A method for flowering and fruiting of axillary buds of young hickory trees with thin shells

Abstract

The invention discloses a sapling axillary bud flower formation technology for Carya illinoinensis (Wangenh.) K. Koch and belongs to the technical field of fruit tree cultivation. The technology comprises the steps that strong and good seedlings are selected and planted, management is carried out in the same planting year and the second year, the vigor of saplings is controlled, and flower forming and fruit bearing of sapling axillary buds are achieved. According to the technology, paclobutrazol is used for controlling nutritive growth of tree bodies and promoting reproductive growth, flower forming and fruit bearing of axillary buds are promoted with the cooperation of bud carving measures, the problems that only apical buds and 1-3 buds below each apical bud of Carya illinoinensis (Wangenh.) K. Koch saplings bear fruits, fruit bearing in an early stage is low, and the yield is low are solved, earlier fruit bearing of Carya illinoinensis (Wangenh.) K. Koch saplings can be promoted, and fruit bearing is achieved 1-2 years earlier.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a technique for forming flowers from axillary buds of young hickory trees with thin shells. Background technique [0002] Thin-shelled hickory [Carya illinoensis (Wangenh.) K. Koch], also known as long hickory, American thin-shelled hickory, is a deciduous tree of the genus Hickory in the family Juglandaceae. Its nuts are rich in nutrition and have high health care value. Studies have found that long-term consumption of pecan kernels with thin shells can significantly increase the content of γ-tocopherol in the blood, which can prevent aging, strengthen the stomach, and prevent prostate cancer. Walnuts are also rich in trace elements necessary for human body such as phosphorus, zinc, iron, calcium, magnesium, manganese, copper, selenium and nutrients such as vitamin E, B, 32 and coenzyme Q10. employee food". [0003] At the end of the 19th century and...

AI Technical Summary

Problems solved by technology

Thin-shell hickory has the habit of the top flower bud and the 1-3 axillary flower buds below it. The result is that the mother branches are mostly short and medium branches, while the growth potential of the young trees is strong, and most of the formed branches are long branches, resulting in few flower buds in the young trees. , low fruit set rate and low yield limit the development of the industry
