| 摘 要： | 为了准确检测纸膜覆盖对水稻植株蒸腾、地表蒸发和耕层渗漏的影响，本试验研制了盆栽条件下的水稻水分消耗检测系统，它由动态电阻应变仪、输出面板、计算机或万用表、土槽传感器、渗漏传感器、种植作物的土槽、水箱、漏斗、土槽，水箱配重、吊索和机架等组成。该系统的特点是，通过配重平衡了系统的静态质量，能对静态质量较大，但质量的动态变化值很小的质量变化动态系统进行实时检测，结构简单、造价较低。标定试验结果表明，研制的系统精度和灵敏度较高。该系统可以用于其他作物的水分消耗及其他类似质量动态变化系统的检测。

| Abstract: | In order to measure accurately the effect of paper mulching on the parameters of transpiration of rice plants, soil surface evaporation, and topsoil seepage, a water consuming test device for pot-grown rice plants was developed. The device was made up of a dynamic strain gauge, a fan-out, a computer or multimeter, an upper sensor, an underside sensor, a pot, a water tank, a hopper, two weight baskets, hanger ropes, and a framework. The characteristic of the device is that the static state weight of the system is balanced by the weight hasket. The device is suitable to measure the dynamic system, which with a big static state weight and a small dynamic value of the weight in time. The experimental results showed that the developed device possesses the advantage of high precision and sensitivity. The device with a sample structure and low cost can also be used to measure other pot planting dynamic systems in which the weight is looked as the variable. |
