“清明断雪,谷雨断霜”,这是徐淮地区早春的气象规律。而这一阶段又是桑树萌芽时期,因此,本地区经常会出现晚霜为害,造成桑园春叶减产,影响春蚕生产。为加强防霜措施,准确预测霜害是重要一环。为此,我们将日本崛提出的气象因子积分预测法(据南泽吉三郎著《栽桑学》,1984;沈增学等译,东南大学出版社,1992),运用于本地晚霜的预
“Qingming off snow, Guyu off frost”, which is Xuhuai region early spring meteorological laws. And this period is the mulberry germination period, therefore, the night cream often appears in the region damage, resulting in mulberry spring leaf cut, affecting the production of spring silkworm. In order to strengthen the anti-frost measures, accurate prediction of frost damage is an important part.
