Scope

Scope: This document specifies the technical requirements for the green production of Shixia longan, including terminology and definitions, tree management, fertilization management, and green prevention and control of diseases and pests, as well as fruit harvesting. This document applies to the green production management of mature Shixia longan trees. Main technical content: 1. Terminology and definitions: The following terms and definitions apply to this document. 1.1 Shixia longan: A plant of the Sapindaceae family (Longan Sonn.) and a type of evergreen tree. Shixia longan is the current main cultivar used for commercial production. 1.2 Adult tree: A longan tree that has entered the normal flowering and fruiting stage. 1.3 Flush protection: After fruit harvesting pruning, protecting the new shoots from pests and diseases with physical or chemical methods. 1.4 Controlling winter shoots: After the last autumn shoots have matured, preventing winter shoots from sprouting by controlling their emergence with physical or chemical methods. 2. Tree management: 2.1 Post-harvest pruning: 2.1.1 Pruning is carried out 7-10 days after fruit harvesting to cultivate 1-2 new shoots. 2.1.2 For the first shoot, leave 2-3 buds on thick branches and 1-2 buds on medium- and thin-stem branches, while removing other buds promptly. 2.1.3 For the second shoot, leave only 1 bud, while removing other buds promptly. 2.1.4 Bud removal is carried out when the new shoots grow to 5-8 cm in length. 2.1.5 Remove crossed branches, diseased and pest-infested branches, weak branches, overly dense branches, and trailing branches. Keep the tree height within 3 m. 2.2 Shoot protection: Use biological and physical methods such as natural enemies, biocontrol bacteria, insect pheromones, and insect traps to protect shoots. 2.3 Shoot control: After the last autumn shoots have matured, stop fertilization and irrigation from late November to early December each year, and control shoots using methods suc
