摘 要:植物树干生长量的实时精密测量可以用于观测植物生长情况,为此研制了一种植物树干生长量实时精密测量装置。首先设计了该装置的机械支架、各部分电路系统,并进行联调,完成整机制作。其次,在晴天、雨天、阴天3种不同天气条件下,以澳洲杉为材料,进行树木胸径日变化量的测量,并总结得到了周变化规律。结果表明,该装置能够实时精密测量植物树干生长量。Plant growth could be directly observed by real-time precision measurement of tree diameter. So the realtime precision measuring device for tree diameter was developed in this study. The mechanical bracket and circuit system of each part had been designed firstly,and the real-time precision measuring device was then completed.Then,the diameter of Araucaria heterophyll had been measured by this device during sunny day,rainy day and cloudy day,respectively. And the week change law of tree diameter was summarized. The results showed that this real-time precision measuring device could be well used for measuring tree diameter.
