不同套袋材料对‘红美人’杂柑果实品质及经济效益的影响

Effects of Different Bagging Materials on Fruit Quality of Citrus Hybrid‘Ehime Kashi No.28'

【目的】探讨不同材质的套袋对‘红美人’杂柑果实品质的影响,为寻求其适宜的套袋材料。【方法】采用市售不同套袋材料,对红美人杂柑进行套袋试验。【结果】不套袋红美人杂柑的果实商品果率仅为41.3%,而套袋能明显改善果实外观品质,使果面着色更均匀,商品果率均高于65.3%,最高为采用外黄内黑单层纸袋套袋,商品果率高达76.0%。套袋基本能提高果实可溶性固形物含量、降低可滴定酸含量,其中外黄内黑三层纸袋的果实可溶性固形物含量最高,达11.6%,显著高于不套袋;用外黄内黑二层纸袋和外黄内黑三层纸袋套袋能显著提高果实固酸比,提升果实风味。经济效益分析亦表明,套袋后株利润提高了118.0~189.5元,能显著提高果农的经济效益。【结论】套袋能提高红美人杂柑果实商品果率,提升果实品质,增加果农收益。在套袋时,如果考虑采摘后果实统货销售,可以采用外黄内黑单层纸袋,果实外观品质好、经济效益更高;如要生产精品果,可以采用外黄内黑三层纸袋,套袋果实的可溶性固形物含量和固酸比高、品质好。

【Objective】Explore the effect of different bagging materials on the fruit quality of citrus hybrid‘Ehime Kashi No.28'in order to select suitable bagging materials.【Method】Different commercially bagging materials were applied on citrus hybrid‘Ehime Kashi No.28'.【Result】The results showed that the commodity fruit rate without bagging was only 41.3%,while bagging could significantly improved the appearance quality of fruits,resulting in uniform coloring and commodity fruit rates of over 65.3%.The highest commodity fruit rate was achieved by using a single layer of yellow and black paper bags,with a high commodity rate of 76.0%.At the same time,bagging could also increase the soluble solids content of fruits and reduce titratable acids.The outer yellow and inner black three-layer paper bag could lead to the highest soluble solids content of fruits(11.6%)significantly higher than no bagging.The outer yellow and inner black two-layer paper bag and the outer yellow and inner black threelayer paper bag could significantly increase the ratio of soluble solids content to titratable acidity content and enhance fruit flavor.The economic benefit analysis also showed that bagging can significantly improve the economic benefits of fruit farmers,and the plant output value of bagging was increased by 118.0 to 189.5 yuan.【Conclusion】Bagging could improve commodity fruit rate and fruit quality of citrus hybrid‘Ehime Kashi No.28'and increase farmers'income.When considering fruits were sold on a wholesale price,outer yellow and inner black single-layer paper bag should be taken for good appearance and high economic benefits.When considering high-end fruits were sold,outer yellow and inner black three-layer paper bag should be taken,resulting in higher soluble solids content and ratio of soluble solids content to titratable acidity content and high fruit quality.
