摘 要：
基于大田试验,以耐盐碱牧草草木樨为试验材料,分析了以每3 d E20蒸发皿水面蒸发量的50%为灌溉指标,耕作种植方式为平作和垄作下,盐碱地滴灌土壤剖面(距滴头横向30 cm,滴头垂直深度100 cm)含水率、电导率和p H值的变化特征。结果表明:灌溉结束后,垄作种植方式的电导率和p H值都比平作下降得比较明显,其中,垄作和平作种植方式滴头下方0~60 cm的平均电导率比灌前下降37.4%和21.8%,垄作在0~40 cm淋洗的效果较明显,较灌溉前0~40 cm土层平均电导率下降52.4%,平作在0~20 cm淋洗的效果较明显,较灌溉前0~20 cm平均电导率下降30.8%。

摘 要：
In the field trials,the saline-alkaline tolerance sweet clover is selected as experiment materials,the change characteristic of water content,EC and p H of the soil profile( 30 cm in horizontal direction and 100 cm in vertical direction) under drip irrigation under the cultivation patterns of flat planting and ridged planting with 50% of the surface evaporation amount of E20 evaporation pan per 3 days as irrigation index,is analyzed. The results show that EC and p H of ridged planting cultivation pattern are fallen more obviously than flat planting; the average EC in the layer of 0 ~ 60 cm under dropper declines by 37.4% and 21.8%,respectively,for ridged planting and flat planting than that before irrigation; ridged planting pattern has obvious leaching effect on the layer of 0 ~ 40 cm under dropper,the average EC declines by52.4% than that before irrigation; flat planting pattern has obvious leaching effect in the layer of under 0 ~ 20 cm dropper,the average EC declines by 30.8% than that before irrigation.
