柑桔寒害问题,乃是当前世界柑桔生产中存在的一个主要问题。我所自1950年冬(原中南农科所)首次自湖南引入温州蜜柑以后,即开始进行断断续续的研究,经历了几次较大的冻害,也取得了一些感性认识。兹将对冻害问题的几点肤浅看法,提出供有关方面参考。一、寒害的周期性及今后演化趋向这是一个柑桔生产有冻害地区最关心的问题。因为周期性的冻害,常给柑桔生产带来灾难性的损失。而周期性冻害的规律如何,近年来逐渐有了一个共同的看法,即大约每隔十年 The problem of chilling injury in citrus is one of the major problems in citrus production in the world at present. Since the winter of 1950, the original Central South Agricultural Science Institute introduced the introduction of Wenzhou Satsuma from Hunan, I started the intermittent research and experienced several major frost damage and gained some perceptual knowledge. I will freeze on the issue of a few superficial views put forward for reference. First, the cycle of cold damage and the future evolution trend This is a citrus production areas are most concerned about the issue of frost damage. Because of periodic frost damage, citrus production often brings catastrophic losses. However, the law of periodic frost damage has gradually come to a common view in recent years that about every ten years
