cold injury
damage caused by clod
winter drying
winter killing
winterkilling
Examples
- Analysis of meteorological elements causing chilling injury to fruit trees in 2003 and defensive measures
2003年果树寒害气象因素分析及防御对策 - A wavelet analysis was made to the wintertime integrative chilling damage index , time - coefficients of the first characteristic vector field and the second eigenvector field of wintertime integrative chilling damage index
对广东冬季综合寒害指数和广东冬季综合寒害指数第一特征向量的时间系数、第二特征向量的时间系数进行了小波分解。 - Pca of x1 , x2and x3 successions was done , and from these three eigenvector fields , a principal component that its physical meaning is clear and its variance deficiency contribution rate is large ( over 75 % ) is found . and that principal component was defined as an integrative chilling damage index
将寒害指标x _ 1 、 x _ 2 、 x _ 3序列作主要分量分析，从3个特征向量场中找出了一个物理意义清晰、方差贡献率大(大于75 )的主要分量，将其定义为综合寒害指数。 - Based on those , the concept of chilling process was put forward according to the lowest biologic temperature of main tropic and south sub tropic crop and fruit in guangdong and the low temperature ( environment temperature 5 . 0 ) which is harmful to those crop and fruit . with the lowest air temperature ( the daily lowest air temperature ) x1 , the lasting days of low temperature x2 and an integrative physical element - - negative accumulated temperature x3 in which the effect of the intense and lasting days of low temperature were considered , the correlation coefficient of those indexes were calculated and analyzed , and the results showed that there are apparent linear correlations among them
在此基础上，以广东主要热带南亚热带作物的生物学下限温度为依据，从这些作物受寒害的起点温度(环境温度5 . 0 )出发，提出了寒害过程的概念，并用寒害过程低温的强度(逐日最低气温) x _ 1 、低温的持续时间(天数) x _ 2及考虑了低温的强度和持续时间综合作用的物理量负积温x _ 3这3个指标来描述寒害的强度，研究了广东历年冬季寒害的变化，分析了这3个指标间的相关系数，结果表明它们之间互相存在显著的相关关系。 - In order to provide scientific advice for wintertime agricultural production in guangdong province , we analyzed and studied the yearly variations and spatial distribution of the winter chilling damage in guangdong for the latest 44 years by using mean daily temperature and daily minimum temperature of 22 meteorological stations in guangdong from december , 1957 to february , 2001
用广东省22个分布较均匀的代表站1957年12月? 2001年2月冬季( 12月? 2月)逐日平均气温和最低气温资料，对广东省近44年来冬季寒害的发生规律及地域分布特征进行了分析和研究，为广东省冬季农业生产提供科学指导。
