| 摘 要： | １９８６～１９９６年在石家庄河北棉花所黄、枯萎病混生病圃，对中棉所１２每年８月２０～２５日进行黄萎病调查，并与当地６～８月每旬的平均气温、降水量、日照时数和空气相对湿度等与发生黄萎病关系进行单项和综合分析。结果表明，７月份气温２７℃是发病轻重的转折点，７月中下旬的气温是影响黄萎病发病强度的主要因素，可分为高温、低湿、少雨轻病年和低温、高湿、多雨重病年，两者出现频率接近５０％。经过对黄萎病指（Ｙ）与所有因子逐步回归分析，入选因子为７月中旬湿度（Ｘ５）、６月下旬降水量（Ｘ１２）、７月中旬降水量（Ｘ１４）、７月下旬日照时数（Ｘ２４）和６月下旬平均气温（Ｘ３０），得出回归方程可试用于黄萎病发病的预测预报。
