周期性的寒害,严重威胁着我国江南各省的枯柑生产。认识寒害发生的原因,并相应地提出经济有效的预防措施,是江南桔柑生产者和科研工作者共同关心的问题。笔者自1952年开始,即着手对这一问题进行研究。经过断断续的探讨和实践,初步探明了我省柑桔寒害,多发生于太阳黑子低值年,并存在一个比较明显的以11年为周期的规律。
Cyclical cold damage seriously threatens the production of dry orange in all provinces in the south of our country. Understanding the causes of cold damage and correspondingly putting forward economically effective preventive measures are issues of common concern to producers and researchers of jiangnan citrus. Since 1952, the author has started to study this issue. After intermittent exploration and practice, preliminary identification of the province of citrus cold damage occurred in the low sunspot years, and there is a more obvious 11-year cycle of the law.
