A kind of pruning and shaping method of red Sydney pear

Abstract

The invention discloses a red snow pear pruning and shaping method. The pruning and shaping method comprises the following steps that 1, according to the site type, the tree form structure is determined; 2, the distances and distribution of branch groups are adjusted; 3, light transmission treatment and ventilation treatment are conducted; 4, different branches are pruned. The invention provides the targeted red snow pear pruning and shaping method. By determining the tree form structure according to the site type, scientifically adjusting the distances and distribution of the branch groups and guaranteeing light transmission and ventilation in cooperation with pruning of the different branches, an obtained red snow pear tree form is compact, the branch groups are reasonably distributed, not only is space effectively used, but also a fruit tree obtains most suitable growth space furthest, light transmission and ventilation are achieved, and on the basis that the fruit setting rate is effectively improved, the quality of red snow pears is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of red Sydney cultivation and management, and in particular relates to a pruning and shaping method for red Sydney. Background technique [0002] Weishan Red Sydney is a late-maturing pear variety unique to Weishan, commonly known as "Winter Sydney". It grows in high-altitude mountainous areas and mid-level areas. It has wide adaptability, strong tree vigor, and strong stress resistance. It is famous for its bright, translucent, rouge-colored fruit, fine texture and juicy, sweet and easy to store, and it has won the first place in Yunnan high-quality late-ripening pear for its freshness, beauty, fragrance and sweetness. Weishan Hongxue pear is resistant to storage, with regular, large fruit, bright color, sweet and crisp, and high water content, so it has received more and more love and attention. [0003] However, in the process of planting and management of red Sydney, the problem of pruning and shaping i...

Problems solved by technology

[0003] However, in the process of planting and management of red Sydney, due to the long growth cycle of red Sydney, the problem of pruning and shaping is particularly prominent

There are many existing research reports on pear pruning and shaping, but pruning Red Sydney according to the pruning theory in the prior art, the effect obtained is disappointing, and there are many problems, not only the fruiting rate is low, the fruit quality is poor, and The canopy is closed, the light transmission is poor, and the space utilization is extremely unreasonable, resulting in difficult management, high production costs and low economic benefits.
