Embodiment 1

[0029] The types of wood rot fungi in maple poplar trunk caves controlled by this embodiment are Deuteromycota and Hyphospora fungi, specifically non-basidiomycota Deuteromycota, Trichoderma spp. 3 strains of the phylum Mycobacteria and Penicillium spp. In this example, the strain numbered 1 belongs to the fungus species of the genus Trichoderma, and the strains numbered 2, 3 and 4 all belong to the fungus species of the genus Penicillium.

[0030] The application of control technology is best carried out when the sap stops flowing, that is, after the leaves fall in autumn, it is appropriate to advance in the early spring of the next year.

[0031] The succession analysis of the microbial groups in the trunk cavity (living standing wood) of the ancient maple poplar tree found that the bacteria first infect the woody parenchyma of the trunk, followed by the bacteria infecting four wood-rot fungal strains (Trichoderma spp. ) 1 strain, Penicillium spp. 3 strains). Therefore, th...

Abstract

The invention discloses a method for preventing wood rotting fungus inside ancient Chinese ash trunk rotten cave. For an ancient Chinese ash whose trunk has rotten caves running through from the top down, people cannot get inside the caves in the trunk for implementing technical operations such as scraping the rotten woodiness, sterilizing and printing edible vegetable oil protecting layer; the invention is aimed at the features of the caves and the types of the pathogenic bacteria strains, employs a prevention method of sensitive agents and concentration, takes 80% of carbendazim wettable powder, 70% of mancozeb wettable powder and 30.5% of thiram wettable powder as a fungicide; and the growth inhibition effect to certain mycelia belonging to the deuteromycota and hyphomycetales fungus that rots the trunk of the ancient Chinese ash is up to 88.23% to 100%. The provided prevention method is cheap in medicine cost, convenient in operation, is able to effectively prevent the caves in the trunk of the ancient Chinese ash from being further rotted, and is beneficial to scientifically protecting the ancient Chinese ash species in our urban and garden cultural heritage.

Description

technical field [0001] The invention relates to the prevention and protection technology of wood-rotting fungus species corrosion caves in the trunks of ancient maple poplars, in particular to the prevention and control method of wood-rot fungus species corrosion caves whose trunks are vertically penetrating. Background technique [0002] Ancient trees are the objects of protection and management in cities in our country. Maple poplar is a common tree species in ancient trees (Pterocaryastenoptera C.DC), and maple poplar is also the main ancient tree species in garden cultural heritage (such as Suzhou World Cultural Heritage Garden-" There are 7 ancient maple and poplar trees in the "Humble Administrator's Garden", accounting for nearly 1 / 3 of the number of ancient trees in the Humble Administrator's Garden). The trunks of ancient maple poplar species are easily corroded by wood rot fungi, resulting in hollow trunks. Due to the variety and complexity of wood rotting fungi, ...
