摘要
通过田间试验 ,按照井灌水稻生育阶段设置不同处理水平模式 ,通过不同模型分析选择 ,建立了适合三江平原地区井灌水稻的水分生产函数模型 ,并对敏感指数在全生育期内变化规律做进一步研究 ,为井灌水稻非充分灌溉条件下的灌溉制度优化提供基础依据。
According to the water conditions in each growing stage of rice in the well's irrigation area at Sanjiang Plain, the experimental treatments are designed. Through analyzing and selecting of different models. a water production function appropriated to Sanjiang Plain is established. At same time, the variable law of sensitivity index during the whole growing season of rice is studied. This result provides a scientific basis for optimum irrigation schedules of rice under the deficient irrigation.
