Soil seed bank germinating device and using method

Abstract

The invention relates to a soil seed bank germinating device and a using method. The soil seed bank germinating device comprises a tray, sponge and a germinating disc; the sponge for absorbing water is placed in the tray; the germinating disc is arranged on the sponge and is used for holding soil used for detecting a soil seed bank; a plurality of through holes are formed in the bottom surface, in contact with the sponge, of the germinating disc and are used for diffusing the water in the sponge upwards to the soil in the germinating disc.

Description

technical field [0001] The invention relates to the technical field of agricultural experiment devices, in particular to a soil seed bank germination device and a method for using it. Background technique [0002] The soil seed bank refers to the sum of all viable seeds in the soil and the fallen leaves on the soil surface, which is the material basis for the regeneration of plant communities. Identifying the types and quantitative characteristics of these seeds is a key issue in many related disciplines such as plant community and restoration ecology. important content. [0003] One of the key technologies in the research process of soil seed bank is the determination of the number of species and the identification of species. There are two commonly used methods for species identification: one is to directly separate the weed seeds from the soil, and then count them, that is, the physical separation method (or called direct statistical method), this method includes elutria...

Problems solved by technology

[0005] In order to improve the deficiencies of the prior art, the object of the present invention is to provide a soil seed bank germination device and its use method, to solve the existing in the prior art panning method and floating method to spend a lot of manpower and material resources, and inaccurate; The operation time of the seed germination method experiment is too long, and when the soil surface is replenished with water during the experiment, it is easy to cause soil compaction and damage the flatness of the soil surface, and even small seeds will be washed out of the soil layer, affecting seed germination, and sand is laid on the bottom It is difficult to control the thickness of 1-2cm when the matrix is ​​stirred, and it is easy to stir the matrix such as the lower layer of sand, which will eventually cause technical problems such as reduced repeatability of the experiment.
