本研究基于2020-2022年在贵州米箩等20个红心猕猴桃基地进行的调查,以及同期气象资料分析,探讨了红心猕猴桃黑斑病发生与连阴雨天气的关联性.通过收集5月1日—7月31日逐日平均温度、降水量、平均相对湿度、平均低云量等气象资料,分析该期间连阴雨天气特征,结合黑斑病发生地、发病率,探讨了黑斑病与连阴雨天气的定量关系,确定了红心猕猴桃黑斑病发生的连阴雨天气指标阈值.研究发现,红心猕猴桃黑斑病与品种有较大的关系,且在5-7月红心猕猴桃果实生长期内,当连阴雨天气在15 d及以上,同时日平均温度在20.0℃及以上、日平均相对湿度在90％及以上、日平均低云量在0.90及以上时,红心猕猴桃果实极易感染黑斑病,该指标可以作为红心猕猴桃黑斑病发生的气象预警指标.根据这些发现,研究建立了红心猕猴桃黑斑病气象灾害评估模型,为红心猕猴桃生产开展黑斑病气象评估服务提供科学参考.
Analysis of Meteorological Conditions and Evaluation Model for Red Cartridge Kiwifruit Black Spot Disease
With the continuous expansion of planting scale of kiwifruit in Guizhou,the harm degree of black spot disease of kiwifruit is increasing,and the economic loss is also increasing.This paper analyzed the characteristics of continuous rainy weather in May-July from 2020 to 2022 by using the survey data of 20 red cartridge kiwifruit bases such as Guizhou Miluo and their fruit black spot disease,and the daily average temperature,precipitation,average relative humidity and average low cloud cover during the growth period of red cartridge kiwifruit from May 1 to July 31.The quantitative relationship between black spot disease and continuous rainy weather was discussed according to the occurrence place and incidence of black spot disease,and the threshold of continuous rainy weather was determined.The results showed that black spot disease of red cartridge kiwifruit was closely related to varieties.During the growth period of red cartridge kiwifruit from May to July,when the continuous rainy weather was 15 days and above,the daily average temperature was 20.0℃ and above,the daily average relative humidity was 90% and above,and the daily average low cloud cover was 0.90 and above,black spot disease would definitely occur in red cartridge kiwifruit.This index can be used as a meteorological early warning index for the occurrence of black spot of red cartridge kiwifruit.The meteorological disaster assessment model of red cartridge kiwifruit black spot was established to provide scientific reference for the meteorological assessment service of red cartridge kiwifruit production.
