套袋对茄子果实农药残留量及产量和品质的影响

Effect of Bagging on Fruit Pesticide Residues Yield and Quality in Eggplant

以京茄20为试材,研究了套袋对茄子农药残留、产量和品质的影响。结果表明:套袋可以显著降低茄子的农药残留,提高茄子的产量,改善茄子的光洁度等外观品质;套袋处理极显著降低茄子的硬度和纤维素含量;套袋处理茄子果实的坐果率、商品率、含水量、可溶性糖、Vc、蛋白质和维生素P含量处理和对照之间差异不显著;不同袋子对花青素含量的影响不同,套紫色聚乙烯塑料薄膜袋的茄子花青素含量与对照无显著差异,其它处理花青素的含量显著低于对照。因此,应选用紫色聚乙烯塑料薄膜作为茄子套袋材料。

Using eggplant（Solanum melongena L.）＇JingQie20＇ as test material,this paper studied the effects for pesticide residues,yield and quality of eggplant by using bagging.The results showed that：Bagging can significantly reduce the pesticide residue,increase production and improve the exterior quality such as the appearance of eggplant;bagging can also markedly reduce the hardness and cellulose content of eggplant;bagged fruit doesn＇t had significant difference from the one without bagging in data,such as the percentage of fertile fruit,commodity rate,moisture content,soluble sugar,vitamin C,protein and vitamin P content.The results also showed that different colors of the bags affect the anthocyanin content of eggplant.The eggplant with purple polyethylene plastic film had similar anthocyanin content with the one without bagging,while others had remarkably lower content.Consequently,the purple polyethylene plastic film was proposed to be used as bagging material for eggplant.
