一、引言锦橙是优良的甜橙中熟品种之一,果形美观,风味可口,特别适于我省温暖湿润的地区发展。在万县地区十一月下旬已开始成熟。由于成熟期一致,产品集中上市,而不能周年供应。在交通条件较差的地方还带来了运输方面的困难。为了进一步解决柑桔延迟供应的问题,国外已在柑桔采收前向柑桔树喷射稳果药剂,实行“挂果贮藏”。但在国内管理水平较低的情况下,延迟采收期,能否达到稳果效果,和对次年柑桔产量有无影响,均是值得探讨的问题。为此,我们于一九七八年十二月初在开县盛山园艺场进行了试验。 I. INTRODUCTION Jincheng is one of the finest sweet orange ripe varieties with beautiful fruit shape and delicious flavor. It is especially suitable for the warm and humid area in our province. In Wan County area has begun to mature in late November. Due to the same maturity, the product focused on the market, but not the annual supply. In poor traffic conditions also brought transport difficulties. In order to further solve the problem of postponed supply of citrus, foreign countries have already sprayed stable fruit medicaments to citrus trees prior to the harvest of citrus fruits and implemented “fruiting-fruit storage”. However, under the condition of low level of domestic management, it is worth discussing whether the delay of harvesting period can achieve the effect of stabilizing the fruit and the impact on the output of the next year’s citrus. To this end, we conducted a trial in Kaiyuan Shengshan Horticultural Field in early December 1978.
