摘要
以陕西临潼石榴为研究对象,研究套袋方式(纸袋、膜袋)对石榴生长规律、石榴品质及安全性的影响.结果表明,套袋栽培技术能明显改善石榴果实的色泽及光滑度,减少裂果率,增加单果重量;套袋石榴果实中还原糖含量明显低于对照组(未套袋)石榴果实,而可滴定酸含量略高于对照组果实;套袋石榴果实中重金属(Pb、As、Hg)含量、农药残留量(氯氰聚酯)明显低于对照组(未套袋)石榴果实.石榴套袋栽培技术是生产优质石榴,提高石榴生产效益的重要措施.
The aim was to study the effect of bagging methods(paper bag and plastic bag) on the growth rhythm,fruit quality and safety of pomegranate from Lintong Shaanxi.The results showed that,bagging cultivation technique could improve color and luster of pomegranate greatly and reduce fruit cracking rate.Reducing sugar in bagging fruits was less than the controls(no bagging),but the contents of titratable acid were higher than the controls.The contents of heavy metals(Pb,As and Hg) and pesticide residue(cypermethrin) in bagging fruits were obviously lower than the controls(no bagging).Bagging cultivation technique was an important measure for producing high quality pomegranate and increasing productivity of pomegranate.
