摘要
开发了一套果树水分动态参数的测量系统 ,给出了该系统的硬件组成、软件设计和传感器的设计 ,以及该系统的测试试验结果。现场使用表明 ,该系统工作稳定 ,操作方便 ,省工省力。本文为研究果树的生理 ,找出其需水规律 。
A computerized dynamic instrument for water conditions of fruit trees was developed in this work. The operation principle, technical index and the design of hardware and software of microcontroller 89C51 were expounded. The instrument was used to measure the water conditions of a fruit tree, such as flow rate of transpiration sap, soil moisture, photon flux density, temperature and moisture in air, which was enabled to make long time, dynamic and on site measurement. It was characterized by advanced technique, multi function, high performance and easy operation. The dynamic instrument can offer powerful help in researching fruit tree physiology, finding the law of water requiring, as well as directing irrigation.
