Okay, I need to create a professional 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 advantages with the scion's desirable traits.

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 potential issues like incompatibility between rootstock and scion. Maybe a section on how to choose suitable plants for grafting, considering factors like compatibility, health, and environmental conditions.

Including examples help. mention common crops that use grafting, like fruit trees or vegetables. Also, the process steps: preparing the rootstock and scion, making the cut, securing them, and aftercare. Maybe a section on tools needed for grafting.

I need to ensure technical terms are explained. For instance, "rootstock" is the plant that provides the roots, while "scion" is the part that will grow into the desired plant. Also, mention different grafting techniques with their specific applications.

Check if there's a section on historical context or modern advancements in grafting. Maybe not necessary unless it adds value. Focus more on practical aspects for farmers and gardeners.

Need to make sure the document meets 800 characters. Let me outline each section:

1. Introduction: What is grafting, its significance.
2. Types of Grafting Methods (with sub-sections).
3. Benefits and Challenges.
4. Selection Criteria for Rootstock and Scion.
5. Step-by- Process.
6. Examples in Agriculture.
7. Conclusion.

Now, write section with clear headings, use bullet points or lists where appropriate. Avoid markdown but since the user wants it in markdown format, I'll structure accordingly. Make sure to explain terms like "cleft grafting" and "whip and tongue" briefly. Also, mention tools like grafting knives, tape, etc.

Check for accuracy: Grafting is used in fruit trees, vegetables, ornamental plants. Benefits include disease resistance, faster growth, better yield. Challenges include compatibility issues, proper technique, aftercare.

Include references or related documents if needed, but maybe that's optional here. Ensure the language is clear and professional, avoiding overly technical jargon without explanation.
