Problems solved by technology

At present, most of the research on nano-fertilizers is nano-material synergistic fertilizer or nano-material coated fertilizer, but there is no literature report on the research on processing the fertilizer itself to nano-particle size and applying it to lawn plants

Embodiment 1

[0114] A method for improving the drought resistance of field turf production by using drought-resistant enhanced active nano-garbage composting:

[0115] (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;

[0116] (2) Preparation of drought-tolerant microbial inoculum

[0117]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 w...

Abstract

The invention discloses a method for improving the drought resistance of field turf production 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 turf by adopting enhanced drought-resistant microbial agent combined with nanocompost. 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, electronics,...
