| 摘 要： | 通过分析膜下滴灌棉田不同质地土壤水分动态变化,探讨不同土质棉田水平、垂直方向上土壤水分变化的基本规律。结果表明,2种土壤质地,水平方向均不适宜选择滴灌带正下方和膜间作为最佳墒情监测点,而垂直方向0~40 cm土层可以作为土壤墒情监测的深度。不同土质墒情监测的最佳位点,水平方向粘土为距离滴灌带-40 cm至20 cm处,砂土为-20 cm至20 cm处(均除0 cm滴灌带正下方),垂直方向二者均为0~40 cm处。

| Abstract: | This research is to analyze the moisture dynamics of different soil texture in cotton field drip-irrigated under film,and discusses the basic law of the soil moisture dynamic changes in different soil and in horizontal and vertical direction.The result shows that in the two kinds of soil,below the drip tape and between the film are not the best moisture monitoring sites in horizontal direction,but the 0~40 cm soil can be used as the monitoring depth of the soil moisture in vertical direction.The best monito... |
