Problems solved by technology

Although it can achieve a relatively ideal water absorption effect to a certain extent, its price is high due to the high price of raw materials or complicated manufacturing process, and some polymer materials may produce toxic substances during the degradation process, thereby polluting the soil. Application of such potentially polluting water retaining agents may lead to accumulation of toxic substances in plants

Embodiment 1

[0050] A natural sodium-based bentonite composite water-retaining material used for desertification control and quality and efficiency improvement of forestry and fruit industry. Its components are proportioned according to weight percentage. The raw material formula is as follows: 30% of natural sodium-based bentonite, 25% of licorice residue, and 10% of weathered coal %, peat soil 15%, straw 10%, vermiculite 5%, perlite 4.5%, EM bacterial agent 0.5%, its preparation method comprises the following steps:

[0051] Step 1: Pulverization and purification of bentonite

[0052]The bentonite is selected from natural sodium-based bentonite, and its dosage is 30wt% of the total amount of water-retaining materials. The natural sodium-based bentonite tailings are dry crushed and purified to separate impurities from the bentonite to obtain natural sodium-based bentonite fine powder with a fineness of 80-200 mesh.

[0053] Step 2: Refining treatment of licorice residue

[0054] The lic...

Abstract

The invention discloses a natural sodium bentonite composite water-retaining material and a preparation method thereof, and belongs to the technical field of agricultural production supplies. The natural sodium bentonite composite water-retaining material comprises, by mass, 20-30% of natural sodium bentonite, 25-35% of liquorice residues, 10-15% of weathered coal, 10-15% of turfy soil, 5-10% of straw, 5-10% of vermiculite, 4.5-9% of perlite and 0.5-1% of an EM microbial agent. The invention also provides a preparation method of the natural sodium bentonite composite water-retaining material.The natural sodium bentonite composite water-retaining material which is natural and safe is prepared by combining the properties of strong cohesiveness and water absorbability of bentonite, small volume weight and high porosity of liquorice residues, turfy soil, straws, vermiculite and perlite, and high humic acid content of weathered coal and the like, and the natural sodium bentonite compositewater-retaining material is wide in raw material source, simple in production process and suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of agricultural production supplies, and relates to a natural sodium-based bentonite composite water-retaining material and a preparation method thereof, in particular to a natural sodium-based bentonite composite water-retaining material used for desertification control and quality and efficiency improvement of forest and fruit industry and its preparation method. Background technique [0002] Water is the most basic environmental factor in the process of plant growth and development, and occupies an irreplaceable position in agriculture and forestry and fruit production. [0003] For the arid and semi-arid areas in Northwest China, there is less precipitation, strong evaporation, and deep soil layers. As a result, the buried groundwater is deep and the surface soil moisture is relatively scarce. Among them, due to the poor water retention of sandy soil, the degree of water deficit is more obvious, so that...
