The micro biological crust is a thick carpet-type shell formed on the surface of sandy soil by lichen, algae, moss and other small drought-enduring plants, and the microbial crust entangles sandy soil particles into clusters through rhizoids, hyphae, algae filaments and secretions thereof, thereby playing a role in fixing sand and dust.
However, with the progress of research, it is found that the micro-organisms can play a role in sand fixation, but it is also found that in areas with large-area skinning, shrubs and other plants die gradually, so that the shrubs and other plants are difficult to survive in the skinned areas. The reason is that the structure of the miniature biological crust is compact, and after the miniature biological crust is saturated by precipitation, the precipitation is lost along the runoff on the surface of the crust and cannot be effectively infiltrated, so that the precipitation is intercepted and cannot be infiltrated, and thus, moisture loss and evaporation are caused, deep moisture in sandy soil is deficient, and plant roots such as bushes and the like are gradually deficient in water and withered.
Because the biological ground skin has large area and is beneficial to sand stabilization, the large-area digging of the biological ground skin is not suitable for improving the water content of the lower layer sandy soil. Up to now, there is no method for effectively increasing the water content of biological sub-ground subsoil.

Comparative example 2
In the method for preventing the micro-scale biological crust interception precipitation infiltration in the arid desert area, a natural complete sand dune with the thickness of 1.0-1.5cm is selected for testing, and the soil water content of the sand dune is measured before the test, which specifically comprises the following steps:
(1) the pruned branches are collected, and the side branches are pruned to obtain the tree stick 100, and the tree stick 100 is dried in the sun.
(2) Carrying out hydrophobic sterilization treatment on the whole tree stick 100; the method specifically comprises the following steps:
(2-1) preparing a hydrophobic sterilization treatment liquid: adding azoxystrobin into ethyl acetate, stirring and mixing to obtain a solution A, adding methyl potassium silicate and benzalkonium bromide into water, and stirring and mixing to obtain a solution B; mixing the solution A and the solution B to obtain a hydrophobic sterilization treatment liquid; the volume ratio of the solution A to the solution B is 0.1: 1, the mass fraction of the methyl potassium silicate in the solution B is 10%, the mass fraction of the benzalkonium bromide is 1 thousandth, and the concentration of the azoxystrobin in the hydrophobic sterilization treatment liquid is 100 mg/mL.

(3) Inserting the lower end of the tree stick 100 into the stratum to a depth of 30cm, and exposing the upper end of the tree stick out of the ground to a length of 5 cm; the distance between adjacent sticks 100 is 1 m.
Carrying out artificial water spraying simulated rainfall according to the rainfall of 50mm, measuring the soil water content of a sandy soil layer 15cm away from the ground surface after 180 min, and showing the result: compared with the water content of the soil in the sand layer with the same depth without the tree stick, the water content is increased by 2.3 times.
After one year, the artificial water spraying simulated rainfall is carried out on the test areas of the example 1, the comparative example 1 and the comparative example 2 again according to the rainfall capacity of 50mm, and the soil water content at a position 15cm away from the ground surface is measured after 180 min, so that the results show that: compared with the corresponding stratum soil of the area without the tree stick, the water content of the test area in the example 1 is increased by 1.9 times; compared with the corresponding stratum soil of the area without the tree stick, the water content of the test area of the comparative example 1 has no obvious change; the test area of comparative example 2 showed only a 0.2-fold increase in water content compared to the corresponding formation soil in the area where no stick was inserted.
As can be seen from example 1, comparative example 1 and comparative example 2: the rainfall simulation is carried out when the tree stick 100 is just inserted, the soil water content increase amount at a position 20cm away from the ground surface is basically consistent, because a fresh gap exists between the tree stick 100 and the sand, the rainfall seeps along the fresh gap, and the three have no essential difference before.
After one year, in comparative example 1, since the sterilizing power of the tree stick 100 is very weak (calcium propionate decomposes propionic acid only under acidic conditions and has a strong sterilizing effect and very weak killing power against moss, algae, etc.), the damaged crust around the tree stick 100 grows again, so that the gap between the tree stick 100 and the ground surface is blocked, precipitation is difficult to smoothly infiltrate along the gap between the tree stick 100 and sand, and the tree stick loses the effect of improving precipitation infiltration. In the comparative example 2, azoxystrobin has good capability of killing fungi, and the benzalkonium bromide not only has good sterilization capability, but also can kill and inhibit plants or organisms such as moss, algae and the like, so that the crust around the tree stick 100 on the ground surface can not grow densely, and the azoxystrobin and the benzalkonium bromide on the tree stick 100 diffuse into the crust 200 on the ground surface, thereby further enlarging the area of rapid infiltration of rainfall around the tree stick 100 and being beneficial to infiltration of the rainfall; however, as time goes on, the interval between the tree stick 100 and the sandy soil layer in the stratum becomes gradually compact, and the hydrophobic effect of methyl potassium silicate is mainly caused by the reaction with carbon dioxide, compared with methyl sodium silicate, it is more difficult to form a hydrophobic membrane by the reaction of silanol groups in the molecular structure thereof with silanol groups on the surface of sandy soil, so that it is not favorable for the rapid vertical infiltration of precipitation along the gap around the tree stick 100 under the guiding effect of the tree stick 100, and the rapid lateral infiltration is mainly after precipitation vertically infiltrates along the tree stick 100 from the ground surface and crosses the cortex, so that the scheme in comparative example 1 is not favorable for increasing the water content in the sandy soil layer below 10cm from the ground surface. The technical scheme of example 1 well overcomes the disadvantages of the technical schemes of comparative example 1 and comparative document 2, and includes that firstly, one end of the tree stick 100 is subjected to hydrophobic sterilization treatment, and then the other end of the tree stick 100 is subjected to hydrophilic diversion treatment, so that when the hydrophilic diversion end 1 is prepared, the hydrophobic sterilization end 2 is exposed in the air for a long time, carbon dioxide in the air reacts with methyl potassium silicate to form a layer of hydrophobic waterproof film doped with azoxystrobin and benzalkonium bromide on the surface of the wood stick 100, the retention time of the azoxystrobin and benzalkonium bromide on the hydrophobic sterilization end is greatly prolonged, the effects of sterilization of azoxystrobin and benzalkonium bromide or benzalkonium bromide, killing plants and organisms such as moss and algae can be fully exerted for a long time, the biological crust of the attachment of the tree stick 100 can be damaged along with the prolonging of time (as shown in fig. 2), and a biological crust breaking area 300 (as shown in fig. 2) is formed around the tree stick 100, thereby enlarging the effective area around the tree stick 100 where precipitation rapidly infiltrates. The hydrophilic diversion end 1 is covered with a layer of mixture of sodium methyl silicate and calcium propionate, silanol groups in a molecular structure of the sodium methyl silicate can perform a dehydration crosslinking chemical reaction with silanol groups on the surface of sand particles to generate a water-insoluble macromolecular waterproof compound, so that a hydrophobic organosilicon resin film is formed on a sand ground layer around the tree stick 100 to reduce horizontal penetration of precipitation and promote vertical penetration depth, and the doped calcium propionate can form holes on the organosilicon resin films to facilitate partial horizontal penetration of the precipitation along the vertical infiltration process of the tree stick 10, so that the precipitation can be rapidly vertically infiltrated along the tree stick under the diversion effect of the tree stick and also partially horizontally penetrated, vertical infiltration of the precipitation is ensured, horizontal penetration of the precipitation is also considered, and the water content in the depth of 10-20cm from a biological cortex is effectively improved.
