The special "dual" hydrogeological structure in karst areas causes rainfall easily "leaking" into the ground, resulting a unique "karst drought". In these areas, drought and insufficient water resources seriously restrict sustainable development of agriculture. order to restore ecology desertification, develop ecological industries, improve utilization efficiency resources, advance water-saving agriculture such literature review method was applied discuss suitability agronomic measures areas. results are as follows. (1) Agronomic including tillage, mulching, water-fertilizer coupling, chemical regulation, crop allocation deficit irrigation can all enhance WUE. For example, deep tillage loosening increased WUE by 15.1% 15.9% respectively. spring wheat under straw mulching 17.17% ∼ 43.01% compared with that film. Increased density intercropping corn saved 9.85% water. (2) cultural or natural particularity limits application therefore choices adjustments necessary according local conditions: ① No should be adopted because high output labor force; ② need crushed; ③ coupling fertilizer reaches better effect when crops several hours before rainfall; ④ shallow soil layer complexity preparing retaining agent make it unsuitable use agent; ⑤ agroforestry dwarf dense planting is more suitable; ⑥ carried out using small pools. Based on above results, proposes offered following. First, construct optimal model regional apply composite measures. Second, suggested establish coordinating forest, grain grass, vigorously ecologically derivative agroforestry. Third, there necessity strengthen research technology about leakage monitoring resistance, intensify studies "five waters" transformation at basin scale. implication an important reference for developing agriculture, solving shortage agricultural ensuring sustainability improving farmers' living standards.

To improve cotton yield in salinized arid fields, excess salt is removed and phosphorus content increased. Adjusting phosphate fertilizer timing with water reduces binding calcium ions. Salt removal precedes application, enhancing soil availability promoting better growth. However, the optimal time for delaying drip irrigation remains unclear. Therefore, this study evaluated total salt, available phosphorus, under condition of delayed application. We conducted a field experiment using completely randomized design to adjust phosphatic application apply same amount pure phosphorus. Specifically, “t” was defined as duration one cycle, starting points were follows: T1, 1 h; T2, h + 1/3 t T3, 2/3 CK, h. These values represent leaching through each treatment. Phosphate applied after washing complete. The results revealed that T2 treatment exhibited highest SPAD value (64.53), which 11.46% 15.48% higher than T1 T3 treatments. 0–20 20–40 cm layers had pH 9.12 9.37, representing increases 1.93%, 1.21%, 4.50%, 1.38% compared treatments, respectively (p < 0.05).

To clarify whether light frequent (LF) irrigation under same or reduced amount beneficial achieve this goal, further tap saving potential. Based on drip conditions, three–year (2020–2023) field experiment was conducted investigate effect four treatments (CK, conventional at jointing anthesis stages; LF1, 100 % ETc, ETc evapotranspiration; LF2, 75 LF3, 50 ETc) yield, consumption characteristics, leaf photosynthetic physiology grain filling process. The results showed that compared with CK, LF1 LF2 significantly increased rate chlorophyll content flag leaves 18 days after anthesis, promoted filling, finally enhanced dry matter accumulation 1000–grain weight (TGW) yield. LF management mode also deep soil (1.4–2.0 m), evapotranspiration, improved WPc productivity. However, did not have significant enhancement wet year, but had one less than normal year. achieved highest three years (2.1 kg m–3), 25 (37.5 mm) 40 (60 years, respectively.
