摘　　要： 以‘L402’番茄为试材,研究了不同材质果袋内微环境变化规律及其对果实膨大与品质的影响.结果表明:套袋可改变番茄果实发育的微环境,促进果实发育,使果实提早成熟,增加单果质量.硫酸纸袋内光照、湿度介于塑料袋与无纺布袋之间,除上午温度低于塑料袋外,下午及夜间的温度均较高,其收获时单果质量较对照增加了15.34%.但套袋果实的可溶性固形物、可溶性糖、维生素C含量和糖酸比值均低于对照,说明套袋影响了果实营养品质,降低了果实风味.由于套袋阻隔了果实与农药的直接接触,除无纺布袋内果实毒死蜱含量高于对照外,硫酸纸袋及塑料袋处理的番茄果实毒死蜱残留量及高效氯氰菊酯残留量均显著低于对照. Taking overwintering tomato variety ＂L402＂ as test material, this paper studied the effects of bagging with different texture bags on its fruit enlarging and quality, and the microenvironment within the bags. The results showed that bagging could change the microenvironment of fruit development, promote fruit maturing in advance, and improve fruit mass and quality. The light intensity and humidity in parchment bag were at the intermediate of those in plastic and no-spinning cloth bags, and the temperature was the highest among all treatments, except that it was lower than that in plastic bag at forenoon. The fruit enlarging rate in parchment bag was also the highest, and the single fruit mass increased by 15.34%, compared with the control. However, the fruit soluble solid, soluble sugar, and vitamine C contents and the sugar/acid ratio in all bagging treatments were lower than those of the control, suggesting that bagging debased the nutritive quality and the tastiness of tomato fruit. Due to the fact that bagging prevented the direct contact of fruit with pesticides, the fruit chlorpyrifos and betacypermethrin contents in parchment and plastic bags were lower than the control, except that the chlorpyrifos content in no-spinning cloth bag was higher.
