Embodiment 1

[0041] Embodiment 1. Preparation of inorganic clay-flax gum (flax gum) water-retaining material

[0042] 1) After removing impurities, loess and laterite are mixed at a mass ratio of 1:0.2, dried, and crushed to 100-200 mesh;

[0043] 2) Add flax gum into deionized water at a mass ratio of 1:300, heat (45~65°C) and stir (300~500r / min, 60~120min.) to form a gel, and then add inorganic Clay (the mass of flax gum is 4.0~6.0%) is fully stirred (the speed is 300~600r / min, and the time is 30~60min.), mixed, granulated, and dried to obtain the inorganic clay-flax gum composite water-retaining material;

[0044] 3) Prepare the inorganic clay-flax glue water-retaining material into a viscous turbid liquid with a concentration of 0.75g / ml, and then spread it evenly on the upper layer of the soil and press it to form a soil-based water-retaining layer. At 70.5 hours, the water retention rate of the inorganic clay-flax glue water-retaining material is more than 31.08% higher than that of...

Embodiment 2

[0045] Example 2. Preparation of Inorganic Clay-Artemisia Gum Water-Retaining Material

[0046] 1) After removing impurities, loess and red clay are mixed at a mass ratio of 1:1, dried, and crushed to 100-200 mesh;

[0047] 2) Add Artemisia gum to deionized water at a mass ratio of 1:400, heat (45~65°C) and stir (300~500r / min, 60~120min.) to form a gel, and then add Inorganic clay (the mass of Artemisia gum is 4.0~6.0%) is fully stirred (the speed is 300~600r / min, and the time is 30~60min.), mixed, granulated, and dried to obtain the inorganic clay-Artemisia glue water-retaining material ;

[0048] 3) Prepare the inorganic clay-artemisia glue water-retaining material into a viscous turbid liquid with a concentration of 0.75g / ml, and then spread it evenly on the upper layer of the soil, and press it to form a soil-based water-retaining layer. At 72 hours, the water retention rate of the inorganic clay-artemisia gum water-retaining material was more than 28.81% higher than tha...

Embodiment 3

[0049] Embodiment 3, the preparation of inorganic clay-squat gum water-retaining material

[0050] 1) After removing impurities, loess and red clay are mixed at a mass ratio of 1:2, dried, and crushed to 100-200 mesh;

[0051] 2) Add inorganic clay-squat gum into deionized water at a mass ratio of 1:500, heat (45~65°C) and stir (300~500r / min, 60~120min stirring time) to form a gel , then add inorganic clay (mass of Tianjing gum is 4.0~6.0%) and stir well (rotating speed is 300~600r / min, time is 30~60min.) Mix evenly, granulate and dry to get inorganic clay-Azuna Glue composite water-retaining material.

[0052] 3) Make the inorganic clay-squat gum water-retaining material into a viscous turbid solution with a concentration of 0.75g / ml, and then spread it evenly on the upper layer of the soil, and press it to form a soil-based water-retaining layer. At 91.5 hours, the water retention rate of the inorganic clay-squat gum water-retaining material was more than 26.40% higher tha...

Abstract

The invention discloses a preparation method of an inorganic clay-biological glue compound water-retention material. Biological glue is added into deionized water, a mixture is heated and stirred intogel, then inorganic clay is added for full stirring and even mixing, and granulation and drying are conducted to obtain the inorganic clay-biological glue compound water-retention material, wherein the inorganic clay is a mixture of red clay and loess, and a mass ratio of the red clay to the loess is 1 to (0.2 to 5). The red clay and the loess not only can reduce the production cost of the soil water-retention material, but also can provide necessary nutrient substances for plant growth; the biological glue has high cohesion action, can prevent water and soil loss and has the performance of inhibiting soil moisture evaporation well and the effects of water retention, soil conservation, fertilizer conservation, yield improvement and the like; the water-retention material prepared through the method has excellent water retention performance, can effectively reduce water loss, improves the soil ecology function, provides good water and soil conditions for plant growth and promotes growthof vegetation or crops.

Description

technical field [0001] The invention relates to a water-retaining material used for soil moisture conservation, in particular to a preparation method of an inorganic clay-biological glue composite water-retaining material, which belongs to the technical field of water and soil conservation. Background technique [0002] The lack of fresh water resources is one of the most serious problems in the world today. It will threaten the basic living conditions of human beings, restrict the quality of human life, and cause great harm to human survival and development. The status quo of China's water resources is particularly not optimistic. China is a country with severe drought and water shortage. The total amount of fresh water resources is 2.8 trillion cubic meters, accounting for 6% of global water resources, ranking fourth in the world after Brazil, Russia and Canada, but the per capita is only 2,200 cubic meters. It is only 1 / 4 of the world's average level and 1 / 5 of that of ...
