Dual purpose stand and determination method for determining moisture physical property and percolation rate of forest soil

Abstract

The invention discloses a dual purpose stand for determining moisture physical property and percolation rate of forest soil. The stand comprises a clamping frame with a cutting ring, a tunnel for accumulating liquid, and a triangle stand; the upper edge of the tunnel for accumulating liquid is embedded below the clamping frame with the cutting ring, and the triangle stand is used for supporting combination of the clamping frame with the cutting ring and the tunnel for accumulating liquid. During usage, the cutting ring with soil which needs to be determined is placed on the stand, water is added to the height of the surface of the cutting ring for immersion, the cutting ring is taken and permitted to stand, and determination is respectively carried out according to determination standardsof forest soil moisture-physical property; the cutting ring composite set with soil whose percolation rate needs to be determined is placed on the stand, and determination is respectively carried outaccording to the soil percolation rate determination standard. The product is advantageous in that undisturbed soil particles in the cutting ring are not easy to fall off, standing of the cutting ringdoes not need dry sand, the cutting ring is directly placed on the stand, the volume is smaller, the product is simple and portable, interference due to human factors, such as multitime movement andthe like is avoided, operation is simple and practical as well as fast and convenient, and especially time for experiment determination in mass determination processes can be saved.

Description

technical field [0001] The invention belongs to the technical field of forest soil experiment equipment, and in particular relates to a dual-purpose bracket for measuring the moisture physical properties and infiltration rate of forest soil and a measuring method. Background technique [0002] Water is an essential nutrient for the survival and growth of plants and an indispensable element of the ecosystem. Soil water is one of the important components of the ecosystem. It not only affects the physical properties of the soil, but also the dissolution, transfer and The activities of microorganisms are closely related. The physical properties of forest soil moisture and soil infiltration rate directly affect the growth of forest vegetation, and the research on its water storage and soil conservation function is of great significance. Therefore, measuring the physical properties of forest soil moisture and soil infiltration rate is of great significance for implementing precis...

Problems solved by technology

In the process of soaking in water and placing it on dry sand, it is easy to cause soil particles to fall off and stick to some dry sand, which will affect the accuracy of the measurement

[0004] The forest soil infiltration rate is the determination of the forest soil infiltration rate issued by the State Forestry Administration (the forestry industry standard LY / T1218-1999 of the People's Republic of China), which stipulates the forest soil infiltration rate measured by the infiltration cylinder method and the ring knife method. The combination of the percolation cartridge and the ring knife bonded with melting wax is placed on the hanging funnel device. When we inject water, due to the influence of human operation, it is inevitable that the combination of the percolation cartridge and the ring knife will shake, causing unnecessary experimental error

And if the fixation is not stable, the combination of the percolation cartridge and the ring cutter will easily fall down, which will easily cause the experiment to fail
