台州地区农科所在宁波市镇海区病虫观测站合作下,利用观测站1955～1980年晚稻稻瘟病发生为害调查的历史资料,应用电子计算机,通过发病程度与气象因子相关性普查和2300余个因子的反复筛选,选出具有良好预测能力,可体现稻瘟病流行学观点的3个气温预测因子(2月下旬～3月中旬平均最高气温、7月中旬平均气温和8月上旬平均气温),并经数理统计分析,建立了“气温概 With the cooperation of the pest and disease observation station of Zhenhai District, Ningbo City, Taizhou, the historical data of rice blast occurrence in late rice from 1955 to 1980 were analyzed by using the computer. According to the general survey of the correlation between the incidence and meteorological factors and over 2300 Three temperature predictors (mid-February, mid-March mean maximum temperature, mid-July average temperature and early August average air temperature) with good predictive ability and epidemic perspectives of blast resistance were selected. And by mathematical statistics analysis, the establishment of a "temperature summary
