Embodiment 1

[0114] A method for improving the drought resistance of field turf production by adopting drought-resistant intensified active nano-waste compost:

[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 use;

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

[0117] Weigh 10 g of the compost sample into a sterile conical flask, add 100 mL of sterile water and shake evenly, take 10 mL of the suspension in a conical flask containing 100 mL of enriched medium, and put it in a conical flask at 28°C and 220 r / min. Shaking culture for 3 days is the mixed microbial flora; the drought tolerance of the mixed microbial flora adopts the method of gradually increasing the concentration of PEG6000. During the strengthening process, depending on the OD 600 Gradually increase the PEG6000 concentration as it grows, the PEG6000 concentration is increased in a gradi...

Abstract

The invention discloses a method for improving the drought resistance of field turf by adopting drought tolerance-reinforced active nanometer waste compost. The method is characterized in that appropriate beneficial microbe strains are separated and extracted from domestic waste compost, drought tolerance reinforcement is carried out to obtain an efficient microbial agent, the efficient microbial agent and nanometer compost are mixed and then are applied to a turf matrix, the drought tolerance of turf plants under drought stress is researched, and bases are provided for application of the nanometer compost combined microbial agent in the drought resistance of turf grass. Experiment results show that nanometer compost combined microbes are helpful for growth of Festuca arundinacea under the drought stress, improve the activity of leaf protection enzyme, enhance the adaptation ability of the plants to the drought stress, and realize the water saving rates under moderate stress and serious stress of 43.10% and 52.39% respectively.

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 using an enhanced drought-resistant microbial inoculant combined with nano-compost. Background technique [0002] Nano-Science and Technology (Nano-ST) is a new technology that emerged in the late 1980s. -7 -10 -9 m) Properties of substances within the scope and their applications. Because nanomaterials have basic characteristics such as interface surface interface effect, small size effect, macroscopic quantum tunneling effect and quantum size effect, many exotic properties that traditional materials do not have appear. Nanomaterials exhibit different properties from traditional materials in terms of absorption, catalysis, magnetic effects and sensitive properties, and can be highly intersected with many fields, including physics, chemistry, electronics, materials science and biology, in high-tech applica...
