Single irrigation volume 30 cubic meters/hectare 25 cubic meters/hectare -17%
Vegetable yield 8 tons/hectare 9 tons/hectare +12.5%
Moisture Utilization 65% 80% +15%

The FutureDevelopment direction

  1. Multifunctionalization: The future reactive gel catalyst will not only have water-saving functions, but may also integrate various functions such as fertilizer slow release, pest control, etc., to further improve the comprehensive benefits of agricultural production.
  2. Intelligent: In combination with IoT technology, an intelligent irrigation system is developed to monitor soil moisture and plant water demand in real time, automatically adjust the release rate of gel, and achieve precise irrigation.
  3. Environmental Materials: Develop more environmentally friendly reactive gel catalysts to reduce negative impacts on soil and the environment, and promote sustainable agricultural development.

Conclusion

Reactive gel catalysts exhibit significant water-saving effects in modern agricultural irrigation systems, which not only reduces waste of water resources, but also improves crop yield and quality. With the continuous advancement of technology, its application prospects in agriculture will be broader. Through rational use and continuous innovation, reactive gel catalysts are expected to become an important part of future agricultural water-saving technologies.
