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

[0089] A method for regulating drought-stressed lawn grass protective enzymes by adopting drought-tolerant intensified active nano garbage compost:

[0090] (1) Preparation of nano-compost: dry the domestic waste compost at 105°C to a constant weight, and process and grind the waste compost into 30-35nm nano-compost, which is ready for use;

[0091] (2) Preparation of drought-tolerant microbial agents

[0092] Weigh 10g of the compost sample and place it in a sterile Erlenmeyer flask, add 100mL sterile water and shake it evenly, then take 10mL of the suspension in an Erlenmeyer flask containing 100mL enriched medium, at 28℃, 220r / min Shake culture for 3 days, that is, the mixed microbial flora; the drought tolerance of the mixed microbial flora is enhanced by 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 5% gradient...

Abstract

The invention discloses a method adopting drought-enduring enhancement active nanometer garbage compost for regulating turf grass protective enzyme under drought stress. Appropriate beneficial microbial strains are separated and extracted from domestic garbage compost, an effective microbial agent is obtained by drought-enduring enhancement, and the microbial agent and nanometer garbage compost are jointly applied to a turf medium so as to realize regulate and improve the activity of protective enzyme of the turf grass under drought stress. The experiment result shows that under drought stress, nanometer garbage compost combining with microorganisms is beneficial for the growth of festuca arundinacea, the blade protective enzyme activity is improved, and the adaptive capacity of grains to drought stress is enhanced.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection and relates to a method for adjusting drought-stressed lawn grass protective enzymes by adopting drought-tolerant intensified active nano garbage compost. Background technique [0002] Nano-Science and Technology (Nano-ST) is a new technology that emerged in the late 1980s. It mainly studies structural dimensions in (10 -7 -10 -9 m) The nature and application of substances within the scope. Because nanomaterials have the basic characteristics of interface surface effect, small size effect, macroscopic quantum tunneling effect and quantum size effect, many strange properties that traditional materials do not have appear. Nanomaterials exhibit characteristics different from traditional materials in terms of absorption, catalysis, magnetic effects and sensitive properties. They can be highly intersected with many fields, including physics, chemistry, electronics, materials science and bio...
