Abstract

The invention discloses a device for determining field moisture capacity of soil with different particle sizes indoors. The device comprises a soil sample glass container (1), wherein one side of the surface of an iron stand (3) is provided with a column in the position near the edge, and the column is provided with a big iron ring (5); the soil sample glass container (1) is vertically arranged in the big iron ring (5); a big beaker (4) is arranged on the surface of the iron stand (3), and the upper opening of the big beaker (4) is faced with the bottom of the soil sample glass container (1); and the bottom of the soil sample glass container (1) is provided with a plastic bottom cover (2), thereby solving the problem of laboratory determination of field moisture capacity of soil with different particle sizes.

Description

technical field [0001] The invention relates to a device and method for indoor determination of field water holding capacity of soils with different particle sizes, in particular to a method for measuring the field water holding capacity of soil samples with different particle sizes by natural air-drying, grinding and wet sieving, and then drying according to different particle sizes. A water holding capacity device belongs to the technical field of soil science. Background technique [0002] Soil moisture has long been an important research content of ecosystems such as fields, grasslands, and forests, especially in arid and semi-arid regions that account for about 1 / 3 of the world's land, where the preservation and utilization of soil moisture is particularly important. Soil moisture is an important indicator of dryness and crop wilting in agricultural research areas, and an important parameter for farmland irrigation management, regional hydrological conditions research a...
