Exposed renewal and transformation method for citrus reticulita

Abstract

The invention relates to the technical field of fruit tree cultivation, in particular to an exposed renewal and transformation method for citrus reticulita. The method comprises the following steps ofpruning in spring, wherein during January to April, 2-5 healthy skeleton branches are selected and reserved, other skeleton branches are sawed off from the stem base, retraction is carried out on theportion, of which the height is 1.0-1.5 meters, of the selected and reserved skeleton branches, a stake is not reserved and boughs on the skeleton branches are cut off, auxiliary branches of which the diameters are less than or equal to 0.5 centimeter are reserved as far as possible, and if branch tips are crossed, overlapped or closed, short pruning or retraction is carried out on the branch tips; a protective agent is applied on a pruned large wound; during April to May, sprouts, with the distance less than 50 centimeters from the ground, of the skeleton branches are removed; during April to July, a disease and insect pest prevention pesticide is applied; pruning in summer, wherein during late June to late July, 10-20 centimeters of newly grown shoots extracted from the skeleton branches are reserved for short pruning; ripening of autumn shoots is promoted, and flower bud differentiation is completed. The method has the advantages of being simple and high in transformation efficiency.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to an explicit renewal and transformation method for Nanfeng tangerine. Background technique [0002] As a traditional characteristic variety in my country, Nanfeng Tangerine has been cultivated for more than 1,300 years. It is deeply loved by consumers because of its thin skin, bright color, small and cute fruit, juicy, sweet and sour taste, and strong aroma. However, Nanfeng tangerine has strong germination and branching ability. If it is not properly managed, it will easily lead to problems such as many backbone branches, dense inner chambers, and tall crowns. In recent years, due to the shortage of labor force and the increase of labor costs, the management of orange orchards has become more and more extensive and inadequate, resulting in the closure of many orchards, and the rapid decline in yield, quality and orchard benefits; The dead branches and fruiting par...

AI Technical Summary

Problems solved by technology

This technique is relatively simple, but it does not consider the skeleton configuration when restoring the canopy, resulting in the restoration of the canopy is still relatively large

On the other hand, there is also a lack of further technology at present, which leads to the fact that the tree body with direct crown reduction basically cannot produce fruit in the second year after the transformation, or the fruit is very little.
