摘　　要：【目的】本文研究了缓解攀枝花市的季节性干旱对芒果产量的影响,验证核技术合成新型保水剂的增产效果。【方法】通过保水剂+缓释肥、保水剂+常规施肥与只施用缓释肥、常规施肥的对比试验。【结果】施用保水剂比相应的对照土壤水分含量增加5.8%和8.3%,叶片的SPAD值增加9.6%和11.0%,达到显著水平;株产增加12.3%和28.5%,达极显著水平。【结论】核技术合成的新型保水剂不仅提高了土壤水分、保水效果好,还锁住了肥料成分不流失,芒果产量显著提高,适合在季节性干旱严重的攀西地区使用。【Objective】This study aimed to alleviate the effect of seasonal drought on Mango yield in Panzhihua city and verify the yield-increasing effect of new water-retaining agent synthesized by nuclear technology.【Method】a comparative experiment was conducted between water-retaining agent+slow-release fertilizer,water-retaining agent+conventional fertilizer and only slow-release fertilizer and conventional fertilizer.【Result】The water content of soil increased by 5.8%and 8.3%with water-retaining agent,and the SPAD value of leaves increased by 9.6%and 11.0%reached a significant level;Plant yield increased by 12.3%and 28.5%,reaching a very significant level.【Conclusion】The new water-retaining agent synthesized by nuclear technology not only improved soil moisture and water-retaining effect,but also locked up fertilizer components and significantly increased mango yield.It was suitable for use in Panxi area with severe seasonal drought.
