江苏如皋市农田水利试验站的试验技术人员为了给节水灌溉提供科学的依据,确保水稻高产、稳产,对水稻耗水量进行了多年的观测试验,掌握了水稻耗水量的一般规律,找出了影响水稻耗水量的主要因素,建立了水稻耗水量和光、温、水等主要气象要素的数学模式,并考虑未来天气趋势、土壤性质等诸多因素的综合作用,科学地确定水稻的灌溉水量。
In order to provide a scientific basis for water-saving irrigation, the experimental technicians in Jiangsu Rugao Farmland Water Conservancy Experimental Station have ensured the high yield and stable yield of rice and have conducted many years of observational experiments on the water consumption of rice, mastered the general law of rice water consumption and found out The main factors influencing water consumption of rice were established, and the mathematical models of rice water consumption, light, temperature, water and other major meteorological elements were established. Taking into account the combined effect of future weather trends, soil properties and many other factors, the irrigation water quantity of rice was scientifically determined.
