5,000-Mu Cotton Field Drip Irrigation Filtration System Project in Xinjiang

## Project Background Xinjiang is China's largest cotton production base, and cotton cultivation is the pillar industry of local agriculture. A regiment farm of the Xinjiang Production and Construction Corps plants 5,000 mu of cotton, using groundwater drip irrigation. Due to the high sand content in local well water and the poor filtration effect of the original filtration equipment, the emitters of drip irrigation tapes were frequently clogged, resulting in poor irrigation uniformity and severely affected cotton yield. The leadership of the regiment farm decided to carry out a comprehensive upgrade and transformation of the irrigation filtration system. ## Solution Henan Haojun Agricultural Technology Co., Ltd. designed a three-stage filtration system scheme based on the well water quality test report of the regiment farm and the cotton drip irrigation requirements: ### 1. First-stage filtration - Centrifugal filter - Equipped with 4 units of LZHS 4-inch plastic centrifugal filters - Efficiently separates sediment particles in well water, with a sand removal efficiency of 92%-98% - Consumable-free design, low operating cost ### 2. Second-stage filtration - Sand filter - Equipped with 2 sets of automatic backwash sand filters - Deep filtration with quartz sand, effectively removing fine suspended solids and organic matter in water - Automatic backwashing, no manual operation required ### 3. Third-stage filtration - Fully automatic backwash disc filter - Equipped with 1 set of LZHS H-type 4-inch 8-unit fully automatic backwash disc filtration system - The total system flow rate is 320 m³/h, meeting the simultaneous irrigation demand of 5,000 mu of cotton - Filtration precision is 120 mesh, ensuring no emitter clogging - Dual control of pressure difference + timing, fully automatic operation ### 4. Supporting equipment - LZHS hydraulic control valves (pressure reducing valves, pressure sustaining valves, pressure relief valves) - Intelligent irrigation controller, supporting zoned rotational irrigation - Venturi fertilizer applicator, realizing integrated water and fertilizer management ## Project Implementation The project completed installation and commissioning before cotton sowing in Xinjiang: - Equipment production: 20 days - Logistics transportation: 7 days (from Zhengzhou to Xinjiang) - On-site installation: 10 days - Commissioning and training: 3 days Technical personnel of Haojun Agricultural provided on-site installation guidance, and conducted training on system operation and maintenance for the staff of the regiment farm's water conservancy station. ## Project Results The system operated stably throughout the entire cotton growth period, achieving remarkable results: 1. **Significant reduction in emitter clogging rate**: Dropped from the original 30% to below 2% 2. **Improved irrigation uniformity**: Increased from 78% to 93% 3. **Obvious water-saving effect**: About 50 cubic meters of water saved per mu, with a total of 250,000 cubic meters of water saved throughout the season 4. **Yield increase**: Cotton yield per mu increased by about 8%, bringing significant income growth to the regiment farm 5. **Simple operation and maintenance**: Fully automatic operation, no need for frequent manual cleaning of filtration equipment ## Customer Feedback "The filtration system of Haojun Agricultural has excellent quality and stable operation, which completely solved our long-standing problem of emitter clogging caused by sand in well water. The technical personnel provided professional and considerate services with thorough training, and our staff quickly mastered the operation methods. This system not only improves irrigation efficiency but also saves a large amount of water resources. It is truly a good equipment that benefits farmers." —— Director of the Water Conservancy Station of a regiment farm of the Xinjiang Production and Construction Corps --- *Henan Haojun Agricultural Technology Co., Ltd. has focused on agricultural irrigation filtration equipment for 14 years, providing professional filtration system solutions for large farms in northwest China such as Xinjiang, Inner Mongolia, and Gansu.*
