Okay, I need to create a Wikipedia-style document about apple cultivation under the categories of Economics, Agriculture, and Fruit Cultivation. Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3, and references if needed. The content should be accurate, objective, detailed, easy to read, and use technical terms with explanations. Also, markdown formatting with proper headings, lists, tables, code blocks where necessary, and at least 800 characters.

The title is "사과" (Apple). Let me outline the sections. Maybe start with an overview of apple cultivation in Korea or globally? Then break down into history, varieties, cultivation techniques, economic impact, challenges, etc.

For the introduction, I should mention where apples are grown, their importance in agriculture, maybe some stats on production. Then under H2, perhaps "역사" (History) and "주요 품종" (Main Varieties). For each variety, use H3 to detail specific types like Red Delicious or Fuji.

Next, cultivation techniques: climate requirements, soil conditions, planting methods, pruning, pest control. Maybe a section on sustainable practices. Then economic aspects: market value, trade, challenges like climate change or pests.

I need to ensure technical terms are explained. For example, "적온" (chilling requirement) should be defined. Also, include some data, maybe production numbers from Korea's agricultural statistics.

Check for accuracy: Are the main apple varieties in Korea correctly listed? What about cultivation practices specific to South Korea? Maybe mention regions like Gyeongsang or Gangwon provinces where apples are grown.

Include a section on challenges and future trends. Maybe discuss climate change effects, organic farming trends, or new technologies in orchard management.

References: If I use data from sources like the Korean Agricultural Statistics or FAO, cite them properly. But since it's a wiki-style document, maybe just mention the sources without formal citations.

Make sure each section flows logically. Use bullet points for lists of varieties or techniques. Maybe a table comparing different apple types by origin, characteristics, and uses.

Check the length: 800 characters is about 150-200 words. The example response provided earlier was longer, so I need to elaborate more on each section. Add details like specific cultivation steps, examples of pests and diseases, and their management methods.

Avoid markdown in the thinking process but ensure it's applied correctly in the final document. Use H1 for the title, H2 for main sections, H3 for subsections. Highlight key terms with bold or italics if needed, but follow the user's instruction to use code blocks for technical content.

Double-check that all information is accurate and up-to-date. For example, current production figures in Korea, popular apple varieties there, and any recent advancements in apple cultivation techniques.
