【摘要】 根据土壤-作物-大气连续体(SPAC)理论,水分在连续体内的运动主要由水势差决定。准确测定农田水势对于实施精准灌溉十分重要。文章介绍了基于农作物微环境信息采集与处理,通过混合软测量模型整体估算农田水势的新方法。更多还原

【Abstract】 In accordance with the theory of Soil-Plant-Atmosphere Continuum(SPAC)t,he motion of moisture in the continuum is decided chiefly by the water potential differenceF.or the implementation of precision irrigation(PI)i,t is most important to measure precisly farmland water potential.A new method estimating farmland water potential based on information collection and procession of tiny environment for farmland crops is introduced.更多还原
