North China Plain suffers from the world's most severe water scarcity and groundwater depletion due to intensive irrigation for agricultural production. It is imperative reduce consumption while safeguarding crop production food security. This study conducted a quantitative analysis with deficit strategies winter wheat using water-driven AquaCrop model. After model calibration validation field experimental data, we analyzed demand, yield, productivity (WP) of under various scenarios. A set optimal schedules were proposed different climate years, which significantly mitigated usage sustaining high yields WPs. The results indicated that despite demand future scenario was slightly higher than in historical period, their sensitive periods (reviving, jointing, flowering) remained same. Therefore, recommended adopting same periods. In wet 50% strategy only reduced by less 5% compared full irrigation, but it saved 1000–1100 m3 per hectare contributed WP 1.88 kg/m3. While normal dry an 25% could sustain over 96% maximum meanwhile save 650–800 m3/ha achieve almost as irrigation. These climate-smart adapting diverse climatic conditions largely mitigate maximizing use efficiency, are essential achieving precision sustainable management changing climate.

Subsoiling Before Wheat Sowing Enhances Grain Yield and Water Use Efficiency of Maize in Dryland Winter Wheat and Summer Maize Double Cropping System Under One-Off Irrigation Practice During the Wheat Season

Plants, Journal Year: 2025, Volume and Issue: 14(5), P. 738 - 738

The winter wheat and summer maize double cropping system is the primary pattern for in dryland areas of China. management tillage this typically conducted before sowing. However, few studies have validated quantified impact methods sowing irrigation practices during season on yield formation water use efficiency maize. Therefore, study hypothesized that subsoiling improves WUE by enhancing soil moisture retention plant development. A three-year field experiment with a two-factor split-plot design was at junction Loess Plateau Huang-Huai-Hai Plain China validation, from 2019 to 2022. Three (RT: rotary tillage; PT: plowing, SS: subsoiling) were assigned main plots, two growing (W0: zero-irrigation; W1: one-off irrigation) subplots. We measured moisture, grain yield, dry matter accumulation, nitrogen (N), phosphorus (P), potassium (K) results indicated increased storage maize, thereby promoting nutrient accumulation. Compared an average 19.5% 21.8%, respectively. One-off had negative effects pre-sowing productivity terms can mitigate these irrigation. Correlation analysis path model greater than season. most direct factor affecting whereas technique order preference similarity ideal solution (TOPSIS) comprehensive evaluation superior achieving high under practice These findings offer practical guidance optimizing drylands.

Suitability of agronomic water saving in karst areas and its enlightenment in the karst desertification control

Heliyon, Journal Year: 2024, Volume and Issue: 10(11), P. e32568 - e32568

Published: June 1, 2024

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.

Combined subsoiling and ridge–furrow rainfall harvesting during the summer fallow season improves wheat yield, water and nutrient use efficiency, and quality and reduces soil nitrate-N residue in the dryland summer fallow–winter wheat rotation

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Both subsoiling tillage (ST) and ridge furrow rainfall harvesting (RF) are widely implemented play an important role in boosting wheat productivity. However, information about the effects of ST coupled with RF during summer fallow season on productivity environmental issues remains limited. This study aims to explore water harvesting, productivity–yield traits, nutrient use efficiency quality, soil nitrate-N residue dryland winter wheat–summer rotation at intersection southern Loess Plateau western Huang–Huai–Hai Plain China 2018–2022. Three practices—deep plowing straw turnover (PTST), mulching (STSM), STSM (SRFSM)—are conducted season. The results indicated that practices significantly impacted residue. Compared PTST, enhanced by 7.0% 14.2%, respectively, as well N, P, K uptake 16.9%, 16.2%, 15.3%, thus increased grain yield 14.3% improved most parameters protein components processing albeit increase 0- 300-cm depth 12.5%. SRFSM, turn, led a further storage sowing, resulting 6.8%, internal 11.8%, 10.4%, 8.8%, 4.7%, thereby promoting 10.2%, improving contents all enhancing quality grain, simultaneously reducing layer 16.1%, compared STSM. In essence, this posits employing ridge–furrow (SRFSM) is promising strategy for yield, efficiency, within fallow–winter system.
