B, water retention: chinampa has heat-proof quality, can reduce underground water evaporates speed; The impermeable material substrate layer of chinampa can stop the steam that contains in the following sand bed to volatilize, be lost in the air;

C, water guide effect: cover the steam that contains in the sand bed below the chinampa and can only concentrate by upwards volatilization of implantation hole, part rainwater or snow-broth also can focus on the implantation hole position and permeate downwards owing to the existence of chinampa impermeable material substrate, thereby make the implantation hole position keep moistening for a long time, possesses good moisture condition, adding that implantation hole is filled out is placed with soil, is very beneficial for growth and development of plants.

2, method of the present invention can make full use of the groundwater resources of desert preciousness to greatest extent.

3, the rough sand layer that is sprinkling upon above the chinampa can play a protective role to chinampa; alleviate the degree that it is subjected to Exposure to Sunlight; reduce its aging speed, it can be played a role for a long time, overcome and used methods such as liquid mulch film, nutrients immobilized water can only produce the shortcoming of short run effect in the past.

4, can be directly from fix the sand, water conservation and greening is tripartite carries out comprehensive improvement in the face of the desert, have instant effect, short advantage of cycle.

5, can plant economic crops in the implantation hole position, overcome the shortcoming that traditional improvement desert " has only input, is difficult to output ".

6, method of the present invention both had been suitable for the regulation of desertification land is suitable for preventing desertification again.
