干烧心病是我国近年来大白菜生产和贮藏中危害较重的一种病害。发病原因主要是生理病害,同时也与气象因子有密切关系。本文通过大白菜干烧心病与主要气象因子关系的分析,结果表明,空气湿度是直接影响干烧心病的主要气象因子,降水量、日照和温度是间接影响干烧心病的气象因子.即在大白菜生长季节中,降水量多、空气湿度大、寡日照和气温低的年份,大白菜干烧心病发病较轻;反之,降水量少、空气湿度小、日照时间长和气温较高的年份,大白菜干烧心病发病较重。
Sick heart disease is one of the most harmful diseases in Chinese cabbage production and storage in recent years. The main cause of the disease is physiological diseases, but also with weather factors are closely related. The results showed that air humidity was the main meteorological factor that directly affected the heartburn disease, and the precipitation, sunshine and temperature were the meteorological factors indirectly affecting the heartburn disease. Chinese cabbage growth season, the precipitation is more, the air humidity, oligospermia and low temperatures, cabbage dry heart disease incidence less; the contrary, less precipitation, air humidity, long sunshine and high temperatures in the year, Chinese cabbage dry heart disease heavier.
