Synchronous acer rubrum graftage/cuttage seedling-breeding method

Abstract

The invention discloses a synchronous acer rubrum graftage / cuttage seedling-breeding method. The method comprises the following steps of picking and shearing current branches of acer rubrum and acer saccharinum in autumn, and preparing a cuttage bed for graftage and cuttage; cutting all cuttings below a graftage port into a matrix during cuttage, and filling water and building a small shed on the cuttage bed after the cuttage; performing management after the cuttage; controlling the internal temperature and humidity of the small shed after the cuttage; when the graftage notch is completely healed and adventitious roots cannot grow from the cuttings, removing the small shed covering the cuttage bed, and lightly slicing a graftage notch binding film through a blade; controlling the internal temperature and humidity of a greenhouse; when the rooting percentage reaches 95 percent and the germination rate is more than 85 percent, performing ventilation seedling exercising, and performing transplantation after seedling exercising for 7d. The method has the combined advantages of acer rubrum graftage and cuttage seedling-growing methods, overcomes the defects of the acer rubrum graftage and cuttage seedling-growing methods, is high in breeding survival coefficient, easy and convenient to operate, labor-saving in management and convenient to popularize, is an easy way of quickly breeding the acer rubrum on the premise of keeping the good characteristics of a mother plant, and plays an important role in industrial development, popularization and application of the acer rubrum.

Description

technical field

[0001] The invention relates to a method for raising seedlings by cuttings, in particular to a method for raising seedlings of American red maple by grafting and cutting simultaneously, and belongs to the technical field of plant propagation. Background technique

[0002] American red maple scientific name red maple ( Acer rubrum ), is a world-renowned garden ornamental tree species, and the main varieties are all new horticultural varieties that have been bred after improvement or hybridization. 'Sun Valley', 'Red Dot', 'New Century', 'Autumn Flames', 'Red Guards', 'Autumn Dreams', etc. The coefficient of variation of sowing and reproduction of American red maple is large, and its improved varieties can only retain their excellent characteristics through asexual reproduction.

[0003] At present, there are mainly three ways of breeding American improved red maple in China: tissue culture, cutting and grafting.

[0004] In the process of realizing the pres...
