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) On the sandy ground, mechanical scraping of sand and soil is used to form shallow troughs. The spacing between shallow troughs is 1m, the width is 1.0m, and the depth is 1.0-2.0cm.

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

[0014] 3) Preparation of sand control matrix, the component proportion of which is mixed material of soil activation powder:soil=2:45 in parts by weight and mixes evenly.

[0015] 4) The sand control matrix obtained in step 3) is evenly spread in the shallow groove body of step 2) by using a spreader, and the spreading thickness is 12 cm, and lightly pressed to make it more compact.

[0016] 5) In step 4), a plant net is laid on the surface of the sand control matrix, so that the plant net and the plant net sand control matrix are in close contact. The planting net was fixed on...

Embodiment 2

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

[0020] 1) On the sandy ground, mechanical scraping of sand and soil is used to form shallow troughs with a spacing of 1.5m, a width of 0.5, and a depth of 1.0-2.0cm.

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

[0022] 3) Preparation of sand control matrix, the component proportion of which is soil activation powder:soil=4:55 in parts by weight, and the mixture is evenly mixed.

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

[0024] 5) Lay a plant net on the surface of the sand control substrate in step 4), so that the plant net and the plant net sand control matrix are in close contact, and the plant net is fixed on the sandy ground with bamboo nails, ...

Embodiment 3

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

[0028] 1) Shallow troughs are formed by mechanical scraping of sand on the sandy ground. The spacing between the shallow troughs is 1.2m, the width is 0.7m, and the depth is 1.0-2.0cm.

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

[0030] 3) Prepare a sand control matrix, the component proportion of which is soil activation powder:soil=5:65 in parts by weight, and the mixture is evenly mixed.

[0031] 4) The sand control matrix obtained in step 3) is evenly spread in the shallow groove body of step 2) by using a fertilizer spreader, and the spreading thickness is 8cm, and lightly pressed to make it more compact.

[0032] 5) A planting net is laid on the surface of the sand control matrix in step 4), so that the planting net and the sand control matrix are in close contact, and the planting net is fixed on the sa...

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 by 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 country's total land area, and is expanding at an average rate of 2,460 square kilometers per year. Problems such as land desertification and sandstorm have seriously affected and threatened human living environment and sustainable social development, and have become serious problems restricting human survival and development. At present, the methods of sand 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 ground and the like and a structure used in the method, that is, a cavity with a desired cross-sectional area and depth formed by excavation...
