Problems solved by technology

[0009] The main tree shape of the imported Japanese scaffolding in my country is mainly the split-shaped tree shape. Judging from the current production situation of the imported tree shape, the pruning of the tree shape is complicated, and the problem of branch structure confusion often occurs on the shed surface. On the one hand, because Pear tree trellis cultivation technology is still in the demonstration and promotion stage in my country. On the other hand, farmers do not know how to comprehensively use techniques such as pruning, water, and fertilizer to control tree vig

Embodiment 1

[0027] Embodiment 1 Horizontal scaffold construction

[0028] 1. The structure and material specifications of the scaffolding

[0029] Such as figure 1 As shown, the structure of the entire scaffold is composed of columns and mesh parts. The columns are made of cement prefabricated materials and metal galvanized material columns. According to their positions and functions, they are divided into corner columns 1, side columns, columns 4 and ground anchors 5 .

[0030] Corner column 1: For the four corners of the scaffold, use galvanized steel pipe with a diameter of Φ70mm, a length of 4m, and a wall thickness of more than 4mm;

[0031] Side columns: erected around the scaffolding, including cement columns 2 and metal galvanized pipes 3, the cement columns 2 are cement poles of 10cm×10cm×285cm; the metal galvanized pipes 3 are diameter Φ70mm, length 2.2-3.7m, Galvanized steel pipe with a wall thickness of 4mm or more. Cement columns 2 and metal galvanized pipes 3 are arr...

Embodiment 2

[0054] Example 2 Seedling planting and pruning

[0055] 1. Species and seedling requirements

[0056] Variety requirements: moderate tree vigor, slightly soft branches, more than 55% of branches, more than 8% of annual branch axillary flower buds, and continuous fruiting ability of short fruiting branches for more than 3 years. In this example, Su Cui No. 1 pear is selected as a 1-year-old land-bearing pear Grafted seedlings, in the actual production process, you can choose Sucui No. 1, Sucui No. 2, Fengshui, Yuanhuang, Xingao and other pear varieties;

[0057] Seedling requirements: the grafted seedlings are not less than 1.2m in height, not less than 3 lateral roots, the length of each lateral root is not less than 20cm, and there are 2 to 3 full buds in the plastic belt between 1.2-1.8m , the grafting joint at the root is completely healed, and the diameter of the stem at 10 cm above the grafting joint is at least 1 cm;

Embodiment 3

[0066] Example 3 Comparison of 5 tree shapes on tree growth, fruit quality and yield

[0067] (1) Test material

[0068] The test site is located in the demonstration garden of the Plant Experiment Base of Jiangsu Academy of Agricultural Sciences in Lishui, Nanjing. The soil is mainly yellow-brown loam, which is relatively barren. The tested variety is "Sucui No. 1", which was planted in 2009 with one-year-old ground-grafted seedlings. The seedling height is 1.5m, with 3 lateral roots and a seedling diameter of 1.2cm;

[0069] The experimental group adopts the one-sided tree shape obtained by seedling planting and shaping and pruning methods described in Example 2, with a row spacing of 4m × 4m;

[0070] The control group adopts the conventional tree shape introduced in the background technology respectively, wherein the control group 1 is a horizontal shape, the control group 2 is a funnel shape, the control group 3 is a split shape, and the control group 4 is a cup sha...

Abstract

The invention discloses a method for shaping shed pears in a pear garden. The method comprises the steps of building a shed frame in the pear garden in which the shed pears are planted and is characterized in that the tops of grafted seedlings are cut, wherein branches close to the cut tops are diagonal branches, side branches are reserved on the diagonal branches at intervals, each side branch is matched with 2-3 auxiliary side branches in an alternate way, and all elongated heads on a trunk and the side branches of the diagonal branches grow upwards at the angle of 45 degrees; a vertical fixed rod is arranged at the root of each trunk of each grafted seedling, and an upper shed guide rod is away from each fixed rod by 1.5m; the first bud branches and the second bud branches on the tops are vertically upwards bond by the vertical fixed rods, and all the tips are twisted when the buds germinated at the lower parts of the diagonal branches grow to the period of half lignification; in winter, the second bud branches on the tops are pruned from the roots, and the bud branches at the first bud cuts are bond on the upper shed guide rods along the reverse direction to form a tree-shaped structure leaning to one side. The main branches, the side branches and the auxiliary side branches are reasonably configured, so that the method is less in trimming work and easy to master; the trimmed tree structure is simple, the early yield is high, and the method is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, in particular to a method for shaping pears on a scaffold in a pear orchard. Background technique [0002] Modern pear scaffolding cultivation technology originated in Japan. Pear tree scaffolding cultivation can reduce the losses caused by typhoon attacks, facilitate daily management of orchards, high yield per unit area, and good quality pear fruit. The traditional pear tree cultivation method in my country is the standing tree type In 1995, Dalian City was the first to introduce the Japanese pear trellis cultivation technology. According to incomplete statistics, there are about 100,000 hm of scaffolding pear orchards in my country 2 , mainly distributed in Shandong, Liaoning, Hebei, Zhejiang, Jiangsu, Shanghai, Fujian, Jiangxi and other eastern coastal or offshore provinces and cities, and a small amount of planting in Hubei, Henan, Anhui, Sichuan and other provinces.
