Agriculture The occurrence of waterlogging is due to excessive precipitation, farmland soil moisture in a wet or saturated state, soil pores filled with water, lack of air, resulting in Plant roots environmental conditions deteriorate, growth and development, resulting in crop reduction or quality reduction. In order to standardize and strengthen the farmland waterlogging meteorological level forecasting and alarm service business, it provides scientific basis for agricultural disaster prevention and mitigation. standard. Farmland waterlogging weather rating1 ScopeThis standard specifies the level of waterlogging in the farmland. This standard applies to farmland waterlogging weather forecast, early warning services and related research.2 terms and definitionsThe following terms and definitions apply to this document. 2.1 Farmland waterlogging Soil water content in the farmland is too wet or saturated, the soil is filled with large pores, lack of air, resulting in deterioration of the environmental conditions of the plant roots. An agricultural weather disaster that leads to crop reduction or quality reduction. 2.2 Soil field water holding capacity The soil can keep the capillary water with the maximum water content. Note. Percentage (%) of moisture quality in the same volume or in the same quality soil. [GB/T 20481-2006, definition 2.9] 2.3 Soil relative humidity relativesoilmoisture The ratio of actual soil water content to soil water holding capacity. Note. expressed as a percentage (%).
