Scope

Scope: This document specifies the cultivation of rootstocks for grafting and seedling production of pepper, preparation before grafting, grafting, post-grafting care, seedling quality and grading, and technical file management. This document is applicable to the grafting and seedling production of pepper; Main technical content: The technical indicators involved in pepper seedling production in this protocol, such as nursery site selection, rootstock cultivation, grafting, post-grafting care, seedling quality and grading, and technical file management, are all determined based on a comprehensive reference to published scientific papers, relevant technical regulations, cited documents, and acceptance reports of the project drafting group's achievements, selecting and determining them in accordance with the principles of advancedness, rationality, systematicness, and strong operability. I. Basis for Determining Indicators and Parameters 1. Grafting Time (1) Grafting time: According to the phenological period of pepper, grafting time is divided into five periods: bud start swelling period, leaf bud start swelling period, leaf unfolding start period, leaf unfolding peak period, and spring shoot start period. For each period, a grafting experiment was conducted using the cleft grafting method, with 50 seedlings per treatment and three replications. (2) Grafting survival rate: The grafting survival rate was investigated when the spring shoots stopped growing. The number of grafts with good healing and survival was investigated for each seedling, and the survival rate was statistically calculated. (3) High growth amount: After the autumn leaves fell, the high growth amount of each seedling was measured using a steel tape measure. 2. Grafting Methods This document determines the grafting methods as cleft grafting and double-tongue grafting. The determination basis is as follows: (1) Grafting method experiment: In the cultivation and production of grafted seedlings, cleft g
