Problems solved by technology

These reasons make it impossible for the south to use the tree shape suitable for mechanized production in the north. Therefore, fruit farmers need a high-efficiency peach cultivation model suitable for facility conditions that is convenient for mechanized operation, high in fruit quality, and less in growth.

Embodiment 1

[0039] Variety: Huyou 277, nectarine, matured on June 15th, planted in a multi-span greenhouse in the Zhuanghang Experimental Base of the Academy of Agricultural Sciences, Fengxian District, Shanghai. The greenhouse is 100m long, 64m wide, and 8-span. Planting time in spring 2016. The planting density is 4m×4m, and 42 plants are planted in the north-south direction.

[0040] The fixed stem height is 30-50cm on the grafting interface, leaving 4-6 full buds. The first terminal bud under the cut is facing the row direction, and the new growth in May-June is like figure 2 As shown, select two strong branches in the north-south direction as the main trunk, and remove the remaining branches. The distance between the two main branches is greater than 10cm. Keep the two main branches at the same height by retracting or shortening, and then manage them normally. Maintain the top growth advantage of each main branch, and promptly remove, sprain or severely cut side branches that aff...

Embodiment 2

[0090] Variety: 'Huyou 338', yellow peach, matured on June 18, planted in multi-span greenhouses with a length of 100m and a width of 64m, with 8 multi-spans. The planting time is the spring of 2016. The planting density is 4m×4m, and 42 plants are planted in the north-south direction.

[0091] The fixed stem height is 30-50cm on the grafting interface, leaving 4-6 full buds. The first terminal bud under the cut is facing the row direction. From May to June, according to the new growth situation, select two strong growing branches in the north-south direction as the main trunk, and remove the remaining branches. The distance between the two main branches is greater than 10cm, and the two main branches are kept at the same height by retracting or shortening. Manage normally thereafter. Maintain the top growth advantage of each main branch, and promptly remove, sprain or severely cut side branches that affect the extension and growth of the main branch.

Abstract

The invention provides a method for pruning a planar tree shape of four main branches and its application in cultivation, and relates to the technical field of peach tree cultivation. The pruning method of the present invention comprises: 1) setting the stem at 30-50 cm above the grafting joint of the peach tree; 2) selecting two strong branches in the north-south direction from May to June as the main trunk; , respectively insert two bamboo poles on both sides of the peach tree plant, and pull the main trunk to the outermost two bamboo poles respectively; New main trunks are drawn to the inner bamboo poles respectively; the new main trunks grow vertically upwards. The tree shape of the present invention can disperse nutrition to each main trunk, the number of elongated branches of the tree body is small, and the overall pruning requires less labor; the fruit yield in the upper part of the tree body is increased, the proportion and quality of large fruits are increased; and the row space is increased.

Description

technical field [0001] The invention belongs to the technical field of peach tree cultivation, and in particular relates to a method for pruning a planar four-main-branch tree shape and its application in cultivation. Background technique [0002] In the Shanghai area, land rent and labor costs are getting more and more expensive, and the benefits of conventional cultivation are low. Therefore, many orchards have been transformed into picking orchards to increase orchard income. Under protected cultivation conditions, strange, high-quality, and special peach varieties can be planted, such as flat peaches, nectarines, and nectarines. These varieties are greatly affected by the weather. When cultivated in the open field, the fruit cracking is often serious, and the commercial fruit rate is low. Facility cultivation can reduce the impact of weather on fruit quality and picking activities and promote early fruit ripening. Therefore, facility cultivation of peach trees has become...
