A method of shaping and pruning bayberry multi-main branch dwarfing round-headed tree structure

Abstract

The invention discloses a pruning and trimming method for a multi-branch dwarf-round-head type strawberry tree body structure. The pruning and trimming method includes: after field planting of 4-year seedlings, subjecting main branches of the seedlings after field planting to branch holding and drawing in the first and second year to control horizontal basal angles of the branches; cultivating secondary branches and large lateral branches; after the third year, for spring twigs and early autumn twigs retracting by one third, removing the weak and keeping the strong, appropriately thinning stems, strengthening vigorous twigs, fully pruning away late autumn twigs, timely removing and retracting the lateral branches which are over-crowded, intersected and away from backbone branches, and keeping the crown with ventilation and penetrating light inside; after the fifth year and entering the full productive age, controlling the height of the tree to be from 2.5m to 3.0m and the crown to be 3.0m to 3.5m, and maintaining the obtained multi-branch dwarf-round-head type strawberry tree body structure. The pruning and trimming method has the advantages that through field planting, trimming and pruning of the 4-year seedlings, the height of the tree body is effectively reduced, the tree body is dwarfed, picking difficulty and management cost are reduced, high and stable yield of strawberries is promoted, and quality of the strawberries is improved.

Description

technical field [0001] The invention relates to the technical field of fruit tree shaping, in particular to a method for shaping and pruning a bayberry multi-main branch dwarfed round-headed tree structure. Background technique [0002] Bayberry is a specialty fruit in my country. Ningbo is one of the origins of bayberry. According to the statistics of Ningbo Municipal Bureau of Statistics in 2015, the area of ​​bayberry gardens in the city was 265,000 mu in 2014, accounting for 34.8% of the city's orchard area. It is the fruit type with the largest cultivated area. . Yangmei has a long history of cultivation in our city, and the traditional extensive management mode is still the main method at present. Most of the bayberry trees are tall, and the height can reach more than 10m. The tall trees lead to a late fruiting period, unstable yield and quality, and difficulty in applying modern production techniques. , Increase the cost and difficulty of picking, and the mature perio...

My city has a long history of bayberry cultivation, and the traditional extensive management mode is still the main method at present. Most of the bayberry trees are tall, and the height can reach more than 10m. The tall trees lead to a late fruiting period, unstable yield and quality, and difficulty in applying modern production techniques. , Increase the cost and difficulty of picking, and the mature period of bayberry coincides with the rainy season, and the tree is slippery, causing safety hazards, and there are incidents of injuries caused by bayberry picking every year
