Embodiment 1

[0033] In this embodiment, the method of preventing the infiltration of precipitation by interception of micro-biological crusts in the arid desert area selects a natural complete dune with a crust thickness of 1.0-1.5cm for the test. Before the test, the soil water content of the dunes is measured here, which specifically includes the following steps. :

[0034] (1) Collect the pruned branches, and cut off the side branches to obtain the stick 100, and dry the stick 100.

[0035] (2) One end of the stick 100 is subjected to a hydrophilic diversion treatment, and the other end is subjected to a hydrophobic sterilization treatment to obtain a stick 100 having both a hydrophilic diversion end 1 and a hydrophobic sterilization end 2; at first, the hydrophobic sterilization treatment is carried out, and then Carry out hydrophilic diversion treatment, the specific treatment method is as follows:

[0036] (2-1) Preparation of hydrophobic bactericidal treatment solution: add azoxyst...

Abstract

The invention discloses a method for preventing infiltration of rainwater intercepted by micro-biological crusts in arid desert areas, comprising the following steps: (1) collecting pruned branches, cutting side branches to obtain sticks, and drying the sticks; (2) ) one end of the stick is subjected to a hydrophilic diversion treatment, and the other end is subjected to a hydrophobic sterilization treatment to obtain a stick having both a hydrophilic diversion end and a hydrophobic sterilization end; (3) inserting the hydrophilic diversion end of the stick downward In the formation, and the length of the hydrophobic sterilization end exposed to the ground is at least 5cm. The invention can effectively increase the water content of the sandy soil layer under the biological soil without damaging the biological soil in a large area.

Description

technical field [0001] The invention relates to the technical field of desert control. Specifically, it is a method for preventing infiltration of precipitation intercepted by micro-biological crusts in arid desert areas. Background technique [0002] Microbiological crusts are tiny drought-tolerant plants such as lichens, algae, and mosses that form a thick carpet-like shell on the sandy soil surface. The particles are tangled into agglomerates, which play a role in immobilizing the dust. [0003] However, with the deepening of research, it was found that although micro-biological crusts can play a role in sand fixation, it was also found that in areas with large areas of crusts, shrubs and other plants will gradually die, making it difficult for shrubs and other plants to grow. Survival in the crust area. The reason is that the micro-biological crust has a compact structure. After being saturated by precipitation, the precipitation will flow along the surface of the cru...
