Embodiment 1

[0017] (1) Soak 50 grains of ryegrass and tall fescue seeds in the mixed solution for 12 hours; wherein the mixed solution is made of 1.0g / L ammonium nitrate and 5mmol / L malic acid or 15mmol / L citric acid in a volume of 1:0.01 Than composition.

[0018] (2) on the saline soil containing 0.2% salt, sow soaked ryegrass and tall fescue seeds with 20g / square meter;

[0019] (3) Seed soaking in distilled water and 1.0 g / L ammonium nitrate solution alone were used as controls. Using natural light conditions, during the germination and cultivation of lawn plants, the average temperature in the laboratory is 17.5°C, and the average humidity is 42.9%. Test result sees embodiment 2.

Embodiment 2

[0020] Example 2

[0021] 1 Development method

[0022] 1.1 Test material

[0023] Perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea L.) were used in this experiment. The organic acids are citric acid and malic acid. The mixed solution is composed of 1.0g / L ammonium nitrate and 5-20mmol / L malic acid or citric acid in a volume ratio of 1:0.01-0.03. Preferably, the concentration of malic acid is 5mmol / L, the concentration of 10mmol / L citric acid is 15mmol / L, and the soaking time of 20mmol / L is 12h. Two layers of filter paper were placed in the petri dish to soak the seeds. There were 50 lawn plant seeds, and they were subjected to stress research at a strength of 0.2% salt. The experiment was set up with 4 repetitions. Among them, soaking seeds in distilled water and 1.0 g / L ammonium nitrate solution alone were used as controls. The seed soaking test was carried out on the experimental bench in the laboratory under natural light conditions. During...

Abstract

The invention discloses application of soaking seeds in mixed liquor in improving salt resistance of lawn plants; wherein, the mixed liquor is formed by 1.0g / L ammonium nitrate and 5-20mmol / L malic acid or citric acid based on the volume ratio of 1:0.01-0.03; salt resistance is saline soil containing 0.1-0.4% of salt. In the invention, after being applied to the mixed liquor, the soaking seeds have good promoting actions on salt resistance in height, chlorophyll, aboveground biomass, root growth and the like of two lawn plants and can provide a theoretical basis for pre-sowing treatment of the lawn plants and wider application of the mixed liquor in the lawn plant field.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to the application of soaking seeds in a mixed solution in improving the salt resistance of lawn plants. More specifically, it is the application of soaking seeds in a mixture of organic acid and ammonium nitrate in improving the salt resistance of lawn plant species. Background technique [0002] Lawn is an indispensable element in modern landscaping and green spaces. In addition to its functions of improving the environment, it also has unique artistic functions in gardens and green spaces. However, there are still many problems in the construction and development of turfgrass in my country, such as the vigor of turfgrass seeds, the control of diseases and insect pests, and the disconnection between the construction and development of turfgrass and the ecological environment. In the process of lawn planting, the quality and vigor of lawn plant seeds are an importan...
