【摘要】 为了研究气象条件对小麦蚜虫百株蚜量的影响,选用山东省东平县1976—2004年小麦蚜虫高峰期百株蚜量及成灾面积数据资料,将逐旬气象因子进行"膨化处理",确定最理想的相关因子,通过分析其对应的气象条件之间的相关性,说明小麦蚜虫的发生发展主要与降水和日照时数两个因子有关。小麦蚜虫百株蚜量与4月上、中旬平均相对湿度呈负相关关系,与5月中、下旬降水量呈正相关关系;小麦受灾面积与4月上旬日照时数呈正相关关系。更多还原

【Abstract】 For researching the influence between meteorological condition and the amount of aphids which one hundred plants,based on the amount of aphids which one hundred plants,the damage area of wheat in Dongping county of Shandong province from 1976 to 2004."Penghua" the related meteorological conditions,and ascertain the best factors.Thought analyzing the relativity of the corresponding meteorological condition,two factors affecting the occurrence and development of Wheat aphids were precipitation and sunshine hours.The results showed the amount of aphids which one hundred plants was negative correlation with the average relative humidity of beginning and middle of April,correlation with middle and late of May.The damage area of wheat was correlation with sunshine hours of beginning of April.更多还原
