Trichoderma harzianum and application thereof

Abstract

The invention discloses trichoderma harzianum and application thereof, relates to the field of agriculture, and aims to solve the problem of low survival rate of plant cuttage, particularly cornus alba cuttage propagation. The trichoderma harzianum NECC10059 disclosed by the invention is preserved in the China General Microbiological Culture Collection Center (CGMCC), the preservation address is No.3, No.1 yard, Beichen West Road, Chaoyang District, Beijing, the preservation date is July 16, 2015, and the preservation number is CGMCC NO.11122. The trichoderma harzianum NECC10059 disclosed by the invention has the advantages that the preservation number is CGMCC NO.11122; the method is used for promoting growth of plants after cuttage. The trichoderma harzianum disclosed by the invention is beneficial to hardwood cutting propagation of the cornus alba, and the trichoderma harzianum has a promoting effect on the cutting survival rate of the cornus alba and the health of survived plants, so that the trichoderma harzianum has important significance on promoting efficient and economical cutting propagation of the cornus alba by utilizing a trichoderma induction method which is simple and convenient to operate. The method is applied to the field of cornus alba.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a strain of Trichoderma harzianum and its application. Background technique [0002] Cutting propagation refers to: cutting propagation is to take part of the vegetative organs of the plant, insert it into loose and moist soil or fine sand, and use its regeneration ability to make it take root and branch to become a new plant. [0003] Red Ruimu ( Cornus alba ), also known as red stalk wood, is born in miscellaneous forests or mixed coniferous and broad-leaved forests at an altitude of 600-1700 meters (up to 2700 meters in Gansu). The branches and trunks of red Swiss wood are red all year round, the autumn leaves are bright red, the small fruits are white, and the branches are as red as coral after falling leaves. grow plants. Planted alternately with evergreen trees, red and green complement each other, and can be used to arrange large flower beds, flower borders and three-dimensio...

AI Technical Summary

Problems solved by technology

The general cutting method needs to prepare and disinfect the cutting substrate in a certain proportion, and it is necessary to soak the cuttings in a liquid diluted with α-naphthylacetic acid powder, so that cutting red Swiss wood can promote its rooting and improve the survival rate, but this method survives low rate

At present, there are few reports on the use of microorganisms to improve the survival rate of red Swiss wood cuttings and prevent diseases caused by pathogenic bacteria
