A method for accelerating the flowering and fruiting of citrus high-grafted varieties by using an interstock combination

Abstract

The invention discloses a method for accelerating the flowering and fruiting of citrus high-grafted varieties by using an interstock combination. The operation steps are (1) selection of an interstock combination; (2) an interstock cultivation method; (3) grafting time; (4) grafting ; (5) Management after grafting; (6) Flower and fruit management. The present invention adopts "citrus aurantium-smoothing kumquat" as the interstock of citrus high-connection varieties, which is earlier and easier to bear fruit than interstocks such as pomelo, orange, lemon, broad-skinned citrus, etc., and can quickly carry out identification and evaluation of new varieties; The method of the invention can flower and bear fruit in the second year after high grafting, and can achieve flowering and fruit characters as soon as possible, which is beneficial to early identification of citrus varieties, accelerates variety testing and utilization, shortens the breeding cycle and promotes breeding benefits.

Description

technical field [0001] The invention belongs to the technical field of high-connected citrus interstocks, in particular to a method for accelerating the flowering and fruiting of high-connected citrus varieties by using an interstock combination. Background technique [0002] Citrus high access technology is the main measure for variety renewal and germplasm resource conservation and identification, and is widely used at home and abroad. The traditional high-grafted intermediate stock is generally the same or similar variety as the scion. The goal of high-grafting is to survive in one year, crown in two years, bear fruit in three years, and achieve high yield in four years. However, some varieties, such as pomelo, orange, etc., take 2-3 years to flower and bear fruit after high grafting on similar intermediate stocks, and citrus is a perennial woody fruit tree with a long breeding cycle, which is not conducive to Speed ​​up variety identification, evaluation, breeding and u...

AI Technical Summary

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
