基于虚拟仪器的番茄水胁迫中心频率的研究

选择番茄作为研究对象,采用多学科基础理论与虚拟仪器实验相结合,分析受不同程度水胁迫时,番茄的声发射检测频率波动范围,从而获取中心频率并确定与之相对应的频率幅度。结果表明,对中心频率的分析可以用来确定番茄植株受水胁迫的程度,并从无损检测角度为实施精准灌溉提供了理论依据。

Study on center frequency of tomato water stress based on virtual instrument

In this research, tomatoes were chosen as researching object, combining virtual instrument experiment with many kinds basic subjects theory. By analyzing audio emission which was detected frequency range of tomato under different water pressing extent, the center frequency with confirming against frequency amplitude was obtained. It proved that by analyzing the center frequency, the extent of stress that was imposed on tomato plant from water could be confirmed. It provided theory to exact irrigation from t...
