Acer platanoides variety interspecific grafting method and application thereof in preventing insect pests

Abstract

The invention provides an acer platanoides variety interspecific grafting method. Acer truncatum seeds are adopted for sowing, and seedlings of the acer truncatum seeds are reserved for use when growing to be biannual and triennial seedlings; from February to March, annual or biannual branches are cut off from strong adult acer platanoides trees which grow robustly, leafbud shoot sections with full growth and development are cut off, and preserved at 10-20 DEG C for use; from March to April, leadbuds with full growth and development of acer platanoidess are subjected to low-position grafting to stocks of biannual and triennial seedlings of acer truncatum which are ready for use through a bark graftage method; field careful maintenance management is conducted on acer platanoides variety interspecific grafted seedlings, and acer platanoides variety interspecific grafting is completed as long as the normal and healthy growth and development are guaranteed. According to the method, acer truncatum, acer mono Maxim. and other Chinese maples which are immune or highly-resistant to two species of anoplophora macularia and have compatibility are utilized as the stocks for grafting, the insect resistance of acer platanoides fine varieties to the two species of anoplophora macularia can be improved, and the damage degree of the two species of anoplophora macularia to a series of acer platanoides fine varieties can be reduced.

Description

technical field [0001] The invention belongs to the technical field of biological breeding of forest trees, and relates to the insect-resistant breeding of maple interspecies grafting, in particular to improving the insect resistance of Norway maple fine variety series to bald beetle and star beetle. Background technique [0002] There are more than 200 species of maple trees in the world, which are widely distributed in the northern temperate zone and tropical mountains, and are distributed in Asia, Europe and North America. There are more than 150 species in my country. It is a country with concentrated maple distribution and rich resources, and is the modern distribution center of maple trees in the world. [0003] According to the destructive damage to North American maple trees and the difficulty of control caused by the invasion of North American and European countries by the bald beetle and the long beetle in the past 20 years, and the North American maple trees intro...
