Embodiment 1

[0026] spring grafting

[0027] Cut off the rootstock at about 6cm from the ground, and flatten the section. On this incision, use a cutting knife to cut vertically or slightly inwardly with the xylem in the cortex to a depth of about 3cm. Choose a scion that is equal to or slightly smaller than the rootstock, and cut off the branch at the opposite side of the bud section and the lower part of the bud 3cm, so that the incision becomes a 30-degree slope, then reverse the branch, align it with the original cut surface, and cut off 2cm with the xylem slightly , the cutting surface must be flat, then cut off the scion at 2cm above the bud, and insert it into the rootstock immediately. The cambium of the two must be aligned on one side, and then wrapped with a 3cm wide film band. Bandage from bottom to top until the top of the rootstock is wrapped tightly without leaving any gaps, so as to prevent the sap from flowing out and affect the survival. Then reverse the film head to cover...

Embodiment 2

[0029] Grafting in autumn.

[0030] Choose a straight side to cut the cortex at the belly of the rootstock about 8cm from the ground or higher. Select ear size according to rootstock size, make rootstock cut surface coincide with scion cut surface, beveled into the beveled surface of 45 ° angle forward at about 1cm place under bud. Then turn the flat side of the scion upwards, and cut off the cortex from the vicinity of the bud point forward. The cut surface is required to be smooth and just reach the cambium. Finally, turn the scion sideways, and the bud point is upward. The slope of the knife edge is 60 at about 0.5cm above the bud point. Cut it off at an angle of °, insert the scion back into the bottom of the mouth and insert it tightly, so that the cut surface is not exposed, it is better not to insert wrinkled scion, and not to break the cortex of the rootstock. Bind it with clean plastic film and fold the film strip into small strips first. , first tie a circle in the ...

Abstract

The invention relates to a large-scale grafting production method of a woody flower for a garden, particularly relates to a method for grafting michelia champaca in a top grafting manner by using michelia chapensis dandies as parental stocks, and belongs to the technical field of the production of plants for seedling gardens. The method comprises the following step of grafting in spring or autumn by using the michelia chapensis dandies as the parental stocks and using the michelia champaca as scions. The michelia champaca which is a deciduous tree is grated by using the michelia chapensis dandies which are evergreen trees of the magnoliaceae as the parental stocks; the transplanting survival rate is high; the tree vigor recovers quickly. The increments of shoots of grafted nursery stocks can be generally up to 30cm to 40cm in the same year, and the heights of seedlings are up to 80cm to 120cm in the winter of the next year.

Description

technical field [0001] The invention relates to a large-scale grafting production method of garden woody flowers, in particular to a method for high-grafting magnolia japonica with Lechang michelia as rootstock, and belongs to the technical field of seedling garden plant production. Background technique [0002] Michelia chapensis Dandy (Michelia chapensis Dandy) is an evergreen tree of the genus Michelia magnolia. It is native to Guangdong. It likes a warm and humid climate. The optimum growth temperature is 15-32°C. It is reported that it can withstand high temperatures of 41°C. Actually, it is grown in Wuhan. The performance of the region shows that its growth performance is not good in a high temperature environment above 40°C, and symptoms such as tree vigor decline, wilting branches, and scorched leaves appear. Yellow magnolia has strong resistance to harmful gases such as sulfur dioxide and chlorine, so it has good application value. Contents of the invention [00...
