Problems solved by technology

However, a large number of short cuts violate the biological characteristics of pear trees, and most of the tree body nutrition is consumed in nutrition; secondly, there are many shoots on the tree, and due to the short cuts, the buds below the cut will be stimulated to germinate in large numbers, causing the canopy to be dense. close

Embodiment 1

[0019] A novel pear tree simplified pruning method comprises the following steps:

[0020] (1) When pruning in the first winter, the growing branches of annual pear trees with a height of 60 cm or more are slowly released without pruning, and the remaining upright or space-free branches are removed, and the slow-released pear tree developing branches grow into flowering branches through growth;

[0021] (2) When pruning in winter in the second year, cut off one-third of the pear tree flower branches above 60cm, and keep more than 12 flower buds, and cut off half of the flower branches of 50-60cm, and keep 6-7 Flower buds, 40-50cm string flower branches cut short three-quarters, keep 2-5 flower buds, all string flower branches below 40cm are thinned out;

[0022] (3) When pruning in the winter of the third year, after fruiting, the stringed branches of the pear tree have different numbers of auxiliary branches. Depending on the space of the stringed flowering branches, 1-2 stro...

Abstract

The invention discloses a novel pear tree simplifying and pruning method. The novel pear tree simplifying and pruning method comprises the following steps: keeping flowers and fruits on strong and prosperous developmental branches, thinning weak branches below the trunk; removing fruits on branch group by fruits on strong and prosperous branches; slowly releasing the development branches and not cutting off the kept development branches. According to the simplifying and pruning method disclosed by the invention, the development branches with strong growth trend are used to occupy space, the fruits on the strong and prosperous developmental branches are kept on the main and side branches and the side lateral branches, the excessive weak branches are removed, so that the nutrients are relatively concentrated, the kept development branches are converted into string-flower branches through growth, ineffective branch quantity is reduced, the concentrated nutrients are supplied for the growth of the development branches, the quantity and the quality of the flower buds are improved, the unit fruiting capacity is strengthened, the high yield and the excellent quality are achieved; meanwhile, the novel pear tree simplifying and pruning method is simple and convenient in operation technology, saves much labor power and improves labor efficiency.

Description

technical field [0001] The invention belongs to the technical field of fruit tree shaping and pruning, and in particular relates to a novel simplified pruning method for pear trees. Background technique [0002] The pruning of pear trees was popularized in the 1950s. It is characterized by pruning while maintaining its structural characteristics under a stable tree frame. New trees are planted according to the established structural model, and then expand the radiation area of ​​the tree to meet the needs of stable production and balance tree vigor. [0003] The traditional pruning is to thin out the stronger developing branches in the established tree structure, adopt the medium branches to cultivate flowers and bear fruit, and arrange the large-scale fruiting branch groups, medium-sized fruiting branch groups and small fruiting branch groups in proportion, and keep the developing branches. Appropriate short cutting, especially the developing branches of Dangshansu pear re...
