Device used for radicula sampling and radicula growth monitoring and use method thereof

Abstract

The invention provides a device used for radicula sampling and radicula growth monitoring and a use method thereof. A radicula growth monitor is applicable to being buried in a selected soil positionfor repeated use, the device comprises a shell body, the shell body comprises a side wall and a bottom wall, containing space with generally consistent inner diameters from top to bottom is enclosed by the side wall, an upper opening of the containing space is opened wide, the bottom wall is arranged on a lower opening, and meshing openings are uniformly formed in the side wall and the bottom wall; the diameter of each mesh opening is >=2 millimeters and <=5 millimeters; the shortest distance between any two adjacent mesh openings is <=5 millimeters. The radicula growth monitor can overcome heterogeneity influences and reduce result differences caused by different inner and outer environments of the containing space to the largest extent, thereby detecting growth conditions of some area more objectively and accurately.

Description

technical field [0001] The invention relates to the technical field of plant root growth monitoring devices, in particular to a device for fine root sampling and fine root growth monitoring and a use method thereof. Background technique [0002] As the main organ for plants to absorb water and nutrients, fine roots are very important for maintaining plant growth. At the same time, as the main channel for soil carbon input, fine roots also play an important role in forest ecosystem functions. It is estimated that the annual net primary productivity of the underground part (mainly fine roots) in the forest ecosystem is greater than that of the aboveground part, and studies have shown that although fine roots account for less than 30% of the total biomass of forest tree roots, due to the rapid turnover of fine roots, Every year, carbon, nutrients and energy are returned to the soil through dead fine roots, even exceeding the litter above the ground. Studies have shown that wit...

Problems solved by technology

[0006] In view of the situation of the above-mentioned technologies, the present invention provides a device for fine root sampling and fine root growth monitoring, which is used to overcome the inability of the prior art to continuously obtain soil samples at a selected location at different time nodes, and cannot affect growth. Technical limitations of continuous physical, chemical and physiological monitoring of fine roots in this part of the soil sample
