Problems solved by technology

[0004] At present, the main problems in the process of lawn planting are: the root system activity of lawn plants is weak in the seedling stage, and the growth of aboveground parts is slow, and the characteristics of weak early growth of lawn plants often make lawn plants in the early stage of growth. Grasses are in a disadvantaged position in the competition, which can lead to the failure of turf establishment; in addition, under the environmental conditions of drought and water shortage, the phenomenon that turf plants are at a disadvantage in the competition with weeds in the early growth stage is particularly prominent; This directly affects the survival rate of lawn plants
And for these problems existing in the initial stage of lawn establishment, the measures usually taken in this field are: after clearing the ground cover plants of establishment again, the lawn bed is adjusted again, and the seedlings are replenished or the original lawn is removed to carry out the lawn establishment again. As we all know, this will greatly waste manpower, material and financial resources, and increase the cost of lawn plant establishment and management.
In order to improve the growth potential of lawn plants in the initial stage of planting, some reagents are also sprayed on the surface of lawn plants, such as surfactants, so that the stomata transpiration area on the leaf surface of lawn plants is reduced, and the evaporation of water is reduced to improve drought resistance. , and achieve the goal of enhancing the initial growth potential of lawn plants, but this method is also restricted by factors such as the cost of these reagents and the selection of appropriate dosages, and is limited in practical application

Embodiment 1

[0020] The application method of cerium nitrate in lawn planting technology is:

[0021] (1) Perennial ryegrass (Lolium perenne.L) seeds with full and uniform grains were treated with a concentration of 52.5mg L -1 Cerium nitrate aqueous solution soaked for 24 hours;

[0022] (2) Sow the soaked seeds evenly on the planting substrate with a seeding density of 35.0g / m 2 , 24°C; humidity was 55%, cultured under natural light, watered once a day in the morning and evening, cultivated under natural light, and the position of each culture dish was often changed to ensure consistent light.

[0023] Cerium nitrate adopts cerium nitrate produced by Tianjin Delan Fine Chemical Factory, and its molecular formula is: Ce(NO 3 ) 3 ·6H 2 O, the following examples all adopt this cerium nitrate.

Embodiment 2

[0025] The application method of cerium nitrate in lawn planting technology is:

[0026] (1) Treat lawn plant tall fescue (Festuca arundinacea.L) seeds with a concentration of 50 mg·L -1 cerium nitrate aqueous solution for 28 hours.

[0027] (2) Sow the soaked seeds evenly on the planting substrate with a seeding density of 35.0g / m 2 , 22.6°C; the humidity is 40%, cultivated under natural light.

Embodiment 3

[0029] The application method of cerium nitrate in lawn planting technology is:

[0030] (1) The lawn plant perennial ryegrass seeds were treated with a concentration of 300mg L -1 cerium nitrate aqueous solution for 12 hours.

[0031] (2) Sow the soaked seeds evenly on the planting substrate with a seeding density of 40.0g / m 2 , 27.5°C; humidity 70%, cultivated under natural light.

Abstract

The invention relates to a method for using cerous nitrate to plant lawn, wherein said method comprises that (1), using cerous nitrate solution to emerge the seed of lawn plant; (2), planting the emerged seed and cultivating; or planting said seed into the soil cultivate bed, while said coil contains cerous nitrate, to be cultivated. The invention can improve the activity of seed, to accelerate the growth of seedling. And it can reduce cost.

Description

technical field [0001] The invention relates to the application of cerium nitrate in the technical field of urban lawn establishment, in particular to the application in the early stage of lawn establishment. The application of this technology can improve the initial growth potential of lawns, enhance the competitiveness of lawn plants and weeds, and improve the drought resistance of lawn plants. Background technique [0002] Rare earth elements (or rare earth metals) include fifteen elements of Group IIIB in the periodic table of elements and scandium and yttrium that also belong to IIIB. Since the 1970s, the application of rare earths in crop production has been reported. In recent years, research in this field has received special attention. The research on the application of rare earths in crop production mainly involves the following content: a certain amount of rare earths can improve the quality and root activity of seedlings, and promote their growth. Rare earths c...
