Embodiment 1

[0018] Embodiment 1: Sampling device for collecting biocrust soil grinding slices

[0019] The sampling device used to collect biocrust soil grinding slices is a triangular prism with a height of 5 cm and a side length of 3 cm. Two layers of one side are overlapped and folded in half; by selecting a plastic plate with hardness and elasticity and a thickness of 0.5-1 mm, cut Grow a 9cm by 5cm wide strip of plastic, then fold it into a triangular shape, forming two overlapping folds on one side of the opening.

Embodiment 2

[0020] Embodiment 2: Sample storage device for fixed collection of biocrust soil grinding slice sampling device

[0021] Select a plate with a length of 20 cm, a thickness of 8 cm, and a multiple of 19.5 cm wide as the storage device base of the device for collecting biological crust soil grinding slices, and take out some rectangular grooves in it as sample grooves, and the groove length of each sample groove is 14cm, width 2.5cm, depth higher than 5cm, lower than 8cm, the distance between the sample grooves is 3cm, used to place and fix the device for collecting biological crust soil grinding slices.

Embodiment 3

[0022] Embodiment 3: The application method of the sampling device for collecting biocrust soil grinding slices in the field

[0023] Spray the biocrust soil sample to be collected, and the spraying humidity should be such that the soil sample does not disperse after collection, and then insert the prepared above-mentioned grinding slice sampling device for collecting biocrust soil into the soil layer vertically until Stop when the surface layer of the sample is 2cm away from the top of the sampling device. Gently pinch the top of the sampling device and pull it out. It does not enter the 2cm part of the soil layer. The slight shrinkage of the sampling device will make the soil samples collected in the sampling device completely taken out together with the sampling device; After taking out the samples, seal the bottom of the sampling device with scotch tape to prevent the sand from flowing out; put them into the sample tank of the sample storage device after numbering, and alte...

Abstract

The invention discloses a device used for collecting biological crust soil layers, and applications thereof in the wild. In one embodiment, the device for collecting samples is a triangular prismoid having a height of 5cm and a side length of 3cm, wherein one surface of the triangular prismoid is composed of two overlapped layers; and the device is made by a sheet of plastic board having a thickness of 0.5-1mm. The plastic board is cut into plastic strips having a length of 9cm and a width of 5cm, and each plastic strip is folded into a triangular prismoid, with the surface of the opening side composed of two overlapped layers. Another embodiment is a storage device for the sample-collecting device. Planks having a length of several times of 20cm, a thickness of 8cm and a width of 19.5cm are used as the pedestal for the storage device. A plurality of rectangular grooves are made inside the pedestal as sample grooves, each sample groove has a length of 14cm, a width of 2.5cm and a depth of more than 5cm and less than 8cm, and the space between the sample grooves is 3cm. The sample collector and a method for wild operation are successfully designed in the invention, which ensure the integrity of the biological soil crust, prevent the separation of the crust layer and soil of the lower layer, and can be applied in various fields.

Description

field of invention [0001] The present invention relates to the technical field of soil biology, in particular, the present invention relates to a device for collecting biocrust soil grinding slices and the technical field of application in the field. Background technique [0002] In recent years, my country's desertification has become more and more serious, and it is one of the countries with the most serious desertification in the world. The total area of ​​desertified land has reached 3.73 million square kilometers, and the annual expansion rate is 2460 square kilometers. The annual direct economic loss due to desertification is as high as 540 million billion. In view of this serious situation, it is urgent to find an effective way to prevent the desertification of land resources. [0003] As a product of the special environment in arid desert areas, biological crusts are organic complexes formed by bryophytes, bacteria, fungi, blue-green algae, lichens and soil. In the ...
