Okay, I need to create a professional wiki-style document about "근종" (which translates to "grafting technique" in agriculture). Let me start by understanding the user's requirements.

First, the structure: H1 for the title, an overview section, several H2 and H3 sections, and maybe references. The content needs to be accurate, detailed, easy to understand, with some technical terms explained. Also, it should be over 800 characters long.

The main topic is "근종" under the categories of Agriculture -> Cultivation Techniques -> Grafting Methods. So I need to cover what grafting is, its importance in agriculture, different methods, steps involved, benefits, challenges, and maybe some references.

I should start with an introduction explaining what grafting is and why it's important. Then break down into sections like types of grafting techniques, the process, advantages, challenges, and perhaps a section on best practices or examples.

Need to make sure technical terms are explained. For example, "근종" itself might be a term that needs explanation. Also, different methods like cleft grafting, whip and tongue, etc., should be described with their steps and uses.

I should check if there are any common challenges in grafting, such as compatibility issues between rootstock and scion, environmental factors, or techniques to improve success rates.

Including examples of crops commonly grafted would add practical value. Maybe mention fruits like apples, citrus, or vegetables like tomatoes.

Also, need to ensure the document flows logically, each section building on the previous one. Use bullet points or lists for methods and steps to make it readable.

I should avoid being too technical without explanation but still maintain a professional tone. Make sure all information is accurate; maybe refer to standard agricultural practices.

Check that the length meets the requirement. Each section should be sufficiently detailed. Maybe 2-3 H2 sections with sub-sections (H3) for each method, steps, etc.

Finally, add references or related documents if needed, like links to more detailed guides or scientific studies.
