Seedling cultivation method for forestry ornamental trees

Abstract

The invention discloses a seedling cultivation method for forestry ornamental trees, and belongs to the field of ornamental crabapple cultivation. The seedling cultivation method for forestry ornamental trees comprises the following operation steps that S1, bud grafting is carried out on cultivated crabapple varieties in the first ten days of September to the middle ten days of October of the first year to obtain grafted seedlings; S2, in spring of the second year, the grafted seedlings are planted in a large field; S3, later-period management is carried out after grafted seedling buds germinate; S4, the grafted seedlings are transplanted in the third year; S5, trunk determination is carried out according to the cultivation target, and crabapple seedlings are obtained; S6, the transplantedcrabapple seedlings are watered every day within one week and are watered once every week after one week; S7, field management is carried out on the crabapple seedlings; and S8, when the ground diameter of the crabapple seedlings reaches 3-4 cm in the fourth year, the crabapple seedlings can be taken out of a garden. According to the method, under the condition that the cost is not increased, thegrowth characteristics of trees are fully utilized, so that the cultivated seedlings are straight in trunk shape, consistent in height and full in crown shape, and the quality and outplanting rate ofthe seedlings are greatly improved.

Description

technical field [0001] The invention relates to the technical field of ornamental crabapple cultivation, in particular to a method for cultivating seedlings of forestry ornamental trees. Background technique [0002] Begonia is the general name and common name for several plants of the genus Apple and several plants of the genus Papaya. The representative plants Begonia and papaya are both shrubs or small trees in the Rosaceae family. They are famous ornamental tree species in China. They are commonly cultivated in various places. Petals and white double petals, Begonias are mostly ornamental flowers and trees used for urban greening and beautification, many of which are famous ornamental plants, such as: Xifu Begonia, Hanging Begonia, Sticking Begonia and Papaya Begonia, commonly known as "Begonia "Sipin" is an important flowering tree in the temperate zone, and its seedlings are not strong in trunk, but at present, in the cultivation process of crabapple seedlings, the phe...

In the prior art, artificial auxiliary poles are used. method to straighten it, but the cost of this method is relatively high, which greatly increases the cost of seedling cultivation
