Problems solved by technology

When existing sweet-scented osmanthus is grafted, only before grafting, the incision of scion and rootstock is sterilized, and the effect of common sterilizer is poor, after grafting, although wrap tightly with plastic film, before rootstock and scion heal, the thing of bacterial infection Occurs from time to time, resulting in scion rot caused by diseases and insect pests, reducing the survival rate of scion

example 1

[0017] Example 1: a method for grafting and propagating osmanthus osmanthus, it is characterized in that comprising the following steps:

[0018] 1) Selection of rootstock: choose sandy loam soil with deep, fertile and well-drained soil, deep plowing and careful cultivation, and apply 4000 kg of decomposed farmyard manure per mu as base fertilizer. Plants, weeding and watering in time, stop irrigation at the end of August, so that the seedlings will be lignified to survive the winter; pick and choose 3-year-old, strong growth and no pests and diseases, and the thickness of 2.3cm Ziyinggui seedlings as rootstocks;

[0019] 2) Collection and processing of scions: Select the young and mature mother trees with good varieties, luxuriant flowering, strong upper part of the canopy, fully lignified 1-year-old robust, pest-free branches as scions, the scion length is 8-10cm, with 1 leaf and 1 bud; Cut the lower part of the scion into a 2.5cm long wedge-shaped bevel, the bevel is straig...

example 2

[0023] Example 2: According to the grafting propagation method of a kind of Foding osmanthus of example 1, in the operation step 3) when grafting, in mid-April, the rootstock is cut off at a height of 50 cm from the ground at a smooth, node-free trunk. Wrap the wounded surface of the tree trunk with a clean water-absorbent fabric soaked in 800 times of botanical fungicide on the surface and the site to be grafted. After one hour, cut 2-3cm long on the rootstock through the water-absorbent material. The slightly thinner side of the scion is inserted into the interface to align the cambium, wrap it tightly with plastic film, leave a section of water-absorbent fabric outside the plastic film, and put the water-absorbent fabric outside the plastic film into a container containing 800 times of botanical fungicide. In the container, the end of the absorbent fabric reaches the bottom of the container. After the mouth of the container is sealed, the plastic film wraps the exposed absor...

Abstract

The invention discloses a method for growing seedlings and breeding fodinggui grafted, which includes the steps of rootstock cultivation and selection, scion collection and processing, grafting, and post-grafting management. The affinity of the scion improves the survival rate of grafting, shortens the cultivation time, and can bloom in the same year after grafting; the osmanthus fragrans grafting and propagation technology of the present invention has a survival rate as high as more than 95%, is easy to operate, and has a wide market application.

Description

technical field [0001] The invention relates to a technique for raising seedlings of osmanthus fragrans, in particular to a technique for growing seedlings of osmanthus fragrans by grafting. Background technique [0002] Osmanthus fragrans Osmanthus fragrans Oleaceae Oleaceae Osmanthus Osmanthus plant, is one of China's top ten traditional flowers, in China more than 2,500 years of cultivation history. There are many varieties of sweet-scented osmanthus with pleasant aroma. According to the flower color, it can be divided into Luteus group, Albus group, Aurantiacus group and Asiaticus group. Because of its beautiful tree shape, evergreen seasons and fragrant flowers, it is one of the most important garden plants in China. At the same time, sweet-scented osmanthus can also be used to extract aromatic oils and extracts, and the flowers, fruits and roots can be used as medicine. [0003] Osmanthus osmanthus seedlings can be raised by seeds, cuttings, layering, and grafting. H...
