Tree form suitable for reconstruction of Xinjiang close planting date garden and pruning method thereof

Abstract

The invention discloses a tree form suitable for reconstruction of a Xinjiang close planting date garden and a pruning method thereof, and belongs to the technical field of agricultural gardening. The tree form of each date tree is designed as follows: the tree height is 1.8-2.5m; the trunk height is 40-45cm; 18-20 secondary branches are distributed in a spirally staggered manner along a central leader and grow on 3 layers; the first layer has 6-7 secondary branches, the length is kept at 7-9 knots, and the branching angle is 70-80 degrees or a natural one; the second layer has 7-8 secondary branches, the length is kept at 8-9 knots, and the branching angle is 80-90 degrees; the third layer has 4-5 secondary branches, the length is kept at 5-6 knots, and the branching angle is 100-110 degrees; the interlayer spacing is 25-35cm; and a tree crown appears as a layered cylindrical one with a bigger lower part and a smaller upper part. According to the invention, the crown form is reduced, thereby solving the problem of poor ventilation and light transmission after the date trees in a Xinjiang ultra-high-density close planting date garden are mature; the space is fully utilized for fruiting, so that the number of fruiting date spurs is increased, thereby solving the problem of fruiting part offset of the date trees; the shaping and pruning technology is simplified, and the labor cost is lowered; and the suitable tree form is provided for mechanization management of the Xinjiang close planting date garden.

Description

technical field [0001] The invention relates to the technical field of agriculture and horticulture, in particular to a tree shape suitable for the transformation of densely planted jujube gardens in Xinjiang and a pruning method thereof. Background technique [0002] As the fruit with the most ethnic characteristics, jujube has high edible value. Xinjiang jujube has bright color, thin skin, soft and sweet taste, and outstanding nutritional value. It is widely welcomed by jujube consumer groups, so it has very good market competitiveness and Development prospects, among them, the excellent quality of Xinjiang Junzao, compared with similar products, its fruit shape is large, thin skin, thick flesh, sweet and mellow taste, its vitamin C, protein, mineral content are higher than similar products, known as "China's first jujube", gray jujube is suitable for dense planting because of the positive correlation between early yield and branch volume, so Xinjiang Junzao and gray jujub...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is in order to overcome the problem in the prior art, provide a kind of tree form and pruning method thereof suitable for the transformation of densely planted jujube gardens in Xinjiang, the improved cylindrical tree shape suitable for the transformation of canopy closed jujube gardens, while maintaining the existing planting Under the condition of density, the tree shape is transformed in rows, which not only does not cut down the jujube trees, but also solves the problem of ventilation and light transmission in the jujube orchard, and is conducive to the mechanized management of the jujube orchard, saving labor and cost
