,the single fruit weight,fruit firmness,soluble solids,total sugar,Vc content and sweetness of M.rubra under dome pergola cultivation mode were increased by 10.3%,19.2%,10.5%,17.6%,20.3%and 17.8%respectively.Meanwhile,the titratable acid content was decreased by 24.5%and the worm fruit rate was reduced by 92.0%.The dome pergola cultivation mode of M.rubra could achieve the effect of a shelter from rain and preventing insects,thus improving the fruit quality and effectively promoting the green and efficient production of M.rubra.
