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...
