四川红桔年产量已达50万吨左右。随着红桔生产的发展,国内经济的搞活,鲜果贮藏和长途运输量不断增加。然而红桔果实存在易发泡、枯水和腐烂,极不耐贮运等问题,贮运中损耗甚重。为此,我们在1985——1989年进行红桔果实保鲜防腐综合技术研究的基础上,于1989年——1990年与资中县农业局合作,开展了几种保鲜防腐剂减少红桔果实贮藏期和长途运输中总损耗的试验。供试果实为1989年11月18日。于资中县文江乡果农刘茂坤的红桔树中熟果。采后24小时左右药剂浸果,设红桔专用保鲜防腐剂100倍液、桔腐净100倍液、2.4—D500ppm+培福朗1000倍液、2.4—D500PPm Sichuan red orange annual output has reached 500,000 tons. With the development of the production of kumquat and the revitalization of the domestic economy, the storage of fresh fruits and the long-distance transportation have been on the increase. However, the existence of red orange fruit easy to foam, dry and rot, very intolerant storage and transportation problems, storage loss is very heavy. Therefore, on the basis of comprehensive researches on the preservation and anticorrosive of red tangerine fruits from 1985 to 1989, we conducted several preservatives to reduce the storage period of red tangerine fruit during the period from 1989 to 1990 in cooperation with Zizhong Agricultural Bureau. And long-distance transport total loss test. The test fruits for November 18, 1989. In Zixian Wenjiang rural fruit farmers Liu Maokun red orange tree ripe fruit. About 24 hours after harvest Pharmacological immersion, set red preservative preservative 100 times the liquid, orange rotten 100 times the liquid, 2.4-D500ppm + Peifu Long 1000 times, 2.4-D500PPm
