Review on Drip Irrigation: Impact on Crop Yield, Quality, and Water Productivity in China

The scarcity of freshwater resources is a global concern that exacerbated by an increasing population and climate change induced warming. To address this issue, the largest water-consuming sector has taken series measures termed as drip irrigation schemes. primary purposes are to reduce water near root zone, evaporation, decrease use. application scope getting wider wider, with number papers related year from 1990 2022. This study reviews crops planted in China had been irrigated equipment. effects technology on crop growth, physiology, quality, yield, use efficiency summarized. paper also provides overview development nitrogen uptake. Through meta-analysis, it found case shortage, can save ensure yield compared flooding irrigation, border furrow sprinkler micro-sprinkler irrigation. When amount more (100–120%), significantly increases yields 28.92%, 14.55%, 8.03%, 2.32%, 5.17% relative respectively. sufficient, improves yield. Moreover, researchers fertilizer leaching soil salinity. However, studies should be conducted future enrich research In conclusion, effective improving efficiency, reducing while decreasing salinity, making ideal solution issue resource globally.
