摘　　要：分析了山东省广饶县2005年与2006年冬季塑料大棚栽培草莓从扣膜至头茬采摘期的主要气象因素对产量的影响，总结出2006年草莓产量低、收入少的主要原因是：2006年日平均气温降至20℃以下的日期明显偏晚，不利于花芽分化；10月气温偏高，始摘期与采摘盛期提前；2007年1～2月气温明显偏高，使头茬后期草莓果实生长时间缩短；2006年雾与轻雾日数多，光照不足，白天增温缓慢，增幅小，昼夜温差小，不利于果实膨大；白粉病的发生程度亦重于2005年。The effect of major meteorological factors on yield of cultured strawberry from coated with a layer to the first picking period in winter of 2005 and 2006 was analyzed. It was found that the main reasons of low yield and economic efficient in 2006 were as follows ： the date of daily average temperature down to 20 ℃ was distinctly delayed in 2006, which was not conducive to flower bud differentiation. The first picking period and major onset of picking were both ahead because temperature was higher than perennial temperature in Oct. The temperature was distinct high from Jan. to Feb, of 2007 and it made growing time short in late period of first stubble. There were many reasons that were not conducive to fruit inflating. Such as too much fog and mist, lake of sunlight, slowly rise in temperature during daytime, little rise range of tem- perature, little between day and night. In addition, the powdery mildew was more serious than that in 2005.
