Application of GLDA (tetrasodium glutamate diacetate) and IDS in enhancing ornamental quality of rye grass

Abstract

The invention discloses an application of complexing agents in enhancing ornamental quality of rye grass with an aim to enhance growth of seedlings and synthesis of chlorophyll and carotenoids. The complexing agents refer to GLDA (tetrasodium glutamate diacetate) and IDS with the concentration of 6-9mmol kg<1>; the complexing agents GLDA and IDS with respective concentration of 9mmol kg<1> are used for increasing total chlorophyll and carotenoid content; the complexing agents GLDA and IDS with respectively concentration of 6mmo kg<1> are used for increasing the total chlorophyll and carotenoid content; the complexing agents of GLDA and IDS with concentration of 3mmol kg<1> are used for increasing total chlorophyll and carotenoid content. The GLDA or IDS different in concentration are added to a turf medium, and enhanced regulation on synthesis of the GLDA or IDS on the chlorophyll and carotenoid of the rye grass is realized; technical support for green quality of the rye grass can be further improved.

Description

technical field [0001] The invention belongs to the technical field of landscaping and relates to the application of complexing agents containing GLDA and IDS in enhancing the ornamental properties of ryegrass. Background technique [0002] With the development of industrial technology, environmental problems have become increasingly prominent, and the problem of soil pollution by heavy metals is not uncommon. At present, there are different degrees of pollution in the soil of all countries in the world. The average annual emissions of Hg, Cu, Pb, Mn, and Ni in the world are about 1.5×10 4 , 3.4×10 6 , 5×10 6 , 1.5×10 7 、10 6 t. The area of ​​cultivated land polluted by Cd, Hg, As, Cr, and Pb in my country is about 2×10 7 hm 2 , About 1 million tons of grain are lost every year due to heavy metal pollution. Therefore, people pay more and more attention to the remediation of heavy metal-contaminated soil. Phytoremediation technology belongs to in-situ restoration tec...
