Scope: This document specifies the terminology and definitions of light, simple, and efficient cultivation techniques for lychee orchards, including weed cultivation, mechanized tree shape cultivation, pruning, shoot control, flower induction, flower thinning, pest and disease prevention, and facilities and equipment requirements. This document applies to the light, simple, and efficient cultivation of mature lychee orchards. Main technical content: 1. Terminology and definitions The following terms and definitions apply to this document: 1.1 Sod-mulching The practice of covering the inter-row space of fruit orchards with natural or artificially grown grass. 1.2 Heavily retractive pruning The method of reducing the height of tall and dense fruit trees by pruning low branches, facilitating management. 1.3 Controlling winter shoots Using physical or chemical methods to inhibit or control the growth of winter shoots. 1.4 Flower thinning Removing or reducing the number of flower clusters using physical or chemical methods. 1.5 Bark grafting A grafting method that selects a smooth bark surface on the rootstock for grafting.
