一、土壤墑情監(jiān)測系統(tǒng)產(chǎn)品概述:
土壤水分貯存量及其變化規(guī)律的監(jiān)測,是農(nóng)業(yè)氣象、生態(tài)環(huán)境及水文環(huán)境監(jiān)測的基礎(chǔ)性工作之一。掌握土壤水分變化規(guī)律,對農(nóng)業(yè)生產(chǎn)、墑情監(jiān)測預(yù)測和其它相關(guān)生態(tài)環(huán)境監(jiān)測預(yù)測服務(wù)和理論研究都具有重要意義。Monitoring the soil moisture storage and its change rule, is one of the basic agricultural meteorology, environment and hydrology and environmental monitoring work. To grasp the change rule of soil moisture, all has the vital significance of service and theoretical study onforecasting soil moisture monitoring of agricultural production, and other relevantenvironmental monitoring and forecasting.
TYX-QTS1型土壤墑情監(jiān)測站采用的數(shù)據(jù)采集技術(shù),實時采集土壤剖面上各層的體積含水量,并進(jìn)行運(yùn)算和數(shù)據(jù)存儲。同時兼容不同測量原理的土壤水分傳感器,可根據(jù)不同層次的土壤的性質(zhì)來選用傳感器類型(FDR頻域反射技術(shù)或TDR時域反射技術(shù)),從而獲得更高的測量精度和重復(fù)性。TYX-QTS1 type soil moisture monitoring station by the data acquisition technology, real-time acquisition of the soil profile of each layer of the volumetric water content, and computing and data storage. Compatible with different measuring principle of soil moisture sensor at the same time, can be selected according to the nature of sensor types at different levels of soil (FDRfrequency domain reflectometry technique or TDR time domain reflectometry), so as to achieve the measurement accuracy and high repeatability.
