柑桔冻害,是我国江南柑桔主产区北部地带(湖北、湖南、江西、浙江等省)某些地点、柑桔生产发展的一个障碍。因此,柑桔避冻已成为科学界密切注意和高度重视的科研课题。根据我们在湖南省大庸县各地的实地考察和研究,冬季山坡一定高度范围内存在的“大气逆温层”,如能充分加以利用,将为山区柑桔生产开拓新的前景。本文围绕低温对柑桔的危害和冬季山地逆温层进行分析研究,试图阐明冬季山地逆温层在柑桔避冻方面利用的意义。
Citrus frost damage is an obstacle to the development of citrus production in certain locations in the northern part of the main producing areas of citrus in southern China (Hubei, Hunan, Jiangxi and Zhejiang provinces). Therefore, the citrus antifreeze has become a scientific research topic that the scientific community pays close attention to and attaches great importance to. According to our field investigation and research in Dayong County of Hunan Province, the “atmospheric inversion layer” existing within a certain height of winter slopes, if fully utilized, will open up new prospects for mountain citrus production. This paper focuses on the hazards of low temperature on citrus and winter mountain inversion layer in order to elucidate the significance of winter in-mountain inversion layer in the use of citrus oranges.
