摘要
[目的]明确小麦赤霉病发生的各影响因子,分析各因子不同量级对病害流行的影响.[方法]以2000年以来的数据为基础,分析江淮南部丘陵地区小麦赤霉病大流行各发生影响因子量以及各因子不同量级对病害流行的抑制作用.[结果]菌源的存在是赤霉病发生的前提条件;雨水是赤霉病发生的主导性影响因子;正常年份温度都能满足病害流行要求.[结论]研究结果为赤霉病测报及大面积防治提供了参考.
Abstract
[Objective] The aim was to clear influencing factors for the occurrence of wheat gibberellic disease and analyze the influencing degree of all factors.[Method] Based on the data since 2000, we analyzed influencing factors for the occurrence of wheat gibberellic disease in the hilly area of southern Jianghuan as well as the influencing degree of all factors.[Result] The existence of bacteria source was the precondition for occurrence of wheat gibberellic disease.The rainwater was main influencing factor for occurrence of wheat gibberellic disease.The temperature could satisfy the demand for occurrence of wheat gibberellic disease in normal years.[Conclusion] The results provide reference for prediction of wheat gibberellic disease and large area control.
