Problems solved by technology

The disadvantage of this method is that the ecological cloth cannot play the role of anti-seepage and cannot effectively store water; in addition, the ecological composite bag uses non-woven geotextiles, only herbs can germinate, and woody plants are difficult to grow.

Embodiment 1

[0011] Embodiment 1: the operation steps are as follows:

[0012] 1) Use mechanical scraping to form shallow tanks on the sandy land. The distance between the shallow tanks is 1m, the width is 1.0m, and the depth is 1.0-2.0cm.

[0013] 2) Spread the bentonite anti-seepage blanket with a thickness of 3mm on the bottom of the shallow tank in step 1), and fix it with bamboo nails.

[0014] 3) Preparing the sand control substrate, the component distribution ratio is soil activation powder: soil = 2: 45 and the mixed material is mixed evenly in parts by weight.

[0015] 4) Use a spreader to evenly spread the sand control matrix obtained in step 3) in the shallow tank of step 2), with a thickness of 12 cm, and lightly press to make it more compact.

[0016] 5) On the surface of the sand control substrate in step 4), the vegetation net is laid, so that the vegetation net and the vegetation net sand control substrate are closely attached. Use bamboo nails to fix the vegetation net o...

Embodiment 2

[0019] Embodiment 2: the operation steps are as follows:

[0020] 1) Use machinery to scrape the sand to form shallow grooves on the sandy land. The distance between the shallow grooves is 1.5m, the width is 0.5, and the depth is 1.0-2.0cm.

[0021] 2) Spread the bentonite anti-seepage blanket with a thickness of 5mm on the bottom of the shallow tank in step 1), and fix it with bamboo nails.

[0022] 3) Prepare the sand control substrate, the component distribution ratio is soil activation powder:soil=4:55 in parts by weight, and mix evenly.

[0023] 4) Use a fertilizer spreader to evenly spread the sand control matrix obtained in step 3) in the shallow tank of step 2), with a thickness of 15 cm, and lightly press to make it more compact.

[0024] 5) Lay the vegetation net on the surface of the sand control substrate in step 4), make the vegetation net and the vegetation net sand control substrate close to each other, fix the vegetation net on the sand with bamboo nails, and ...

Embodiment 3

[0027] Embodiment 3: the operation steps are as follows:

[0028] 1) Use machinery to scrape the sand on the sandy land to form shallow troughs with a distance of 1.2m, a width of 0.7m, and a depth of 1.0-2.0cm.

[0029] 2) Spread the bentonite anti-seepage blanket with a thickness of 2mm on the bottom of the shallow tank in step 1), and fix it with bamboo nails.

[0030] 3) Prepare the sand control substrate, the component distribution ratio is soil activation powder:soil=5:65 in parts by weight, and mix evenly.

[0031] 4) Use a fertilizer spreader to evenly spread the sand control matrix obtained in step 3) in the shallow tank of step 2), with a thickness of 8 cm, and lightly press it to make it more compact.

[0032] 5) Lay the vegetation net on the surface of the sand control substrate in step 4), make the vegetation net and the sand control substrate close to each other, fix the vegetation net on the sandy ground with bamboo nails, and manage the watering until the vege...

Abstract

The invention provides a plant net sand governing method, which comprises the following steps: scrapping a shallow groove body on sandy ground; paving a bentonite impervious blanket at the bottom of the shallow groove body; preparing a sand governing substrate and paving the sand governing substrate into the shallow groove body; then, paving a plant net on the surface of the sand governing substrate and fixing the plant net; and carrying out watering management until the plant cover sprouts. The method can prevent the moisture seepage, preserve the moisture, reduce the evaporation, effectively improve the moisture utilization efficiency, meet the moisture requirement of the seed sprouting, the growth and the development, and protect the surface sand and soil through the coverage of the plant net. After the plant cover develops, the soil environment of the sandy ground is fixed for a long time and is improved. The invention is mainly used for the sand prevention and sand governing engineering.

Description

technical field [0001] The invention relates to a method for preventing and controlling sand, in particular to a method for controlling sand with planting nets. Background technique [0002] The total area of ​​deserts in my country has reached 1.689 million square kilometers, accounting for about 17.6% of the total land area of ​​the country, and is expanding at an average rate of 2460 square kilometers per year. Land desertification, sandstorms and other issues have seriously affected and threatened the human living environment and sustainable social development, and have become severe problems restricting human survival and development. At present, the methods of desertification prevention and control are mainly divided into plant sand control, engineering sand control and chemical sand control methods. Chinese patent CN 1166269C discloses a greening method for sandy land and the structure used in the method, that is, in the cavity formed by excavation with the required ...
