云南松根系对土壤牵引效应测试系统的设计与实现

目前在野外对云南松根系与土壤的机械效庆的研究，由于测试研究受多种因数的影响，开展研究困难较大，研究精度也受到一定程度的影响，这对较深入的描述根系与土壤相互作用的机械效应带来一定的困难。本文基于这一实际，设计了能在室内和野外进行实时测试分析的测试系统，并配套了支持PCMCIA插槽的DAQP－12型模数转换（A／D）卡，以及直流电供电的QT－300型调理装置。结合所配套的硬件，利用Visual C在Windows95/98平台编写了软件，经过实际试验测试，系统各项性能能够满足云南松根系对土壤的机械效应研究的测试分析要求。

Design and Realization of the Test System on Mechanical Effect of Yunnan Pine Root and Soil

The research of mechanical effect on Yunnan pine root and soil at field presently, owing to been influence of multi-factor on test and research. It is more difficulty to be researching. The precision of study has been influence of extent to a certainly. It is more difficulty to describe in-depth mechanical effect on Yunnan pine root and soil. This paper is based upon the fact. We designed a test system which can test data at real time on room and field, and it's correspond to hold out PCMCIA stick of A/D conversion block ,and suit well device QT-300 by DC power supply. Windows 95/98's application software has been compiled by Visual C to combine with hardware. The system has been tested variedly, its capability can meet the need of test and analysis for mechanical effect on root and soil.
