Okay, I need to create a Wikipedia-style document about "Grafting" under the categories of Agriculture, Cultivation Methods, and Seedling Selection. Let me start by understanding what grafting is. Grafting is a horticultural technique where parts from two different plants are joined so they grow together. The main goal is to combine the rootstock's desirable traits with the scion's characteristics.

First, I'll structure the document with an H1 title: "그라프트 (Grafting)". Then an overview section explaining what grafting is and its importance in agriculture. Next, I need several sections. Maybe start with the definition and purpose of grafting. Then move into types of grafting methods, like cleft grafting, whip and tongue, etc. Each method can be an H2 or H3 heading.

I should also include the benefits and challenges of grafting. For example, disease resistance, improved yield, but also the skill required. Maybe a section on selecting suitable rootstock and scion. Also, steps involved in the process. Need to make sure technical terms are explained, like "rootstock" and "scion".

I need to check if there are different types of grafting methods. Let me recall: cleft grafting, whip and tongue, bud grafting, etc. Each has its own application. Also, maybe mention the timing for grafting, like during certain seasons.

For the references, I can include some agricultural resources or textbooks. Make sure all information is accurate and objective. Avoid any subjective statements. Keep the language clear and concise. Use bullet points or lists where possible to enhance readability.

Wait, the user mentioned 800 characters minimum. The current draft might be too short. Need to expand each section with more details. For example, under types of grafting, elaborate on each method's steps and when they're used. Add examples of plants commonly grafted. Maybe include a table comparing different methods.

Also, ensure that the introduction sets the context properly, explaining why grafting is important in agriculture. Mention historical use or modern applications. Check for any common mistakes in grafting and how to avoid them. Maybe add a section on best practices or tips for successful grafting.

I should also verify if there are any specific challenges in grafting, like compatibility issues between rootstock and scion, or environmental factors affecting the success rate. Include that in the challenges section.

Make sure all sections flow logically from one to another. Start with overview, then types, benefits, selection criteria, steps, challenges, and references. Use H2 for main sections and H3 for subsections if needed. Avoid markdown formatting beyond what's specified, like using bold or italic where necessary.

Double-check the terminology: rootstock is the plant that provides the roots, scion is the part that provides the shoots. Explain these terms in the introduction. Maybe use a diagram reference, but since it's text-based, describe the process instead.

Alright, putting it all together now, ensuring each section meets the requirements and the total length is sufficient.
