2002-2003年在会理石榴产区进行了不同纸袋、不同套袋时间和不同摘袋时间的果实套袋试验。结果表明,套白色单层袋的果实色泽最佳,条纹袋次之,黑色袋最差。不同纸袋套袋后果实与对照(不套袋)相比,单果重差异显著。其中,以套黑色袋果实最重,达427.37g。就含糖量而言,套袋均比不套袋有显著提高,其中以条纹袋最高,达12.78%,比对照(11.36%)提高了1.42%;同时,不同纸袋都显著降低了含酸量,其中以条纹袋最低(0.57%),比对照(0.63%)低0.06%.不同套袋时间对果实单果重和含糖量无显著影响,但显著降低了果实的含酸量,以6月3日套袋果实含酸量最低。摘袋时间对果实内部品质的影响未达到显著水平,但建议在采收前7天摘袋。
During 2002-2003, bagging experiments were conducted in Huili pomegranate producing areas with different paper bags, different bagging times and different bagging times. The results showed that the white one-layer bag of the best fruit color, stripe bag followed, the worst black bag. Different bagging results compared with the control (no bagging), fruit weight differences were significant. Among them, the heaviest black bag fruit, up to 427.37g. In terms of sugar content, bagging was significantly higher than that without bagging, with the stripe bag being the highest, up to 12.78%, 1.42% higher than the control (11.36%); at the same time, different paper bags significantly reduced the acid content (0.57%), which was 0.06% lower than that of the control (0.63%). Different bagging time had no significant effect on the fruit weight and sugar content, but significantly reduced the fruit acid content, Bagging fruit on the 3rd with the lowest acid content. The effect of picking time on the internal quality of the fruit did not reach a significant level, but it is advisable to pick the bag 7 days before harvesting.
