中文摘要	河套灌区杭锦后旗各质地盐渍土壤的水分入渗性能、温度及含盐量不同,使土壤改良效果存在差异。为研究沙穴种植番茄对不同土质的土壤水分、温度、盐分的迁移规律,通过在土柱中填装3种典型土质(砂壤土、粉壤土、黏壤土),同时布设沙穴,探索在滴灌条件下种植加工番茄以改良不同土壤质地的可行性。结果表明:沙穴种植对不同土质的水热盐迁移影响不同,沙穴种植能显著改善黏壤土土壤水分入渗性能,提高根系层土壤的湿润区面积及含水率,在深度20~40 cm相对增加了24.15%,但降低了砂壤土和粉壤土的保水性,土壤剖面含水率呈上干下湿的特点;沙穴种植可显著提高作物生长初期黏壤土的温度(P<0.05),平均增温3.64 ℃,有利于初期幼苗生长发育,但对原状砂壤土和粉壤土的温度变化不显著,生育后期土壤温度随着气温变化均呈下降趋势;沙穴种植对土壤盐分具有淋洗作用,在深度>20 cm处,粉壤土和黏壤土的盐分淋洗效果显著(P<0.05),平均相对脱盐率达23.28%和56.29%。综合分析沙穴种植对不同土质盐渍土土壤水热盐迁移规律,得出在杭锦后旗3种典型盐渍土中,黏壤土是最适宜沙穴改良方式的土质。
英文摘要	There are many differences in the water infiltration, temperature, and salt content of the saline alkali soil in the Hetao irrigation district of Hanggin Rear Banner, which leads to different effects on soil improvement. This study aimed to examine the transport of soil moisture, temperature, and salt in different soil bysand cave planting tomatoes in saline soil by setting sand caves on three typical soils (sandy loam, silty loam, and clay loam) in the soil column. The results showed that sand cave planting has different effects on the distribution of water, heat, and salt in different soils. Sand cave planting significantly improves the water infiltration performance of silty clay loam soil, it increases the area and moisture content of root layer soil, and it can be increased by 24.15% at a depth of 20-40 cm. However, it reduced the water holding capacity of sandy loam and silty loam soil, and the water content of the soil profile was dry in the upper part and wet in the lower part. The temperature of undisturbed clay loam increased by 3.64 °C at the early stage of crop growth (P<0.05). These results show that there was no significant change in the temperature of sandy loam soil and silty loam soil, and the soil temperature showed a downward trend with the change in air temperature in the later growth stage. Additionally, the sand cave structure had a leaching effect on soil salt, the salt leaching effect of silt loam and clay loam was significant (P<0.05) at a depth of >20 cm, and the average relative desalination rate was 23.28% and 56.29%, respectively. Based on a comprehensive analysis of the law of water, heat, and salt transport of saline alkali soil in different soils by sand cave planting, it is concluded that among the three typical saline alkali soil in Hanggin Rear Banner, clay loam is the most suitable soil for sand cave planting. The research results inform the use of water-saving irrigation and the improvement of clay, saline soil to enable sustainable development of agricultural saline soil planting in arid areas.
