【摘要】 计算机棉田信息采集与精量灌溉控制系统为研究滴灌条件下,棉田水分动态与棉花生长关系、棉田土壤盐分变化趋势、大气蒸散与不同时期棉田耗水关系而设计研制,为探索高产优质棉花需水规律提供了一种有效手段。主要介绍该系统的原理、各传感器(土壤水分、温度、土壤盐分、地下水位、降雨量、蒸发量)的功能及软件等。更多还原

【Abstract】 In order to study the relation between water dynamic in field and cotton growth, the varied trend of soil salinity, and the relation between atmospheric evaporation and water requirements in different time, a computer system for controlling irrigation and collecting information in cotton field was designed. It will be effective means to research evapotranspiration pattern of cotton that is high yield and good quality. This article introduced mostly principle of system, function of sensors (soil moisture, temperature, soil salinity, groundwater table, rainfall, evaporation) and frame of software.更多还原
