Device for measuring three-phase ratio of soil and method for measuring three-phase ratio of soil through device

Abstract

The invention relates to a device for measuring the three-phase ratio of soil and a method for measuring the three-phase ratio of soil through the device. The device comprises an annular cutter, an oven, a U-shaped pipe and a measuring cylinder. A sealing upper cover and a sealing lower cover are arranged on the annular cutter. The annular cutter is arranged in the oven. The U-shaped pipe is arranged outside the oven and full filled with water. A guide pipe I is arranged between one end of the U-shaped pipe and the sealing upper cover of the annular cutter and communicated with the inner portion of the U-shaped pipe and the inner portion of the annular cutter. A guide pipe II is arranged at the other end of the U-shaped pipe. One end of the guide pipe II is communicated with the U-shaped pipe, and the other end of the guide pipe II extends into the bottom of the measuring cylinder. The device has the advantages of being easy and convenient to use, accurate and the like, is particularly suitable for measuring the index, namely, the three-phase ratio of soil of soil samples of different types of texture, and is capable of making the index, namely, the three-phase ratio of soil, widely applied to the scientific research work of soil.

Description

technical field [0001] The invention belongs to the technical fields of agriculture, forestry and horticultural production, and in particular relates to a device for measuring soil three phases and a method for using the device to measure soil three phases. Background technique [0002] Soil is an essential element in agriculture, forestry and horticulture. In 2008, my country's modern corn industry technology system investigated the farmland soil in each major corn producing area in the country, and found that the deterioration of the soil quality of the plow layer has become the main obstacle affecting my country's corn production capacity. [0003] Focusing on the goal of improving the soil quality of the plow layer, agricultural researchers at home and abroad have carried out a lot of research work. Zeng Dechao conducted research on the three-phase comparison of farmland soil earlier, and believed that the soil is composed of three substances: solid phase, liquid phase,...

AI Technical Summary

Problems solved by technology

However, the current method for measuring the three phases of soil is relatively cumbersome, especially when it involves the measurement of soil density, and the system error is relatively large, which limits the application of this index in the field of farmland soil physical properties research.
