中文摘要	【目的】探讨不同残膜和灌溉水平下土壤水分的时空分布,揭示残膜量对棉田土壤中水分分布影响,调控灌水。【方法】在连续15 a覆膜种植棉花的棉田设置0、225、450 kg /hm~2三个残膜梯度,全生育期设置3 450、4 650、5 850 m~3 /hm~2三个灌溉水平。分别在蕾期、花铃期、盛铃期灌水后第1、3、5 d取土测定其土壤含水率,分析不同处理对土壤水分变化趋势、横向、纵向的影响。【结果】土壤水分分布明显受到残膜含量与灌溉量的影响,灌溉量较小时, 450 kg /hm~2的残膜处理土壤含水率最低且灌水后第1 d到第5 d土壤含水率下降最多,随着灌溉量增加残膜处理土壤含水率相比对照也有所增加,当灌溉量达到5 850 m~3 /hm~2时,无残膜处理土壤含水率最低。垂直方向上在3 450 m~3 /hm~2灌溉量下, 450 kg /hm~2残膜处理在各土层土壤含水率均最少,当灌溉量为5 850 m~3 /hm~2时225、450 kg /hm~2残膜处理的各土层土壤含水率均大于0 kg /hm~2残膜处理,各处理土壤含水率随着土层加深而增加。【结论】不同灌溉水平下不同残膜处理土壤含水率不同,含残膜棉田相比无残膜棉田土壤含水率会随着灌溉量的增加增大,5 850 m~3 /hm~2灌量促进高残膜量棉田水分的均匀分布。
英文摘要	【Objective】Investigating the spatial and temporal of soil moisture distribution under plastic film and different irrigation levels in order to reveal the significance of the impact of the residual amount of plastic film on the soil which is cropping with cotton water distribution and the controlling of irrigation. 【Method】Three plastic film gradient 0 kg /hm~2,225 kg /hm~2 and 450 kg /hm~2 were set in the soil covered with film in the past 15 years in a row. During the whole growth period,three irrigation levels: 3, 450 m~3 / hm~2,4,6 50 m~3 /hm~2 and 5, 850 m~3 /hm~2 were set. Respectively,at the bud stage,during the blooming period,1,3,5 days later,soil were taken and tested to determine the moisture rate and analyze the horizontal and vertical impact on the trends of water change.【Result】The distribution of soil moisture content was significantly affected by the plastic film and the amount of irrigation. When the irrigation amount was small,the soil moisture reached the lowest point when the soil was treated with plastic film processing 450 kg /hm~2. What’s more,the soil moisture from the first day to the fifth day after irrigation declined the largest during the investigation period,and with the irrigation increased,soil moisture plastic film processing would also increase comparing with the check. When irrigation reached 5, 850 m~3 /hm~2,the rate of moisture in soil with no plastic film was the lowest. 3,4 50 m~3 /hm~2 irrigation at the vertical direction,the rate of moisture in different of soils was the lowest. When the irrigation capacity reached 5, 850 m~3 /hm~2,the soil moisture at the different levels by 450 kg /hm~2 treatment was larger than the control treatment. When the depth of the soil increased,the rate of moisture in soild would also increase. 【Conclusion】Under different irrigation levels,different plastic film processing of soil moisture would have different rate of moisture in soils. Compared the non - treated plastic film plastic film processing and plastic film processing,5,850 m~3 /hm~2 irrigation amount helped the balanced distribution of soil moisture.
