新沂市水稻“两迁”害虫发生发展的气象因子分析

摘要

The effect of meteorological conditions on development of two migra-tion of rice insects in Xinyi was ana-lyzed, and the causes were analyzed. The meteorological conditions during the in-sects immigration period were obtained, and the relationship between tempera-ture, rain days, precipitation, relative humidity and development of two migra-tion of rice insects was known. The re-sults provided scientific basis for the forecast and integrated control of two mi-gration of rice insects in Xinyi.%分析各主要气象要素对新沂市水稻“两迁”害虫的影响，并分析其原因。明确了当地“两迁”害虫迁入期的气象条件，及迁入后当地的温度、雨日、雨量、相对湿度与害虫发生蔓延密切的关系，为新沂“两迁”害虫的发生、发展预报及综合治理提供了科学依据。
