Embodiment 1

[0035] (1) Pass the collected soil samples through a 2 mm sieve and mix them for later use; tall fescue is used for lawn plants, and diethyltriaminetetraacetic acid is used as a complexing agent for later use;

[0036] (2) The test uses a PVC pipe with a height of 25 cm and a diameter of 3 cm. After washing and drying the gauze, cut it into a round shape of appropriate size and fix it at the bottom of the PVC pipe. Put 160g of soil into the PVC pipe, and sow high sheep in each container. Mao seeds 0.2 g;

[0037] (3) Quantitative water supply every day during the experiment to meet the needs of plant growth. When tall fescue grows to the 25th day, add a concentration of 5 mmol·kg -1 DTPA;

[0038] (4) During the cultivation period, the temperature was 16°C, the relative humidity was 36%, and the light conditions were natural incident light. The whole experiment lasted 60 days, and then the tall fescue leaves were cut to measure the soil enzyme activity indicators of tall fes...

Embodiment 2

[0040] (1) Pass the collected soil samples through a 2 mm sieve and mix them for use; use tall fescue for lawn plants, and use aminotriacetic acid as a complexing agent for use;

[0041] (2) The test uses a PVC pipe with a height of 25 cm and a diameter of 3 cm. After washing and drying the gauze, cut it into a round shape of appropriate size and fix it at the bottom of the PVC pipe. Put 160g of soil into the PVC pipe, and sow high sheep in each container. Mao seeds 0.2 g;

[0042] (3) Quantitative water supply every day during the experiment to meet the needs of plant growth. When tall fescue grows to the 30th day, add a concentration of 3 mmol·kg -1 NTA;

[0043] (4) During the cultivation period, the temperature was 25°C, the relative humidity was 50%, and the light conditions were natural incident light. The whole experiment lasted 60 days, and then the tall fescue leaves were cut to measure the soil enzyme activity indicators of tall fescue lawn.

Embodiment 3

[0045] A method for regulating tall fescue proline, malondialdehyde content and electrical conductivity using a complexing agent, characterized in that it proceeds in the following steps:

[0046] (1) Pass the collected soil samples through a 2 mm sieve and mix them for use; use tall fescue for lawn plants, and use disodium edetate as a complexing agent for use;

[0047] (2) The test uses a PVC pipe with a height of 25 cm and a diameter of 3 cm. After washing and drying the gauze, cut it into a round shape of appropriate size and fix it at the bottom of the PVC pipe. Put 160g of soil into the PVC pipe, and sow high sheep in each container. Mao seeds 0.2 g;

[0048] (3) Quantitative water supply every day during the experiment to meet the needs of plant growth. When the tall fescue grows to the 28th day, add the concentration of 5mmol·kg -1 EDTA;

[0049] (4) During the cultivation period, the temperature was 25°C, the relative humidity was 40%, and the light conditions were...

Abstract

The invention discloses an application of a complexing agent in improvement of soil enzymatic activity of festuca arudinaces. The complexing agent is ethylene diamine tetraacetic acid, nitrilotriacetic acid or diethyl triamine tetraacetic acid; and the concentration of the complexing agent is 3-5mmol.kg<-1>. The experiment result shows that ethylene diamine tetraacetic acid (EDTA), nitrilotriacetic acid (NTA) and diethyl triamine tetraacetic acid (DTPA) are applied to the repair of heavy metal in soil to affect the biological environment of the soil, so as to affect the conversion of soil nutrients to affect the growth of a plant. Therefore, the health condition of the soil is evaluated when the heavy metal content in the soil is reduced; as the analysis, the method can be used as a proper reference concentration interval for the application of the EDTA when the concentration of the EDTA is smaller than 10mmol.kg<-1>; and a reference interval of the NTA is the same as that of the EDTA. As to the DTPA, the dosage can be considered to be 5mmok.kg<-1> when the economic cost and the remediation effect are synthesized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to urban greening, in particular to a method for improving soil enzyme activity of tall fescue turf by using a complexing agent. Background technique [0002] Lawn plants not only play an important role in the improvement of environmental ecology, but also all kinds of public activity places and sports venues are inseparable from lawn construction. Golf course construction is a higher level of development in the lawn industry. As a public green space with multiple functions such as beautifying the environment, purifying the air, adjusting the temperature, reducing noise, increasing prices for leisure and sports, and maintaining water and soil, lawns are important in maintaining ecological balance, beautifying the living environment, developing sports, and transportation. play an irreplaceable role. In the urban greening in recent years, the greening concept of "peopl...
