Embodiment 1

[0051] (1) Manually pick up the debris in the garbage compost, then dry it at 105°C for 8 hours to constant weight, and sieve out the compost with a particle size of 1700nm; crush the compost with a particle size of 1700nm at 24000 rpm, Prepare 1200nm, 600nm and 300nm garbage micro-fertilizers;

[0052] (2) On 180g of soil, evenly spread 3g of waste micro-fertilizers with particle sizes of 1200nm, 600nm and 300nm on the soil surface, and finally cover 20g of soil evenly on it;

[0053] (3) sow tall fescue 0.5g then, control temperature is 20 ℃, and relative humidity is 40%, and illumination is the natural light that penetrates into the room;

[0054] (4) At the initial stage of sowing, water fully to ensure that the seeds can germinate smoothly and the growth of the seedlings at the initial stage. After two weeks, water according to 55% of the field water capacity every two days to maintain the stress range, the 44th day Start to measure various indicators: biomass, root syst...

[0057] (1) Manually pick up the debris in the garbage compost, then dry it at 105°C for 8 hours to constant weight, and sieve out the compost with a particle size of 1700nm; crush the compost with a particle size of 1700nm at 24000 rpm, Prepare 1200nm, 600nm and 300nm garbage micro-fertilizers;

[0058] (2) On 180g of soil, evenly spread 3g of waste micro-fertilizers with particle sizes of 1200nm, 600nm and 300nm on the soil surface, and finally cover 20g of soil evenly on it;

[0059] (3) sow tall fescue 0.5g then, control temperature is 26 ℃, and relative humidity is 60%, and illumination is the natural light that penetrates into the room;

[0060] (4) At the initial stage of sowing, water fully to ensure that the seeds can germinate smoothly and the growth of the seedlings at the initial stage. After two weeks, water according to 50% of the field water capacity every two days to maintain the stress range, the 44th day Start measurement.

Embodiment 3

[0062] (1) Manually pick up the debris in the garbage compost, then dry it at 105°C for 8 hours to constant weight, and sieve out the compost with a particle size of 1700nm; crush the compost with a particle size of 1700nm at 24000 rpm, Prepare 1200nm, 600nm and 300nm garbage micro-fertilizers;

[0063] (2) On 180g of soil, evenly sprinkle 3g of micro-fertilizer with a particle size of 300nm on the surface of the soil, and finally cover it with 20g of soil evenly;

[0064] (3) sow tall fescue 0.5g then, control temperature is 25 ℃, and relative humidity is 50%, and illumination is the natural light that penetrates into the room;

Abstract

The invention relates to a method for improving the drought resistance of drought substrate tall fescue by adopting urban household fine garbage compost, which comprises the following steps of: respectively scattering fine garbage compost of which the particle diameter is respectively 1200nm, 600nm and 300nm uniformly on the surface of soil, wherein the ratio of the particle diameter to parts by weight of the soil is 1:60-80, the temperature is controlled at 20-26 DEG C, the relative humidity is controlled at 40-60%, and natural light permeating a room is used for illuminating; fully watering at the initial stage of seeding; weighing and watering every one or two days according to 55-65% of field moisture capacity after two weeks to maintain the field moisture capacity in the stress range; and measuring each index from the 44th day. The result shows that under the drought stress, the fine compost increases the biomass of the tall fescue to a certain extent, and the research result of growth of root systems of lawn plants can be basically met by matching the compost with the substrate for cultivating turf.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a reasonable and safe use method for composting municipal domestic garbage. More specifically, a method for improving drought tolerance of tall fescue in arid substrates using fine litter composting. Background technique [0002] Lawn refers to the lawn lawn that is formed by artificial planting of herb plants and artificial transformation of natural grassland, which has aesthetic and ornamental effects, and can be used for people's leisure, entertainment and moderate sports. Fertilization treatment is one of the most important management methods in the lawn maintenance and management system. In order to supplement the shortage of nutrient supply in the lawn soil in time, fertilization is often used to maintain the quality of the lawn at a high level. However, urban artificial turf is not as drought-tolerant as natural grass, especially poor thirst tolerance. The...
