Embodiment 1

[0020] Step 1: Prepare Sand Fixing Agent

[0021] Preparation of plant urease enzyme liquid: weigh dried beans, place them in a pulverizer to crush them, and pass through a 100-mesh sieve for later use (dried at low temperature and sealed for storage to prevent deterioration). Weigh soybean powder and dissolve in water to make soybean powder solution, the concentration of soybean powder is 40g / L. Centrifuge the soy flour solution. The centrifugation process uses a low-temperature high-speed centrifuge. Set the centrifugation temperature to 4°C, the rotation speed to 4000r / s, and the centrifugation time to 15 minutes. After the centrifugation process, discard the bean dregs at the bottom of the centrifuge tube and take the upper clear liquid to obtain plant urease enzyme liquid.

[0022] Preparation of inorganic treatment solution: the concentration of urea is 0.25mol / L, and the concentration of calcium chloride is 0.25mol / L.

[0023] The prepared plant urease enzyme liquid a...

[0034] Step 1: Prepare Sand Fixing Agent

[0035]Preparation of plant urease enzyme liquid: weigh dried beans, place them in a pulverizer to crush them, and pass through a 100-mesh sieve for later use (dried at low temperature and sealed for storage to prevent deterioration). Weigh soybean powder and dissolve it in water to make soybean powder solution, the concentration of soybean powder is 20g / L. Centrifuge the soy flour solution. The centrifugation process uses a low-temperature high-speed centrifuge. Set the centrifugation temperature to 2°C, the rotation speed to 3000r / s, and the centrifugation time to 10 minutes. After the centrifugation process, discard the bean dregs at the bottom of the centrifuge tube and take the upper clear liquid to obtain plant urease enzyme liquid.

[0036] Preparation of inorganic treatment solution: the concentration of urea is 0.05 mol / L, and the concentration of calcium nitrate is 0.05 mol / L.

[0049] Preparation of plant urease enzyme liquid: weigh dried beans, place them in a pulverizer to crush them, and pass through a 100-mesh sieve for later use (dried at low temperature and sealed for storage to prevent deterioration). Take soybean powder and dissolve it in water to make soybean powder solution, and the concentration of soybean powder is 160g / L. Centrifuge the soy flour solution. The centrifugation process uses a low-temperature high-speed centrifuge. Set the centrifugation temperature to 6°C, the rotation speed to 6000r / s, and the centrifugation time to 30 minutes. clear liquid to obtain plant urease enzyme liquid.

[0050] Preparation of inorganic treatment liquid: the concentration of urea is 0.5 mol / L, and the concentration of calcium chloride is 0.5 mol / L.

[0051] The prepared plant urease enzyme solution and the inorganic treatment solution are uniformly mixed at a volume ratio of 1:5 to obtain a sand-fixing a...

Abstract

The invention discloses a desert greening planting structure and a method for planting plants in a desert, wherein the planting structure is characterized in that, a planting pit is downwards arrangedon a surface of a desert sand soil layer, an anti-seepage water-retaining layer is arranged on the surface of the planting pit, sand soil is backfilled after the plants are planted in the planting pit to form a planting and sowing layer, a solidified sand soil layer and a bean dreg fertilizer layer are sequentially covered thereon; and the anti-seepage water-retaining layer and the solidified sand soil layer are obtained by treating through a sand-fixing agent containing plant urease liquid. The bean dreg fertilizer layer provides fertilizer needed by plant growth and improves a survival rateof the plants; and has certain anti-seepage and cohesive effects, so that water evaporation of surface sand soil is reduced, and wind erosion of the sand soil above the planting pit is reduced. The method for planting the plants in the desert comprises the following steps of: digging the planting pit in desert sand soil, and treating the surface of the planting pit with the sand fixing agent to form the anti-seepage water-retaining layer; planting the plants in the planting pit and backfilling the sand soil to form the planting and sowing layer; treating the surface of the planting and sowinglayer by using the sand fixing agent to form the solidified sand soil layer, and finally applying the bean dreg fertilizer to form the bean dreg fertilizer layer.

Description

technical field [0001] The invention relates to a desert greening planting structure and a method for planting plants in the desert, belonging to the technical field of desert control. Background technique [0002] The area of ​​desert and desertified land in my country is about 1.607 million square kilometers, accounting for 16.7% of the country's land area. Currently, the area of ​​desertified land in my country is expanding at a rate of 2,460 square kilometers per year, and there is a tendency to accelerate expansion. Land desertification is one of the most serious ecological environment problems in our country at present, which has brought great harm to our national economy and social development. [0003] Poor climatic conditions in desert areas, easy wind erosion of sandy soil, barren sandy land and lack of water are all problems for planting in deserts. Traditional plant planting methods are not suitable for desert areas and require a lot of manpower and material res...
