摘　　要：为了明确基于高原耐低温菌群的秸秆生物反应堆技术的应用效果,本文通过对比分析方法,研究秸秆生物反应堆处理下的温室温度和油麦菜生长状况。结果表明:在试验期间,秸秆生物反应堆温度始终50℃以上,生物反应堆放热提高了反应堆处理(SY)处理温室内温度,在试验期内9:00和21:00的SY处理温室内温度提升效果明显,平均温度分别比对照增加2.45℃和1.95℃,9:00和21:00的SY处理温室内最低温度分别是CK的5.86倍和1.5倍,处理间差异分别呈极显著水平(P<0.01)和显著水平(P<0.05),但在15:00,处理间温度差异不明显。SY处理温室内最低温度的升高,改善了油麦菜的生长状况,其功能叶叶长、叶片数、株高和单株鲜重、干重等指标均极显著高于对照(P<0.01)。因此,基于高原耐低温菌群的秸秆生物反应堆技术,对温室油麦菜生产中的增温和增产效果明显,这为高寒地区冬季温室秸秆生物反应堆技术的推广提供生产依据。In order to clarify the application effect of straw bioreactor technology based on low temperature resistant flora in plateau,the greenhouse temperature and the growth of oil and wheat vegetables under the treatment of straw bioreactor,by the way of the comparative analysis.The results showed that the temperature of straw bioreactor was always above 50℃,and the stacking heat of biological reaction increased the temperature in SY treatment green⁃house during the experiment period.The average temperatures at 9:00 and 21:00 in SY treatment respectively in⁃creased 2.45℃and 1.95℃than those in the CK,especially for SY treatment at 9:00 and 21:00,the minimum tem⁃perature in SY treatment greenhouse was 5.86 times and 1.5 times of CK respectively,and the difference between treatments was very significant(P<0.01)and significant(P<0.05),but there was no significant difference in tempera⁃ture at 15:00.Compared with the control,the increase of the minimum temperature in the greenhouse treated with SY treatment improved the growth status of oil wheat vegetables.The indexes of functional leaf length,leaf number,plant height,fresh weight and dry weight per plant were significantly higher than those of the control(P<0.01).Therefore,the straw bioreactor technology based on plateau low-temperature resistant bacteria has an obvious effect on increasing temperature and yield in the production of greenhouse oil,wheat and vegetables,which provides a pro⁃duction basis for the popularization of greenhouse straw bioreactor technology in winter in alpine region.
