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

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...

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
