摘要
为科学评估山东省茶树冻害影响情况,将山东省茶树冻害分为越冬期和春茶期冻害两类,分别找出影响两类冻害发生的主要气象因子,通过多元线性回归分别建立了山东省茶树越冬期和春茶期冻害减产预测模型。经验证,所得预测模型准确率较高,可以用来指导茶农科学防冻,提高茶叶产量和品质,推动山东省茶产业高质量发展。
In order to scientifically evaluate the impact freezing damage on tea plants in Shandong,the freezing dam-age to tea plants was divided into two categories:overwintering period and spring tea period.The main meteorologi-cal factors affecting the occurrence of the two types of freezing damage in Shandong were identified,and multiple lin-ear regression was performed to establish prediction models for the reduction rate of freezing damage during the over-wintering and spring tea periods in Shandong.The accuracy of the prediction models was verified to be high.The re-sults indicate that forecasting models and influencing factors can be used to guide tea farmers to scientifically pre-vent freezing,improve tea yield and quality,and promote the high-quality development of Shandong's tea industry.
