我们试制一个土烘炉,用以测定土壤水分,经多次实践,性能良好,精确度较高.土烘炉热源用柴禾,砌炉用土块,取材容易,制作简单,适合于样板田蹲点和农村科学实验小组应用.一、土烘炉的砌制外壳用土块砌,炉顶用树枝支撑,草泥封盖,中间留一小孔,插温度表.炉底是一块铁板(一般炉盖即可).砌好后,内外都涂刷盐水,防止开裂. We trial a soil oven, used to determine the soil moisture, after many practices, good performance, high accuracy.Earth oven heat source with firewood, building furnace block, easy to extract, making simple, suitable for the model field stay And rural science experimental group application.A soil oven brick shell with soil, furnace roof with branch support, grass mud cover, leaving a small hole in the middle, insert the thermometer.The bottom of the furnace is a piece of iron (general furnace Cover can be.) After masonry, both inside and outside brushing brine to prevent cracking.
