摘要： 【研究目的】通过探讨保水剂对南丰蜜橘园土壤的保水效应，可为其丰产优质栽培管理提供理论依据。【方法】以“杨小-26”南丰蜜橘为试验材料，探讨了RT-3005KM保水剂不同处理下南丰蜜橘园土壤含水量的变化。【结果】结果表明：0-20cm土层土壤含水量不随保水剂用量的变化而呈一定的规律性。20-40cm土层保水剂处理的土壤含水量总体高于对照并随保水剂用量的增加而增加。40-60cm与60-80cm土层保水剂处理的土壤含水量随着保水剂的增加而降低；降雨后40-60cm土层土壤含水量高于60-80cm土层，保水剂在40-60cm土层似乎有一个吸水高峰。【结论】保水剂处理在一定程度上提高了南丰蜜橘园土壤含水量。

Abstract: [OBJECTIVE] Effects of water-keeping from super absorbent polymer in Nanfeng mandarin orchard were studied in order to provide a theoretical basis for high-yield and good-quality of Nanfeng mandarin. [METHOD]The research took ‘Yangxiao 26’as experimental material to study the effect of the RT-3005KM super absorbent polymer on soil moisture content of Nanfeng mandarin. [RESULTS] The results indicated that the soil moisture content in 0-20 cm soil layer was not distinct with the amount of super absorbent polymer. Soil moisture content heightened with the super absorbent polymer increasing in 20-40cm soil layer. Soil moisture content decreased with the super absorbent polymer increasing in 40-60cm and 60-80cm soil layer, respectively. The soil moisture content with the same treatment in 40-60cm soil layer was higher than that in 60-80cm after rainfall. It seemed that there was a peak of water absorption treated with super absorbent polymer in 40-60cm soil layer. [CONCLUSION] On the whole, the super absorbent polymer could increase the soil moisture content of Nanfeng mandarin.
