Tianjin Agricultural Machinery Research Institute: Pilot demonstration of soil hot water disinfection technology

Recently, the Tianjin Agricultural Machinery Research Institute’s project team of “Integrated Planting Pests and Diseases Comprehensive Control Technology and Equipment Demonstration and Promotion” undertaken by the Tianjin Agricultural Machinery Research Institute carried out soil hot water in two demonstration sites in Hexiwu Town, Wuqing District and Xinkou Town, Xiqing District. Demonstration of disinfection technology.

The soil hot water disinfection treatment technology is to directly water the hot water above 75 °C through the drip irrigation pipe to the soil of 0-30 cm to kill various pathogens and root-worms. Soil hot water disinfection operations are not subject to seasonal restrictions (the best results in summer), and soil compaction and plant growth disorders do not occur, reducing the pollution of pesticides on soil and vegetables.

The introduction of demonstration soil hot water disinfection technology and equipment is one of the main contents of the project. In the next step, the project team will collect various data in the trial, summarize, analyze and improve the soil hot water disinfection technology to ensure that the project implementation achieves the expected results.
