土壤含水量预报现状综述

Soil Moisture Content Prediction Situation Review

土壤含水量是土壤自身组成物质之一,是农作物生长发育的基本条件,也是田间节水灌溉的技术基础。精确预报土壤含水量的变化,对适时调节灌溉额度,保证作物优质生长具有重要意义。为此,对国内外关于土壤墒情预测研究的一些理论模型进行了总结,重点阐述了现有土壤墒情预测采用的主要类型和基本原理、各自适用的条件以及各模型应用的不足,并指出了土壤墒情预报研究的发展趋势。

Soil moisture content is one of the material of soil, is the basic condition of crop growth and development, also is the base of water-saving irrigation technology, it is important to precisely forecast the change of soil moisture content for timely regulating irrigation quota and guaranteeing quality crop growth. This paper summarizes the some of the theoretical model of the soil moisture prediction research at home and abroad about, focuses on soil moisture prediction of the main types, basic principle, applicable condition and the model of the shortcomings of the application, and points out that the soil moisture forecast the trend of the development of research.
