Problems solved by technology

However, most of the literature is directly using the developed nano-materials to study the impact on crops. There is no literature that actually uses nano-technology to process garbage compost to the nano-level to make nano-fertilizers and apply it to the study of plant drought resistance. to report

Embodiment 1

[0094] A method for improving the drought resistance of turfgrass by using drought-resistant enhanced active nano-garbage composting, characterized in that it is carried out according to the following steps:

[0095] (1) Preparation of nano-compost: Dry the domestic waste compost at 105°C to constant weight, process and grind the waste compost to make 30-35nm nano-compost for later use;

[0096] (2) Preparation of drought-tolerant microbial inoculum

[0097] Weigh 10g of the compost sample and place it in a sterile Erlenmeyer flask, add 100mL of sterile water and shake it evenly, then take 10mL of the suspension in a Erlenmeyer flask containing 100mL of enrichment medium, at 28°C, 220r / min Shaking culture for 3 days is the mixed microbial flora; the drought tolerance enhancement of the mixed microbial flora adopts the method of gradually increasing the concentration of PEG6000. During the strengthening process, depending on the OD 600 Increase and gradually increase the conce...

Embodiment 2

[0111] The method of improving the drought resistance of turfgrass by using drought-resistant enhanced active nano-garbage composting:

[0112] (1) Preparation of nano-compost: Dry the domestic waste compost at 105°C to constant weight, process and grind the waste compost to make 30-35nm nano-compost for later use;

[0113] (2) Preparation of drought-tolerant microbial inoculum

[0114] Weigh 10g of the compost sample and place it in a sterile Erlenmeyer flask, add 100mL of sterile water and oscillate evenly, then take 10mL of the suspension in a Erlenmeyer flask filled with 100mL of enrichment medium, at 28°C, 220r / min Shaking culture for 3 days is the mixed microbial flora; the drought tolerance enhancement of the mixed microbial flora adopts the method of gradually increasing the concentration of PEG6000. During the strengthening process, depending on the OD 600 Increase and gradually increase the concentration of PEG6000, the concentration of PEG6000 increases with a grad...

Abstract

The invention discloses a method for improving the drought resistance of turfgrass by adopting drought-resistant enhanced active nano-garbage composting. It isolates and extracts suitable beneficial microbial strains from domestic waste compost, obtains more efficient microbial agents through drought tolerance enhancement, applies them to lawn substrates in combination with nano-compost, and studies its effect on lawn plants under drought stress. Drought tolerance provides a basis for the application of nanocompost combined with microbial agents in the drought resistance of turfgrass. The experimental results show that under drought stress, nano-compost combined with microorganisms can help the growth of tall fescue, improve the activity of leaf protective enzymes, and enhance the adaptability of plants to drought stress. Under moderate stress and severe stress, the water saving rates are respectively 43.10% and 52.39%.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a method for improving the drought resistance of turfgrass by adopting enhanced drought-resistant microbial agent combined with nanometer compost. Background technique [0002] Nano-science and technology (Nano-ST) is a new technology that emerged in the late 1980s. It mainly studies the structural scale in (10 -7 -10 -9 m) The properties and applications of substances within the scope. Because nanomaterials have basic characteristics such as interface surface interface effect, small size effect, macroscopic quantum tunneling effect and quantum size effect, there are many strange properties that traditional materials do not have. Nanomaterials exhibit characteristics different from traditional materials in terms of absorption, catalysis, magnetic effects, and sensitive properties, and can be highly intersected with multiple fields, including physics, chemistry, e...
