套袋技术对奥冠红梨着色的影响

Effect of Bagging Treatments on Coloration Ratio of Aoguanhong Pear

对奥冠红梨进行套塑膜袋、塑膜袋加双层纸袋和双层纸袋三种套袋处理,发现套双层纸袋的效果最好,果实着色率最高且品质最好.在套双层纸袋处理中,对奥冠红梨进行不同时期的摘袋处理,发现应选择在8月28日左右即成熟期(9月15日)之前12-15天进行摘袋,果实着色率最高,且摘袋后着色速度最快;提前摘袋则着色差,且摘袋后着色速度慢.

Three kinds of bagging treatments were processed on the Aoguanhong pear fruits, including plastic bag, plastic bag plus double-layer paper bag and double-layer paper bag. The results showed that the double-layer paper bags effect was the best, the fruits coloration ratio was the highest, and the quality was the best. In the double-layer paper bag processing set, picked-bagging during different periods was processed on the Aoguanhong pear fruits. And the results showed that on August 28 should be selected on or about the maturity （September 15） before 12-15 d to pick bags, then the fruits coloration ratio was the highest, and the coloration rate was the quickest after picked-bagging. When picked-bagging was earlier, the fruits coloration ratio became worse, and the coloration rate became slower after picked-bagging.
