普通水银温度表测量农田温度,不但安装、测量和使用不便,而且进入田间测量破坏了田间自然状态,不能客观地反映农田的真实状况,而类似的医用单测头点温表,又难以对农田作物小气候的微小差异(如微气象梯度观测,农田不同处理的对此试验等)及平均状况作确切的描述。在农田,农田小气候梯度观测,保护地栽培,粮库、温室,塑料膜膜复盖和各种科学实验中,为了不破坏自然状态,其实地反映出该状态下温度的分布及其微小变化,需要进行隔测。同时,结合农用仪器要求准确,可靠、简单、轻便、成本低的特点,试用半导体来测温。
Ordinary mercury thermometer to measure farmland temperature, not only the installation, measurement and use of inconvenience, but also into the field measuring the destruction of the natural state of the field can not objectively reflect the true state of farmland, and a similar medical single probe point temperature table, but also difficult to farmland Small differences in crop microclimates (eg, micrometeorological gradient observations, tests of different treatments in the farmland, etc.) and the average status are accurately described. In order to avoid damaging the natural state in farmland, microclimate gradient observation of farmland, cultivation of protected areas, grain storage, greenhouse, plastic film and other scientific experiments, in fact, the temperature distribution and slight changes in this state are reflected, Need to carry out testing. At the same time, with the requirements of agricultural instruments accurate, reliable, simple, lightweight, low cost features, try the semiconductor temperature.
