A novel bud-notching and pruning method realizing early fruiting and high yield of latefruiting juglans regia

Abstract

The invention provides a novel bud-notching and pruning method realizing early fruiting and high yield of late fruiting juglans regia. The method comprises steps as follows: in the first year of field planting, a planting stock is cut back to the bud enrichment part and sealed before field planting of the juglans regi planting stock; when planting stock shoots grow to 15-25 cm, a terminal bud is selected and reserved to be cultured into a central leader trunk; after main stem is basically mature, ungerminated lateral buds, higher than the heading height, on the mature main stem are all subjected to bud-notching, the bud-notching is performed once every 45-55 d from May to August and is performed twice in one year, bark in the position 2-3 cm above buds is slightly cut to the xylem by a knife, and crescent-shaped marks are formed. Therefore, the problems that an existing technology has serious defects, the effect is not obvious and the practicability is poor due to the fact that the existing technology isolates fruiting with high yield, only focuses on early fruiting and neglects high and stable yield are solved. The novel bud-notching and pruning method belongs to the technical field of agricultural cultivation.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a new method for pruning walnuts with late fruit, early fruit, high yield, and bud cutting. Background technique [0002] Walnut (Juglans regia): Also known as walnut, it is a deciduous tree of the family Juglandaceae and the genus Carya Nutt. Together with almonds, cashew nuts and hazelnuts, it is also known as the world-renowned "four major dried fruits". Walnuts are rich in nutrients, and contain essential calcium, phosphorus, iron and other trace elements and minerals, as well as carotene, riboflavin and other vitamins, which are very beneficial to the human body. It is one of the nut foods loved by the common people. my country is one of the origin and distribution centers of walnut plants, with a cultivation history of more than 2,000 years. [0003] Walnut has a wide range of adaptability, is resistant to thin ridges and extensive management, and is most...

Problems solved by technology

This method can only promote the germination of a few buds near the top, and after the top growth point is cut off, the branches need to stop growing for a period of time, and new buds will start to grow after the branches are mature, thus affecting the expansion of the canopy and the dominance
