| 摘 要： | 研究了纯作和套种对烟田土壤温度变化的影响,结果表明:8:00-19:00,各层土壤温度都随时间推移先升高后下降。5cm处,纯作土壤温度始终高于套种,10cm,15cm和20cm土温,分别在12:00,13:00和14:00之前表现为纯作高于套种,之后,套种高于纯作,两处理土壤温度继续升高,分别在16:00,17:00和18:00升至最高,然后开始下降,套种土壤温度升高和下降幅度均大于纯作,并且套种土壤温度日较差显著大于纯作。总体来说,8:00-19:00,5～20cm土层,套种土壤温度平均值和土壤积温均低于纯作。 |

| Abstract: | The effect of fule-cured tobacco monoculture and inter-cropping with wheat on soil temperature changes was studied.The results showed that the soil temperature rose first,and then fell from 8:00 to 19:00.The soil temperature of monoculture were higher than that of inter-cropp-ing all the time at the depth of 5cm soil.At 10cm,15cm and 20cm soil,the soil temperatures of monoculture were higher than those of inter-cropping,respectively,before 12:00,13:00 and 14:00,but lower afterward,though the soil temperature of two treatments continued to rise and reached to the highest at 16:00,17:00 and 18:00,respectively.The rising and falling extents of soil temperature were greater in inter-cropping than in monoculture,and the daily temperature differences of interplant were significantly bigger than that of monoculture.The mean and accumulated temperature at 5-20cm depth were all lower in inter-cropping than in monocuture soil from 8:00 to 19:00. |
