Brackish water can promote physicochemical changes in the soil. Aiming to mitigate the effect of excess salts in the soil, the use of organic matter promotes restructuring. The aim was to evaluate the productive and nutritional characteristics of cactus pear under different brackish water depths (ID) and levels of organic matter (OM). A factorial arrangement of 4 × 4 × 4 with four replications was utilized. Plots consisted of ID (0, 12, 20, and 28% reference evapotranspiration-ETo), and subplots were composed of OM levels (0, 15, 30, and 45 t/ha) and days after planting (DAP; 180, 270, 360, and 450 days). The growth, yield, and chemical composition of cactus pear were affected by ID and OM and/or by their interaction. The regular and increasing application of ID from 192 to 456 mm/year and a rainfall of 110 mm/year in cactus pear crops in biosaline systems improves the growth, freshness, dry matter yields, accumulation capacity per unit area, and chemical composition of cactus pear. The increase in OM up to the range from 30 to 45 Mg/ha linearly increases the agronomic performance of cactus pear. Biosaline systems with cactus pear should be adopted with the combined use of regular supplementary ID and OM, measuring at 304 mm/year and 45 Mg/ha, respectively.
微咸水可促进土壤的物理化学变化。为减轻土壤中盐分过多的影响，使用有机物质可促进土壤结构重组。本研究旨在评估不同微咸水深度（ID）和有机物质（OM）水平下仙人掌梨的生产和营养特性。采用4×4×4析因设计，重复4次。小区由ID（0、12、20和28%参考蒸散量-ETo）组成，亚小区由OM水平（0、15、30和45吨/公顷）和种植后天数（DAP；180、270、360和450天）组成。仙人掌梨的生长、产量和化学成分受ID和OM及其相互作用的影响。在生物盐系统的仙人掌梨作物中，每年从192毫米增加到456毫米的ID定期施用以及每年110毫米的降雨量，可改善仙人掌梨的生长、新鲜度、干物质产量、单位面积积累能力和化学成分。OM增加到30至45 Mg/公顷范围内，可线性提高仙人掌梨的农艺性能。种植仙人掌梨的生物盐系统应采用定期补充ID和OM的组合使用方式，分别为每年304毫米和45 Mg/公顷。
