Problems solved by technology

The winter in northern my country is cold, and it is difficult for turfgrass to survive the winter. In spring and autumn, it is often attacked by cold currents, causing spots, late germination in spring, early aging in autumn, and poor growth, which affects the appearance of the lawn and reduces the use value of the lawn.
Low temperature stress has become the limiting factor for improving the use value of turf in northern my country

Embodiment 1

[0058] (1) The compost is selected from the waste compost after fermentation in the waste composting plant;

[0059] (2) Add 70 g of the above-mentioned compost in a petri dish, weigh 1.5 g of tall fescue seeds and sow them in each petri dish, germinate and grow initially at room temperature;

[0060] (3) During the period of germination and initial growth, the indoor temperature is 18°C ​​and the relative humidity is 40%. Add 0.2g·kg to the compost culture medium 16 days after sowing -1 concentration of lanthanum nitrate;

[0061] (4) Continue culturing for 6 days after adding lanthanum nitrate, and then move the petri dish into a light incubator for cold stress treatment. The temperature is set at 15-10°C day and night, the light time is 9 hours, the light intensity is 100, and the experiment period is 34 hours. Days, in the 9 days of cold stress to carry out the determination of the resistance index.

Embodiment 2

[0063] (1) The compost is selected from the waste compost after fermentation in the waste composting plant;

[0064] (2) Add 70 g of the above-mentioned compost in a petri dish, weigh 1.5 g of tall fescue seeds, sow in each petri dish, germinate and grow initially at room temperature;

[0065] (3) During the germination and initial growth period, the indoor temperature is 28°C and the relative humidity is 60%. Add 0.4 g·kg to the compost culture medium 16 days after sowing -1 concentration of lanthanum nitrate;

[0066] (4) Continue culturing for 6 days after adding lanthanum nitrate, and then move the petri dish into a light incubator for cold stress treatment. The temperature is set at 15-10°C day and night, the light time is 9 hours, the light intensity is 100, and the experiment period is 34 hours. Days, in the 9 days of cold stress to carry out the determination of the resistance index.

Abstract

The invention relates to a method for using lanthanum to improve cold resistance of tall fescue turf based on garbage compost medium, which includes: adding 70g of compost into each petri dish, sowing 1.5g of weighed seeds of tall fescue into each petri dish, and allowing the seeds to germinate and grow preliminarily at the room temperature; controlling the indoor temperature to be 18-28 DEG C and the relative humidity to be 40%-60% during the period of germination and preliminary growth, adding 0.2-0.4g, kg-1 lanthanum nitrate into the compost medium 16 days after sowing; continuing cultivation for 6 days after the lanthanum nitrate is added, moving the petri dishes into a lighting culture box, subjecting the petri dishes to cold stress treatment, and testing adversity resistance indexes when cold stress treatment is performed for 3-9 days, wherein cold stress temperature is set as 15/10 DEG C at night, lighting time is set as 9h, light intensity is set as 100 and the testing cycle is set as 34 days. Test results show that tall fescue can be induced to resist cold stress by lanthanum treatment and damage of the tall fescue by cold can be alleviated.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a method for cultivating tall fescue with compost of municipal domestic garbage as a substrate. More specifically, it is a method for lanthanum to improve the low temperature resistance of tall fescue turf as a waste composting matrix. Background technique [0002] At present, there are many problems in the production of turf in our country, which cannot meet the needs of urban turf establishment, and the lack of development and supply of turf substrate is an important limiting factor. In turf production, every time the turf production process is completed, at least 2 cm of mellow soil must be shoveled away. After 3 to 4 consecutive operations, the fertile farmland will be destroyed. To restore the fertility of the topsoil, it will take a few years at the shortest, and decades or hundreds of years at the most. For this reason, it is of great practical significanc...
