Embodiment Construction

[0012] The following embodiments of the present invention are implemented under the climatic conditions in North China. Under the climate conditions that are obviously different from those in North China, the implementation should be appropriately advanced or postponed.

[0013] The embodiment of the present invention is a composite molding method of Chinese golden leaf elm (Ulmus elm). The specific method is as follows:

[0014] (1) Planting of Ulmus chinensis seedlings of different specifications: After the soil thaws in spring and the sap starts to flow, dig planting holes according to the distance between plants and rows of 2 meters * 2 meters; plant 4 selected plants of Ulmus chinensis in each planting hole, and measure their height Trim to 80cm, 130cm, 180cm, 230cm;

[0015] (2) Composite planting: Combine several plants of Ulmus sinensis with different fixed stem heights and plant them together, and select the tallest one as the main trunk for cultivation, which is use...

Abstract

The invention relates to a compound modelling method of ulmus pumila cv.jinye. The method comprises (1) selection of nursery stocks of different specifications; (2) compound planting; (3) approach grafting; (4) forming and fixing of lateral branches; and (5) modelling and pruning. By adopting the method, not only can the aims of easiness in pruning and forming in the same year be reached, but also the modelling speed is high and ulmus pumila cv.jinye can be formed and come into the market in the same year, thus reducing the cost and expenses.

Description

technical field [0001] The invention relates to the field of nursery stock growth management, in particular to a composite modeling method of Chinese golden leaf elm, also known as beautiful elm. Background technique [0002] The traditional modeling technique of Chinese golden leaf elm adopts the combination of grafting and pruning. The method is to choose a white elm with a certain shape height of more than 3 cm as the rootstock, and connect two scions at intervals on the trunk. The disadvantages of adopting this method for molding are weak growth, slow molding speed, and great influence on the survival rate of grafting. It takes 1-2 years to cultivate finished seedlings of Ulmus chinensis by using the above molding technology, which is time-consuming, labor-intensive and material-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a method suitable for composite molding of Ulmus chinensis, which can not only achieve the purp...
