Method for sand-fixing, water preserving, planting grass and tree afforestation desert

A grass seed and desert technology, applied in the fields of botanical equipment and methods, land preparation methods, plant protection, etc., can solve problems such as the speed of treatment cannot keep up with the speed of desertification, the inability of plants to provide a growth environment, and the lack of fundamental containment. The effect of plant survival rate and growth rate, improving desert ecological environment, and avoiding planting soil loss

Problems solved by technology

Although people from all walks of life pay more and more attention to the cause of desertification prevention and control, and spend a lot of money on desertification prevention and control, overall, the speed of governance has not kept up with the speed of desertification, and the trend of partial improvement and overall deterioration continues. The situation of people retreating has not been fundamentally contained
[0003] The existing method of desert control mainly adopts the method of building windbreaks, but this method requires a lot of investment, slow results, long cycle, difficult follow-up management, and cannot directly prevent desert water evaporation and sand loss, so the effect is not great
People have also proposed the use of spray film, liquid mulch film, spraying nutrient solidified water, activator and other methods to control deserts, but these methods can only work in a short period of time and cannot provide a suitable growth environment for plants for a long time
[0004] The inventor disclosed in the Chinese invention patent applications 02130859.4 and 03113631.1 the method of using artificial grass to cover the desert, to a certain extent, to collect the evaporated groundwater, which has a certain effect on planting grass and trees, but the collected water is dispersed under the artificial grass , cannot gather under the planted plants for plant absorption
The mesh bag used to hold the soil is too large, and the soil containing organic fertilizers is easily moved by wind, sand, rain and soil movement, resulting in the lack of soil for the planted plants, resulting in plant death

Embodiment 1

[0022] Such as figure 1 As shown, adopt the method of the present invention to control the desert and at first utilize the small sand dunes 1 naturally formed on the desert surface, if some parts are too flat, then artificially move the sand slightly to form a small sand dune with a height of 10 to 50 centimeters and an area of ​​1 to 2 square meters . Then lay the simulated lawn on the desert surface, compress and fix the simulated lawn 4 with umbrella nails, so that the simulated lawn on the top of the small dune is slightly higher than the simulated lawn around it.

[0023] Drilling machines such as small drills are used to drill and measure the groundwater level and content at the top of the small sand dune 1 to obtain water-containing soil. The drilling hole is also used as a planting hole for planting plants. Planting holes were excavated on top of the remaining small dunes not used for drilling.

[0024] Measure the distance between the aquifer and the simulated lawn,...

Embodiment 2

[0029] Utilize the wavy sand dunes 5 naturally formed on the desert surface, and artificially move the sand and soil slightly to form wavy sand dunes in areas that are too flat (such as figure 2 shown), then lay the artificial turf 4 on the desert surface, compress and fix the artificial turf with umbrella nails, so that the artificial turf at the top of the small sand dunes or wavy sand dunes is higher than the artificial turf around it.

[0030] Drilling machines such as small augers are used to drill and measure the groundwater level and content on the top of small sand dunes or wavy sand dunes, and obtain water-containing soil. The drilling holes are also used as planting holes for planting plants. Planting holes are formed by excavating at intervals of 1 to 3 meters at the top of the remaining small sand dunes or tops of wavy sand dunes not used for drilling.

[0031] Measure the distance between the aquifer and the simulated lawn, select various lengths of water-absorbi...

Abstract

The method of afforesting desert includes spreading simulating grass onto the surface of desert, measuring underground water content and obtaining water containing soil, digging planting hole in the high part of sand hill, packing water containing soil inside film bag with cracks and setting inside the planting hole and planting grass or tree seedling in the film bag. The present invention spreads simulating grass to inhibit sand flying, plants in the high part of sand hill to absorb evaporated underground water, packs soil to avoid loss, and sucks underground water with water sucking nail, so as to utilize underground water fully in afforesting desert and reduce needed post-management.

Description

technical field [0001] The invention relates to a method for controlling deserts, especially a method for sand-fixing, water-retaining, grass-planting and tree-planting for afforesting deserts. Background technique [0002] There are large deserts all over the world, and they are still expanding rapidly. The frequency of sandstorms is also increasing, and the damage caused is also increasing. Although people from all walks of life pay more and more attention to the cause of desertification prevention and control, and spend a lot of money on desertification prevention and control, overall, the speed of governance has not kept up with the speed of desertification, and the trend of partial improvement and overall deterioration continues. The situation of people retreating has not been fundamentally contained. [0003] The existing method of desert control mainly adopts the method of building windbreaks, but this method requires a lot of investment, slow results, long cycle, di...
