摘要
以番茄幼苗“欧耶”为试材，研究了宁夏地区覆膜加麦麸太阳能消毒处理对土壤日平均温度、日温差、日最高温度、高温持续时间及番茄发病率、产量的影响。结果表明：利用覆膜加麦麸太阳能消毒可显著提高土壤温度，明显降低番茄枯萎痛发病率，提高番茄产量；覆膜加麦麸可显著提高土壤日平均温度和日最高温度，其中10、20、30cm土壤日最高温度分别达到56．9、49．2、44．8℃，较CK分别提高10．5、8．6、6．4℃；增大了土壤日温差，其中0～20cm土层日温差差异显著；不同土层土壤温度超过40℃的天数百分比较CK显著增加；番茄枯萎病的发病率降低了9．53％，平均667m^2产量增加了679．4kg，且差异均显著。
Taking ＇Ouye＇tomato seedlings as experimental material, the effects of solarization with plastic-film mulching and wheat bran on daily average temperature, daily temperature range, maximum temperature and duration of high temperature of soil as well as the incidence and yield of tomato were studied in Ningxia region. The results showed that the use of film covering in addition with bran in soil solarization could significantly increase soil temperature which could significantly reduce the incidence of tomato blight and increase tomato yield. The soil daily average temperature and the daily maximum temperature were significantly increased in the condition of film covering in addition with bran. And the soil daily maximum temperature in the depth of 10,20,30 cm reached as high as 56. 9,49. 2,44. 8℃ with the amplification of 10. 5,8. 6,6.4℃ respectively. It was also showed that the soil daily temperature range increased with the most effect in the soil below 20 cm;the percentage of the days when soil temperature were higher than 40℃ was raised both in the soil with different depths. In a word,the soil solarization effect showed that the incidence of tomato blight reduced 9. 53% and the average area 667 m^2 yield increased 679. 4 kg.
