调亏灌溉下旱稻产量性状与作物灌溉水量模型的研究

Study on Model of Production of Upland Rice and WaterIrrigation Amount under RDI

对调亏灌溉旱稻产量性状试验数据进行了分析研究,建立产量、千粒质量、有效穗、穗粒数与作物3阶段灌溉水量之间的统计回归数学模型,找出对产量、千粒质量、有效穗、穗粒数有显著影响的变量。建立了一级模糊概率综合评判模型,确定理论上满意的旱稻节水灌溉技术方案并进行综合评判,这对探索旱稻亏缺节水灌溉规律,提出一种节水效率较高、经济效益较好的生物工程节水技术具有重要的现实意义。

In this paper,test data obtained from the research on upland rice yield under RDI is firstly analysised.To identify variables that has a significant impact on production,grain weight,effective ear,grains per spike,the statistical regression model is established between production,grain weight,effective ear,grains per spike and the irrigation water amount of three stages of crop.Secondly,the establishment of a fuzzy evaluation model is to determine theoretically the satisfied water-saving irrigation technology program of upland rice and conduct a comprehensive evaluation.it has important significance to explore the law of water-saving irrigation of upland rice,it is also significant to propose the bio-engineering water-saving technology.
