| 摘 要： | 温度是影响棉花生长的重要因子。研究了晋南主产棉区——运城市棉花生育期气温变化的特点,结果表明,近年来运城市的终霜冻有20%的年份晚于4月1日(正常年份为3月上旬),早霜冻有27.3%的年份早于10月5日(正常年份为11月上中旬);在播种出苗期,气温不稳定,有66.6%的年份在最低气温10℃稳定通过3 d以后,又出现10℃以下的低温3 d左右;从苗期到吐絮期出现对棉花发育不良的气温均有10%以上的概率。

| Abstract: | Temperature is one important factor for cotton.The air temperature is analyzed in cotton production area in southern of Shanxi Province during cotton growth stages.In recent years,occurrence probability of final frost day after April 1 was 20%,which occurred during the first ten days in March in normal years;27.3% for early frost day before Oct.5 which occurred during the first and middle ten days in November in normal years.66.6% probability of low temperature years happened when air minimum temperature st... |
