Abstract
為有效防治番茄白絹病，於番茄種植前植畦覆蓋0.25 mm PE塑膠布處理，可提高土表層5公分處之溫度達12℃，覆蓋塑膠布之處理最高地溫51℃，最低地溫27℃，調查期問15天內維持40℃以上之時數達119小時之多，對照不覆蓋之最高地溫39℃，最低地溫23℃，未有40℃以上之時數。種植前植畦覆蓋塑膠布處理，能有效控制番茄白絹病之發生，使土表及土表下5公分之白絹病菌核均未能存活，田間植株亦無白絹病之發生。植畦覆蓋塑膠布，並再添加有機綠肥，如苜蓿、太陽麻或玉米莖葉等，對番茄白絹病之防治效果比植畦覆蓋塑膠布單項處理為優。
For control of southern blight of tomato caused by Sclerotium rolfsii, mulching of planting row with transparent plastic sheet before planting was studied. The temperature under soil surface 5cm in depth could increase 12℃ after mulching and number of hour for soil temperature reached at or over 40℃ was 119 during the 15-day test period, while the soil temperature of control plot without mulching never reached 40℃. The highest and the lowest temperature of soil were 51℃ and 27℃ for the plot with mulching treatment, respectively, and were 39℃ and 23℃ for the control plot without mulching treatment, respectively. The mulching treastment was effective in controlling southern blight of tomato. The sclerotia of S. rolfsii could not survive in the soil surface and under soil surface 5 cm in depth. However, the planting row amended with green manure and mulched with plastic sheet was better for the disease control than the mulching treatment alone.
