Problems solved by technology

Lawn plants have weak root activity in the seedling stage, and the growth of the aboveground parts is slow, and the characteristics of weak early growth of lawn plants often make lawn plants in a disadvantaged position in the competition with weeds in the early stage of growth. Such results can lead to Lawn planting failure; in addition, under the environmental conditions of drought and water shortage, the phenomenon that lawn plants are at a disadvantage in the early stage of growth is particularly prominent in the competition with weeds; this directly affects the survival rate of lawn plants; The biggest difficulty in the application of planting in practice, that is, the problem of lawn planting experiencing technical "bottleneck" constraints

Embodiment 1

[0071] (1) Sow ryegrass on the mixed culture substrate for lawn establishment. 2kg of mixed culture substrate soil contains 300 mg / Kg of rare earth cerium, and the sowing density is 35.0g / m 2 At the initial stage of sowing, water each pot fully to ensure the smooth germination of the seeds and the initial growth of the seedlings;

[0072] (2) After three weeks, water should be given quantitatively according to the degree of stress, and then weighed and watered every two days to maintain within the range of stress. 70% (weight) field maximum water holding capacity, medium is 65% (weight), heavy is 35% (weight);

[0073] (3) The culture conditions are as follows: at a humidity of 68%, light during the day, a temperature of 22°C, and a temperature of 18°C ​​at night, culture for 40 days, and a light intensity of 800 μmol m -2 the s -1 ;

[0074] (4) The lawn plant ryegrass is established according to the management requirements of ordinary lawn plants; after the ryegrass grows...

Embodiment 2

[0076] (1) Sow the lawn plant tall fescue seeds on the mixed culture medium for lawn establishment, 1.5-2kg mixed culture medium soil contains rare earth cerium 500 mg / Kg, 45.0g / m 2 ;In the initial stage of sowing, water each pot fully to ensure the smooth germination of seeds and the initial growth of seedlings;

[0077] (2) After three weeks, water should be given quantitatively according to the degree of stress, and then weighed and watered every two days to maintain within the range of stress. 80% (weight) field maximum water holding capacity, medium is 55% (weight), heavy is 40% (weight);

[0078] (3) The culture conditions are as follows: the humidity is 68%, the daylight is illuminated, the temperature is 26°C, and the nighttime temperature is 22°C, cultured for 60 days, and the light intensity is 900 μmol m -2 the s -1 ;

[0079] (4) During the establishment of the lawn plant tall fescue, it is carried out according to the management requirements of ordinary lawn pl...

Abstract

The invention relates to a method for planting lawn plants by combining rare earth cerium with mixed culture matrices. The method comprises the step of sowing seeds of lawn plants on mixed culture matrices for lawn planting, wherein 1.5-2kg of mixed culture matrix soil contains 200-800mg/Kg of rare earth cerium, and the mixed culture matrices refer to soil and municipal solid waste compost in a ratio of parts by weight of 4: (1-2). By applying a certain amount of rare earth cerium, the activities of protective enzymes of the lawn plants can be obviously improved, and the defence capability of the protective enzyme system can be enhanced, thus improving the drought resistance of the lawn plants. Efficient and low-cost operation modes in large-area municipal lawn planting are expected to be achieved through the application of the technology.

Description

technical field [0001] The invention relates to the application of rare earth cerium in the technical field of urban lawn construction, in particular to a method for planting lawn plants in combination with rare earth cerium and mixed culture substrate. 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] As an ecosystem, lawn is a huge carbon source storehouse, and grassland soil in the world can absorb and deposit 0.01-0.3Gt of carbon every year. thus reducing CO in the air 2 to reduce the greenhouse effect to a certain extent. Secondly, the dense surface covering layer and grass root layer formed by the turf have a good effect on preventing soil erosion; the turf can also reduce the daily temperature difference on the surface, so it can effectively reduce the soil collapse caused by "frost heave". The la...
