摘 要：
为探究开沟覆膜滴灌技术对葡萄生育期土壤温度变化的影响,该文根据2016年进行的田间试验,分析不同滴灌水量和不同开沟模式下膜内外0～100 cm土层土温度变化,并采用方差分析比较不同灌水量和不同开沟模式下膜内外各土层温度的差异显著性。结果表明:各土层温度变化波动趋势与大气温度变化趋势基本保持一致,且大气温度的影响随土壤深度的增加而减弱,无论膜内土壤温度还是膜外土壤温度均在14～33℃之间波动;通过方差分析发现,滴灌水量对膜内0～60 cm、膜外0～40 cm土层温度影响差异显著。与低灌水处理相比,采用高灌水处理使膜内0～20 cm土层土壤温度降低2.9℃,使膜内20～40 cm、40～60 cm土层土壤温度分别提高1.8℃和0.36℃。在膜外,与低灌水处理相比,中、高灌水处理,使0～20 cm土层温度分别提高0.95℃和1.26℃,使20～40 cm土层土温提高约1℃。开沟模式对膜内和膜外土温影响差异不显著,适当增大开沟宽度,可以使膜内外土壤温度略有提高。

摘 要：
In order to explore the effect of the technology of drip irrigation with trenching and coating on soil temperature change during grape growth period,this paper analyzes the temperature variation of 0 ～ 100 cm soil layer inside and outside the membrane under different drip irrigation water volume and different trenching modes according to the field experiment conducted in 2016. The variance analysis method is used to compare the significant differences in temperature between the soil layers inside and outside the membrane under different irrigation volumes and different trenching modes. The results show that the fluctuation trend of temperature of each soil layer is consistent with the trend of atmospheric temperature,and the influence of atmospheric temperature is weakened with the increase of soil depth,regardless of whether the soil temperature in the membrane or the soil temperature outside the membrane is between 14 ℃ and 33 ℃. Through variance analysis,it is found that the effect of drip irrigation on the temperature of 0 ～ 60 cm in the membrane and 0 ～ 40 cm in the membrane is significant.Compared with the low-irrigation treatment,the high-irrigation treatment reduces the soil temperature of the 0 ～ 20 cm soil layer in the membrane by 2.9 ℃,and increases the soil temperature of the 20 ～ 40 cm and 40 ～ 60 cm soil layers in the membrane by 1.8 ℃ and 0.36 ℃,respectively. Outside the membrane,compared with low-irrigation treatment,the medium and high irrigation treatments increase the temperature of 0 ～ 20 cm soil layer by 0.95 ℃ and 1.26 ℃,respectively,and increase the soil temperature of 20 ～ 40 cm soil layer by about1 ℃. The effect of the trenching mode on the temperature inside the membrane and the temperature outside the membrane is not significant.Appropriately increasing the width of the trench can slightly increase the soil temperature inside and outside the membrane.
