Abstract

The invention relates to a method for improving the photosynthetic capacity of tall fescue by adopting saline soil filled with waste crumb rubber, which is characterized by comprising the following steps of: (1) substrate compound and preparation: placing 1000g of sand at a bottom layer, placing 20g of waste crumb rubber with the diameter of 0.5-1 mm on the bottom layer, placing 1500g of saline soil on the third layer and coating a layer of 100g loam soil on the topside, wherein the saline soil contains 0.2-0.8 percent of NaCl; after tall fescue on a lawn sprout fully and stably, transplanting the tall fescue to an experimental geobotany and deeply burying in soil by adopting a potting method; and (2) after grass on the lawn grows stably, selecting 10 grasses after 60d, measuring the photosynthetic capacity and the biomass liveweight on the ground and underground.

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 saline soil to fill waste rubber particles to improve the photosynthetic capacity of tall fescue. 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 density and pH va...
