Embodiment

[0041] 1. Plant material

[0042] 1.1 Rootstock

[0043] Malus robosta, also known as Huailai Begonia and Haihong, belongs to the Rosaceae (Rosaceae) subfamily Maloideae (Maloidae), a small deciduous tree of the genus Malus, and is a species of Begonia in Xifu. The eight-edged begonia is native to Huailai County, Hebei Province, and has a long history of cultivation. Because of the flat shape of the begonia fruit and the obvious eight-rowed begonia around it, it is named "Eight-edged Begonia". Eight-row Begonia seedlings have developed root system, more fibrous roots, strong seedlings, cold resistance, drought resistance, waterlogging resistance, salinity resistance, disease and insect resistance, barren resistance, water and humidity resistance, and are suitable for all kinds of soil. % normal growth in soil. Long lifespan, under normal management, the root lifespan is more than 180 years.

[0044] The rootstock material used in this patent is the seedlings of Begonia occi...

[0072] Grafting Survival Rate

[0073] In the past 3 years, we have carried out 4 times of grafting and propagation experiments of rowan trees. As can be seen from Table 1, with Begonia occidentalis as the rootstock, all the rowan trees were successfully grafted, and the overall average survival rate was 78.3%, and the survival rate of the improved split grafting method was better than the budding grafting. This result shows that: there is a strong affinity between rowan tree and Begonia, and it is feasible to graft rowan tree with Begonia as rootstock.

[0076] Growth of grafted seedlings

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

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 a rowan tree. Background technique [0002] Rowan tree (Sorbus pohuashanensis (Hance) Hedl.), also known as Rowan, is a small deciduous tree of the genus Sorbus in the Rosaceae (Rosaceae) apple subfamily (Maloideae), and is a unique native tree species in my country. Rowan tree is an important tree species for viewing leaves, flowers and fruit. It has beautiful tree shape, tender green feather leaves in spring, silver flowers in early summer, beautiful feather leaves in summer, red leaves and red fruits in autumn, and has a very high garden ornamental value. . Rowan is highly resistant to a variety of harmful gases (such as SO 2 , SO 3 , CO 2 etc.) has strong resistance, is 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 biodivers...
