Embodiment

[0041] 1. Plant material

[0042] 1.1 Rootstock

[0043] Malus robusta, also known as Huailai crabapple or Haihong, is a small deciduous tree of the Rosaceae subfamily Maloideae and the Xifu crabapple species. The eight-edged crabapple is originally produced in Huailai County, Hebei Province. It has been cultivated for a long time. Because the crabapple fruit is flat and surrounded by obvious eight-edged ridges, it is named "Balonged crabapple". Octagonal Begonia saplings have a well-developed root system, more fibrous roots, strong seedlings, cold resistance, drought resistance, waterlogging resistance, salt-alkali resistance, disease and insect resistance, barren resistance, water and humidity resistance, and are suitable for all kinds of soil. % normal growth in the soil. Long lifespan, under normal management, the lifespan of the root system is more than 180 years.

[0044] The rootstock material adopted in this patent is 1-2 years old, with a ground diameter of 0.8cm-1...

[0072] Grafting survival rate

[0073] In the past 3 years, we have carried out 4 experiments on the grafting and propagation of rowan trees. It can be seen from Table 1 that all Sorbus trees were grafted successfully with the rootstock of Begonia chinensis, the overall average survival rate was 78.3%, and the survival rate of improved split grafting was better than chip bud grafting. This result indicated that there was a strong affinity between Sorbus and Begonia, and it was feasible to graft Sorbus with Begonia as rootstock.

[0075]

[0076] Growth of grafted seedlings

[0077] Since 2015, the inventor has observed the plant height and base diameter annual growth of the grafted seedlings of the above-mentioned rowan tree, and the results show that the annual growth of the grafted rowan seedlings of the rowan tree is above 96cm, and the base diameter annual growth is between More than 1.5cm. The plant height and base d...

Abstract

The invention relates to the technical field of plant propagation, in particular to a Sorbus pohuashanensis grafting method. The grafting method uses Malus robusta as stocks, and uses the Sorbus pohuashanensis as scions to perform grafting. The problem that the Sorbus pohuashanensis is difficult to sow and propagate and is low in the rooting and survival rate of cuttage propagation can be solved.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a method for grafting rowan trees. Background technique [0002] Sorbus pohuashanensis (Hance) Hedl., also known as Sorbus pohuashanensis (Hance) Hedl., is a deciduous small tree of the Rosaceae (Rosaceae) Maloideae (Maloideae) Sorbus genus (Sorbus), and is a unique native tree species in my country. Sorbus tree is an important tree species for viewing leaves, flowers and fruits. It has a beautiful tree shape, green feather leaves in spring, silver flowers in early summer, beautiful feather leaves in summer, red leaves and red fruits in autumn, and has very high garden ornamental value. . Rowan has strong resistance to various harmful gases (such as SO 2 , SO 3 , CO 2 etc.) have strong resistance, are very suitable for urban landscaping and air pollution control, and can improve the overall ecological quality of the city; rowan can also attract birds and improve bio...
