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. The planting time is the spring of 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 branch...

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 trimming method of a planar four-main-branch tree form and application in culturing thereof, and relates to the technical field of peach tree culturing. The method comprises the steps that one, heading is conducted at the part 30-50 cm above a grafting hole of a peach tree; 2), two branches with strong growing trend growing in the row in the direction from south to north are selected as trunks from May to June; 3), two bamboo poles are inserted on the two sides of a peach tree plant in July, and the two trunks are drawn towards the two bamboo poles on the outermost sides respectively; 4), secondary shoots close to a heading point on the trunks are selected as new trunks in August, and the new trunks are drawn to the bamboo poles on the inner sides respectively; thenew trunks grow vertically upwards. According to the method, nutrients can be dispersed to each trunk by the tree form, the number of spindling branches of a tree body is low, the labor force used onintegrally trimming is less, fruit yield on the upper middle part of the tree body is increased, big fruit proportion is increased, the quality is improved, and the space in row direction 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...
