Embodiment Construction

[0016] The seedling raising method of dwarf pear tree may further comprise the steps:

[0017] 1. Cultivate root stock seedlings: collect deep-rooted and luxuriant leaves, moderate age, and mature sorrel fruit seeds without pests and diseases. After sand culture to accelerate germination, sow the grown seedlings as root stocks;

[0018] 2. For the cultivation of the dwarfing middle stock, use Sorbus pear as the female parent, and Huagai pear and Nanguo pear as the male parent to carry out artificial interspecific hybridization. The flowers of Huagai pear and Nanguo pear are collected when they are open, and the mature pollen of the two is collected for fertilization. On the pistil stigma of the female parent of the pear, in order to prevent self-pollination, the stamens of the female parent are removed first, and bagged, and the hybrid saplings come out after the obtained seeds are sown, that is, the dwarf intermediate stock saplings are bred;

[0019] 3. Scion, when selecting...

Abstract

The invention relates to fruit tree grow seedling fields, more specifically it discloses a nursery method of dwarfing pear trees which includes raising rootstock, dwarfing interstock and scion. The main technology is said rootstock use the seedling of wild-anvil pear seeds as the root grafting, said dwarfing interstock is hybrid, that is manual crossing between the wild pears as female parent line and the Huagai pears and the Nanguopears which are paternal, the hybrid sapling raising from the hybrid seeds is used as the dwarfing interstock, said scion is the dwarfing interstock is grafted on the rootstock (seedling) as the scion, then the dwarfing pear trees are raised. The affinity between the rootstock and the graft is strong in the invention, tree bodies' compact, fruiting early, crop high, cold resistant, disease resistant, easy management, convenient management and it is suitable for landscaping, greening and potted plants in rural and urban.

Description

technical field [0001] The invention relates to the field of fruit tree seedling cultivation, more specifically, it relates to a method for raising seedlings of dwarf pear trees. Background technique [0002] At present, in the seedling raising process of dwarf pear trees, dwarf saplings with arborization stock are generally used. The seedling raising method of this dwarf pear tree is: at first cultivate seedlings after sowing with wild sorbus seeds, and use them as crop grafting dwarf pear trees. The root stock of the tree, according to the procedure of fruit tree grafting, and then on the root stock seedlings, a pre-selected dwarf pear tree is grafted as a scion (such as Nanguo pear). After the buds of the scion germinate, the arborization stock is cultivated Dwarf saplings, cultivated arborization stock dwarf saplings, its bottom is a seedling root stock, and the top is a dwarfing scion, cultivating this dwarfing pear seedling, there are many d...
