Embodiment 1

[0049] (1) Adopting the method of tall fescue potted planting, put the waste rubber particles with a diameter of 0.5mm as the salt storage layer on the bottom of the container at 20 cm, and place the soil on it to form a matrix salt storage layer, wherein the ratio of soil to rubber particles is 10 : 1, the seeding rate of every pot of tall fescue is 0.5g;

[0050] (2) Salt stress is carried out after sowing 15 days after the seedlings have fully emerged, and the stress mode is progressive stress, that is, once every 5 days, adding an aqueous solution containing 0.2% NaCl to the salt storage layer matrix each time, and the stress is completed after 20 days;

[0051] (3) After the stress was finished, tall fescue continued to be cultivated for 15 days, and the above-ground parts of the plants were taken to measure various physiological indicators; wherein the average temperature during the test was 18°C, and the average relative humidity was 37.1%; the light was natural incident...

Embodiment 2

[0054] (1) Adopting the method of tall fescue potted planting, put the waste rubber particles with a diameter of 1mm as the salt storage layer at the bottom of the container 30cm, and place the soil on it to form a matrix, wherein the ratio of soil to rubber particles is 10:1, and each The sowing amount of potted tall fescue is 0.5g;

[0055] (2) Salt stress is carried out after sowing 15 days after the seedlings have fully emerged, and the stress mode is progressive stress, that is, once every 5 days, adding an aqueous solution containing 0.4% NaCl to the salt storage layer matrix each time, and the stress is completed after 20 days;

[0056] (3) After the stress was finished, tall fescue continued to be cultivated for 15 days, and the above-ground parts of the plants were taken to measure various physiological indicators; wherein the average temperature during the test was 18°C, and the average relative humidity was 37.1%; the light was natural incident light; During the cul...

Embodiment 3

[0058] (1) Adopting the method of tall fescue potted planting, put the waste rubber particles with a diameter of 0.8mm as the salt storage layer at the bottom of the container at 30 cm, and place the soil on it to form a matrix, wherein the ratio of soil to rubber particles is 10:1, The sowing amount of each pot of tall fescue is 0.5g;

[0059] (2) Salt stress is carried out after sowing 15 days after the seedlings have fully emerged, and the stress mode is progressive stress, that is, once every 5 days, adding an aqueous solution containing 0.8% NaCl to the salt storage layer matrix each time, and the stress is completed after 20 days;

[0060] (3) After the stress was finished, tall fescue continued to be cultivated for 15 days, and the above-ground parts of the plants were taken to measure various physiological indicators; wherein the average temperature during the test was 18°C, and the average relative humidity was 37.1%; the light was natural incident light; During the c...

Abstract

The invention relates to a method for improving the salt resistance of a lawn plant by filling soil through adopting a waste colloidal particle as a salt storing layer and application of the waste colloidal particle in improving the salt resistance aspect of the lawn plant Festuca arundinacea. Results indicate that the waste colloidal particle can improve the underground biomass and chlorophyll content of the plant to a certain extent; and the addition of the waste colloidal particle obviously improves the activity of superoxide dismutase (SOD) in the set NaCl concentration range. The invention not only can improve the physical characteristics of soil air permeability, soil water potential, and the like but also can improve the elasticity of a lawn substance by adopting the waste colloidal particle as a soil medium and constructing the salt storing layer, and is unmatched with other soil additives; and the waste colloidal particle improves the salt resistance of the Festuca arundinacea.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a rational and safe use method of waste rubber particles. More specifically, it is a method and application of using waste rubber particles to fill soil in a salt storage layer to improve the salt resistance ability of lawn plants. Background technique [0002] Soil salinization has become one of the global hot ecological issues and has received extensive attention. In soil salinization control measures, the use of exogenous filling materials such as gypsum, organic polymers, waste fly ash, sand, and various fertilizers can improve the structure of saline soil, accelerate salt discharge, and promote the growth of plants in salinized soil. The purpose of absorbing and utilizing water and nutrients under certain conditions. The research of Zhang Lingyun and Zhao Gengxing showed that the application of saline soil remediation materials can reduce soil salinity, bulk ...
