Embodiment

[0016] Concrete operation of the inventive method:

[0017] Select rootstock: Use 1-year-old elm seedlings as rootstock, with a ground diameter of 1.0 cm; the seedling trench is 60 cm wide, and the number of seedlings in each trench is relatively large, which is conducive to grafting operations. Cut off the rootstock at 10 cm from the ground before grafting;

[0018] Collection of scions: On March 8th in spring, select 2-year-old branches of Ulmus jinye that are strong, full of spores and full of spores before the sap flows as the mother branches of the scion, and store them at a temperature of 3°C and a humidity of 90%;

[0019] Cut the scion: before grafting, cut the mother branch into 5cm branches to make the scion, with 2 buds; flatten the surface below the back of the bud with a little xylem, and cut the surface with a length of 3cm, and then cut the back of the surface into a small slope less than 1cm long at 45° , so that the lower end of the scion becomes a flat wedge...

Abstract

The invention provides a dwarf ulmus pumila cv.jinye ball grafting and cultivating method. The method is characterized in that dwarf ulmus pumila cv.jinye balls is cultivated through grafting by taking ulmus pumila as the stock and ulmus pumila cv.jinye branches as scions. The method comprises the following steps: pruning all the upper branches (8-10cm above the ground) of the stock before grafting; selecting and intercepting 1-2-year ulmus pumila cv.jinye branches as scion base branches; cutting the standby base branches into 4-6cm branch sections as scions with 1-2 buds before grafting; chopping slopes with few xylems below the backs of the scion buds and then chopping 45-degree small slopes corresponding to the slopes on the backs of the slopes so that the lower ends of the scions are in flat wedge shape, wherein the slopes are 2-3cm long and the length of the small slopes is less than 1cm; selecting the smoother side of the stock and using a grafting knife to cut the cross sectionof the stock in the vertical direction, wherein the grafting knife clings to the xylems and is provided with few xylons and the length of the cuts is 2-3cm and is equal to that of long slopes of the scions; inserting the scions into the cuts of the stock quickly, wrapping the scions with the cut skins of the stock and sealing and binding the top planes of the scions with plastic film tapes after grafting; carrying out transplanting after the scions survive after grafting, carrying out field planting and leaving 2-3 plants in each hole, wherein the hole spacing is 1.0m and the line spacing is 1.2m; and forming the dwarf ulmus pumila cv.jinye balls after carrying out repeated pruning 6-7 times.

Description

technical field [0001] The invention relates to the grafting and cultivation of the golden-leaf elm, especially for the dwarf golden-leaf elm. The golden-leaf elm ball obtained by the method has a very high ornamental value, dwarfs the tree body, shortens the ball forming time, and realizes large-scale planting has become a reality. Background technique [0002] The cultivation of shrub-type Ulmus aureus is mainly based on bud grafting, split grafting, and skin grafting. The cutting method is used in high grafting, but it is reported that the survival rate of grafting with skin grafting is the highest, up to 90%. Literature search disclosure: (1) Xin Guoyan of the Bureau of Agriculture, Forestry and Water Conservancy of Zhanhe District, Pingdingshan City, Henan Province published "Chinese Golden Leaf Elm Cultivation Technology" in Beijing Agriculture. 2007(2).-17-18. Purpose. The grafting time is in the middle of March. It is most suitable when the sap will start to flow ...
