Problems solved by technology

However, the ceramsite insulation and water-retaining layer has extremely high strength, so it can only be used for tall woody plants with strong and dense root systems, not for short herbaceous plants
At the same time, the raw material price of ceramsite is relatively high, which leads to the high cost of the water-retaining layer and the high cost.

Embodiment 1

[0022] (1) Preparation of lightweight porous water-retaining material: Weigh high-strength gypsum powder and soil at a mass ratio of 1:4, mix soil and water at a mass ratio of 25:9, stir to form a light material, and then Pile it into a hollow circular platform, mix high-strength gypsum powder and water according to the mass ratio of 5:3, and stir to form a slurry; finally, pour the slurry of high-strength gypsum powder and water into the hollow circular platform, and fully stir until it becomes yellowish brown Fluid, after the mixture is dried until the water content is less than or equal to 80%, an irregular lightweight porous water-retaining material is obtained; through actual tall fescue planting monitoring, the water retention rate of the lightweight porous water-retaining material prepared in this embodiment is increased by 60%.

Embodiment 2

[0024] (1) Preparation of lightweight porous water-retaining material: Weigh high-strength gypsum powder and soil at a mass ratio of 3:7, mix the soil with water at a mass ratio of 25:10, stir to form a lightweight material, and then Pile it into a hollow circular platform, mix high-strength gypsum powder and water according to the mass ratio of 5:4, and stir to form a slurry; finally, pour the slurry of high-strength gypsum powder and water into the hollow circular platform, and fully stir until it becomes yellowish-brown Fluid, after the mixture is dried until the water content is less than or equal to 80%, an irregular lightweight porous water-retaining material is obtained; through actual tall fescue planting monitoring, the water retention rate of the lightweight porous water-retaining material prepared in this embodiment is increased by 100%.

Embodiment 3

[0026] (1) Preparation of lightweight porous water-retaining material: Weigh high-strength gypsum powder and soil at a mass ratio of 2:3, mix soil with water at a mass ratio of 25:9, stir to form a lightweight material, and then Pile it into a hollow circular platform, mix the high-strength gypsum powder and water according to the mass ratio of 5:3, and stir it into a slurry; finally, pour the slurry of high-strength gypsum powder and water into the hollow circular platform, and fully stir it into yellowish brown Fluid, after the mixture is dried until the water content is less than or equal to 80%, an irregular lightweight porous water-retaining material is obtained; through actual tall fescue planting monitoring, the water retention rate of the lightweight porous water-retaining material prepared in this embodiment is increased by 100%.

[0027] The use process of the irregular lightweight porous water-retaining material prepared in Examples 1 ~ 3 is (such as figure 1Shown):...

Abstract

The invention discloses a preparation method and application method of a light water retention material. The light porous water retention material which is prepared by using phosphogypsum solid wasteas a raw material has an extremely excellent water absorption rate and water retention rate and heat preservation, and when compared with the water absorption rate of soil free of the light water retention material, the water absorption rate is improved by more than one time, and the water retention rate is increased by 70-111%. In addition, overground biomass and underground biomass are also promoted, improvement of the physiological characteristics, such as promotion of synthesis of intracellular chlorophyll, of living matter can also be improved, activity of antioxidant enzymes is improved, and nutrient metabolism in plants and the like are regulated, so that a good regulation effect on physical, chemical and biochemical properties of the soil is achieved. Therefore, the water retention material is a water retention material which has good performance and low price and is capable of achieving repeated recycling of the solid waste.

Description

technical field [0001] The invention relates to a preparation method and a use method of a lightweight water-retaining material, belonging to the fields of solid waste utilization and crop production. Background technique [0002] The issue of water resources is one of the most focused issues in the world today. Although my country has a vast territory and abundant water resources, it is a country with a small per capita share and many floods. At present, the common water-saving irrigation technologies in my country are: sprinkler irrigation technology, micro-irrigation (drip irrigation and micro-spray irrigation) technology, infiltration irrigation technology , Canal anti-seepage and low-pressure pipeline water delivery irrigation technology. Although these water-saving irrigation technologies have saved water resources to a certain extent. However, in all respects, there are still some disadvantages. Sprinkler irrigation technology: It is greatly affected by the wind, ge...
