The invention relates to a method for improving the salt tolerence of lawn grass by filling waste crumb rubber as a slat press layer into soil and application of the waste crumb rubber to improving the salt tolerence of a lawn plant such as festuca arundinacea. A result shows that the waste crumb rubber can improve the underground biomass and the chlorophyll content of plants to a certain degree; and with the addition of the waste crumb rubber, the activity of superoxide dismutase (SOD) can be remarkably increased within the preset concentration of NaCl. By selecting the waste crumb rubber as a soil medium and constructing the slat press layer, the invention not only can improve the ventilation, the water potential and other physical properties of soil, but also can improve the elasticity of a lawn matrix; and the waste crumb rubber is superior to other soil additions and improves the salt tolerance of the festuca arundinacea.
Description
Method for improving the salt-resistant performance of turfgrass by filling the soil with waste rubber particles into the salt layer technical field 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-pressed layer to improve the salt-resistant ability of lawn plants. Background technique 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 Ling...
