Method for accelerating blossoming and fruiting of citrus high-grafting variety by adopting inter-stock combination

Abstract

The invention discloses a method for accelerating blossoming and fruiting of a citrus high-grafting variety by adopting an inter-stock combination. The method comprises the steps of (1) selection of the inter-stock combination; (2) determining an inter-stock cultivation mode; (3) determining a grafting time; (4) performing grafting; (5) carrying out management after grafting; and (6) performing flower and fruit management. According to the method, fructus aurantii-smooth-skin kumquat is taken as the citrus high-grafting variety inter-stock, advanced and easy blossoming and fruiting is achievedcompared with that adopting shaddock type, orange type, lemon type and wide-skin citrus type as the inter-lock, and identification and evaluation of new species can be rapidly carried out; and the citrus, after being high-grafted by the method of the invention, can blossom and fruit in the second year, and character of early blossoming and fruiting can be realized, and early citrus variety identification is facilitated, thereby accelerating the variety test and utilized, shortening the breeding period and promoting the breeding benefits.

Description

technical field [0001] The invention belongs to the technical field of citrus high-grained intermediate stock, in particular to a method for accelerating the flowering and fruiting of citrus high-grained varieties by adopting the combination of intermediate stock. Background technique [0002] Citrus high-grafting technology is the main measure for variety renewal and germplasm resource preservation and identification, and is widely used at home and abroad. The traditional high-grained intermediate stock generally chooses the same or similar varieties as the scion. The goal of high-grained grafts is to survive in one year, crown in two years, bear fruit in three years, and high yield in four years. However, some varieties, such as pomelo, orange, etc., take a long time to flower and bear fruit after high-grafting on the same kind of intermediate stock, and it often takes 2-3 years to start to bloom and bear fruit. Moreover, citrus is a perennial woody fruit tree, and the bre...

Problems solved by technology

However, some varieties, such as pomelo, orange, etc., take a long time to flower and bear fruit after high-grafting on the same kind of intermediate stock, and it often takes 2-3 years to start to bloom and bear fruit. Moreover, citrus is a perennial woody fruit tree, and the breeding cycle is long, which is not conducive to Accelerate the identification and evaluation of varieties and the selection and utilization of breeding
