摘要 果袋材質(zhì)不同,對葡萄成熟期及品質(zhì)的效應(yīng)不同。該研究針對鄞紅葡萄套外黃內(nèi)黑復(fù)合果袋能有效延長成熟采收期、避免高溫和日灼,但存在著色差、糖度低等問題,探討了成熟前不同套袋及摘袋時間對果實各品質(zhì)性狀的影響。結(jié)果表明:提前2周摘復(fù)合果袋套白袋不僅能有效延遲葡萄成熟采收期、提高抗高溫能力,而且該處理的葡萄果皮著色均勻、成色好,果肉可溶性糖含量較高。

Abstract The effects of different fruit bags on the maturity and quality of grape are different.In order to explore the effects of bagging grapes bunches with yellow-black bags,a grape variety Yinhong was used in this experiment. For Yinhong grape,bagging with yellow-black bags could effectively extend the harvest period,avoid high temprerature and sunburn,but there were color difference and sugar low.Six kinds of different bagging and bag-removing methods were carried out with white bags and yellow-black bags. The results showed that two weeks in advance use white bags instead of yellow-black bags was the best,which could delay the grape ripening,made the grape had a good capacity of high-temperature endurance,had a good and uniform peel colour,and had a relatively high sugar content.

在南方,葡萄市場供應(yīng)時間集中在七八月,高溫高濕,導(dǎo)致果實著色差、糖度低,難以滿足消費者的長期需求。因此,延遲或促成栽培,拉長葡萄的市場供應(yīng)期,填補市場空白,具有十分重要的意義。果實套袋作為一種安全有效的重要栽培措施,能均勻著色,提高果面光潔度,提高果品感官品質(zhì),減少農(nóng)藥污染,預(yù)防鳥害,增強果品的安全性[1-2]。此外,陸玫丹等[3]的研究表明,對鄞紅葡萄套外黃內(nèi)黑復(fù)合紙袋能有效延遲果實的成熟采收期。但外黃內(nèi)黑復(fù)合果袋內(nèi)部的黑色紙質(zhì)材料具有遮光作用,一定程度上影響果實品質(zhì),如著色變差、糖度降低、肉質(zhì)變軟等。因此,本研究將從不同套袋及摘袋時間方面探索在延遲葡萄成熟的同時,保證或提高葡萄品質(zhì)的栽培方式,以期為葡萄的延遲采收提供技術(shù)依據(jù)。
