Summary
Seeping irrigation significantly improves soil conditions and crop yields compared to furrow irrigation. This water-saving technique enhances soil structure, accelerates crop maturity, and reduces disease and costs in greenhouses.
Area of Science:
- Agricultural Engineering
- Soil Science
- Agronomy
Context:
- Greenhouse cultivation relies on efficient irrigation methods.
- Traditional furrow irrigation presents challenges in water management and soil health.
- Optimizing environmental conditions is crucial for crop productivity.
Purpose:
- To compare the effects of seeping irrigation versus furrow irrigation.
- To evaluate impacts on soil properties, crop development, and water use efficiency.
- To determine the suitability of seeping irrigation for greenhouse environments.
Summary:
- Seeping irrigation increased soil water-stable granular by 81.4% and porosity by 29.0%, while decreasing bulk density by 21.2%.
- Soil temperature rose by 1.1-1.7°C, and relative air humidity decreased by 13.4% under seeping irrigation.
- This method saved 36.7% irrigation water, accelerated crop maturity, boosted yield, and reduced disease and production costs.
Impact:
- Seeping irrigation offers a superior alternative to furrow irrigation in sunlight greenhouses.
- The technique enhances soil quality, leading to improved crop growth and yield.
- Significant water savings and reduced disease incidence contribute to sustainable agricultural practices.
