Water is the lifeline of agriculture and a precious, non-renewable resource. However, water pollution is becoming increasingly severe, and agricultural water usage is plagued by issues of high consumption and low efficiency. Rivers and lakes are frequently facing crises, and the sight of drying-up landscapes is becoming more common. These problems undoubtedly pose a serious threat to the development of the agricultural sector, necessitating urgent solutions to ensure sustainable water resource utilization and protect the sustainable development of agriculture
As the largest rice crop in China, with the highest yield and total output, its perennial cultivation area and total output account for about 28% and 40% of China's grain crops.

The application of water retention agents to combat soil and water loss on slopes is one of the most important tools. Water retention agent, also known as highly absorbent resin, super absorbent, solid water or polymeric absorbent, is a polymer with strong water absorption and water retention capacity made from a strong water absorbent resin. It can absorb a lot of water quickly and has the function of repeated water absorption. Absorption Water swells to hydrogel,it releases water slowly for seed germination and growing crops, thereby increasing soil water retention,improving soil structure, reducing deep water seepage and soil nutrient loss,and improving water utilization in greening project. Water holding agent is suitable for use in areas with low precipitation, irregular annual rainfall distribution and lack of irrigation water.

The name Super Absorbent Polymer was first translated from the Japanese, and the common international name is Super absorbent polymer (SAPs). Water retention agent was first developed in the 1960s by the U.S. Department of Agriculture Northern Research Institute using corn.

When it comes to "saline-alkali land", I believe most of you will think of a question like this reflexively:
Naturally sourced polymer-based hydrogels offer advantages over synthetic forms owing to their biocompatibility, physicomechanical and environmentally friendly properties.
