Abstract

The invention provides a pear tree two-arm direct-motion type shed frame tree shape which comprises a tree trunk. The tree trunk has two boughs which grow in a direct-motion mode, and base angles of the two boughs are 45 degrees. When reaching a frame-climbing point, the boughs are fixed on a horizontal shed frame in a direct-motion mode, and extended long branches of the boughs are guided onto an elevation guide line in a perpendicular mode. The boughs have long placed fruit branches which are arranged in parallel and vertically extend into intervals. Before the two boughs climb a frame, two horizontal robust side position branches which are pulled along the reverse direction to be parallel to the boughs after the horizontal robust side position branches grow upward to the frame face. The side position branches have F-shaped single-shaft long placed type fruit branches which are arranged in parallel and vertically extend to the intervals. The tree shape only has the two boughs, and therefore the problems that an inclined crown appears easily in a three-bough tree shape and the main boughs intersect are solved. The two boughs oppositely extend in a direct-motion mode and do not influence each other. The two-bough tree shape is easy to reshape, and the two boughs are easy to form after the trunk is fixed. The phenomenon of lack of branches appears in a three-bough shed frame due to the fact that sprout force of a pear tree is weak. The three shape has the advantages that cultivation density is high, early-stage output is high, light conditions are good, the branches are easy to arrange in an ordered mode, uniformity of fruit quality is high, and standardization is easy to achieve.

Description

technical field

[0001] The invention belongs to the fields of fruit tree cultivation and fruit tree ecology, and in particular relates to a pear tree scaffolding tree shape and a shaping and pruning method thereof. Background technique

[0002] Trellis cultivation is the main method of pear cultivation in Japan and South Korea. my country has introduced related cultivation techniques from Japan in the 1990s. At present, trellise pear cultivation has been carried out in Jiangsu, Shandong, Zhejiang and other provinces. Practice has proved that the scaffold-shaped tree shape not only has the advantage of wind resistance, but also has incomparable advantages in improving fruit quality, especially the uniformity of the fruit, and is an important way of high-quality and standardized cultivation. . With the improvement of people's consumption level, trellis cultivation has become an inevitable choice for high-quality pear cultivation. On the other hand, the aging problem of my co...

Embodiment Construction

[0055] The varieties tested in the present invention are Cuiguan and Huanghua, and the tree shape of the "double-arm antegrade" scaffolding was carried out, and the tree shape of the conventional three-main-branch scaffold was used as a comparison.

[0056] The "two-arm forward" scaffolding pear-shaped plastic method is a utility model patent applied on the same day - a new type of improved pear tree flat scaffolding (that is, "three lines on one side" or "two lines on one side" supporting) tree shape. The pear tree "double-arm forward" scaffold tree shape adopts a scaffold with a height of 1.7-1.8m, a trunk height of 1.2-1.3m, 2 main branches, and the second main branch is 50cm away from the scaffold surface, without a central trunk. The two main branches are cultivated in the forward direction, so it is called the "double-armed forward" trellis tree shape. The cultivation density adopts "wide plant and narrow row", and the spacing between plant and row is 4m×3m. There a...
