摘要：

为明确随水滴施“糖-酸-肥”调理剂对重度盐渍化棉田土壤环境和棉花产量的影响，本研究于2025年在新疆喀什地区巴楚县现代农业产业园开展田间试验。试验设置常规施肥(CK)、葡萄糖(C)、草酸(H)、磷酸一铵(P)及其不同复配共8个处理(CK、C、H、P、C+H、C+P、H+P、C+H+P)。调理剂于棉花苗期和蕾期第1次灌水时随水滴施，并在施后3 d采集不同土层土壤样本，测定土壤pH、有效磷含量、棉花干物质量和产量。结果表明：“糖-酸-肥”调理剂对土壤pH的影响存在时期和土层差异，其中，C+H+P（葡萄糖+草酸+磷酸一铵）处理在0~5 cm土层的pH降幅最大，苗期和蕾期分别较CK降低0.40和0.31个单位。含磷酸一铵的处理均显著提高各采样土层的有效磷含量，其中，C+H+P处理在0~5 cm土层中，苗期和蕾期的有效磷含量较CK分别提高342.69%和323.36%，增幅最大。C+H+P处理的总干物质量和籽棉产量分别较CK显著增加62.94%和57.84%。在本试验条件下，随水滴施葡萄糖、草酸和磷酸一铵的组合可改善重度盐渍化棉田的磷素供应，并促进棉花生长和增产，其中C+H+P处理的综合效果最佳。该研究为干旱区重度盐渍化棉田的水肥调控与产量提升提供了有价值的参考。

Abstract:

To evaluate the effects of drip-applied sugar-acid-fertilizer combinations on soil properties and cotton yield in severely saline-alkali cotton fields, a field experiment was conducted in 2025 at the Modern Agricultural Industrial Park in Bachu County, Kashgar, Xinjiang. Eight treatments were established: conventional fertilization (CK), glucose (C), oxalic acid (H), monoammonium phosphate (P), C+H, C+P, H+P, and C+H+P. The amendments were applied through drip irrigation during the first irrigation at the seedling and budding stages, and soil samples were collected from different soil layers 3 days after application. Soil pH and available phosphorus were measured, and cotton dry matter accumulation and yield were determined. The results showed that soil pH responses varied with growth stage and soil depth. The C+H+P treatment produced the greatest decrease in pH in the 0-5 cm layer, by 0.40 and 0.31 units at the seedling and budding stages, respectively, compared with CK. Treatments containing monoammonium phosphate significantly increased available phosphorus at all sampled depths. Under C+H+P, available phosphorus in the 0-5 cm layer increased by 342.69% and 323.36% at the seedling and budding stages, respectively. The C+H+P treatment increased total dry matter accumulation and seed cotton yield by 62.94% and 57.84%, respectively, relative to CK. Under the conditions of this study, drip application of glucose, oxalic acid, and monoammonium phosphate improved phosphorus availability and promoted cotton growth and yield, with C+H+P showing the most favorable overall effect. This study provides a valuable reference for water and fertilizer regulation and yield improvement in severely saline-alkali cotton fields in arid areas.
